Answer:
the answer is in the attached image below
Step-by-step explanation:
By similar triangles...
p/37=33/83
p=37(33)/83
p=1221/83 m
p≈14.711 m (to nearest thousandth of a meter, or nearest millimeter)
10 trees in 2 hours = 5 trees per hour
150 trees * 1 hour/ 5 trees = 30 hours
30 cars in 5 hours = 6 cars per hour
120 cars * 1 hour/6 cars = 20 hours
it will take 20 hours to wash 120 cars.
25 letters per minute * 5 minutes = 125 letters
15000 phones per hour
300000 phones * 1hour/15000 phones = 20 hours
375 ft^2/ 15 min = 25 ft^2/min
It will take 30 hours to plant 150 trees
Play A: y=15x+76
Play B: y=-x^2 +36x-4
set them equal:
15x+76=-x^2 +36x-4
80=-x^2+21x
x^2-21x+80=0
-> solve for x
for example with the quadratic equation formula or solving the square
factorized:
(x-16)(x-5)=0
so x1=5 and x2=16
insert them into y=15x+76
y1=151, y2=316
so (5,151) and (16,316) are days with equal attendance for both plays which is option C
