Answer 1

Answer:

Answers:

C, D, E

Step-by-step explanation:

A rational number is a integer. It is also a terminating or repeating decimal.

A rational number can be written as a fraction of two integers.

Answer A is not correct because it's decimal never ends. It is also not repeating. A cannot be written as a fraction.

Answer B is not correct because the square root is not a whole number, or a perfect square. The square root has a non-terminating and non-repeating decimal, just like A. B cannot be written as a fraction.

Answer C is rational because it has a terminating decimal.

D and E are integers, which also can be written as fractions.

Out of the options given, C, D, and E have rational numbers, while all others do not.

The answers are C, D, and E.

You are paid $82.50 for 71212 hours of work. What is your rate of pay?

Answers

If you would like to know what is your rate of pay, you can calculate this using the following steps:

$82.50 ... 7.5 hours
$x = ? ... 1 hour

82.50 * 1 = 7.5 * x
82.50 = 7.5 * x /7.5
x = 82.50 / 7.5
x = $11

The correct result would be $11 per hour.

Two spherical chocolates are filled with a cream filling. The space inside one chocolate has a radius of 3 cm, and the other has a radius of 4.5 cm.How much more cream filling is in the larger chocolate than in the smaller chocolate? Use 3.14 to approximate pi and enter your answer to two decimal places.

Answers

so first find the volume of each then subtract

volume=4/3 times pi times r^3

rasius of smaller=3
4/3 times pi times 3^3
4/3 times pi timer 27
4/3 times 27 times pi
36 times pi
aprox pi=3.14
36 times 3.14
113.04=smaller

volume of smaller
4/3 times 3.14 times 4.5^3
4/3 times 3.14 times 91.125
381.51

subtract
381.51-113.04=268.47

the volume is 268..47 cm^3

4(1.5c+6)-2c=-9 I need a help my teacher doesn't help

Answers

4(1.5c+6)-2c=-9 so we distribute the 4 to 1.5 tand 6 and it will now be broken into this ==> 6c+24-2c=-9 ok now we most combine like terms so the we do 6c-2c= 4c so the problem is now 24-4c=-9 ok now i think we need to solve for c so we subtract 24 to -9 because it is negative it is now -33 so the problem is -4c=-33 divide by -4 and you will get your answer. I hope this helped and is correct.

Ok4(1.5c + 6) - 2c = -9First u do distributive property, and if u put arrows pointing from the number outside the parenthesis to each of the numbers inside u remember easier according to my math teacher. So 4 times 1.5c is 6c then 4 times 6 is 24Now the problem is written:6c + 24 - 2c = -9Now u add/subtract like terms so 6c - 2c is 4cSo 4c + 24 = -9Subtract 24 from both sides:4c = -33And now u just have to dived both sides by 4 to isolate the cAnd remember a negative times a positive is a negative (my math teacher taught us: bad things that happen to good people is a bad thing, to remember it)So the answer is:C = -8.25Now that it is corrected, I hope that helps :)
