Answer: The answer is 3 children.

Step-by-step explanation: 16:4 is considered 4:1 hence there were 4 of 16 children have been elementary school students. If you take a look at the ratio closer you may see it’s a division of 4, therefore 12 divided by 4 equals 3 children.

What is the slope of the line that passes through the points (2, 8) and (6, 12)?
zubka84 [21]
Yeah, where I live, to find the slope (or as we call it, the gradient), you just have to do the two y values subtracted from each other, over the two x values subtracted from each other. The important thing is to remember that if you subtract the first y value from the second (so, 12 - 8), you have to do the same thing for the x (6 - 2)

\frac{12-8}{6-2} = \frac{4}{4} = 1.

The slope is 1.

Hitting the baseball over the lights
Kisachek [45]

Answer:

Approximately 3.8 seconds

Step-by-step explanation:

H(x)=-16x^2+60x+4

We want to find when the ball hits the ground, or where the zeros are

0 =-16x^2+60x+4

Using the quadratic formula

-b ±sqrt(b^2 -4ac)

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

   2a

-60 ±sqrt(60^2 -4*-16*4)

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

   2(-16)

-60 ±sqrt(3600+256)

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

   -32

-60 ±sqrt(3856)

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

-32

We want the positive value for time

-60-62.09669879

---------------------------    

  -32
