Answer:

y=4

Step-by-step explanation:

42/30 = (y+24)/20

Cross multiplying,

30*(y+24) = 42*20

30y + 30*24 = 840

30y + 720 = 840

Subtract 720,

30y + 720 - 720 = 840 - 720

30y = 120

Divide by 30,

y = 120/30 = 4

Richard s kitchen floor measures 22 ft by 16ft. He plans on laying title down and each tile piece measures 16 inches by 16 inche
olya-2409 [2.1K]
We calculate the floor area of the kitchen:
 A = (22) * (16)
 A = 352 feet ^ 2
 We consider the following conversion:
 1 foot = 12 inches.
 Applying the conversion we have:
 A = 352 * (12/1) ^ 2
 A = 50688 in ^ 2
 We calculate the area of each tile:
 A = (16) * (16)
 A = 256 in ^ 2
 Then, the number of tiles is given by:
 N = (50688) / (256)
 N = 198
 Answer:
 He
 needs to buy 198 tiles

Find the volume of the solid obtained by rotating the region bounded by the given curves about the specified axis. y = 64x−8x^2,
Mandarinka [93]
We need to get the limits first. When y = 0
0 = 64x - 8x^2
x = 0 and x = 8
The volume is
V = ∫ y dx from 0 to 8
V = ∫ (64x - 8x^2) dx from 0 to 8
V = 32x^2 - 8x^3/3 from 0 to 8
V = 682.67<span />
