Answer:
12.6
Step-by-step explanation:
To find the area of a cylinder, you find the area of the circular base and multiply it by the height. Remember that the area of a circle is pi*r^2. R, the radius, is 2. Putting this into a calculator and rounding to the nearest tenth, you get 12.6. Now that we have the circle, we multiply by the height. Since the height is 1, we have our answer of 12.6.
Answer:
<h2><em><u>n</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>7</u></em></h2>
Step-by-step explanation:
4(n-1)+2 = -23 +7n
=> 4n - 4 + 2 = - 23 + 7n
=> 23 - 4 + 2 = 7n - 4n
=> 21 = 3n
![= > n = \frac{21}{3}](https://tex.z-dn.net/?f=%20%3D%20%20%3E%20n%20%3D%20%20%5Cfrac%7B21%7D%7B3%7D%20)
=> <em><u>n</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>7</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
Answer: The total cost is
assuming the cost for 1 adult is
and the cost for 1 child is ![\$2](https://tex.z-dn.net/?f=%5C%242)
Step-by-step explanation:
Assuming the cost for 1 adult is
and the cost for 1 child is
:
and ![c=\$2](https://tex.z-dn.net/?f=c%3D%5C%242)
Then the expression that gives the total cost
is solved as:
![10(\$5)+6(\$2)=\$62](https://tex.z-dn.net/?f=10%28%5C%245%29%2B6%28%5C%242%29%3D%5C%2462)
The answer is 36 I'm pretty sure
to graph a LINEar equation, since it's just a straight line, recall, to draw a straight line all you need is two points.
so we can just pick two random "x" values, hmmmmm say x = 0, what's "y"?
y = 7(0)-7 => y = -7....................................... so that gives us the point (0, -7)
hmmm x = 2, what is "y"?
y = 7(2) - 7 => y = 14-7 => y = 7................. so we get the point (2, 7).
then just plot those, and run a line through them.
