A hobby shop has 4 times as many model airplanes as model helicopters. The total number of models is 35. How many model airplanes does the hobby shop have?
Answers
Answer 1
Answer:
let's call airplanes "a" and helicopters "h".
The total number of models is 35. This means that a+h=35
4 times as many model airplanes as model helicopters. This means a=4h.
we can substitute this into the previous equation:
4h+h=35
5h=35
dividing by 5:
h=7
so he has 7 helicopters and 4*7=28 airplanes

Ok so all you have to do to find sine is divide the length of one side by another side. So the "Hypotenuse" is the long one, 12, by the "Opposite" is the shortest side, 8. 12 divided by 8 is 1.5 and that as a fraction is 3/2. So your answer is D. 3/2.

This answer uses NMF, which you can find out about on my profile:
Preliminary work:
Following the BIDMAS order of operations, we can calculate part of it already, and that's the 2•4, which equals 8.
Therefore, the equation now reads:
8+x = y
x = 5:
8+5 = 13
13 ≠ 16
13 ≠ y
x = 4:
8+4 = 12
12 = 12
12 = y
Therefore, the pair is (4, 12)
