Answer:

BQ = 16

QE = 8

Step-by-step explanation:

Centroid of a triangle divides the median in the ratio 2 : 1

Here, let BQ = 2x and QE = x

BQ + QE = BE

2x + x = 24

3x = 24

x = 24/3

x = 8

2x = 2*8 = 16

BQ = 16

QE = 8

Dominique can ice cupcakes twice as fast as Houston. When they work together, Dominique and Houston can ice a large order of cup
olganol [36]
This is a work problem. It can be solved as follows:

Houston = 1/x
Dominique = (1/2x)
Together = 1/5

Then, we add Houston and Dominique:

1/x + 1/2x = 1/5

Solve for x,

x = 2/15

Therefore, it would take 15/2 hours for Houston to ice by himself, the last option.
