What is the surface area of a cube? well the cube has 6 sides all squares (lenght+width)the volume of a cube is just the areas of a side the hieght (or lenght or width since they are equal) so given that the cubes surface area is 3750 sq ft you should be able to find the area of one side then take the square root to find the lenght of one lenght at one edge and use that to find he volume and the answer is 15625 cubic feet

Can the exponent in the denominator be subtracted from the exponent in the numerator when the based are different? Explain
Vanyuwa [196]

Answer:

No, Sorry.

Step-by-step explanation:

Since the bases are different, you'll have to change them even if they have a exponent or not. If you dunno how to make the denominators the same, just multiply the two by eachother.

Example) 1/2 - 3/4

\frac{1}{2}  -  \frac{3}{4}

Multiply 2 and 4 together, and then multiply the 4 to the one also. Multiply 2 to four and also to the 3.

\frac{4}{8}  -  \frac{6}{8}

The subtract from there.

\frac{ - 2}{8}

and then Reduce (if needed.)

\frac{ - 1}{4}

(9,-1); m=4/3 write an equation in point slope form for the line through the given point with the given slope
madreJ [45]
For this problem you are going to need to know the point-slope equation which is: 
y-y₁=m(x-x₁)

Now, m=slope and the x and y values are given to us already, so now we just plug our variables into the formula.

It should look like this: y+1= \frac{4}{3}(x-9)
Since all they are asking for is for you to put it into a formula this will be your answer.

Point B lies between points A and C on AC. Let x
Alex_Xolod [135]

Set up the following equation for this segment:

x is segment AB's length, and 3x is segment BC's length. 20 is segment AC's length.

Combine like terms:

Divide both sides by 4 to get x by itself:

x will equal 5.

Plug this value into the values for both segments:

Segment AB:

Segment AB is 5 inches long.

Segment BC:

Segment BC is 15 inches long.

if the diameter of a cone is 16cm and the height is 15cm what is the volume? I've tried the formula v=1/3*3.14*r^2*h but the ans
Alisiya [41]

Answer:

V= volume of cone A=Ah A= πr2

A= area of base 3

H= height

V= (3.1416)(16)(15) 3.1416x16x15= 753.9

3

V= 753.9 753.9÷3= 251.3 cu. in

3

Volume of the cone is 251.3 cu. in

I hope this helps you. Good luck!
