Answer:
32 yd²
Step-by-step explanation:
Use the area formula with the given dimensions.
A = 1/2(b1 +b2)h . . . . . base lengths b1, b2; height h
A = 1/2(2 +6)8 = 1/2(8)(8) = 32 . . . . square yards
The area of the trapezoid is 32 square yards.
Write and solve an equation of ratios:
15 min 3 racks
---------- = -------------
x 36 racks
Solving this for x: 3x = (15)(36) => x = 180 minutes.
convert this into hours: 180 min 1 hr
------------ * -------------- = 3 hrs (answer)
1 60 min
30 + 1x = 18 + 5x
subtract 18 from both sides
30 - 18 + 1x = 18 - 18 + 5x
12 + 1x = 5x
subtract 1x from both sides
12 + 1x - 1x = 5x - 1x
12 = 4x
To clear the multiplication by 4, divide both sides by 4
12/4 = 4x/4
3 = x

They will each have 33 CD's
Answer: 76.35in²
Step-by-step explanation:
Circumference of a circle = 2πr or πd , while area is πr².
To find the area we must first of all find the radius if the circle using any of the formula above.we then equate 31 to 2πr and then solve for r.
31 = 2πr , where π = 3.142 or 22/7
r = 31/2 x 3.142
= 31 /6.284
= 4.93in
To find the area, substitute for r in the formula above,
Area = πr²
= 3.142 x 4.93²
= 3.142 x 24.30
= 76.35in².
