6 ft= 6x12in= 72 in.
8 ft= 8x12in= 96 in.
12ft=12x12in=144 in
25ft=25x12in=300 in
50ft=50x12in=600 in
72 in, 96 in, 96 in, 144 in, 300 in, 300 in, 600 in
Mean= (72+96+96+144+300+300+600)÷7
1608÷7 = 229.7 inches
Median=middle value in set = 144 inches
Mode= value(s) tha occur most often = 96 inches and 300 inches
Range=difference of largest and smallest values in set = 600-72= 528
Choice A
The formula for the surface area of a cylinder is:
2<span>π</span><span>r</span><span>h </span><span>+ </span><span>2</span><span>π</span><span>r^</span><span>2
If we substitute in the measurements that we know, you get:
2</span><span>
(3.5) (14) + 2</span><span>
(3.5)^2
If we simplify this expression, we get:
98</span><span>
+ 24.5</span><span>
If you simplify once more, you get
122.5</span><span>
or </span><span>≈ 384.85
Therefore, the surface area is 122.5</span>
or about 384.85<span>

Answer:
x=1 y=19
Step-by-step explanation:
Let's solve your system by elimination.
−9x+y=10; 10x−y=−9
−9x+y=10
10x−y=−9
Add these equations to eliminate y:
x=1
Then solve x=1 for x:
x=1
Now that we've found x let's plug it back in to solve for y.
Write down an original equation:
−9x+y=10
Substitute1forxin−9x+y=10:
(−9)(1)+y=10
y−9=10(Simplify both sides of the equation)
y−9+9=10+9(Add 9 to both sides)
y=19
Hope this helps, I don't really get the answer choices though....
