Answer:
17 seconds
Step-by-step explanation:
h(t) represents height, we want to know when the ball will return to a height of 28 feet. So our equation is..
28 = -2t² + 34t + 28
Now solve for t...
0 = -2t² + 34t (subtract 28 from both sides)
0 = t² - 17t (divide both sides by -2)
0 = t(t - 17) (factor out a t)
So
t = 0
or
t - 17 = 0
t = 17
0 seconds is the initial height. At 17 seconds, the ball will return to that height
Answer:
q=723 or something close to that
Step-by-step explanation:
First you subtract 12,000 from 21,853= 853
Second you divide that by 1.18 to get q by itself
Done.
Answer: $18
Step-by-step explanation:
You had a total of $60.
You spent 30% of your money on shorts.
The question would like to know what that 30% translates to in actual dollars so you need to find out what 30% of $60 is:
= 30% * 60
= $18
Answer:
the answer is 12 i think thank me later explain to me if my answer is wrong
These are similar triangles so proportions hold. the short side to the bottom side proportion must be the same in both triangles. to solve it
25/30 = 35/x. (25+10=35 is the side of the bigger triangle
cross multiply and solve for x
25x=1050
x=1050/25=42
