Mr. & Mrs. Bourrage's children all play different sports. They want to buy a
combination of track training sets, which each cost $150, basketball
training sets, which each cost $130, and cheerleading training sets, which
each cost $280. Let t represent the number of track sets, b represent the
number of basketball sets and c represent the number of cheerleading
sets. Which expression represents the total amount of money the
Bourrage's will spend based on the number of sports sets they buy?

150 + 130 + 280

150t + 130b + 280c

(150 + 130 + 280) (t + b + c)

t+b + c

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.

a is the right answer

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
