plz i need help Find the perimeter and area of each shape. If you use a formula write it down. Show me your work. 1.) An 8ft by 10 ft rectangle15. 2.) A square with a side of 7in

Answer:

20+0,5m=30+0,25m

0,5m-0,25m=30-20

0,25m=10/0,25

m=40

Step-by-step explanation:

Equation for the given condition is equals to 20+ 0.50m = 30 +0.25m. Value of the m= 40miles.

" Equation is defined as the algebraic expression which is represent by sign of equality."

According to the question,

m represent the number of miles

Cost for blue car rental = $20 + 0.50 per mile

                                       = 20 + 0.50m

Cost for red car rental = $30 + 0.25 per mile

                                     = 30 + 0.25m

Both the cars have same rentals.

Therefore,

Equation for the given condition

  20 +0.50m = 30 +0.25m

⇒0.50m - 0.25m = 30 - 20

⇒0.25m = 10

⇒m = 10 / 0.25

⇒m = 40miles

Hence, equation for the given condition is equals to 20+ 0.50m = 30 +0.25m. Value of the m= 40miles.

Answer:55&71

Step-by-step explanation: The 6 hours is unnecessary info. 63-8=55 and 63+8=71.

The final temperature have the minimum should be 55 and the maximum should be 71.

Since It began at 63°F, and the temperature changed by 8°F over the course of 6 hours.

So here the minimum should be

= 63-8

= 55

And, the maximum should be

= 63 + 8

Answer:

7/21 and 8/21

Step-by-step explanation:

2/7 can be also written as 6/21 and 3/7 as 9/21

so, fraction in between 6/21 and 9/21 is 7/21 and 8/21

The two fraction in between 2/7 and 3/7 are 7/21 and 8/21.

Here,

We have to find two fraction in between 2/7 and 3/7.

What is Whole number?

The numbers which is start from 0 (zero) are called whole number.

Now,

The fraction 2/7 can be also written as,

[tex]\frac{2*3}{7*3} = \frac{6}{21}[/tex]

And, The fraction 3/7 can be also written as,

[tex]\frac{3*3}{7*3} = \frac{9}{21}[/tex]

Hence, we get;

[tex]\frac{6}{21} , \frac{7}{21} ,\frac{8}{21} ,\frac{9}{21}[/tex]

Therefore, The two fraction in between 2/7 and 3/7 are 7/21 and 8/21.

Answer:

0.7

Step-by-step explanation:

10y = 7x + 5

Divide both sides by 10.

y = 7x/10 + 5/10

y = 0.7x + 0.5

On a straight line of the form y = kx + m, k is the slope of the line.

In our line, y = 0.7x + 0.5, k is 0.7. Thus, the slope of our function is 0.7

Answer:

33. D.1/3

34. D. y= x+4

35. Slope= -2/3 Y-intercept= -6

Step-by-step explanation:

For number 33. D. 1/3 is the correct answer.

Start at the point (0,2) Then, Go up 1 and Right 3.

As a result, you land in the point (3,3) This proves that the slope is 1/3.

Note: the line is increasing and going upwards, so the slope is positive.

For number 34. D. y=x+4 is the correct answer.

When writing an equation of a line, the correct format is y=mx+b. We are given both m and b. So all we have to do is plug these values into the equation y=mx+b. As a result, we get y=1x+4, which also means y=x+4

For number 35. The Correct answer is: Slope= -2/3 Y-intercept= -6

For this question I can't see all the answer choices but I know that the  Slope is -2/3  and the Y-intercept is -6. Here's why: First you need to transform the equation 2x+3y=-18 into y=mx+b format. To do this, subtract -2x from both sides of the equation and you are left with 3y=-18-2x. You can flip -18 and -2x which makes the equation 3y=-2x-18. The next step is to divide both sides of the equation by 3, which gives you y=-2/3x-6. This means Slope= -2/3 and Y-intercept= -6
