Answer:
B.) 1/7
Step-by-step explanation:
you have a total of 15 the you subtract one so you have
15-1= 14
you had 3 dimes and you took one out so you have
3-1=2
so you have 2/14 and in simplest for that is 1/7 because you divide both by 2
I hope this was good enough:
Answer:
24
Step-by-step explanation:
When you are finding a percent of something, you need to move the decimal over to the left twice in the percentage. Like this:
20% = .20
Then, just multiply that by the number you are trying to find the percent of.
.20 x 120 = 24
16 3/4 + 12 3/4
16 +12 = 28
3/4 +3/4 = 1 1/2
28 + 1 1/2 = 29 1/2 hours total
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
<em>I </em><em>think </em><em>41 </em><em>is </em><em>correct </em><em>answer</em>
Step-by-step explanation:
(7+8)-(5+9)+4(2+5)
=15-14+4(10)
=1+40
