workout 1/3 divided by 7/6 plus 1/5
Answers
Answer: To simplify the expression, we need to follow the order of operations, which is to perform the division first, then addition.
1/3 ÷ 7/6 + 1/5
To divide fractions, we need to multiply the first fraction by the reciprocal of the second fraction:
1/3 ÷ 7/6 = 1/3 × 6/7 = 2/7
Now we can substitute this value back into the original expression:
2/7 + 1/5
To add fractions with different denominators, we need to find a common denominator. In this case, the common denominator is 35:
2/7 × 5/5 = 10/35
1/5 × 7/7 = 7/35
Now we can add the two fractions:
10/35 + 7/35 = 17/35
Therefore, the simplified expression is 17/35.

The parabola's equation is as follows, with the directrix at y = 5 and the focus at (-4, 3). [tex](x + 4)^2 = 4y - 16[/tex]
what is parabola ?A hyperbolic is a U-shaped symmetry curve that is created when a plane and a cone collide. The parabola has the characteristic that the distance between any point on the curve and a fixed point (referred to as the focus) is identical to the distance between that point and a telephone service (called the directrix). Equation y = ax2 + bx + c, at which a, b, and c are constants, gives the conventional form of a parabola. The parabola opens either upwards or downwards depending on the sign of coefficient a. The arc opens upwards if an is positive and downwards if an is negative.
given
A parabola with a vertex at (h, k) and a vertical axis of symmetry has the following standard form equation:
[tex](x - h)^2 = 4p(y - k) (y - k)[/tex]
where p is the separation between the vertex and the directrix or focus.
In this instance, the vertex's coordinates are (h, k) = since it is located halfway between the focus and directrix (-4, 4). As the directrix is a horizontal line with the coordinates y = 5, the separation between it and the vertex is p = 1.
When we enter these values into the equation in standard form, we obtain:
[tex](x + 4)^2 = 4(1)(y - 4) (y - 4)[/tex]
If we simplify, we get:
[tex](x + 4)^2 = 4y - 16[/tex]

The correct sequence of transformations that proves AMNO and APQR are congruent is: OAMNO was dilated by a factor of 3 about the origin, then reflected across the y-axis to form APQR.
The sequence of transformations proves AMNO APQRThe correct sequence of transformations that proves AMNO and APQR are congruent is:
OAMNO was dilated by a factor of 3 about the origin, then reflected across the y-axis to form APQR.
To see why, let's examine the properties of the two triangles:
Triangle MNO has vertices at (-2,-1), (-2,4), and (3,1).
Triangle PQR has vertices at (-6,-3), (-6,12), and (9,3).
If we dilate triangle MNO by a factor of 3 about the origin, we get a new triangle with vertices at (-6,-3), (-6,12), and (9,3). This is because each coordinate of MNO is multiplied by 3:
(-2,-1) -> (-6,-3)
(-2,4) -> (-6,12)
(3,1) -> (9,3)
If we reflect this new triangle across the y-axis, we get a new triangle with vertices at (6,-3), (6,12), and (-9,3). This is because the x-coordinates of each point are negated:
(-6,-3) -> (6,-3)
(-6,12) -> (6,12)
(9,3) -> (-9,3)
This final triangle, with vertices at (6,-3), (6,12), and (-9,3), is congruent to triangle PQR. Therefore, we have shown that AMNO and APQR are congruent.

The seats available to a baseball game come in four types: bleacher, box, club, and grandstand. There are 12,600 box seats and 5,400 club seats available. According to the graph, what is the total number of seats available?
Answers
Answer: 45,000
Step-by-step explanation:
Let x be the total number of seats available. According to the problem, 18% of the seats are bleachers, and 42% of the seats are grandstands. That means the remaining 40% of the seats are box and club seats combined since 100% - 18% - 42% = 40%.
The problem states that there are 12,600 box seats and 5,400 club seats available, which makes a total of 12,600 + 5,400 = 18,000 box and club seats.
Now, we can set up an equation to find the total number of seats:
0.40x = 18,000
To solve for x, divide both sides of the equation by 0.40:
x = 18,000 ÷ 0.40
x = 45,000
There are a total of 45,000 seats available at the baseball game.

What is equation?Variable words are commonly used in complex algorithms to show consistency between two contradictory claims. Academic expressions called equations are used to show the equality of various academic numbers. Think about the information that y + 7 provides. When accompanied by generate y + 7, increasing results in b + 7 in this case rather than another method that could split 12 into two separate components.
Here,
We must enter t = 110 into the equation for y and solve for y in order to determine how much of the original mass is still present after 110 years:
=> y = 20(1 - 2^(-t/30))
=> y = 20(1 - 2^(-110/30))
=> y ≈ 2.517
As a result, there are roughly 2.517 grams of cesium-137 left after 110 years. We can deduct this amount from the original mass of 20 grams to determine how much of the initial mass is still present:
=> 20 - 2.517 ≈ 17.483
Thus, roughly 17.483 grams of the original 20 grams of cesium-137 are still present after 110 years.

