Hey there Kia!
![\left[\begin{array}{ccc}40/2=20 \ ; \ 19/2=9.5\end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D40%2F2%3D20%20%5C%20%3B%20%5C%2019%2F2%3D9.5%5Cend%7Barray%7D%5Cright%5D%20)
Your answer should look like the following.
![\left[\begin{array}{ccc} \frac{19}{20y}= \frac{9.5}{40y^3} \end{array}\right]](https://tex.z-dn.net/?f=%20%20%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%20%5Cfrac%7B19%7D%7B20y%7D%3D%20%5Cfrac%7B9.5%7D%7B40y%5E3%7D%20%20%5Cend%7Barray%7D%5Cright%5D%20)
Hope this helps you!
Answer:
When you are calculating the amount of mechanical energy used to exert force and move something, you are talking about work being done by a force at a distance. You can describe this in terms of foot-pounds. For example, you want to calculate the energy used to tighten a nut when using a wrench, or to lift a weight from the floor. Mechanical force takes place in time, so to describe the power requirement, you use foot-pounds per second.
Step-by-step explanation:
Temperature at mid-night
=235+(-485)
=-250 degrees, whatever the unit was (C,F, R, K).
3x=x+40
2x=40
x=20°
The two angles are equal, because they are vertically opposite. So you can equate them and get the answer.
Answer:
4000
Step-by-step explanation:
The number "4" is the base and the number 3 is the scientific notation "10^3"
x=4x10^3=4000
