Answer:

D) h = A/2πr - r

Step-by-step explanation:

A = 2πr(r+h)

A = 2πr² + 2πrh

2πrh = A - 2πr²

     h = (A-2πr²)/2πr

         =A/2πr - 2πr²/2πr

         =A/2πr - r

Fernando will divide 0.24 by 4 to help him solve a math problem. Which model below could represent this math problem
balandron [24]

Answer:

So the model should represent either \frac{6}{100} or\frac{3}{50} (its equivalent and simplified form.

Step-by-step explanation:

1) Originally the question wants to represent this quotient as tiles.

So,\frac{\frac{24}{100}}{4} =\frac{24}{100} *\frac{1}{4} =\frac{6}{100}=

We can still simplify it, but since we're dealing with 100 x 100 squares let's keep it this way

2) So the model should represent either \frac{6}{100} or\frac{3}{50} (its equivalent and simplified form.

Graph the line with slope 2 passing through the point (1, -3).
Pepsi [2]

Answer:

2x-5=y

I'm not sure how your graphing tool works so I'll give you five or so coordinates

(-1,-7)

(1,-3)

(0,-5)

(2,-1)

(-2,-9)

Step-by-step explanation:

You first need to write an equation that you can graph

Knowing that the slope is two we can write the following equation

2x+b=y

We also know that when x=1 y=-3

This gives us 2*1+b=-3

which means that 2+b=-3

subtract 2 from both sides to figure out the b=-3

This means that the line you have to graph is 2x-5=y

Choose the correct simplification of the expression a^7b^8/a^4b^4
Alex787 [66]
The answer is B: a^3b^4<span>

Proof:
Simplify the following:
(a^7 b^8)/(a^4 b^4)

Combine powers. (a^7 b^8)/(a^4 b^4) = a^(7 - 4) b^(8 - 4):
a^(7 - 4) b^(8 - 4)

7 - 4 = 3:
a^3 b^(8 - 4)

8 - 4 = 4:
Answer:  a^3 b^4

PS: I just wish that you put the equation down as it's intended i.e.
a^7b^8/a^4b^4 is not the same as (<span>a^7b^8)/(a^4b^4)</span>