The value of the y -intercept is -4 and the slope of the equation is 1/2.
What is slope of the equation?A line's steepness and direction are measured by the line's slope. Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all.
Any two different points on a line may be used to compute the slope of any line. The ratio of "vertical change" to "horizontal change" between two different locations on a line is calculated using the slope of a line formula.
The slope of the line is given by the formula:
m = y2 - y1 / x2 - x1
From the table the coordinates are: (-6, -7) and (2, -3).
m = -3 + 7 / 2 + 6
m = 4 / 8
m = 1/2
Now, using the slope intercept form we have:
y - y1 = m(x - x1)
y + 7 = 1/2 (x + 6)
2 (y + 7) = x + 6
2y + 14 = x + 6
2y = x - 8
The y- intercept is found when x = 0
Thus, 2y = -8
y = -4
Hence, the value of the y -intercept is -4 and the slope of the equation is 1/2.

Parents wish to have $130,000 available for a child's education. If the child is now 10years old, how much money must be set aside at 3% compounded semiannually to meet their financial goal when the child is 18?
Answers
To reach their financial objective of having $130,000 accessible for their child's schooling when the youngster turns 18, the parents must set aside roughly $97,209.87 at 3% compound semiannually.
To determine how much money needs to be set aside to meet the financial goal of $130,000 for the child's education, we can use the compound interest formula:
[tex]A = P(1 + r/n)^(nt)[/tex]
where A represents the future value, P represents the principal (or initial investment), r represents the annual interest rate, n is the frequency with which interest is compounded annually, and t represents the passage of time in years.
To solve for the principal, P, in this situation, we must first identify the principal, P.
[tex]P = A / (1 + r/n)^(nt)[/tex]
Given that the child is currently 10 years old and will need the money in 8 years (at age 18), we have t = 8. The interest rate is 3%, which we need to express as a decimal (r = 0.03), and the interest is compounded semiannually, so n = 2.
Using these values and the desired future value of $130,000, we can calculate the required principal:
P = [tex]130000 / (1 + 0.03/2)^(2*8)[/tex] = $97,209.87

The polynomial of degree 3, p(x),has a root of multiplicity 2 at x=2 and root of multiplicity 1 at x=-4 the y intercept is -3.2
Answers
p(x) = k(x-2)^2(x+4)
where k is some constant.
To find the value of k, we use the fact that the y-intercept is -3.2, which means that p(0) = -3.2. Substituting x=0 into the equation for p(x), we get:
p(0) = k(-2)^2(4) = 16k
Setting this equal to -3.2, we have:
16k = -3.2
k = -0.2
So the polynomial is:
p(x) = -0.2(x-2)^2(x+4)
Therefore, the polynomial of degree 3, p(x), with a root of multiplicity 2 at x=2 and root of multiplicity 1 at x=-4, and y-intercept of -3.2, is given by:
p(x) = -0.2(x-2)^2(x+4)
the length of an instant message conversation is normally distributed with a mean of 5 minutes and a standard deviation of 0.7 minutes. what is the probability that a conversation lasts longer than 6 minutes?
Answers
The probability that a conversation lasts longer than 6 minutes is approximately 0.0764 or 7.64%.
What is probability?
The probability of an event is a figure that represents how probable it is that the event will take place. In terms of percentage notation, it is stated as a number between 0 and 1, or between 0% and 100%. The higher the probability, the more probable it is that the event will take place.
We can use the standard normal distribution to solve this problem by standardizing the variable using the formula:
z = (x - μ) / σ
where x is the value we want to find the probability for, μ is the mean, and σ is the standard deviation.
In this case, we want to find the probability that a conversation lasts longer than 6 minutes, so x = 6, μ = 5, and σ = 0.7. Substituting these values into the formula, we get:
z = (6 - 5) / 0.7 = 1.43
Next, we can use a standard normal distribution table or a calculator to find the probability that a standard normal random variable is greater than 1.43. Using a standard normal distribution table, we find that this probability is approximately 0.0764.
Therefore, the probability that a conversation lasts longer than 6 minutes is approximately 0.0764 or 7.64%.

