Colfax:
Add the ratio numbers together:
5 + 4 = 9
Divide total students by that:
270 / 9 = 30
Multiply each ratio by 30:
Boys = 30 *5 = 150
Girls = 30 * 4 = 120
Do the same for Winthrop:
4 +5 = 9
180 /9 = 20
Boys = 20 * 4 = 80
Girls = 20 * 5 = 100
Total students = 270 + 180 = 450
Total Girls = 120 + 100 = 220
Fraction that are girls = 220 / 450 which reduces to 22/45
Answer:
Step-by-step explanation:
It's B.
So the equation is x > -25. In word form, "The solution to this equation is greater than -25."
B begins at -25, and has a thick arrow pointing in the positive direction.
Answer:
4.75
Step-by-step explanation:
19 goes into 4 4 times, so we are left with 4 3/4. 3/4 is 0.75, so we have 4.75 as our answer.
I don't know if this is what your looking for but 113% = 113/100 can be 1 13/100.
The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:

When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes

Rewrite as:

Divide both sides by 16t

Hence, it takes the rocket 25 seconds to hit the ground
