Answer:
35 Men were in the dance recital
Step-by-step explanation:
The ratio from MEN to WOMEN is 5:7
49 female performers is 7
49/7= 7 performers
to find how many men, you would do 7*5
7*5= 35
35 Men were in the dance recital
Hope this helps and made sense!
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
Answer:
w= -9 :)
Step-by-step explanation:
See, pls, the offered decision:
1. this ratio has another form: 2x/3x/4x;
2. the difference between the largest and the smallest is 4x-2x=10.
Then x=5, and the sequence of numbers is 10/15/20, where 15 is the middle number.
Answer: 15.
