Find the slope of the line.


A. –3

B. [tex]-\frac{1}{3}[/tex]

C. 3

D. [tex]\frac{1}{3}[/tex]

Answer:

k < 10

Step-by-step explanation:

An inequality is a statement of an order relationship—greater than, greater than or equal to, less than, or less than or equal to—between two numbers.

Let k represent Ken. The closed side of < is the side the smaller number is going to be on. Ken has fewer marbles then Joe, therefore, k < 10 because Joe has 10 marbles.

Answer:

[tex]x + 5y = 6[/tex] is perpendicular to [tex]y = 5x + \frac{6}{5}[/tex] and parallel to [tex]y = -\frac{1}{5}x + 2\\[/tex]

Step-by-step explanation:

First, convert the equation to standard form so that y is isolated.

x + 5y = 6 --> x - 6 = -5y (divide both sides by -5) --> [tex]y = -\frac{1}{5}x + \frac{6}{5}[/tex]

A perpendicular line will have a slope that is the opposite reciprocal of the original slope (meaning you flip the numerator and denominator then make it negative).

[tex]-\frac{1}{5}[/tex] is perpendicular to [tex]-(\frac{-5}{1} )[/tex] which simplifies to 5.

A parallel line will have the same slope, but the y-intercept will be different. It can be pretty much any number as long as the original slope is used in the new equation.

[tex]y = -\frac{1}{5}x + \frac{6}{5}\\[/tex] is parallel to [tex]y = -\frac{1}{5}x + 2\\[/tex] just like [tex]y = -\frac{1}{5}x - \frac{100}{23}[/tex].

The perimeter of a trapezoid is 28ft.

An isosceles trapezoid is a trapezoid whose non-parallel sides (the legs) are equal in length.

The perimeter of an  isosceles trapezoid (P) = a + b+ 2c

where a is the top, b is the bottom, and c is the leg of the trapezoid

According to the question,

perimeter = 38ft

leg of an isosceles trapezoid = 8ft

        38 = a +b +2 × 8

    ⇒ 38 = a+b +16

   ⇒a +b = 38 -16

    ⇒a +b = 22

Another similar trapezoid has a leg measuring 3ft.

Perimeter of this trapezoid is =( 22 + 2× 3) ​ft

                                                   = (22 +6)ft

                                                   = 28 ft

So, the perimeter of a trapezoid is 28ft.

The margin of error is $148.89. The upper limit is $2215 and lower limit is $1914.

In statistics, confidence is another word for probability. If you create a confidence interval, for instance, with a 95% level of confidence, you can be sure that 95 out of 100 times, the estimate will fall between the upper and lower values indicated by the confidence interval.

First we need to name some of the variables we are given:

n = 38 the sample size

x = 6.88 the sample mean

= 1.86 the population standard deviation

We need to find a 90% confidence interval for the mean price per 100 lbs of watermelon:

= 1-.90 = .10

/2 = .05

z(/2) = -1.64

-z(/2) = 1.64

This can give us a probability expression:

P(-1.645 < z < 1.645) = .90

The margin of error is calculated with the formula: E = z(/2)(/√n)

E = 1.645(1.86/√38) = $.4963(300) = $148.89  

Then to calculate the upper and lower limit we add and subtract E from x:

lower limit = 6.88 - .4963 = $7.38(300) = $2214

upper limit = 6.88 + .4963 = $6.38(300) = $1914

(a) The complete table

[tex]\begin{array}{cccccc}Hours & {1} & {2} & {3} & {4} &{5}\ \\ {Amount} & {\$9.50} & {\$19.00} & {\$28.50} & {\$38.00} & {\$47.50} \ \end{array}[/tex]

(b) $38.00

(c) 3 hours

Step-by-step explanation:

Given

[tex]Earnings = \$9.50[/tex] per hour

See attachment for complete question;

Solving (a): Complete the table

To complete the table, we simply multiply the earnings by the number of hours.

