Suppose water flows from a shower at a rate of 0.56 cubic feet per minute. Do you use more water by taking a 12 minute shower or by filling a bathtub with a 0.62 cubic yards of water, and by how much?

you use more water by filling the bathtub with 0.62 cubic yards.By 10.02cubic feet.

Step-by-step explanation:

0.56 cubic feet for 12 mins=

0.56*12=6.72 cubic feet

but 1cubic yard=27cubic feet

hence,27*0.6 cubic yards

=16.74cubic feet

by subtraction,

(16.74-6.72)cubic feet

=10.02cubic feet

f(x) = - 2/3x + 5; f(5/2)

substitute 5/2 in for x:

f(5/2) = -2/3(5/2) + 5

simplify the right side:

f(5/2) = -5/3 + 5

f(5/2) = 10/3

answer:

f(5/2) = 10/3

i hope this you!

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
