Answer:
x = 15
x = 15
The answers should be the same because the triangles are similar. The ratio of the sides are in the same proportion.
Step-by-step explanation:
a. x 12
------- = --------------
20 16
using cross products
x*16 = 20 * 12
16x = 240
divide by 16 on each side
16x/16 = 240/16
x = 15
b x 6
------- = --------------
20 8
using cross products
x * 8 = 6 * 20
8x = 120
divide each side by 8
8x/8 = 120/8
x = 15
c. The answers should be the same because the triangles are similar. The ratio of the sides are in the same proportion.
Let area to be painted = X m²
Rate for Allen = X / 16 m² / h
Rate for Brianne = X / 18 m² / h
Combined rate
X/16 + X/18 m² / h
[ 18X + 16X ] / 144 m² / h
34 X / 144 m² / h
time = X / [ 34 X / 144 ] h
time = 144 / 34 h
time = 4 h 14 min
