The graph shows a proportional relationship between the distance traveled in miles and time in hours. Billy incorrectly says that the speed of the car is 1/60 mile per hour. What is the speed of the car? What error might Billy have made?
Answer:
Step-by-step explanation:
Since, speed of a car = [tex]\frac{\text{Distance traveled}}{\text{Time taken}}[/tex]
From the graph attached,
A point (1, 60) lies on the line shown in graph.
At this point speed of the car = [tex]\frac{\triangle y}{\triangle x}[/tex]
[tex]=\frac{60-0}{1-0}[/tex]
= 60 miles per hour
But Billy says the speed of the car is [tex]\frac{1}{60}[/tex] miles per hour.
So the error in the Billy's answer is that he has used the wrong formula to calculate the speed.
(As per Billy, speed = [tex]\frac{\text{Time taken}}{\text{Distance covered}}[/tex])

At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions. If x represents the number of hand soaps and y represents the number of lotions she bought, which inequality best represents her purchase?
x + y 12
x + y ≤ 12
x + y ≥ 12
Answer:
the answer is b
Step-by-step explanation:
edge 2021
The inequality which best represents the purchase is x + y > 12.
What is Linear Inequalities?Linear inequalities are defined as those expressions which are connected by inequality signs like >, <, ≤, ≥ and ≠ and the value of the exponent of the variable is 1.
Given that,
At an end of the year sale, Gabriela bought more than 12 bottles of hand soaps and lotions.
Let x represents the number of hand soaps she bought.
Let y represents the number of lotions she bought.
x + y is more than 12.
So the inequality is,
x + y > 12
Hence the correct inequality is x + y > 12.

Aubrey and Charlie are driving to a city that is 120 miles from their house. They have already traveled 20 miles, and they are driving at a constant rate of 50 mi/h. Part A Write the function that models their distance from home as a function of time. f(x) = x + Part B What is a reasonable domain for this situation? ≤ x ≤
their distance from home as a function of time
[tex]f(x)=50x+20[/tex]
The reasonable domain for this situation is
[tex]0\leq x\leq 2[/tex]
Given :
Aubrey and Charlie are driving to a city that is 120 miles from their house. They have already traveled 20 miles, and they are driving at a constant rate of 50 mi/h.
Given driving speed is 50 miles per hour
They already travelled 20 miles. We need to frame linear equation because we are given with constant rate.
Linear equation is [tex]f(x)=mx+b[/tex]
where m is the constant rate and b is the initial miles travelled
m=50 and b=20
the function f(x) is the distance from home
[tex]f(x)= 50x+20[/tex]
Now we find out the domain x. Given that they travelled 120 miles
so f(x) is 120
[tex]120=50x+20\\120-20=50x\\100=5x\\x=2[/tex]
Domain is the number of hours travelled
hours cannot be negative . So the domain x for this situation is
[tex]0\leq x\leq 2[/tex]

Identify the equation of the line graphed (I need help can someone explain)
Answer:
D.) 5x - 2y = 2
Step-by-step explanation:
1. Find all of the options and convert them to slope-intercept form by isolating y. If you isolate y on all of them, you should get that A is y =-2/5x - 1, B is y = 2/5x - 1, C is y = -5/2x - 1, and D is y = 5/2x - 1.
2. Use logic. This line cannot be negative, because negative lines go up to down, not down to up. That cancels out the possibility of A.) and C.) being answers. Now, we know that the slope has to be more than 1 because it is more compressed than that of a line with a slope of 1. The only slope that is more than 1 is D, so that makes D the answer (If you didn't understand this step, go to step 3).
3. Find the slope (This step does not need to be done if you understood Step 2). Take 2 points to be able to find the slope. Two random points on this line are (2,4) and (0,-1). Next, plug them into the formula to find slope. 4-(-1)/2-0 = 5/2, so the slope is 5/2. The only equation with a slope of 5/2 is D. D is the answer.
Answer: D.) 5x - 2y = 2

There are 5,000 books in the town's library. Of these, 4,300 are fiction. To find the percent of the books that are fiction, first set up the percent equation. Then find the percent.
A. 4,300 = m / 5,000
B. 4,300 = m x 5,000
C. 5,000 = m / 4,300
D. 5,000 = m x 4,300
Answer:
B
Step-by-step explanation:
The percent of the books that are fiction is 86% and the percent equation is 4300=m×5000. Therefore, option B is the correct answer.
Given that, there are 5,000 books in the town's library.
What is percentage?Percentage is defined as a given part or amount in every hundred. It is a fraction with 100 as the denominator and is represented by the symbol "%".
Let the percent of the books that are fiction be m
So, m= 4300/5000
4300=m×5000
Percentage =4300/5000 ×100
= 86%
The percent of the books that are fiction is 86% and the percent equation is 4300=m×5000. Therefore, option B is the correct answer.

A driver is 15 feet below the surface of the water 10 seconds after he entered the water and 90 feet below the surface after 40 seconds. What is the rate of change?
Answer:
[tex]\frac{-75ft}{30sec}[/tex] or simplified would be [tex]\frac{-2.5ft}{sec}[/tex]
Step-by-step explanation:
In order to calculate the rate of change, we must subtract his end position and end time by the starting position and starting time. We are using the -15 feet since it is below the surface area as the starting position and the 10 seconds as the starting time. We make each of these into a fraction and subtract like so...
[tex]\frac{-90ft - (-15ft)}{40sec - 10sec} =[/tex] rate of change
[tex]\frac{-75ft}{30sec} =[/tex] rate of change
[tex]\frac{-2.5ft}{sec}[/tex] = rate of change
Therefore, we can see that the rate of change of the diver is [tex]\frac{-75ft}{30sec}[/tex] or simplified would be [tex]\frac{-2.5ft}{sec}[/tex]
