Answer:
2,600 students attend the school.
Step-by-step explanation:
We know that 24% of the total students are in twelfth grade, and 624 are in twelfth grade. This means 624 is 24% of the total. We can see that 100 / 24 = 4.167, and if we multiply 624 by 4.167, we get the total students attending the school, 2,600.
Answer:
The angle is 84 degrees
Step-by-step explanation:
Let's call the angle by 'x'.
the supplement of x is equal to 180-x, and the complement of x is equal to 90-x.
If the supplement is sixteen times the complement, we can write the following equation:
(180 - x) = 16 * (90 - x)
180 - x = 1440 - 16x
16x - x = 1440 - 180
15x = 1260
x = 84
The angle is 84 degrees.

Answer:
B. y² – 5y = 750
C. 750 – y(y – 5) = 0
E. (y + 25)(y – 30) = 0
I'm assuming the 2 in the second option is supposed to be an exponent.
Step-by-step explanation:
Length = y
Width = y-5
Length × Width = Area
Area = <u>y(y-5)</u> = 750
<u>Distribute.</u>
y²-5y=750 (B is correct)
<u>If you factor the equation above</u>
(y + 25)(y – 30) = 0 (E is correct)
Area = y(y-5) = 750
<u>Subtract y(y-5) from both sides.</u>
750-y(y-5) = 0 (C is correct)