So, we have:

[tex]Hours = 2 \to Earnings = \$9.50 * 2 = \$19.00[/tex]

[tex]Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50[/tex]

[tex]Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00[/tex]

[tex]Hours = 5 \to Earnings = \$9.50 * 5 = \$47.50[/tex]

Solving (b): Earnings, if Megan works for 4 hours

In (a) above, we have:

[tex]Hours = 4 \to Earnings = \$9.50 * 4 = \$38.00[/tex]

This implies that Megan will earn $38.00

Solving (c): Hours to earn $28.50

In (a) above, we have:

[tex]Hours = 3 \to Earnings = \$9.50 * 3 = \$28.50[/tex]

This implies that Megan will work for 3 hours to earn $28.50

Answer:

Total cost =3over8 x 48 x0. 55=9.9

Answer:

$9.90

Step-by-step explanation:

First, we need to find the number of vanilla cupcakes.

The question tell us that 3/8 of the 48 cupcakes are Vanilla flavored, so we can start by dividing 48 by 8 to find what 1/8 of 48 is:

48/8 = 6

1/8 of 48 = 6

Now to find 3/8, we just need to multiply that number by 3:

6 x 3 = 18

3/8 of 48 = 18

So now we know that she bought 18 vanilla cupcakes.

Finally to find the price, we just need to multiply the price per cupcake by the number of cupcakes:

$0.55 per cupcake x 18 cupcakes = 0.55 x 18 = $9.90

The total cost of the vanilla cupcakes was $9.90

To write an equation for a parabola with the vertex and y-intercept, the equation of vertex form y=a(x-h)^2+k is used.

What is a parabola?

A parabola is an approximately U-shaped, mirror-symmetrical plane curve in mathematics. It corresponds to a number of seemingly unrelated mathematical descriptions, all of which can be shown to define the same curves.

Consider an example where vertex is (2,1) and y-intercept is (0,-3).

The equation of parabola needs to be deduced using these points.

The equation of a parabola in vertex form is -

y=a(x-h)^2+k

Here, a is a constant and (h ,k) are the coordinates of the vertex.

So, (h,k)=(2,1)

⇒y=a(x−2)^2+1

To obtain the value of a, substitute (0,−3) into the equation -

-3=4a+1

4a=-4

a=-1

⇒y=-1(x−2)^2+1

Now, distribute and simplify -

y=-1(x−2)^2+1

y=-(x^2-4x+4)+1

y=-x^2+4x-4+1

y=-x^2+4x-3

On, graphing this equation a parabola is obtained.

Therefore, to write an equation of parabola vertex form is used.

No, a TV with a 60 inch diagonal would not fit in an entertainment center that is 52 inches wide and 40 inches high.

Diagonal is a line connecting two or more points that are not in a straight line. It is used to describe the shape of a polygon and also used in mathematics to refer to lines, angles, and shapes. It can also refer to a line, or direction, that is not parallel or perpendicular to something else. In geometry, diagonal lines are used to divide shapes into equal parts, and are used in the construction of polygons. In linear algebra, diagonal lines are used to calculate the determinant of a matrix.

The diagonal measurement of a TV is the length of a line drawn between the opposite corners of the TV. For a 60 inch diagonal TV, the width of the TV would be around 52 inches and the height would be around 33 inches. As the entertainment center is only 40 inches high, the TV would not fit in it.

Answer:

c is the independent variable and f is the dependent variable

Step-by-step explanation:

Answer: x = 60

Step-by-step explanation:

the equation is a^2 + b^2 = c^2.

If you draw out the problem, you plug in the information into the formula, so it would be...

x^2 + 80^2 = 100^2.

80^2 = 6,400 and 100^2 = 10,000.

x^2 + 6,400 = 10,000.

You subtract 6,400 from itself and 10,000 and then you get...

x^2 = 3,600.

You square both of those and your final answer will be x = 60.
