The length of a rectangle is 3 inches more than its width. if the perimeter is 42 inches, find the dimensions of the rectangle

Answers

Answer:

length = 12

width = 9

Step-by-step explanation:

Let w= width of rectangle

length = w + 3

2w + 2(w + 3) = 42

2w + 2w + 6 = 42

4w = 36

w = 9 ( width of rectangle)

width = 9 inches

length = 9 + 3 = 12 inches

Three times a number increased by 44 is the same as the opposite of the number. Find the number

Answers

Answer:

- 11

Step-by-step explanation:

let the number be n then 3 times the number is 3n and the opposite is - n

3n + 44 = - n ( add n to both sides )

4n + 44 = 0 ( subtract 44 from both sides )

4n = - 44 ( divide both sides by 4 )

n = - 11

The required number is - 11

Nathan lifted 13 boxes, each weighing 12 lb more than Steven's boxes. Steven lifted 15.

The total weight of Nathan's boxes would be the weight of 1 box times 13, because he lifts a total of 13 boxes.

S is the weight of Steven's boxes.

Steven's box + 12 lb = the weight of one of Nathan's boxes.

Then, you would multiply that number by 13 to get your answer.

Therefore, the first option is correct.

13(s + 12)

number of boxes Nathan lifted(Steven's weight + the extra pounds)

Hope this helped!

Answer:

13(s + 12)

Which of the following sets represents the range of money (m) that sam can make without violating either his monetary or time restriction?
A. m= {150,250}
B. m={0,150}
C. m={0,250}
D. m={100,250}

Answers

Answer: A, {150,250}

Step-by-step explanation:

In 10 hours he can do 5x2 hours work.  or 5x$50 = $250 for 5 rooms

$150 is 3x $50 or 3x2 hours work.

He can work 6 hours and make $150

or he can work 10 hours and make $250

the range he can earn so that he makes at least $150 and no more than 10 hours is$150 to $250

Use the figure below to answer the question

Solve for x

Answers

Answer:

Step-by-step explanation:

The sum of the interior angles, in degrees, of a regular polygon is given by the formula 180(n – 2), where n is the number of sides. The problem concerns a polygon with six sides, so we will let n = 6. The sum of the interior angles in this polygon would be 180(6 – 2) = 180(4) = 720. The angle on the bottom left is a right angle because of the square indicator. We know that this is 90 degrees. If we take the sum of the angles that we know we get 593. 720 - 593 = 127. x = 127.

Answer:

x=127

Step-by-step explanation:

take 180(n-2) where n=6, and you get 180(6-2) which simplified is 180(4) = 720. The sum of all the other angles is 593. subtract 593 from 720 (720-593=127). 127 is the angle of x.

all the steps laid out:

1. 180(n-2)

2. n=6

3. 180(6-2)

4. 180(4) = 720

5. 126 + 112 + 155 + 110 + 90 = 593

6. 720 - 593 = 127

7. x=127

the ratio of a shorter walkway to a longer walkway is 3 to 5. the lenght of the sorter walkway is 45 meters. what is the lenght of the longer walkway

Answers

Answer:

75 m

Step-by-step explanation:

Let s- shorter walkway, l- longer walkway.

Given:

s/l = 3/5s = 45 m

Find the length of l:

45/l = 3/5l = 45*5/3l = 75 m

Answer:

[tex]\sf\longmapsto \: length = 75 \: metres[/tex]

Step-by-step explanation:

Now let's find out what's the length of the long walkway–

[tex]\sf\longmapsto \: \frac{3}{5} = \frac{45}{\: length\: of \:longer\: walkway} [/tex]

[tex]\sf\longmapsto \: \: length\: of \:longer\: walkway= \frac{45 \times \: 5 }{3} [/tex]

[tex]\sf\longmapsto \: length\: of \:longer\: walkway= 75 \: metres[/tex]

The length of the longer walkway is [tex]\sf\longmapsto \: length = 75 \: metres[/tex]
