<u><em>Answer:</em></u>

Evans was the fastest


<u><em>Explanation:</em></u>

<u>The relation between velocity, time and distance is as follows:</u>

velocity = \frac{distance}{time}


<u>1- For Cutwright:</u>

We have the time = 84 minutes and the distance = 35 laps

<u>This means that:</u>

velocity = \frac{35}{84} = 0.61667 lap/minute


<u>2- For Evans:</u>

We have time = 96.6 minutes and distance = 42 laps

<u>This means that:</u>

velocity = \frac{42}{96.6} = 0.43478 lap/minute


<u>3- For Loza:</u>

We have time = 102.6 minutes and distance = 38 laps

<u>This means that:</u>

velocity = \frac{38}{102.6} = 0.37037 lap/minute


Based on the above calculations, we can note than Evans was the fastest


Hope this helps :)

See who got the most laps per minute kinda like miles per hour
Cutwright: 35/84=.416 laps per min
Evans: 42/96.6=.435 laps per min
Loza: 38/102.6=.370 laps per min

Evans drove the fastest with a speed of .435 laps per min

Q: A cell phone company charges $60.00 a month for up to 1 gigabyte of data. The cost of additional data is $0.05 per megabyte.
DiKsa [7]

The linear equation which can be used to determine a user's monthly

bill is c = 60 + 0.05 d ⇒ D

Step-by-step explanation:

The given is:

  • A cell phone company charges $60.00 a month for up to 1 gigabyte of data
  • The cost of additional data is $0.05 per megabyte
  • d represents the number of additional megabytes used
  • c represents the total charges at the end of the month

We need to find which equation can be used to determine a user's monthly bill

The form of the linear equation is y = mx + b, where b is the constant amount and m is the rate of change

∵ The company charges $60.00 a month for up to 1 gigabyte of data

- That means it is a constant amount each month

∴ b = 60

∵ The cost of additional data is $0.05 per megabyte

- That means it depends on the number of additional megabyte,

   so it is not constant, it is the rate of change

∴ m = 0.05

∵ d represents the number of additional megabytes

∴ x = d

∵ c represents the total charges at the end of the month

∴ y = c

Substitute y by c, m by 0.05, x by d and b by 60 in the form of the linear equation above

∴ c = 0.05 d + 60

- We can rearrange the terms of the right hand side

∴ c = 60 + 0.05 d

The linear equation which can be used to determine a user's monthly

bill is c = 60 + 0.05 d

If f(x) = 3x2, what is the x-coordinate of the point of intersection of the graphs of y = f(x) and y = f(x − 4)?
Minchanka [31]

Step-by-step explanation:

When f(x) = f(x - 4), 3x² = 3(x - 4)².

=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.

The x-value is 2.

A restaurant owner made a list of the number of meals ordered last night. She found that 42 people ordered chicken Parmesan, 39
jasenka [17]

Answer:

29/110

Step-by-step explanation:

There are a total of 110 orders at the restaurant, so that will serve as the denominator. There are 29 meatballs, so that will be the numerator. Combine the two and you get 29/110. Experimental probability is what happens in the experiment like this question. Theoretical probability is "real math" as in 1/3.

Solve the exponential equation: 4x - 2 = 2x​
svetlana [45]

Answer:

x= 1

Step-by-step explanation:

Solve

Let's solve your equation step-by-step.

4x−2=2x

Step 1: Subtract 2x from both sides.

4x−2−2x=2x−2x

2x−2=0

Step 2: Add 2 to both sides.

2x−2+2=0+2

2x=2

Step 3: Divide both sides by 2.

2x

2

=
