8 x 4 x 2 = 64
Therefore the volume of the pond is equal to 64m³
Answer:
x and y can help you show you the constant rate or the unit rate
Step-by-step explanation:
if you use a graph you can see that x mutipley my a certain number gets you y
Complementary angles add up to 90 (there should be a right angle in the diagram)
x+20+x+10 needs to equal 90 where x=30
Left angle is measured 30+20=50 degrees
Angle on the right is measured 30+10=40 degrees
60% or 3/5 of the tank will be filled in an hour.
The pump will fill 2/5 of the tank in 2/3 hours.
In order to find out how much of the tank will be filled in an hour, use direct proportion and assume portion of the tank that will be filled up in an hour is x.
<em>2/5 of tank : 2/3 hours </em>
<em>x of tank : 1 hour </em>
Cross multiply to get:
2/3x = 2/5
x = 2/5 ÷ 2/3
x = 2/5 x 3/2
= 0.6 of the tank
= 60%
= 3/5 of tank
In conclusion, 60% of the tank will be filled in an hour.
