Answer:
a. 3/5 liters per hour
b .06 hours
Step-by-step explanation:
Change 40 minutes to a fraction of an hour
40 minutes/ 60 minutes = 2/3 hour
It takes 1 2/3 hours to fill the container
Changing to an improper fraction
(3*1+2)/3 = 5/3 hours
We want liters per hour
1 liter per 5/3 hours
1 ÷ 5/3
Copy dot flip
1 * 3/5 = 3/5 liters per hour
Change 100 ml to liters
We know 1000 ml = 1 lt
100 ml * 1 lt/1000 ml = .1 lt
So 100 ml = .1 lts
.1 lt * 3/5 lt per hour
Changing the fraction to a decimal
.1 lt * .6 lt per hour
.06 hours
Answer: -2?
Step-by-step explanation:
The new dimensions of the sandbox in centimeter (cm) are:
length = 400 centimeters
Width = 300 centimeters
Height = 50 centimeters
Given:
Length = 4m
Width = 3m
Height = 0.5m
Convert meter to centimeter
1 meter = 100 centimeters
4m = 4 × 100 centimeters
= 400 centimeters
3m = 3 × 100 centimeters
= 300 centimeters
0.5m = 0.5 × 100 centimeters
= 50 centimeters
Therefore, the new dimensions of the sandbox in centimeter (cm) are
length = 400 centimeters
Width = 300 centimeters
Height = 50 centimeters
