Doug and Emily are driving cars on a track, and they both do 20 laps around a 1-mile track. Doug drives an average of 60 miles per hour around the track while Emily drives at an average of 80 miles per hour. When Emily finished her 20 laps how many laps does Doug have left?
Answer:
When Emily finishes 20 laps Doug has to finish 5 laps.
Step-by-step explanation:
To find how many laps does Doug have left, we need to calculate the time that Emily takes to finish 20 laps:
[tex] t = \frac{x}{v} [/tex]
Where:
x: is the distance = 1 mile
t: is the time
v: is the speed of Emily = 80 mi/h
The time that takes Emily to do 20 laps is:
[tex] t = 20*\frac{1 mile}{80 mile/h} = 0.25 h [/tex]
Now, we can find the number of laps:
[tex]x = v*t = 60 miles/h*0.25 h = 15 miles*\frac{1 lap}{1 mile} = 15 laps[/tex]
[tex] laps = 20 - 15 = 5 [/tex]
Therefore, when Emily finishes 20 laps Doug has to finish 5 laps.
I hope it helps you!

Which is a TRUE statement about the transformation shown?
Statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.
We can see that both the figures are identical but the vertices A and C have changed the position.
This shows that it is a reflection of the image given originally as the vertices have only being flipped.
Now, we can also see that the shape and size both are same of the image and the pre-image. Also, the sides of the triangle are equal to one another.
The angles are also equal to one another.
This means that they are congruent to each other.
Therefore, statement (C) The graph show a reflection and the pre-image and image are congruent is the correct option.

A community garden offers two different square-shaped plots of growing space. The larger plot measures one square meter greater than the smaller one. The combined lengths of the two gardens is 3+2 radical 2 meters. What is the area of garden 1?
Answer:
3 + 2√(2)
Step-by-step explanation:
Since the larger plot is 1²m greater than the smaller one.
Let x denote the length of the smaller one, this implies that the larger would be x + 1.
Since the combined length is 3 + 2√(2) we have:
x + (x + 1) = 3 + 2√(2)
2x + 1 = 3 + 2√(2)
2x = 2 + 2√(2)
x = 1 + √(2)
This is the length of the smaller plot. It's area would therefore be:
x² = [1 + √(2)]² = 1 + 2√(2) + 2 = 3 + 2√(2)

The sum of ages of father amd his son is 60 years. After 14 years, father's age will be three times the age of his son. Find their present ages.
Answer:
Father age= 52 years
Son age =8 years
Step-by-step explanation:
Given:
⇒ Sum of ages of father and his son = 60 years
⇒ After 14 years - father's age will be 3 times the age of his Son
⇒ Find their present ages
Solution:
According to the given,
The total = 60
Father age = "x " ( unknown)
Son age = 60 - x
In additionally,
Father age = ( x + 14 ) years
Son age = ( 60 - x + 14 )
= ( 74 - x ) years
Setting up the problem:
x + 14 = 3 ( 74 - x )
Removing parentheses:
x + 14 = 3 × 74 - x
Multiply:
x + 14 = 222 - 3x
variable on one side and the other on other side:
x + 3x = 222 - 14
Add/Subtract:
4x = 208
Divide:
4x/4 = 208/4
x = 52
Hence, at present:
Father age = 52
Son age = 60 - 52
→ 8
As a result,
Their present ages:
Father = 52
Son = 8

What is the slope of the line? Please explain your answer.
A.) m=5
B.) m= -5
C.) m=1/5
D.) m= -1/5
Answer: D
Step-by-step explanation: Assuming the left point is A at (-2,2) and the right point is B at (3,1) we can determine the slope by using the “Rise over Run” rule where the change in Y is the “Rise” and the change in X is the “Run”. By setting up the equation y2-y1/x2-x1 we can plug in the coordinates from the variables and get 1-2/3+2 which leaves us with our answer m= -1/5

how to solve christina used 2 1 3 gallons of gas to drive her car 64 1 6 miles. what was the fuel efficiency of her car, in miles per gallon, for the trip? miles per gallon
The efficiency of car is 55/2 MPG
• Fuel efficiency is a measure of how much energy in terms of fuel will be converted to kinetic energy to travel by a car. Most nations use miles per gallon to measure fuel efficiency (mpg).
• A good rule for fuel efficiency is that at least you are getting 23 miles per gallon combined city and highway.
• We calculate fuel efficiency by the formula MPG = (No of miles drove since last fill) / Gallons Based on the given conditions, Formula for MPG = (64 1/6 ) / (2 1/3)
Solving this we get= (64 + 1/6 ) / ( 2 + 1/3)= ((384 + 1)/6) / (7/3) = (385/6) / (7/3)= 55/2
Therefore, the vehicle's efficiency is 55/2 MPG.
