a smallercircle passes through the center of, and is tanget to a larger cirlc the area of the smaller circle is 9 square units. What is teh area of the larger circle in square units
36 square units make up the larger circle's surface area.
We can use the fact that the smaller circle is tangent to the larger circle and passes through its center to find the area of the larger circle. Since the radius of the smaller circle is tangent to the larger circle, the radius of the larger circle is double the radius of the smaller circle.
Let's call the radius of the smaller circle "r" and the radius of the larger circle "R". We know that R = 2r.
We know that the area of a circle is given by the formula A = πr^2.
We know that the area of the smaller circle is 9 square units, we can use this formula to find the radius:
A = πr^2 => r^2 = 9/π => r = sqrt(9/π)
Now we can use the formula of the area of a circle with R-value to get the area of the larger circle:
A = πR^2 => A = π(2r)^2 => A = 4πr^2 => A = 4π(9/π) => A = 36
So the area of the larger circle is 36 square units

Step-by-step explanation:
Because their similar to each other, the corresponding angles are equal.
5y-3=82
5y=85
y=17
Angle J=angle M=z=180-82-65=33
3x-2=18.1
3x=20.1
x=6.7
Answer:
x = 6.7
y = 17
z = 33°
Step-by-step explanation:
To find x:
Because IJK≅LMN, you know that 3x-2 = 18.1
3x-2 = 18.1
Add 2 to both sides:
3x-2+2 = 18.1+2
3x = 20.1
Divide both sides by 3:
3x/3 = 20.1/3
x = 6.7
To find y:
5y-3 = 82
Add 3 to both sides:
5y-3+3 = 82+3
5y = 85
Divide both sides by 5:
5y/5 = 85/5
y = 17
To find z:
Because all triangles angles must add up to 180, find 180-82-65:
180-82-65 = 33 degrees
Because IJK≅LMN, z = 33 degrees

Step-by-step explanation:
The picture shows a shed. Find the length, AB, of the roof.
The length AB of the roof is 3.20 m.
What is the Pythagorean theorem.
The Pythagorean theorem is one that can be used to determine the value of the unknown side of a right triangle when given two of its sides.
The theorem states that;
/Hyp/^2 = /Adj/^2 + /Opp/^2
Considering the given picture of the shed, draw a perpendicular to B from a point C on parallel line A. So that the length of AB can be referred to as the hypotenuse of triangle ABC.
Now applying the Pythagorean theorem, we have;
/Hyp/^2 = /Adj/^2 + /Opp/^2
/AB/^2 = /2/^2 + /2.5/^2
= 4 + 6.25
/AB/^2 = 10.25
AB = (10.25)^ 1/2
AB = 3.20
Thus, the length of AB of the roof is 3.20 m.

P(1 + r/n)", where A is the balance (final amount), P is the principal
(starting amount), r is the interest rate expressed as a decimal, n is the number of times per
year that the interest is compounded, and t is the time in years.
Round your answer to the nearest cent.
$855.78
Step-by-step explanation:Interest, in this context, is the amount of money a saving account can earn over time.
Compound Interest Formula
There are 2 types of interest: simple and compound. For this question, we are going to use the compound interest formula. This formula is [tex]A = P(1+\frac{r}{n})^{nt}[/tex]. As stated in the question, A is the total balance, P is the principal, r is the interest rate, n is how often the interest is compounded, and t is time.
Variables
The values of these variables for this question are as follows:
P = 300.00The principal is the initial amount, and the question states that the account starts at 300 dollars.
r = 0.14The question says the interest rate is 14%, so we can convert this to the decimal 0.14.
n = 1If something is compounded annually, it is compounded once a year, so n must be 1.
t = 8If we want to find the balance after 8 years, we should set t equal to 8.
Solving for A
To find A, all we have to do is plug the variables into the formula.
[tex]A = 300(1+\frac{0.14}{1})^{1*8}[/tex]This can be rewritten as:
[tex]A=300(1.14)^8[/tex]Solve this to find that A ≈ 855.78. After 8 years, the balance will be $855.78.

How do you multiply FG?
FG cannot be multiplied because it is not a numerical value.
Multiplication is a mathematical operation that involves multiplying two numerical values together to produce a single numerical result. In order for multiplication to be possible, both values must be numerical values. FG is not a numerical value, which means that it cannot be multiplied. In order for FG to be multiplied, it would need to be replaced with a numerical value, such as a number or an expression that can be evaluated to a number. Without a numerical value, multiplication is not possible. Multiplying numerical values is done by taking the product of the two values, meaning that the result of the multiplication is the sum of each value multiplied by itself the number of times the other value is. For example, if you were to multiply 3 and 4, the result would be 12 because 3 multiplied by itself 4 times is 12, and 4 multiplied by itself 3 times is also 12. Without numerical values, this operation cannot be performed.

An ice cream factory makes 310 quarts of ice cream in 10 hours how many quarts could be made in 48 hours what was the ate per day
The factory can make 744 quarts of ice cream per day.
To find out how many quarts of ice cream could be made in 48 hours, we can use the principle of proportionality. Since the factory makes 310 quarts of ice cream in 10 hours, we can set up a proportion:
310 quarts / 10 hours = x quarts / 48 hours
To solve for x, we can cross multiply:
310 quarts * 48 hours = 10 hours * x quarts
x = (310 quarts * 48 hours) / 10 hours = 1480 quarts
So the factory could make 1480 quarts of ice cream in 48 hours.
To find the rate per day, we need to divide the number of quarts made per hour by the number of hours in a day. Since there are 24 hours in a day, we can calculate the rate per day as:
rate per day = (310 quarts / 10 hours) * 24 hours = (31 quarts/hour) * 24 hours = 744 quarts/day
So the factory can make 744 quarts of ice cream per day.
