Your answer is 2,200 pupils.
If 990 is equal to 45% of the total amount of pupils, then to find 1% we can divide both 45 and 990 by 45.
990 ÷ 45 = 22, which is 1%, so then we multiply 22 by 100 to get 100% of the pupils, which gives us 2,200.
I hope this helps!
Answer: 0.875
Step-by-step explanation:
30 - 16 = 14
14/16 = 0.875
The answer should be true
Add the ratios together and divide them by 132. then times the number by the answer you get.
3+3+5=11
132÷11=12
12×3=36
12×3=36
12×5=60
so: 36:36:60
Answer:
y=4x+23
Step-by-step explanation:
<u>Convert given equation into slope-intercept form:</u>
12x-3y=10
4x-y=10/3
-y=10/3-4x
y=-10/3+4x
y=4x-10/3
Because the new equation must be parallel to the old equation, the slope stays the same, but the y-intercept changes based on the point that the new equation should pass through:
y=4x+b
3=4(-5)+b
3=-20+b
23=b
This means the slope-intercept form of the equation of the line that passes through (-5,3) and is parallel to 12x-3y=10 is y=4x+23
