Answer:

305.25

Step-by-step explanation:

18.5 for one floor, multiply by 15 to get the amount for 15 floors: 18.5*15 = 277.5 sheets

We need to add 10% for waste, meaning 277.5 plus the waste: 1.1*277.5 = 305.25

Use the number line to show<br> 2/3 divide 1/12 <br> What is the quotient
JulsSmile [24]

Answer:

8

Step-by-step explanation:

There is no number line given, so I will use the "keep change flip" method.

\frac{2}{3}\div\frac{1}{2}\\\rule{150}{0.5}\\  \frac{2}{3}\cdot\frac{12}{1}\\\\\frac{2\cdot12}{3\cdot1}\\\\\frac{24}{3}\\\\\boxed{8}

Hope this helps.

On a 50-question test, a student answered 5 questions incorrectly. What percent did the student answer correctly? A. 45% B. 90%
nadya68 [22]
Hey there,

Pretend that 50 = 100

And that 5 = 10.

I did a 100 test unit test, and I got 10% wrong.

If you think about this, the answer would be 90%

So, it's the same in this case,

50 in half of 100

5 is half of 10.

So . . .

This would mean that your correct answer would be 90% because 5 in this case is to be considered to be 10.

Your correct answer is  . . . . 

\boxed{\boxed{90 \ would \ be \ your \ correct \ answer }}

Hope this helps

The sum of 3 consecutive odd numbers is 183 whats the second number im this sentence​
Naddik [55]

Answer:

The second number is 61

Step-by-step explanation:

It's implied that the first integer is odd.

Since the consecutive intergers are odd, use an equation that looks like this:

(x+2) + (x+2) + (x+2) = 183 and simplify

*If you add 2 to an odd number, you get the next odd number. That's why I used 2*

3x + 6 = 183 → 3x = 177 → x = 59 which means the first integer is 59. The consecutive integers is 59, 61, 63.
