210 = 4/5 (This means that 4 out of five people (210 people) are a teenager)
Then you divide 210 by the numerator to get 1/5 people:
210 / 4 = 52.5
Then you can multiply the 1/5 people (52.5) by 5 to get 5/5:
52.5 * 5 = 262.5 (rounded to 262)
Thus the maximum amount of teenagers in Geotown is 262.
Hope this helps! :)
Answer:
Third option is correct.
Step-by-step explanation:
The given model is
![h(t)=-16t^2-30t+124](https://tex.z-dn.net/?f=h%28t%29%3D-16t%5E2-30t%2B124)
Where, h(t) is heigth of rock after time t (in seconds).
The initial height of rock is 124 ft.
The leading coefficient is negative. It means it is a downward parabola.
First we have to the x-intercepts of the function.
![0=-16t^2-30t+124](https://tex.z-dn.net/?f=0%3D-16t%5E2-30t%2B124)
Using quadratic formula, we get
![t=\frac{-(-30)\pm \sqrt{(-30)^2-4(124)(-16)}}{2(-16)}](https://tex.z-dn.net/?f=t%3D%5Cfrac%7B-%28-30%29%5Cpm%20%5Csqrt%7B%28-30%29%5E2-4%28124%29%28-16%29%7D%7D%7B2%28-16%29%7D)
and ![t=2](https://tex.z-dn.net/?f=t%3D2)
It means rock remains in the air between
.
The value of t can not be negative, therefore rock remains in the air between
.
Third option is correct.
Answer:
2x-3y=6
X will = 0 Y will = 0
Therefore the x intercept would be 2 and the y intercept would be 6.
This is what i put lol im not sure, i have an A plus in math so this wont hurt it.
Answer:
x = 10
Step-by-step explanation:
Every triangle has 180o. Just add the three angles together.
8x + 5 + 3x + 25 + 4x = 180 Combine the like terms.
15x + 30 = 180 Subtract 30 from both sides
15x = 180 - 30 Combine
15x = 150 Divide by 15
x = 150/15
x = 10
