Michelle simplified an expression for the perimeter of the rectangle below and got 5/6x + 35. Explain her error, and include the correct expression for the perimeter.
The width is 5/6x+23 and the Height is 12.

Answers

Answer 1

Answer:

Michelle didn't double the height and width for the perimeter and the correct expression is:

[tex]\frac{5}{3}x+70[/tex]

Step-by-step explanation:

Given

Length = l = 5/6x+23

Width = w = 12

The perimeter of a rectangle is given by:

[tex]P = 2(l+w)[/tex]

Putting the values, we get

[tex]P = 2\{(\frac{5}{6}x+23)+12\}\\\\P = 2(\frac{5}{6}x+23+12}\\P =2(\frac{5}{6}x+35)\\P = 2*\frac{5}{6} + 2* 35\\P =\frac{5}{3}x+70[/tex]

The length and width had to be doubled for the perimeter which Michelle didn't.

Hence,

Michelle didn't double the height and width for the perimeter and the correct expression is:

[tex]\frac{5}{3}x+70[/tex]

Answer 2

Answer:

Michelle didn't double the height and width for the perimeter and the correct expression is:

Step-by-step explanation:

Given

Length = l = 5/6x+23

Width = w = 12

The perimeter of a rectangle is given by:

A line that passes through the points (−5, 7) (10, 1). Using the mx+b format

Answers

Answer:

y=2x-19

Step-by-step explanation:

I'm guessing you mean slope intercept form y=mx+b

If so, first you would have to find the slope of the line

To do that, use the formula y2-y1/x2-x1

Remember you can pick any coordinate pair for this

I will pick 1=y2 -5=y1 10=x2 and 7=x1

When I put that in the equation I get 1-(-5)/10-7

Overall I get 6/3, or 2

Now to find the y intercept, you plug in the slope and one of the coordinates(any is fine)

I will pick (10,1)

1=y and 10=x and 2=m

1=2(10)+b

this simplifies to 1=20+b

now subtract 20 from both sides and get -19 = b

Now you have your equation y=2x-19

How many hours does Cesar need to practice during the rest of the week in order to have his 10 total hours?

Answers

Answer: See explanation

Step-by-step explanation:

Your question isn't really clear. Let me help you rephrase it and solve.

Let's say Cesar is creating a schedule to practice his instrument for band. He needs to practice for a total of 10 hours in a week. On Monday he practice for 1 1/2 hours, on Tuesday he practiced for 2 1/4 hours, and on Wednesday he practiced for 1 1/2 hours.

The total hours that Cesar has used in practicing will be:

= 1 1/2 + 2 1/4 + 1 1/2

= 5 1/4

To get the number of hours that Cesar need to practice during the rest of the week in order to have his 10 total hours, we subtract 5 1/4 hours from 10 hours. This will be:

= 10 - 5 1/4

= 4 3/4 hours.

Cesar needs to practice for 4 3/4 hours more.

A 3-yard roll of wrapping paper costs $13.14. What is the price per foot?​

Answers

Answer:

Step-by-step explanation:

1 yard is equal to 3 feet.

since you have 3 yards, it'll be 9 feet.

13.14/9 to get your answer

or $1.46 per foot

The price per foot of wrapping paper is $1.46.

First, we need to convert 3 yards to feet. There are 3 feet in 1 yard, so 3 yards is equal to 3 * 3 = 9 feet.

The price per foot is simply the total price divided by the number of feet. In this case, the total price is $13.14 and the number of feet is 9, so the price per foot is:

price per foot = $13.14 / 9 feet

= $1.46 per foot

Therefore, the price per foot of wrapping paper is $1.46.

m∠R is 72°

Step-by-step explanation:

In the given figure

∵ ΔPQR ≅ ΔUVW

→ From congruency

∵ m∠P = m∠U

∵ m∠Q = m∠V

m∠R = m∠W

∵ m∠R = (10x - 18)°

∵ m∠W = 8x°

∵ m∠R = m∠W

→ Equate their measures

10x - 18 = 8x

→ Add 18 to both sides

∵ 10x - 18 + 18 = 8x + 18

∴ 10x = 8x + 18

→ Subtract 8x from both sides

∴ 10x - 8x = 8x - 8x + 18

∴ 2x = 18

→ Divide both sides by 2 to find x

x = 9

→ Substitute the value of x in the m∠R

∵ m∠R = 10(9) - 18

∴ m∠R = 90 - 18

∴ m∠R = 72°

m∠R is 72°

A package that is heavier than 11 lb. and 8 oz. will have a label that says "heavy" on it. Gloria packed 6 flower pots to send to her customers. Each of the flower pots weighs 1 lb. and 12 oz. The packing material weighs 5 oz. Will her package be labeled as "heavy"?

Answers

Answer:

No, the package will not be labeled "heavy"

Step-by-step explanation:

1) if you multiply 1lb. and 12 oz. by the number of flower pots(I'll be using the variable P), then the expression will be (1lb.P) (12oz.P).

2) then after you get the answer for that, which is 6lb. 72oz. and after that you'll have to add the weight of the packaging, which is 5oz. which the answer is 6lb. 77oz.

3) after, you will then have to get the number of pounds from the ounces if there are more than 16, which there are, so after you get the answer out of that, which is 4 and then you would have 13oz. leftover.

4) you would then have to add your 4lb. to your 6 that you already have, which would be 10lb.

Final) so in the end, you would have 10lb. 13oz.

, find the length of QS and TV.

Answers

The length of the segment QS is 8 units and the length of the segment TV is 8 units and this can be determined by using similar triangle properties.

Given :

Triangle QRS is congruent to triangle TUV.The length of the segment QS is (3v + 2).The length of the segment TV is (7v - 6).

The following steps can be used in order to determine the length of QS and TV:

Step 1 - According to the given data, the triangle QRS is congruent to triangle TUV.

Step 2 - So, the length of the segment QS is equal to the length of the segment TV.

QS = TV

Step 3 - Substitute the values of QS and TV in the above expression.

3v + 2 = 7v - 6

7v - 3v = 6 + 2

4v = 8

v = 2

Step 4 - The length of the segment QS and TV is:

QS = 3(2) + 2 = 6 + 2

QS = 8

TV = 7(2) - 6 = 14 - 6

TV = 8
