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!

None of the above

Step-by-step explanation:

They are all incorrect answers because the properties are interceptionaly rational.

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.

x and y-intercept :

The x-intercept is where a line crosses the x-axis, and the y-intercept is the point where the line crosses the y-axis. Thinking about intercepts helps us graph linear equations.

Absolute min:

An absolute maximum point is a point where the function obtains its greatest possible value.

Absolute max :

An absolute minimum point is a point where the function obtains its least possible value.

Local Extrema (Local Maxima/Minima): The local maxima and minima on a graph refer to the maximum and minimum points of the graph over a specific interval of the graph as opposed to the entire graph, so there can be multiple local maxima and minima of a given graph.

When considering which points are the absolute maximum and the absolute minimum of a graph, we not only need to consider local extrema (a maximum/minimum of a graph on some interval that contains the point), but we also need to consider the endpoints (the furthest left/right points on our graph). By looking at the y-values for each of these points, we can identify the absolute maximum of the graph as the point with the highest y-value, and we can identify the absolute minimum as the point with the lowest y-value.

Step 1: Identify local maxima/minima, as well as the endpoints.

From this graph, we can see that our graph is on the interval

This means we have our endpoints at [-1,-1] , [4,1] ,

to consider. We also observe that we have one local minima and one local maxima in between these points on our interval. The estimated points are all shown in the image.

No, it is 875%

Step-by-step explanation:

Percent means per cent, as in one cent in a dollar kind of thing, or 1/100.

You find 8.75 as a percent by multiplying it by 100 and adding the % after it.

Diane will walk 1.5 miles more than Sue.

Firstly calculating the speed of Diane and Sue in miles per hour. As per the known fact, 1 hour has 60 minutes.

In 40 minutes Diane walks distance = 2.5 miles

So, converting speed in miles per hour = (2.5 ÷ 40)×60

Speed of Diane in miles per hour = 3.75 miles per hour

In 40 minutes Sue walks distance = 1.5 miles

So, converting speed in miles per hour = (1.5 ÷ 40)×60

Speed of Sue in miles per hour = 2.25 miles per hour

Difference between the distance covered = 3.75 - 2.25

Performing subtraction

Difference between the distance covered = 1.5 miles

Hence, Diane will walk 1.5 miles more than Sue.

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.

Step-by-step explanation:

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)

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

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

The input x = 1 leads to multiple outputs y = 1 and y = 2 simultaneously, which is why choice D isn't a function.

A function is only possible if any input leads to exactly one output only. Choices A,B and C are all functions for this reason.
