Answer:
Johnny needs to score 98 on third test to raise average to 94
Step-by-step explanation:
Given that average of two tests is 92.
The score of next test has to be found that means there will be a total of 3 tests.
The average will be:
![Avg = \frac{test1+test2+test3}{3}](https://tex.z-dn.net/?f=Avg%20%3D%20%5Cfrac%7Btest1%2Btest2%2Btest3%7D%7B3%7D)
It is also given that he has to raise his average to 98
We have to use the average formula for finding the third value
So,
![94 = \frac{92+92+test3}{3}\\94*3 = 184+test3\\282 = 184+test3\\test3 = 282-184\\test3 = 98](https://tex.z-dn.net/?f=94%20%3D%20%5Cfrac%7B92%2B92%2Btest3%7D%7B3%7D%5C%5C94%2A3%20%3D%20184%2Btest3%5C%5C282%20%20%3D%20184%2Btest3%5C%5Ctest3%20%3D%20282-184%5C%5Ctest3%20%3D%2098)
Hence,
Johnny needs to score 98 on third test to raise average to 94
Answer:
400 ft
Step-by-step explanation:
h(t)= -16t^2 + 160t
The vertex is found at
h = -b/2a where b is the coefficient of t and a is the coefficient of t^2
= -160/(2*-16)
-160/-32
5
The time where the maximum occurs is at t=5
To find the maximum substitute into the function
h(5) = -16 (5)^2 +160*5
= -16*25 +800
=-400+800
= 400
The maximum height is 400 ft
Answer:
Given that speed(v) = 20km/h and time(t) = 50 min
We have to find distance (d)
First convert speed into m/s
v = (20*1000m)/(1*3600s)
v = (50/9) m/s
Now convert time into second
t = 50*60 = 3000 sec
As we know that
d = v*t = (50/9)*3000 = 50000/3
d = 16666.67m or 16.67km
Ans: 16666.67m or 16.67km
