Answer:

Brianne gets 25.12 inches² of pancake.

Step-by-step explanation:

Assuming the pancake to be a circular shape.

If the pancake's distance from one side of the pancake to other side was 8 inches, then diameter of circle = 8 inches. It means radius = 4 inches.

Brianne cut her pancake in half to share with friend. It means Brianne gets half-circular shape. So we need to find area of half-circle.

Area of half-circle = (1/2)πr² = (1/2) x 3.14 x 4² = 1.57 x 16 = 25.12 inches².

Hence, Brianne gets 25.12 inches² of pancake.

D

Step-by-step explanation:

There's no solution because they are not touching each other. If they intersected at one point there would b one solution and if one is exactly on top of another there's infinity solutions which looks like only one line.

BC = 4x + 2 AB = 8x + 8 and AC = 22 Find BC
Scilla [17]

Answer:

BC = 6.8

Step-by-step explanation:

The distance from A to B, then from B to C, is the same distance as from A to C.

Thus,

AB + BC = AC

AB = 8x + 8

BC = 4x + 2

AC = 22

AB + BC = AC

(8x + 8) + (4x + 2) = 22

Expanding the parenthesis:

8x + 8 + 4x + 2 = 22

8x + 4x + 8 + 2 = 22

12x + 12 = 22

Subtracting 12 from both sides:

12x = 10

Dividing both sides by 12:

x = 10/12 = 1.2

x = 1.2

We're looking for BC. As we know,

BC = 4x + 2

Let's now put in x = 1.2 into this equation:

BC = 4x + 2

BC = 4 * 1.2 + 2

Since 4 * 1.2 is 4.8:

BC = 4.8 + 2

BC = 6.8

Answer: BC = 6.8

What is the value of x? Round to the nearest tenth.
kotykmax [81]

Answer:

27.5

Step-by-step explanation:

first you find what 30x30 is as A squared plus B squared is equal to C squared. your A is 12 and your C is 30.

so!

30x30 is 900

12x12 is 144

subtract 144 from 900 and you get 756. once you find the square root you get 27.49. then round up to 27.5
