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.

Answer:
70.68 inch is the volume of the rectangular prism
Step-by-step explanation:
V = w × h × l
V = 3.8 inch × 3 inch × 6.2 inch
V = 70.68 inch is the volume of the rectangular prism
To check:
70.68 ÷ 3.8 ÷ 6.2 = 3 inch (height)
70.68 ÷ 6.2 ÷ 3 = 3.8 inch (width)
70.68 ÷ 3.8 ÷ 3 = 6.2 inch (length)

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.

Ben starts walking along a path at 3 mi/h. One and a half hours after Ben leaves, his sister Amanda begins jogging along the same path at 7 mi/h. How long (in hours) will it be before Amanda catches up to Ben?
Enter the exact answer.
Hint: The distance formula is that distance = rate * time, so for example in one and a half hours, Ben has walked 3 * 1.5 miles.
Answer:
Step-by-step explanation:
Distance = speed * time
For Ben:
speed = 3mi/hr
Time = (x+1.5)hr
Distance = 3 * (x+1.5)
Distance = 3(x+1.5)
For Amanda:
Speed = 7mi/hr
time = 1x
Distance = 7x
Since they cover the same distance then:
3(x+1.5) = 7x
3x + 4.5= 7x
3x-7x = -4.5
-4x =-4.5
x = 4.5/4
x = 1.125 hr
The time taken by Amanda is 1.125 hr

Help! Best answer = Braniest
Answer:
x=20
Step-by-step explanation:
Complementary = 2 angles which = 90 degrees
so 2x+10 + x+20 =90
combine like terms
3x+30=90
-30 -30
3x=60
x=20
lets check! (2(20)+10) + (20+20)
50 + 40 =90 degrees
Answer:
x = 20
angle 1 = 50
angle 2 = 40
Step-by-step explanation:
complementary angles add up to 90
so, you can make this equation:
2x + 10 + x + 20 = 90
combine like terms
2x + x + 10 + 20 = 90
3x + 30 = 90
subtract 30 from both sides of the equation
3x + 30 - 30= 90 - 30
3x = 90 - 30
3x = 60
divide both sides of the equation by 3
3x/3 = 60/3
x = 60/3
x = 20
now, plug x into the angles:
2x + 10
2 * 20 + 10
40 + 10
the first angle is 50°
x + 20
20 + 20
the second angle is 40
Determine whether the events are independent or dependent. Explain your reasoning. Returning a rented movie after the due date and receiving a late fee
Answer:
They are dependent
Step-by-step explanation:
A dependent event is one in which its chances of happenning greatly relies on another event. An independent event which is the opposite is one in which its chances of happening is unaffected by another event. In the event described in the question above returning the rented movie after the due date would result in receiving a late fee.
One of the events- receiving a late fee, depends on when the rented movie is returned. This means that the events are dependent.

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

Answer:
80 milligrams
Step-by-step explanation:
The volume of bottle is 16-ounce, and the amount of vitamin C in the bottle is 200 mg.
Since the 16-ounce bottle of orange juice says it contains 200 milligrams of vitamin C, which is 250% of the daily recommended allowance of vitamin C for adults. Then for 100% of the daily alowence, we need to multiply 200/250 by 10. We get 80. The picture shows a dubble number line for paper homework. Good luck!
The sales price for a jacket is $30. It is 75% off. What is
the original price?
Answer:
$120
Step-by-step explanation:
$120-75% is $30. 1/4 of $120 is $30, so 3/4 is $90. $120-$90 is $30. To find the answer to future equations like this, just multiply the sales price by 4 if the percentage is 75.
It is not $52.50, because 75% of that is $39.375, making that one's sales price 13.125.
Answer:
$52.50 is the original price
Step-by-step explanation:
In order to find the answer, multiply $30 * 0.75 which equals $22.50 and add $30 + $22.50 which would equal $52.50
