The amount of the extra snow would a child need to take a snowball will be 636.71 cubic cm.
<h3>What is the volume of the sphere?</h3>
Let d be the diameter of the sphere.
Then the volume of the sphere will be
V = 1/6 πd³ cubic units
Then the amount of the extra snow would a child need to take a snowball with a diameter of 8 cm and increase its size to a snowball with a diameter of 12 cm will be
Amount of snow = 1/6 π x 12³ - 1/6 π x 8³
Amount of snow = 288 π - 85.33π
Amount of snow = 636.71 cubic cm

Yoko's fish tank has 17 liters of water in it. She plans to add 5 liters per minute until the tank has at least 57 liters. What are the possible numbers of minutes Yoko could add water?
Answer:
Minutes = 8 minutes
Step-by-step explanation:
Topic: Inequality
Given:
Available Size of water = 17 liters
Increment = 5 liters/minute
Size of water needed = At least 57 liters
Putting the above together, as have
17 + 5m > 57
where m represents total minutes and > represent at least
Solving the Inequality
5m > 57 - 17
5m > 40 ------ Divide through by 5
5m/5 > 40/5
m > 8
So, Yoko will need to add water for at least 8 minutes before she fills her tank to 57 liters.

the number of small cars rented is 6.
The number of large cars rented is 8.
Step-by-step explanation:
Step 1 :
Each small car can hold = 5 people
Each large car can hold = 8 people
Step 2 :
Number of small cars rented = x
Number of large cars rented = x + 2
Step 3 :
Altogether the total cars can hold 94 people.
Total people = 5 people (No. of small cars) + 8 people (No. of large cars)
94 = 5 (x) + 8 (x+2)
94 = 5x + 8x + 16
78 = 13x
x = 78/13 = 6
∴ Number of small cars, x = 6 small cars
Number of large cars, x+2 = 8 large cars.
