Let's get the slope of this line, making a triangle between points (0, 2.5) and (15, 7.5)


tg x = oc/ac

tg x = 5/15

tg x = 1/3


So, m = 1/3


(y - yo) = 1/3.(x - xo)


Now just put a point


(y - 2.5) = 1/3.(x - 0)

y - 5/2 = 1x/3


For 40 cars:


40 - 5/2 = x/3

75/2 = x/3

112,5 = x


Making an approximation we have 115 as ans, alt B.

Can the formula F=ma be a direct variation equation? If so, which variable would have to be held constant?
ANEK [815]
Yes it can be a direct variation.  it follows the form y = kx
The only variable that cannot be held constant is F, but we can hold the mass constant and vary the acceleration OR we can hold the acceleration constant and vary the mass.  Either one would work, but the easiest would be to vary the mass and hold the acceleration constant since we are all pulled by the same action gravity

A book sold 33,200 copies in its first month. Suppose this represents 7.4% of the number of copies sold to date. How many copies
Marta_Voda [28]

Answer: 448648

Step-by-step explanation:

33,200 copies represent 7.4% of the total amount

-----------------------------------------------------

#1  33,200 ÷ 7.4%

- this is because how we get 33,200 by calculation is use the total amount and times 7.4% to get 33,200. So we are just working backwards. Since it was times before, then we divide after.

 33,200÷7.4%

=33,200÷0.074

≈448648 (you can't round up when the real amount is less the exact amount)
