Answer:
325 boys
Step-by-step explanation:
The ratio 5:7 represents 5+7=12 students. If we were to proportionalize this ratio to 780 students, we would multiply the ratio by 65/65 since 780/12=65.
Therefore, you have (5*65)/(7*65)=325/455 as your ratio. This means that there are 325 boys in the school
Class 1 =$177.90
Class 2 =$159
Class 1
24 tube of paint / $3.35 each
12 brushes/ $1.75 each
17 canvases/$4.50 each
Total cost of paint= $80.40
Total cost of brushes=$21
Total cost of canvases= $76.50
Total spent on class 1 = $177.90
Class 2
20 tubes of paint/$3.35 each
14 brushes/$1.75 each
15 canvases/ $4.50 each
Total cost of paint=$67
Total cost of brushes =$24.50
Total cost of canvases=$67.50
Total spent on class 2 = $159
Answer:
2
Step-by-step explanation:
greatest common factor means the greatest number we can divide by for each of the number and still get a whole number
14 and 22. they are both even so one factor is 2
if we check, 14 & 22 aren't both divisible by 3,4,5,6,7,8,9,10,11,12,13,14 so the gcf is 2

Answer:
56 square centimeters
Step-by-step explanation:
we know that
The formula for the area of a trapezoid is
![A=\frac{1}{2}[b_1+b_2]h](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5Bb_1%2Bb_2%5Dh)
we have
substitute in the formula
![A=\frac{1}{2}[6+10]7\\\\A=\frac{1}{2}[16]7\\\\A=(8)7=56\ cm^2](https://tex.z-dn.net/?f=A%3D%5Cfrac%7B1%7D%7B2%7D%5B6%2B10%5D7%5C%5C%5C%5CA%3D%5Cfrac%7B1%7D%7B2%7D%5B16%5D7%5C%5C%5C%5CA%3D%288%297%3D56%5C%20cm%5E2)
