To find out how many servings in 4 1/2 cups if each serving is 1/2 cup you will
do the following
4 1/2 ÷ 1/2 or 4 1/2 x 2 (which is the same as the first one I wrote)
how many miles on 1 gallon?
Lauren: 320/10=32
Melissa:280/8=35
Who Drove farther?
32*40=1280
35*40=1400
Melissa can drive farther
This is the concept of trigonometry, the height of the ramp will be given by:
sin theta=[opposite]/[hypotenuse]
theta=30
opposite=x
hypotenuse=40 ft
hence;
sin 30=x/40
thus;
x=40sin30
x=20 ft
the ramp is 20 ft high
15ml to become more concentrated divide the amount
