Answer:
25
Step-by-step explanation:
If 5/8 are boys then
1 - 5/8 = girls
3/8 = girls
3/8 of the total are girls
Let x = total
3/8 ( x) = 15
8/3 * 3/8 * x = 15 * 8/3
x = 40
There are 40 total students
5/8 are boys
5/8 * 40
25 are boys
To find the unit rate you do distance ÷ time
16 miles ÷ 2 hours = 18
To find the time you do distance ÷ unit rate
20 miles ÷ 18 = 1.1
To find the distance you do time • unit rate
3 hours • 18 = 54
2) 1.1, 54, 1.8, 90, 27
3) 48, 3, 30, 2, 1
Answer:
32 ft^2
Step-by-step explanation:
Area of a trapezoid: (b1 + b2 /2 )h
a= (3+5/2)2
8/2= 4
4*2= 8
8 is the area of a trapezoid, to find area of 4 trapezoid multiply by 4
4*8= 32ft
