How do I solve this please? Can SOMEONE please help me this and the ones Iposted on my page.
vagabundo [1.1K]

Answer: \dfrac{15}{64}

Step-by-step explanation:

Given

Inside radius of figure r_1=\frac{14}{2}=7\ ft

Outside radius of figure r_2=\frac{16}{2}=8\ ft

Area of outside region is A_1=\pi (8^2)

Area of inside region A_2=\pi (7)^2

Area of shaded region A_1-A_2

Probability that point lies inside the shaded region is

\Rightarrow P=\dfrac{A_1-A_2}{A_1}\\\\\Rightarrow P=\dfrac{\pi (8^2-7^2)}{\pi 8^2}\\\\\Rightarrow P=\dfrac{64-49}{64}\\\\\Rightarrow P=\dfrac{15}{64}

Luke bought 256 ounces of strawberries. he divided them evenly between 8 different pies.
pychu [463]

Answer:

2 pounds.

Step-by-step explanation:

We have been given that Luke bought 256 ounces of strawberries. He divided them evenly between 8 different pies. We are asked to find the pounds of strawberries that Luke put on each pie.

First of all, we will convert 256 ounces into pounds.

We know that 1 pound equals 16 ounces. To convert 256 ounces into pounds, we need to divide 256 by 16.

256 ounces=\frac{256}{16} pounds=16 pounds

Now we will divide 16 pounds by 8 to find number of strawberries put on each pie.

Pounds of strawberries on each pie=\frac{16}{8}

Pounds of strawberries on each pie=2

Therefore, Luke put 2 pounds strawberries on each pie.

Solve for x, and angle c
patriot [66]

9514 1404 393

Answer:

  x = 12.75

  ∠C = 51.75°

Step-by-step explanation:

The two marked angles are complementary, so ...

  (5x -12) +(3x) = 90

  8x = 102

  x = 102/8

  x = 12.75

__

C = (5x -12)° = (5(12.75) -12)°

  ∠C = 51.75°

__

<em>Check</em>

E = 3x = 38.25, then C+E = 51.75 +38.25 = 90 . . . . as it should

What is the y intercept of the function f(x)=2•3^x
kykrilka [37]

Answer:

\boxed{Option \ A}

Step-by-step explanation:

f(x) = 2*3^x

y intercept is when x = 0

So, Putting x = 0 in the above function

=> f(0) = 2*3^0

=> f(0) = 2*1

=> f(0) = 2

So, y-intercept is (0,2)
