Answer:
R(p) = -4p^2 + 300p when p=20.
R(p) = -4(20)^2 + 300(20)
R(p) = -1600 + 6000
R(p) = 4400
The mass when p=20 years is 4400.
74 words in a minute if you divide 2886 by 39
7a+20b = 28-b
7a = 28-b-20b
7a = 28-21b
a= 28/7 - 21/7 b = 4-3b
Answer:
He's expected to hit 320 times.
Step-by-step explanation:
To solve this problem we first need to compute the ratio at which he hit the ball in the last season, to do that we need to divide the number of hits by the number of tries. We have:
ratio = number of hits/ number of tries
ratio = 160/200 = 0.8
Since he's expected to bat 400 times if he maintains the same ratio in this season he'll hit:
number of hits = (number of tries)*ratio
number of hits = 400*0.8 = 320
He's expected to hit 320 times.
