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?
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 .
An elephant walks with a speed of 12 steps a minute. How long was the elephant walking if she walked without stopping for 420 steps?
Answer:
35 minutes
Step-by-step explanation
420 (Total number of steps) / 12 (Number of steps per minute) = 35 (Total number of minutes walking)
I used the formula for speed here. Distance divided by speed equals time.
Answer:
7 minutes
Step-by-step explanation:
if you divide 420 by 60 (seconds in a minute) then you get 7

PLEASE HELP! (WILL GIVE BRAINLIEST FOR RIGHT ANSWER)
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!

The question is: There are 28 girls and 22 boys on a swim team what percent of the team is made up of boys? explain why pls.
Answer:
U first need to find out the total number of people
22+28
50
and since they are asking only for boys we need to put the number of boys on the numerator and the total number of people at the denominator
22/50
And now to make it into % we need to ALWAYS multiply the fraction by 100
22/50 x 100
44%
Hope it helps
Answer:
44 %
Step-by-step explanation:
okay so 100% is equal to the whole team or 50 swimmers
100% = 50 swimmers
to find out how much one swimmer is would be to divide the 100% by the total of swimmers.
100% / 50 swimmers
2% = 1 swimmer
so now that we know how much percent 1 swimmer is we will multiply 2% by 22, the number of boy swimmers.
2 x 22 = 44

find the area of the figure
A) 114cm
B)350cm
C)418cm
D)447cm
Answer:
409 is what I got.
Step-by-step explanation:
361 cm, as the square's area
and 48 as the area for the triangle.
Are you sure those are the answer choices because I'm getting 409.
Answer:
HEY!
THE TOTAL AREA OFTHE FIGURE = AREA OF SQUARE + AREA OF TRIANGLE
= [tex]a^{2}[/tex] +( [tex]\frac{1}{2}[/tex] x b x h)
where , [tex]a^{2}[/tex] = 19 x 19 = [tex]361 cm ^{2}[/tex]
and ( [tex]\frac{1}{2}[/tex] x b x h) = ( [tex]\frac{1}{2}[/tex] x 6 x 19) = ( [tex]\frac{1}{2}[/tex] x 114) = ( [tex]\frac{114}{2}[/tex] ) = [tex]57 cm^{2}[/tex] =
∴ [tex]361 cm ^{2}[/tex] + [tex]57cm^{2}[/tex] = [tex]418cm^{2}[/tex]
∴ 418 cm²
Hope it helped u!
