Use the graph that shows the number of laps completed over time. Find the slope of the line.
Answers
By using the given graph, we will see that the slope of the linear equation is:
a = 0.5 laps per minute.
How to find the slope of the line?
For a linear equation:
y = a*x + b
Where a is the slope and b is the y-intercept.
We know that if the line passes through two points (x₁, y₁) and (x₂, y₂), then the slope is:
a = (y₂ - y₁)/(x₂ - x₁).
So we need to look at the graph and identify two points, we will use:
(10 min, 5) and (20 min, 10)
So the slope is:
a = (10 - 5)/(20 min - 10 min) = 0.5 laps per minute.

Eva deposited $50 in an account earning 10% interest compounded annually.
To the nearest cent, how much interest will she earn in 2 years?
Answers
Step-by-step explanation:
Simple Interest = P.R.T / 100
P= Principal (Amount invested) =$30
R= Rate= 10%
T= Time = 3 years
Therefore, Simple Interest (1):
I = PRT/100
1 = ($30 * 10 * 3 ) / 100
I = $900 / 100
1 = $9

Consider the information about the number of customers that select various frame
colors at a frame store one day.
• 15 customers select white frames.
• 30 customers select black frames.
• 45 customers select gold frames.
Part A
If there are a total of 2.200 customers that order from the frame store one month, what
is the best approximation for how many customers that month select a black frame?
A. 367 customers
B. 733 customers
C. 1, 100 customers
D. 1. 167 customers
Answers
Answer:
B. 733 customers
Step-by-step explanation:
15+30+45=90
since 30 people select a black frame, 1/3 of the customers picked black frames. If this data is consistent through the month (which we have to assume it is) then that means 1/3 of customers select a black frame on average. 1/3 of 2,200 is about 733, so we can assume, using the data given, that about 733 customers selected black frames! :)
