1. 94/100=0.94=94%
2.15/20=0.75=75%
3. 4/10=0.4=40%
4. 3/100=x/100 》x=3
5. 80/100=x/30 》x=2400/100=24
6. 30/100=x/10 》x=3
7. 2/5=0.4=40%
8. 60/100=x/5 》 x=300/100=3
9. 50/100*x=150 》 50x=15000 》x=300
10. 3/5=0.6=60% 》 100%-60%=40%
Answer:
27 temporary employees
Step-by-step explanation:
Given information: 30 employees, 90% temporary
To find the number of temporary employees we can do: 30*90%=30*0.9=27
There are 27 temporary employees
10 - 2x
10 - 2(7)
= 10 - 14
= -4
For this case we have the following equation:
h = -16t ^ 2 + 32t + 6
Deriving we have:
h '= -32t + 32
We equal zero and clear t:
-32t + 32 = 0
32t = 32
t = 32/32
t = 1 s
Then, the maximum height is given by:
h (1) = -16 * (1) ^ 2 + 32 * (1) + 6
h (1) = 22 feet
Answer:
It takes the ball to reach its maximum height about:
t = 1 s
The ball's maximum height is:
h (1) = 22 feet
