Hey, looks like when she doesn't study, she ALWAYS fails. Don't mean to insult though.
Let's see the difference between the three numbers. 63-58=5. 68-63=5.
We know the difference between each assessment she scores is 5 now!!
Let's put it to use.
Although you don't have multiple choice answers...
after 4 assessments(not including first 3), her score will be above 85!!
Including the first 3 assessments, her score would be above 85 after 7 assessments!!
anyways, I hope this helps!!
Answer: A. y= 5x(x-2)
Step-by-step explanation:
To begin with, this graph has two X values, making it a parabola
Parabola's are NOT linear.
Answer:
600 m
Step-by-step explanation:
The circumference of a tire is the distance around it. The distance around these tires is 1 m.
Since the tires revolve 15 times per second, this means every second the tires travel 15 m.
This means that in 40 seconds, the tires travel
15(40) = 600 m.
Answer:
Full drum 80 dollars
one lid missing
earn 10 dollars less
Step-by-step explanation:
We need to find the surface area
SA = 2 pi r^2 + 2 pi rh
The diameter is 2 so the radius = 2/2 =1
SA = 2 * pi * 1^2 + 2 * pi * 1 * 3
= 2 pi + 6pi
= 8pi
Using pi = 3.14
SA = 8 *3.14 = 25.12 ft^2
We get 3.18 per ft^2
25.12 * 3.18 =79.88
To the nearest dollar
80 dollars
If one of the lids is missing
SA = pi r^2 + 2 pi rh
pi + 6pi
7 pi
Using pi = 3.14
SA = 7 *3.14 = 21.98 ft^2
We get 3.18 per ft^2
21.98 * 3.18 =69.90
To the nearest dollar
70
The difference is 10 dollars
