Quinn's mom went to the same middle school that Quinn is now attending. The current student population is 817 students. Since Quinn's mom attended, the school has experienced a
57% increase in population. About how many students were enrolled at the school when Quinn's mom attended?

Answers

Answer:

520

Step-by-step explanation:

Past number of pupils: p

Increase of 57% = 1.57

Present number of pupils = 817

p x 1.57 = 817

p = 817 divided by 1.57 = 520.382

rounded to the nearest whole number = 520 (this is why the question says "about" how many...)

57 x 817 = 46569

46569 divided by 100 = 465.69

817-465.69 = 351.31

Answer : 351

Explanation : 57 times 817 equals to 46569 and then you divided by 100 . Then it equals to 465.69 . To find out the how many more students were enrolled you have to subtract 465.69 from 817 and then you get 351.31 which you round to 351 .

Question one is last option between 8 and 9

Answer:

question 1: it is between 8 and 9. question 2: option B.

Step-by-step explanation:

1. since the closest value that IS a squarable number is 64, the square root of 64 is 8. because 66 is greater than 64, we can estimate that the square root of 66 is between 8 and 9.

2. to solve this, we can take the square root of the numbers to begin.

the square root of 25 is 5 (because 5x5=25)

the square root of 16 is 4

20 is actually not squarable, so we can estimate that it is a little greater 4.

the answer would be √16, √20, 4.85, √25

it would be option b.

hope this helps!! :))

PLEASE HELP! (WILL GIVE BRAINLIEST FOR RIGHT ANSWER)

Answers

Answer:

-41.29*  10^-7

Step-by-step explanation:

You would change the order of the numbers by multiplying -4.44 and 9.3 together and multiply 10^-7 and 10^0. Which would now look like this:

(-4.44* 9.3)* (10^-7* 10^0)

-4.44* 9.3= -41.292 and 10^-7* 10^0= 1* 10^-7. So now the equation would look like this:

-41.292* 10^-7

Then round -41.292 to 2 decimal places which would be -41.29.

-41.29*  10^-7

That's the answer. I hope this helps!
