Answer:
35
Step-by-step explanation:
10/12 of an hour/60 minutes = 50 minutes so they spent that amount of time doing daily exercises
1/4 of an hour/60 minutes = 15 minutes so they spend that time hiking
subtract the 15 mins of hiking from the total 50 of exercises = 35 for other body exercises
Hope this helped!
First subtract the constant to the other side to simplify it for now
y-5=-x^2+6x
Then pull out a common factor so the coefficient is x^2
y-5=-1(x^2-6x)
Next you take 1/2 of the b value (-6) and square it to find your c value
[1/2(-6)]^2=9
After that plug 9 into your equation as your c value
y-5=-1(x^2-6x+9)
Adding the C-value (9) causes the equations to become unbalanced so you need to balance them back out by minus 9 to the other side
y-14=-1(x^2-6x+9)
Now you want to simplify the equation on the right side.
y-14=-1(x-3)^2
Finally you want to add the constant back to the right side.
y=-1(x-3)^2+14 <——— vertex form
maximum=(3,14)
Answer:
∠GEF
Step-by-step explanation:
The vertex is at E, meaning that it must be listed in the middle.
Therefore, the angle becomes ∠GEF.
Answer:
520
Step-by-step explanation:
If you make it into a proportion where the percent of boys is 85% then you get 85/100=442/w. When you cross multiply you get 85w=44200. Then you simplify and get w=520 so there are 520 students in total
