Divide 3.42 by 0.76 to equal 4.5 or
3.42 / 0.76 = 4.5
Therefore, James lives 4.5 times the distance Megan lives from the school.
Answer:
4310 in all
2750 went to Hartville charity
Step-by-step explanation:
they collected 3,288 one week then 1,022 the next.
so then you add them up
3,288 + 1,022 = 4310
then they donated 1,560. so then you subtract.
4,310 - 1,560 = 2,750
To solve this exercise you must follow the proccedure below:
a) Find the maximum height of the tennis ball:
You have that the path of the ball can be represented by h=-16t²<span>+18t+5. Then:
t=-b/2a
t=-18/2(-16)
t=0.562
</span>
h=-16t²+18t+5
h=-16(0.562)²+18(0.562)+5
h=10.06
b) How long will it take to reach the ground?
h=-16t²+18t+5
h=0
-16t²+18t+5=0
You must apply the quadratic equation:
t=(-b±√(b^2-4ac))/2a
a=-16
b=18
c=5
When you substitute the values, you obtain:
t=1.35
Answer:
78.54
Step-by-step explanation:
Area of a circle = A=πr2
A=π(5)2
A= 78.54
