Lets suppose k is the constant of proportionality.
z = k * x / y
when x is 16 and y is 17, z has the value 11.294117647059
11.294117647059 = k * 16/17
Multiplying 17 on both sides
11.294117647059 * 17 = k * 16
192 = k * 16
Dividing 16 on both sides
192/16 = k
k = 12
Now when x= 22, and y= 26
z = k * x/y
z = 12 * 22 / 26
z = 10.1538461538 : Answer
Hope it will help :)
Answer:
17
Step-by-step explanation:
let x be the number of boxes to be shaded to make it 80%
x = 80% of total number
= 80/100 of 25
= 80/4
= 20
So 20 need to be shaded to fill 80%
Now, 13 of the grids are already shared so the amount of more squares that need to be shaded = 20-13
= 17 squares
There are 6 girls who wear glasses in the class, so the remaining must be the boys. 14-6=8 so there must be 8 boys who were glasses
Answer: he will need 355.68 centimeters³ of sand to fill half of the sandbox
Step-by-step explanation:
The formula for determining the volume of a rectangular prism is expressed as
Volume = length × base × height
It can also be expressed as
Volume = base area × height
The area of the base of the sandbox is 124.8 square centimeters, and it will have a height of 5.7 centimeters. This means that the volume of the sandbox is
124.8 × 5.7 = 711.36 centimeters³
Since Mr. Berger plans to fill the sandbox half full of sand, the volume of sand he will need to fill half of the sandbox is
711.36/2 = 355.68 centimeters³
