Answer:3/4 miles per hour
Step-by-step explanation:
Simplify the fraction 20/15 to get 3/4 per hour or 0.75 miles per hour
The first thing we must do in this case is to rewrite the length of the first tape.
We have then:
4/8 = 2/4 = 1/2 = 3/6 yard
Therefore, since the tapes have the same length, the following measure is NOT possible:
4/6 yard
Answer:
A. 4/6 yard
9/10 is the answer. Basic elementary math
Let f be the height of the fir trees
Let p be the height of the pine trees
We know from the problem that
f + p = 21 and 4f = 24 + p
rearrange the 2nd equation to get p = 4f - 24 and substitute into the other equation
so...
f + 4f - 24 = 21
5f - 24 = 21
5f = 45
f = 9 - height of the fir tree
substitute back into the 1st equation
9 + p = 21
p = 12 - height of the pine tree
By doing (125^2/1254/3) i get 4.15 every time i try to do it a different way, but if you do 125^(2/3) i get 25 for the answer.
answer: D) 25
hope this helped :)
