Roberto runs 25 miles. His average speed is 7.4 miles per hour. He takes a break after 13.9miles.How many more hours does he run? Show your work.
Answer:
1.5 hours
Step-by-step explanation:
Number of miles = 25 miles
Average speed = 7.4 miles per hour
Break after 13.9 miles
How many more hours does he run
Speed = distance / time
Total time for 25 miles :
Time = distance / speed
Time = 25 / 7.4
Time = 3.378 hours
Total time to cover 13.9 miles :
Time = 13.9 / 7.4
Time = 3.378 hours
Time = 1.878 hours
Difference = (3.378 - 1.878) hours = 1.5 hours
Hence, he to ran for 1.5 hours after taking a break
The total time required for the 25 miles run is 3.378 hours and he will run for 1.5 hours after the break.
Given information:
Roberto runs 25 miles.
The average speed is 7.4 miles per hour.
He takes a break after 13.9 miles.
Now, speed is defined as the ratio of distance and time.
So, the time taken by him to run first 13.9 miles will be,
[tex]s=\dfrac{d}{t}\\7.4=\dfrac{13.9}{t_1}\\t_1=1.878[/tex]
So, he ran for 1.878 hours to cover 13.9 miles.
Now, the total time of the 25 miles run will be,
[tex]T=\dfrac{25}{7.4}\\T=3.378[/tex]
So, the total time of the run is 3.378 hours.
After the break, he will run for 3.378-1.878 hours = 1.5 hours.
Therefore, the total time required for the 25 miles run is 3.378 hours and he will run for 1.5 hours after the break.

–0.4x – 10 > 14
–0.4x > 4

–0.4x > 24
x < –60
Answer:
d
Step-by-step explanation:
–0.4x – 10 > 14
–0.4x > 24
x < –60
the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.
Inequality refers to a mathematical relationship between two values that are not equal.
The correct work that uses properties of inequality to find the solution to – 0.4 x – 10 > 14 is:
– 0.4 x – 10 > 14
Subtract 10 from both sides:
– 0.4 x > 24
Divide both sides by – 0.4 (note the change in inequality direction when dividing by a negative number):
x < – 60
Therefore, the correct solution to the inequality – 0.4x – 10 > 14 is x < – 60.

A. The distance Steve drives on a road trip is a function of the
number of times he has to go to the gas station.
B. The distance Steve drives on a road trip is a function of the type of
car he has
C. The amount of gas left in Steve's car at his next visit to the gas
station is a function of the distance he drove.
SUBMIT
Answer:
C. The amount of gas left in Steve's car at his next visit to the gas
station is a function of the distance he drove.
Step-by-step explanation:
From the question, the car starts with a full tank of gas and the more the distance covered, the less gas will be left in the car at the next visit to the gas station.
The variables to take note are the distance travelled and the amount of gas left in the car at next visit to the gas station.
This means the farther he drives, the less gas will be left in the car because longer distances travelled consumes more gas in the car thus less gas will be left when the next visit to the gas station occurs.

Find an equation of the line having the given slope and containing the given point.
Slope is -2
Line through (5, -6)
Answer:
y = -2x + 4
Step-by-step explanation:
Pre-SolvingWe are given that a line has a slope (m) of -2 and passes through (5, -6).
We want to write the equation of the line.
There are three ways to write the equation of the line:
Slope-intercept form, which is y=mx+b, where m is the slope and b the value of y at the y-intercept.Standard form, which is ax+by=c, where a, b, and c are free integer coefficients. Point-slope form, which is [tex]y-y_1=m(x-x_1)[/tex], where m is the slope and [tex](x_1,y_1)[/tex] is a point.Any of these forms will work, however let's put it into slope-intercept form as that is the most common way.
SolvingAs we are already given the slope, we can immediately plug that into the equation.
Substitute m with -2.
y = -2x + b
Now, we need to solve for b.
As the equation passes through (5, -6), we can use its values to help solve for b.
Substitute 5 as x and -6 as y.
-6 = -2(5) + b
Multiply.
-6 = -10 + b
Add 10 to both sides.
4 = b
Substitute 4 as b.
y = -2x + 4

It takes 30 mins to shape 10 pots, and heating all 10 pots takes 10 mins. Add 30 and 10 minutes to get: 40 minutes.
Answer:
3p + 10; 40 minutes
Step-by-step explanation:
It takes 3 minutes to shape one pot.
It takes 3p minutes to shape p pots.
A batch of pots has p pots and takes 10 minutes in the kiln.
The total time it takes to make 1 batch is the time to shape the pots, 3p, plus the time in the kiln, 10 minutes.
The expression is
3p + 10
For a batch of 10 pots, p = 10.
3p + 10 = 3(10) + 10 = 30 + 10 = 40
Answer: 3p + 10; 40 minutes

Given that A math class consists of 25 students, 14 female and 11 male. Two students are selected at random to participate in a probability experiment.
Now, since we need to compute the probability that no males are selected, which can also be taken as the probability of both the students selected are girls. Therefore, the probability can be written as,
Probability = (14/25) × (13/24)
= 182/600