Use a sum or difference identity to find the exact value. sin 10° cos 50° + cos 10° sin 50°
Answers
Answer:
√3/2
Step-by-step explanation:
sin(10°) • cos(50°) + cos(10°) • sin(50°)
= sin(10 + 50)
sin(60°) = √3/2
= √3/2
Step-by-step explanation:
We can use the sum identity for the sine of the sum of two angles to simplify the expression:
sin(a + b) = sin(a) cos(b) + cos(a) sin(b)
In this case, let a = 10° and b = 50°. Then we have:
sin(10° + 50°) = sin(10°) cos(50°) + cos(10°) sin(50°)
The value of sin(10° + 50°) can be calculated using the sum-to-product identity for the sine function:
sin(a + b) = sin(a) cos(b) + cos(a) sin(b)
sin(10° + 50°) = sin(10°) cos(50°) + cos(10°) sin(50°)
sin(60°) = sin(10°) cos(50°) + cos(10°) sin(50°)
sqrt(3)/2 = sin(10°) cos(50°) + cos(10°) sin(50°)
Therefore, the exact value of the expression is:
sin 10° cos 50° + cos 10° sin 50° = sqrt(3)/2
We can write it as:
sin 10° cos 50° + cos 10° sin 50° = √3/2
So, the answer is √3/2.
Pearl's Plumbing initially estimated the cost to fix Terrell's sink at $450. Fortunately for
Terrell, the prediction was 12.5% more than the actual cost. What was the actual cost of the
repair?
Answers
According to the given data the actual cost of the repair was $393.75.
What is meant by estimated cost?Estimated cost refers to the approximate amount of money that is expected to be spent on a particular project, task, or item. It is a prediction of the expected cost based on the available information and assumptions about the project or item being estimated. Estimated costs can be based on various factors such as labor, materials, equipment, overhead, and other expenses.
According to the given information:If the estimated cost was 12.5% more than the actual cost, then the actual cost was 100% - 12.5% = 87.5% of the estimated cost.
Let x be the actual cost of the repair. Then, we can set up the following equation:
87.5% of estimated cost = actual cost
0.875 * 450 = x
Solving for x, we get:
x = $393.75
Therefore, the actual cost of the repair was $393.75.

You deposit $6000 in an account earning 7% interest compounded monthly. How much will you have in the account in 15 years?
Answers
Answer:
$67,000 after 15 years.
Step-by-step explanation:
You deposit $6000 in an account earning 7% interest compounded monthly. How much will you have in the account in 15 years? account will have $67,000 in it after 15 years
A = P(1 + r/n)^(nt)
where:
A = the total amount in the account after t years
P = the principal amount (the initial deposit)
r = the annual interest rate (as a decimal)
n = the number of times the interest is compounded per year
t = the number of years
In this case, we have:
P = $6000
r = 0.07 (7% as a decimal)
n = 12 (compounded monthly)
t = 15
So we can plug these values into the formula:
A = $6000(1 + 0.07/12)^(12*15)
A = $6000(1.00583)^(180)
A = $6000(2.1961)
A = $13,176.60
Therefore, you will have $13,176.60 in the account after 15 years.

Rewrite each equation without absolute value symbols for the given values of x. y=|2x+5|-|2x-5|
if x<-2.5
if x>2.5
if -2.5<=x<=2.5
Answers
Answer: For x < -2.5:
y = |2x + 5| - |2x - 5|
y = -(2x + 5) - (-(2x - 5)) (since 2x - 5 < 0 and 2x + 5 < 0 for x < -2.5)
y = -2x - 5 + 2x - 5
y = -10
For x > 2.5:
y = |2x + 5| - |2x - 5|
y = 2x + 5 - (2x - 5) (since 2x - 5 < 0 and 2x + 5 > 0 for x > 2.5)
y = 10
For -2.5 ≤ x ≤ 2.5:
y = |2x + 5| - |2x - 5|
y = 2x + 5 - (-(2x - 5)) (since 2x - 5 < 0 and 2x + 5 > 0 for -2.5 ≤ x ≤ 2.5)
y = 4x

What in mathematics is a congruence?Congruent refers to having the same size and shape. Congruent hence involves comparing two numbers, and equivalent denotes the equality of two expressions. Hence, to state two line segments are congruent implies that the two lines have equal measurements.
Congruent implies a similar angle, right?Angle measure is the same for congruent angles. An ordinary pentagon, for instance, has five sides and five angles, each of which is 108 degrees. The angles of a regular polygon will always be congruent, regardless of its size or scale.
here, from given figure we have triangle ABC ,where
ABC is translation,
A'B'C' is rotation of triangle ABC
A''B''C'' is reflection ,
so,
the sequence of the transformations of triangle ABC is translation, then rotation, then reflection.

Find the volume. Round to two decimal places if necessary. If your answer is correct you will see an image appear on your screen.
Answers
The formula for finding the volume of a cone is [tex]\pi[/tex][tex]r^{2}[/tex] [tex]\frac{h}{3}[/tex]
Please note the following:
Radius: 5 in
Height: 13 in
(1): Substitute the radius and height into the equation.
[tex]\pi[/tex][tex](5^{2})[/tex][tex](\frac{13}{3} )[/tex]
(2): Using a calculator, solve the equation.
[tex]\pi[/tex][tex](5^{2})[/tex][tex](\frac{13}{3} )[/tex] = 340.33
(3): Round
If you were to round 340.33 to the next two decimal places, you'd get 340 as your final answer.
With that being said, the answer to your question is 340 in.
Rosa and Clarice have left over bread (not including the end pieces), so they decided to make sandwiches for the librarian, office staff, and custodian. How many sandwiches will they be able to make?
Answers
The number of sandwiches Rosa and Clarice can make depends on the amount of leftover bread they have.
To determine the number of sandwiches that Rosa and Clarice can make, we need to know how much bread they have.
Let's assume that they have 10 slices of bread left over. To make a sandwich, you typically use two slices of bread, so we can make 5 sandwiches with 10 slices of bread.
However, if they have more or less bread, the number of sandwiches they can make will change accordingly.
