Answer:

1. 14476.46

2. 25333.8

3. 19142.66

Step-by-step explanation:

Ok lets take this slow...

First, read the directions; they want you to find how much water the barrles will hold, also meaning how much space is inside the barrel? This can be a hint to find for the area of the barrles.

The formula for a cyliner is: A=2πrh+2πr^2

You already have the information to solve the formula so all you have to do is plug the amounts in, whitch would look like this.

A= 2(3.14) (72) + 2(3.14) (24) ^2

    72 * 3.14           24 * 3.14

A= 2 (226.08)   +    2(75.36)^2

       452.16   +  2 (5679.1296)

       452.16   +     11358.2592

A≈ 14476.46

You would do the same for barel B and get: 25333.8

now subtract Barral A by Barral B to find the diffrence

144476.46 - 25333.8

The diffrent of barrle A and B is 19142.66

What is the solution to the equation 4x-6=10x-3
egoroff_w [7]

Answer:

x = -1/2

Step-by-step explanation:

4x - 6 = 10x - 3

  +6            +6

4x = 10x + 3

-10x   -10x

-6x = 3

/-6    /-6

x = -1/2

A 17.2 gallon gasoline tank is 1/2 full. How many gallons will it take to fill the tank?
love history [14]

Answer:

8.6

Step-by-step explanation:

We know that the tank is filled halfway, and it can hold 17.2 gallons, so we can just divide to figure out how much is half the tank (the amount we need to fill it)

17.2 / 2 = 8.6

We can check our work by multiplying

8.6 x 2 = 17.2

So it would take 8.6gal to fill it up. I hope this helps :)

How to solve this showing all work ! Also explain why they aren’t polynomials if you can :)
Lesechka [4]

Polynomials are linear combinations of positive integer powers. For example,

x^{100}+30x^2-\sqrt 2\,x+21

is a polynomial, but

-x^{-1}-4x^\pi+x^{3/2}

is not.

(In case you're unfamiliar with the term, a linear combination of two quantities is the sum of scaled versions of those quantities, e.g. a general linear combination of a and b is k_1a+k_2b, where k_1,k_2 are any numbers.)

8x^2-18\sqrt x+5x-3 is not a polynomial; the offending term is -18\sqrt x, or -18x^{1/2}.
