So,

The diameter is 8.6ft.  We need to convert to radius.

2 radius = 1 diameter

8.6/2 = 4.3 ft.

\pi r{2}

\pi  4.3^{2}

\pi 18.49

3.14(18.49)

58.0586ft.²

Divide by 2 (semi-circle)
29.0293ft.²

The length of a rectangle is four times the width. The perimeter of the rectangle is 45 inches. Write a system of equations that
Nady [450]

Step-by-step explanation:

2×length + 2×width = 45

length = 4×width

now, we are using the second equation (a variable identity) in the first equation

2×4×width + 2×width = 45

8×width + 2×width = 45

10×width = 45

width = 45/10 = 4.5 in

length = 4×width = 4×4.5 = 18 in

the area of the rectangle is

length × width = 18 × 4.5 = 81 in²

Lupe can ride her bike at a rate of 20 mph when there is no wind. On one particular day, she rode 2 miles against the wind and
WARRIOR [948]

Hello there! Your answer should be 4 mph. Reasoning:

2 = (20 - x) * t 

3 = (20 + x ) * t 

Time is the same for both equations. Solve for T.

2/(20-x) = 3/(20+x)

the answer is 4 mph.

Please tell me if I was right!
