A highway sign shows a speed limit of 60 miles per hour. Which of the following car speed measurements represent the same level of accuracy compared to the speed limit sign? Check all that apply. A. 64 mph B. 56 mph O C. 48 mph O D. 68 mph​

Answers

Answer 1

Answer:

B and C

Step-by-step explanation:

Answer 2

IT is found that B. 56 mph and C. 48 mph car speed measurements represent the same level of accuracy compared to the speed limit sign.

What is speed?

Speed can be calculated as the ratio of distance traveled to the time taken

We can see that As the speed limit on the highway is 60 miles per hour and the speeds mentioned above are below the speed limit.

The legal top speed at which a vehicle may travel on a specific section of road is determined by speed limits for road traffic, since they are utilized in the most of countries.

On a traffic sign, it is known that the maximum allowed speed is typically displayed and expressed in kilometers per hour (km/h) or miles per hour (mph).

Using the quadratic formula to solve 7x2 -x = 7, what are the values of x?

Answers

Answer:

x=-7

Step-by-step explanation:

7x2-x=7

7x2=14.

14-x=7

When you finished the last step, you will subtract 14 to both sides.

14-x=7

14-14-x=7-14

this will cancel out the 14 on the left.

And will leave you with:

-x=7-14

7-14 is -7.

and this will get you to

-x=-7

To finish this off, you have to turn the negative x/variable, into a positive x/variable.

So, you will divide both sides of the equation by the same term.

-x = -7

into

[tex]\frac{-x}{1} =\frac{-7}{1}[/tex]

and it will be -7.

I hope this helps      :)

There is a line that includes the point (4,8) and has a slope of 4 What is its equation in slope- intercept form

Answers

Answer:

y=4x-8

Step-by-step explanation:

1) The slope-intercept form of an equation looks like this:

y=mx+b

The m stands for the slope and the b stands for the y-intercept. We need two points on the line to write out this equation.

2)We have the slope you entered in, so we'll plug that in first:

y=4x+b

3) Now, let's plug in that point you entered in to solve for b:

​ y=4x+b

8=4(4)+b

8=16+b

8-(16)=b

-8=b

   

4) Now that we have both our slope, m, and our y-intercept, b, values, we can plug them in to get our equation:

y=mx+b

y=4x-8

Ben wants to have his birthday at the bowling alley with a few of his friends, but he can spend no more than $80.

Write an inequality that represents the total cost of Ben’s birthday for p people given his budget.

Answers

Answer:

45+5.50p=80

Step-by-step explanation:

45 is the flat fee and 5.50 is the shoe rental and unlimited bowling, so p is next to that because its 5.50 PER person so if ben had 2 people it would be 5.50 times 2 plus 45. But remember it cannot be over 80. please mark brainliest
