A group of friends traveled at a constant rate. They traveled 2/5 of a mile in 1/4 of an hour.Which of the following statements are true about this unit rate? Select all that apply.A divide 2/5 by 1/4 to find the unit rate per hour B The average speed will be less than 1 mile per hour because the group travels less than a fourth of a mile in1/4 of an hour C The group traveled at an average speed of 1 3/5 miles per hour.D The average speed will be greater than 1 mile per hour because the group travels more than a fourth of a mile in1/4 of an hour .E The group traveled at an average speed of 2 1/4 of a miles per hour.
The distance traveled, d = 2/5 miles = 0.4 miles.
The time taken to travel 0.4miles is given as, t = 1/4 hr = 0.25 hr.
Thus, the average speed, s = distance traveled divided by time taken.
i.e.
[tex]\begin{gathered} \text{average speed = }\frac{distance\text{ traveled}}{\text{time taken}}\text{ = }\frac{0.4}{0.25}\text{ } \\ \text{average sp}eed\text{ = 1.6 miles/hr} \end{gathered}[/tex]we can now go through the options and see the correct answers:
option A is correct because unit rate per hour is the same thing as average speed
option B is wrong because average speed is greater than 1mile/hr from our calculation above
option C is wrong because 13/5 gives us 2.6 miles/hr
option D is correct because the average speed is indeed greater than 1
option E is wrong because average speed is 1.6 miles/hr not 2 1/4 miles/hr
Thus, the answers are:

SAT scores are normed so that, in any year, the mean of the verbal or math test score should be 500 and the standard deviation 100. Assuming this is true, answer the following question.
What percentage of students score between 400 and 600 on the verbal SAT? Please round to a whole number.
The percentage of students that score between 400 and 600 on the verbal SAT is 11%.
How to calculate the percentage?It should be noted that from the information, SAT scores are normed so that, in any year, the mean of the verbal or math test score should be 500 and the standard deviation is 100.
Therefore, the percentage of students score between 400 and 600 on the verbal SAT will be:
Z = (625 - 500) / 100
Z = 125 / 100
Z = 1.25.
We will then look at the z table. This will be:
P(Z > 1.25) = 0.11

Suppose you have a $60000 loan with an annual percentage rate of 8% for 25 years? Requires monthly payment?
The required monthly payment is $ 180,000
How to calculate SI?Simple interest is the cost of borrowing money that does not take compounding into consideration. In other words, just the principal is affected by simple interest. Simple interest is calculated by multiplying the principal by the time, interest rate, and time period. "Simple Interest = Principal x Interest Rate x Time" is the written formula.
Given: Principal= $60000
Rate= 8% and time= 25 years
To calculate the monthly payment use the formula:
Simple interest=PRT/100
= 60,000×8×25/100
=120,000

Provide your answer below:
The domain of f⁻¹(x) is (9,∞).
The function we have is
f(x) = 4x² + 9 for x ≤ 0
Now, let us find the inverse of the function f(x),
To find the inverse of f(x),
Replacing f(x) with f(y)
f(y) = 4y² + 9
Now the equation is,
x = 4y² + 9
y² = (x-9)/4

how could you use a graph of a proportional relationship to find any ratio in the the proportional relationship why does this work?
When the graph of a proportional connection passes through the origin, the ratio in the proportional relationship can be found.
How to illustrate the information?The connection is proportional if the graph is a line through the origin. This relationship is non-proportional unless the line or ray is non-proportional. K = y/x is the formula for the constant of proportionality. The formula for the slope of a straight line with respect to the origin is the same as this.
If the graph is a line or lines through the origin, the relationship is proportional. If the line or ray does not pass through the origin, it will not be proportional. Also, anything that is not linear is not proportional

Brian's final exam in math had two parts. He had a total of 60 minutes to complete the entire exam. He spent 15 minutes on Part 1 of the exam. Write and solve an equation to show how much time he had left to complete Part 2.
m over 15 equals 60; m = 900 minutes
m − 15 = 60; m = 75 minutes
15 + m = 60; m = 45 minutes
15m = 60; m = 4 minutes
Answer:
15 + m = 60; m = 45 minutes
Step-by-step explanation:
Hello!
According to the question He had a total of 60 minutes to complete the entire exam. He spent 15 minutes on Part 1 of the exam. how much time he had left to complete Part 2.
Let's make an equation where the time spent on part 1 which is 15 + m which is minutes remaining for part 2 is equal to Total minutes which is 60 minutes
So, if we put it together;
15 + m = 60
So, let's solve for m
15 + m = 60
Substract 15 from both sides
15 - 15 + m= 60 - 15
m = 45
So, the equation is 15 + m = 60 and he had 45 minutes of time remaining to complete part 2.
noah is running a portion of a marathon at a constant speed of 6 miles per hour.
The miles he ran in 4/3 hours at a constant speed of 6 miles per hour is 8 miles.
What is the average speed?The average speed is the ratio of total length traveled to total time taken to travel that length. Average speed is the total distance travelled per time.
Average speed = the total distance / total time
Given that Noah's average speed is 6mph
From the above formula, to determine miles run is average speed x time
The Total miles he ran in 1 hour = 6 x 1 = 6 miles
Total miles he ran in 1/2 hours = 6 x 1/2 = 3 miles
Total miles he ran in 1 and 1/3 hours = 6 x 4/3 = 8 miles
The formula for the total time: total distance / average speed
The Time it took Noah to run 1 and 1/2 miles = 3/2 ÷ 6 = 1/4
Time it took Noah to run 9 miles = 9 ÷ 6 = 1 1/2
Time it took Noah to run 4 and 1/2 miles = 9/2 ÷ 6 = 3/4
