Answer:
3 tires per hour
Step-by-step explanation:
Bernard works for a business that sells and repairs tires. He can repair 24 tires in an 8 hour work day. What is Bernard's unit rate for the number of tires repaired in one hour?
Number of tires repaired per day = 24 tires
Number of time used to repair tire per day = 8 hours
What is Bernard's unit rate for the number of tires repaired in one hour?
Number of tires repaired in one hour = Number of tires repaired per day / Number of time used to repair tire per day
= 24 tires / 8 hours
= 3 tires per hour
The unit rate for the number of tires repaired in one hour is 3 tires per hour
Answer:
5/8
Step-by-step explanation:
First we need to figure out how many girls and boys there are.
g = girls
b = boys
g = b+8 ( eight more girls than boys)
b = g-8
There are 32 students)
g+b =32
Substitute b = g-8 into the equation
g + (g-8) = 32
Combine like terms.
2g-8 = 32
Add 8 to each side.
2g -8+8 = 32+ 8
2g = 40
Divide by 2
g = 20
There are 20 girls
The experimental probability of picking a girl is
girls/ total
20/32 = 5/8
The given line (in blue) is a vertical line, so it is in the form
Ax=C (i.e. with the y-term missing).
Since we know that the line passes through (-2,2), and (-2,-3), this means that all points on the line has the x-coordinate equal to -2 (characteristic of vertical lines).
The equation is therefore
x=-2, or alternatively
x+2=0
The slope is 4/5 assuming time is along the bottom of the graph.
Answer:
8) 1
9) -4
10) -3
11) -1
12) 1
13) doesn't exist
14) 1
15) doesn't exist
Step-by-step explanation:
8) when we approach x=-8 from left and from right, the function tends towards the value 1
9) when we approach x = -7, from the left the function gets towards 0, while when we approach it from the right it gets closer to -4
10) f(-3) = -3
11) When x approaches the value 4 from the left and from the right, f(x) gets closer to -1
12) f(4) is defined as 1
13) f(6) doesn't exist
14) When x approaches 6 from the left and from the right, the function approaches 1
15) When x approaches the value 7 from the left the function gets closer to 2, while when we approach x = 7 from the right the function gets toward 7. Because of this discrepancy, the limit doesn't exist.
