A street that is 164m long is covered in snow. City workers are using a snowplow to clear the street. The snowplow has tires tha

t are 2.1m in diameter. How many times does a tire have to turn in traveling the length of the street? Use the value 3.14 for π. Round your answer to the nearest tenth. Do not round any intermediate steps.

The number of times the tires will have to spin is 24.9 times. How I got this was by finding the circumference, the equation in this case where pi is 3.14 is 3.14(2.1). That equals 6.594, then you divide 164 by 6.594 to get 24.87109 blah blah and you round that up to 24.9.

Rita is starting a running program. The table shows the total number of miles she runs in different weeks. What is the equation
prisoha [69]

Answer:

The best fit line is y = 1.671x + 4.699

Step-by-step explanation:

We are given,

The table representing the number of miles run in different weeks is,

Week                        Miles Run

1                                        5

2                                       8

4                                       13

6                                       15

8                                       19

10                                     20

Using the linear regression calculator, we see that,

<h3>The equation of the line best fit for the data is y = 1.671x + 4.699.</h3>

For each value of y, determine whether it is a solution to -2y+75-5.<br> Is it a solution?
ser-zykov [4K]

Answer:

• No

• Yes

• Yes

• No

Step-by-step explanation:

To determine if the 4 given values of y are solutions to the inequality, start by solving the inequality. Solving an inequality is just like that of an equation, except that the direction of the sign changes when the inequality is divided by a negative number.

-2y +7≤ -5

Subtract 7 on both sides:

-2y≤ -5 -7

-2y≤ -12

Divide by -2 on both sides:

y≥ 6

This means that the solution can be 6 or greater than 6.

-10 and 3 are smaller than 6 and are not a solutions, while 7 and 6 satisfies the inequality and are therefore solutions.

_______

Alternatively, we can also substitute each value of y into the inequality and check if the value is less than or equal to -5.

Here's an example to check if -10 is a solution.

-2y +7≤ -5

When y= -10,

-2y +7

= -2(-10) +7

= 20 +7

= 27

Since 27 is greater than 5, it is <u>not</u> a solution to the inequality.
