Answer:
Building's actual height 32 meters
Building's shadow height 20 meters
Person's shadow height 1.2 meters
Person's actual height = ?
Find the person's actual height:
This is a proportion problem.
Actual height to shadow height
Building = Person
32 : 20 = x : 1.2
32 * 1.2 = 20 * x
38.4 = 20x
38.4/20 = 20x/20
1.92 = x
The person's actual height is 1.92 meters long.
32 : 20 = 1.92 : 1.2
32/20 = 1.60
1.92/1.2 = 1.60
Step-by-step explanation:
Answer:
The answer is <em>C</em> or 30%
I divided 21 by 70 (21/70) to get 0.3 or 30% of 100...

The complete question in the attached figure
let
x-------> t<span>he number of ounces of pineapple juice
y------> </span><span>the number of ounces of grapefruit juice
we know that
x+y=32
x=2y+5-----> x-5=2y
using a graph tool
see the attached figure N 2
the solution is
x=23 ounces (</span>pineapple juice)<span>
y=9 ounces (</span>grapefruit juice)<span>
therefore
the answer is the option a</span>
Answer:
x=-1
Step-by-step explanation:
-8(-8x-6)=-6x-22
Distribute
64x +48 = -6x -22
Add 6x to each side
64x+6x +48 = -6x+6x -22
70x +48 = -22
Subtract 48 from each side
70x +48-48 = -22-48
70x = -70
Divide by 70
70x/70 = -70/70
x=-1
