Answer:
A. 70
Step-by-step explanation:
a triangle has a sum of 180 degrees so you have to add 75 and 35 and you will get 110 and then you subtract 110 for 180 and you get 70
Answer:
Step-by-step explanation:
<u>Given:</u>
- Total certificates = 500
- Math = m
- Science = s
<u>Equations </u>
<u>Girls who won certificates:</u>
- 2/3m = 50 + 3/2*1/2s
- 2/3m = 50 + 3/4s
<u>Multiply both sides by 12 to clear fractions</u>
<u>Substitute s</u>
- 8m = 600 + 9(500 - m)
- 8m = 600 + 4500 - 9m
- 17m = 5100
- m = 5100/17
- m =300
<u>Girls who won math:</u>
The Angles are adjacent and since they are both on a straight line it means that the sum of the angle is 180 degrees, so we get the equations:
So x = 26.
Hope that helps!
Revenue = price * number of backpacks
number of backpacks = -2p + 50
p = 9 ; -2(9) + 50 = -18 + 50 = 32
revenue = 9 * 32 = 288
p = 12 ; -2(12) + 50 = -24 + 50 = 26
revenue = 12 * 26 = 312
<u>p = 12.50 ; -2(12.50) + 50 = -25 + 50 = 25</u>
<u>revenue = 12.50 * 25 = 312.50</u> GIVES THE MAXIMUM REVENUE
p = 15 ; -2(15) + 50 = -30 + 50 = 20
revenue = 15 * 20 = 300
