For question 1)
During the 8-9 , Mr hare travel 40miles
For the time 9 onwards they travel concurrently,
Let x be the distance covered by both since they can only meet if they covered the sams distance,
x/50 = x/40 -1 ,where the 1 is the (8-9) 1 hr
x/40 - x/50 = 1
x = 200
Time take by Mr Hare = 200/ 40 = 5
from 8 add 5 hours will be 1
ans is b
2)
during 8- 9 hare travelled 50miles
let x be the distance
x/55= x/50-1
x/50-x/55=1
x=550miles
time taken by hare = 550/50=11 hr
ie when they first meet it will be 7pm
so ans is b 8
the baseball team must win 22 more games to win 60% of total games played in the season.
/////////////////////////////////////////////////////////////////////////////////////
we know that the team played 75 games and will play 45 more games.
1st step: 75 + 45 = 120
2nd step: find 60% of 120 which is 72
3rd step: 72 - 50 = 22
Answer:
K(x, y) —> K’(-x, y - 7)
Step-by-step explanation:
The coefficients of x4 is 9. It has factors of 1, 3, and 9. The constant is 4. It has factors of 1, 2, and 4.
The (positive and negative) ratios of the factors of the coefficient of the x4 and the constant 4 are the potential rational roots of the function.
The answers are:
1, -1, 3, -3, 9, -9, 1/2, -1/2, 3/2, -3/2, 3/4, -3/4, 9/2, -9/2, 9/4, -9/4
Answer:
A
Step-by-step explanation:
50 plus 50 is the easiest number to add so in the associative property you put the easiest problem in parentheses so you can do it first like answer A is
