the time returning=x h,

the time going=(x-1) h,

s=t*v

s=(x-1)*50,

s=x*40,

(x-1)*50=x*40

x=5h,

s=t*v=5*50=250 miles

3/8 of a scholarship fund was 1500 find the full amount of the scholarship fund​
N76 [4]

Answer:

The full scholarship fund will be 4000

Step-by-step explanation:

When doing these types of problems I like to do this.

1500 ÷ 3 = 500 (We do this because you want to find out what 1/8 is)

Since 500 is 1/8 of the part, all you have to do is multiply 500 by 8

500 × 8 = 4000

Therefore, the formula for the volume of the sphere can be derived by writing an expression that represents the volume of
torisob [31]

Step-by-step explanation:

 The volume of a cone can be derived by writing an expression that represents the volume of one cone within the cylinder.

the expression for the volume of a cylinder is

volume-of-cylinder= \pi r^2h

the volume of a cone is a part of the volume of a cylinder

volume-of-cone= \frac{1}{3} \pi r^2h

Hence the volume of a cone can be derived by dividing the volume of a cylinder by 3

Use the equation 2,401 = 76 – 2x. What power of 7 is 2,401?
zaharov [31]
Comment
I'm going to take a guess at this and say what you meant is  2401 = 7^(6 - 2x)

Step One
Find out the power of 7 that will equal 2401. 
You could do it like this.
7^y = 2401 and just guess at some values.

y      7^y
1      7
2      49
3      7 * 7 * 7 = 343
4      7 * 7 * 7 * 7 = 2401  So the answer is 4

7^4 = 2401

Step 2 
Equate the powers.
2401 = 7^(6 - 2x)
7^4 = 7^ (6 - 2x)
4 = 6 - 2x  Subtract 6 from both sides.
4 - 6 = - 2x 
-2 = - 2x divide by - 2
-2/-2 = x
x = 1 <<<<<<<<<<<<<answer
