Answer:
Step-by-step explanation:
8)
around the tank = 12 * circumference
circumference = d
c = 30
c = 94.2477796
area around tank = 12 * 94.2477796 = 1130.973355
now top of tank
area of a circle = 

*
= 706.858347
add the two surface areas together for the total
706.858347 + 1130.973355 = 1837.832
total surface area = 1837.8 
10) all I see in the picture is a cylinder, but it's saying "composite" shape so I know there is probably more, but the cylinder is
*
* 10 = 282.7 
What you want to do is get x alone. So, divide both sides by -1/2 so x is alone. -12 divided by -1/2 is 24. Since this is an inequality you have to flip over your inequality sign when multiplying or dividing by a negative so your answer is now x>24
Answer:
x = 12
Step-by-step explanation:
The product of the length of the secant segment and its external part equals the square of the length of the tangent segment.
3*x = 6^2
3x = 36
Divide each side by 3
3x/3 = 36/3
x = 12
9 feet
Step-by-step explanation:
The table cloth would be 9 feet in length
20 ÷ 5 = 4
So there are 4 sets of 5 shirts. If there are 3 striped shirts per 5 then
3 x 4 = 12 striped shirts
Hope it helps!
