Answer:
20
Step-by-step explanation:
2 in 529 is in the tens place - 10
So if 2 is in the tens place, we have 20 as the value of 2.
Answer:
constant of variation = 
Step-by-step explanation:
Given y varies directly as x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = 4
k = 
= 
=
To solve this problem you must apply the proccedure shown below:
<span>A) What is the surface area of the prism if the edge length of each connected cube is 5 centimeters?
- You must to substute e=5 cm into the formula given in the problem:
A=10e^2
A=10(5)^2
A=250 cm^2
</span><span>B) Arusha plans to build the prism and partially fill it with 150 cubic centimeters of sand. What fraction of the prism volume will be filled by the sand?
</span><span>
- First, you need to calculate the volume:
V=2e^3
V=2(5)^3
V=250 cm^3
250 cm^3----100
150 cm^3----x
x=150x100/250
x=60%
