Answer:
I believe the answer is ten.
Step-by-step explanation:
the line to CA is the same length as AE so you would double it to get ten for CD.
hope this helps!
If you would like to know which expression represents the amount of time Joe exercises, you can calculate this using the following steps:
Keith ... x hours a week
Troy ... three hours less than Keith: x - 3
Joe ... two times more than Troy: 2 * (x - 3)
The correct result would be D) 2 * (x - 3).
Answer:
Step-by-step explanation:
Use the equation
89 < 75 + 0.7*M Subtract 75 from both sides
89 - 75 < 0.7M Combine
14 < 0.7 M Divide both sides by 0.7
14/0.7 < M
20 < M
If M goes over 20 then the flat rate is cheaper.
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

=> <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>
<span>The Volume of a Cylinder = </span><span>π <span>• r² • height<span>
