Need help with these 3

Tamiku [17]

Answer:

1.) x = 110

$\frac{3}{22} =\frac{15}{x}$

So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110

$\frac{3 * 5}{22*5} =\frac{15}{110}$

2.) x = 72

$\frac{x}{16} =\frac{9}{2}$

For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72

$\frac{72}{16} =\frac{9}{2}$

3.) c = 24

$\frac{3}{5} =\frac{c}{40}$

For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24

$\frac{3*8}{5*8} =\frac{24}{40}$

A ball was thrown with an initial upward velocity of 80 ft./s from an initial height of 4 feet right in equation for H the heigh

ella [17]

That would be-
f(t)=80t+4
How I worked that out-
f(x)=mx+b
b= the y intercept which is 4
mx= your slope, which is 80t
f(t) is your height

What is the answer to the question -4•-10

Elis [28]

The answer is 40.
Because when you multiply 2 numbers, it becomes a positive number.(-4x10 or -2x3)
But if it were only one negative and positive then it would be negative because the answer is negative when you multiply by one negative number.
