Find: 1) the area of a circle of diamter 5 feet and radius 5/2 feet.
2) the area of a triangle with height 4 ft and base 6 ft.
Add these 2 results together: pi*(5/2)^2 + (1/2)(6)(4) ft
The trick here is to recognize basic shapes, find their areas separately and add the results.
Answer:
Therefore the volume of the gas is 32 cubic feet.
Step-by-step explanation:
Given that,
The volume of a gas varies directly with its temperature and inversely with the pressure.

V= Volume of the gas at constant mass
T= Temperature at constant mass
P= pressure at constant mass

.
Given that,
At constant mass, the volume of a certain gas is 15 cubic feet and a pressure of 40 pound per square inch at a temperature 300 k.
=15 cubic feet,
=40 pound per square inch and
= 300 K
,
=20 pound per square inch and
= 320k
.
Plugging all values


cubic feet
Therefore the volume of the gas is 32 cubic feet.
10.) DC
community property
11.) 13+x
community property
12.) 8x-12
distributive property
13.) (2+a)+b
14.) 4(2x+1)= 4+8x
For question 14 you can do 4×2=8x. Then do 4×1=4. It is equal. Just do distributive property for number 14 for 4(2x+1)
