Answer:

36π in^2

Step-by-step explanation:

The formula for calculating area of a circle is π×r^2

since the radius is given as 6

π × 6^2 = 36π in^2

Answer:

The answer is 3rd point, 36π in²

Step-by-step explanation:

Given that thr formula of area of circle is A = π×radius². Then you can substitute the following values into the formula:

radius = 6 in

A = π × 6²

= 36π in²

If TSP and PSW are supplementary, and TSP is two times as large as mPSW, what is mTSP?

Burka [1]

Answer:

$\huge\boxed{120 \textdegree}$

Step-by-step explanation:

In order to solve for m∠TSP, we can use basic angle relationships and equations.

Let’s assume m∠PSW is $x$ °

We know that if two angles are supplementary, their angle lengths will add to 180°.

We also know that m∠TSP is twice as large as PSW. Since PSW is represented as x°, TSP will be 2x°.

We can add these two angles together and get 180°. Then you can solve for x (PSW)

$x+2x=180$
$3x=180$
$x=60$

So we know that x (PSW) is 60°. However, the question asks for the measure of TSP. We know that TSP is twice as large as PSW, so we can multiply PSW (60) by 2.

$60 \cdot 2 = 120$

So m∠TSP is 120°.

Given the function f(x)=-2x+x, find f(7)

Allisa [31]

Answer:

f(7)= -7

Step-by-step explanation:

f(x)= -2x+x f(7) which basically means x=7

= -2(7)+7

= -14+7

f(7) = -7

Hope this helps :)

8 slices of pizza and 5 sodas cost $36.50. 4 Slices of pizza and 10 sodas cost $37. How much does a slice of pizza cost? How muc

LiRa [457]

Step-by-step explanation: If we use the variable <em>p </em>to represent our pizzas and <em>s</em> to represent our sodas, if our first equation states than 8 slices of pizza and 5 sodas cost $36.50, that's 8p + 5s = 3650.

Notice that I expressed cost in terms of cents so

that we can avoid having to deal with decimals.

In our second equation, 4 slices of pizza and

10 sodas cost $37, that's 4p + 10s = 3700.

Now let's rewrite our two equations on top of one another.

8p + 5s = 3650

4p + 10s = 3700

To solve this system of equations, I would use addition.

I would multiply the bottom equation by -2

to create a situation where our p's will cancel.

When we do that, we get -8p - 20s = -7400.

Now rewrite the equations once again ~

8p + 5s = 3650

-8p - 20s = -7400

Now add the equations together.

So we have -15s = -3,750.

Divide both sides by -15 and s = 250.

Remember that I expressed cost in terms of cents so

since s = 250, it really means that a soda is $2.50.

Now just plug an s back in for the s in one equation.

When we do this, we find that p = 300.

So a pizza is $3.00

A recipe for making popcorn requires 2 tablespoons of butter for every 1/3 cup of popcorn kernels. At this rate, how much butter

PtichkaEL [24]

Answer:

12 tablespoons of butter

Step-by-step explanation:

Create a proportion:

$\frac{2}{1/3}$ = $\frac{x}{2}$

Cross multiply:

1/3x = 4

x = 12

= 12 tablespoons of butter
