When dividing these, the powers are subtracted form each other. 
We could split up the fraction into r's, s's, and t's.
r^-3 / r^2 = r^-5 [think of it as -3 -2]
s^5 / s = s^4
t^2 / t^-2 = t^4 [2 - - 2 = 4]

A negative power places it on the bottom of the fraction and the minus sign is removed from the power. 
So the answer is A: (s^4)(t^4)/r^5

zimovet [89]

<u>Answer:</u>

$165.60 overtime money only

$736 regular time only

added together (gross income)

$901.60

<u>Step-by-step explanation:</u>

  • 46hrs
  • 18.40 an hr
  • hrs <em>over</em> 40 = overtime= *1.5

To figure out if there is any overtime here, we <em>subtract</em>.

46-40= 6hrs of overtime

To figure out the amount of cash gained for regular time, we <em>multiply.</em>

40*18.40 = 736

----------------

We need to know how much money is paid per overtime hour.

18.40*1.5 = 27.60

To figure out the amount of cash gained during overtime, we <em>multiply.</em>

6*27.60 = 165.60

<em>add</em> for gross income (total earnings)

165.60+736 = 901.60

Answer:

For question 1 you can try dividing each of the value

For instance, you can divide 9 by 25 and see if you get a nice number

e.g. 1/8=0.125, numbers like these

For the second question, you can find the fraction by dividing 1000 starting with the decimal points

e.g 0.650, you would be plotting 650/1000 and you would simplify the fraction to the lowest value any value above the decimal point you can multiply by the denominator and add the nominator value to get your final answer.

What is the volume of a cylinder, in cubic centimeters, with a height of 8 centimeters
Arisa [49]

Answer:

1608.5 cm³

Step-by-step explanation:

Use the cylinder volume formula, V = \pir²h

If the diameter is 16 cm, then the radius is 8 cm.

Plug in the radius and height into the formula, and solve:

V = \pir²h

V = \pi(8)²(8)

V = \pi(64)(8)

V = 1608.5

So, to the nearest tenth, the volume of the cylinder is 1608.5 cm³
