Question 15 (5 points)
The perimeter of a rectangle is 38 units. The length is 13 units longer than the width.
What are the dimensions of the rectangle?
OA) 12 by 7
B) 18 by 5
C) 15 by 4
D) 16 by 3
help

Answers

Answer:

Step-by-step explanation:

Width =  w units

Length = ( w + 13 ) units

Perimeter of rectangle = 38 units

2* (length + width) = 38

2*(w +13 + w )= 38            {Use distributive property: a*(b+c)=(a*b) +(a*c)

2* ( 2w + 13)   = 38  

2*2w + 2*13   = 38

     4w + 26   = 38              {Subtract 26 from both sides}

              4w   = 38 - 26

              4w =  12       {Divide both sides by 4}

                w = 12/4

w = 3 units

Length = 3 + 13 = 16 units

the answer is c because if you don't know the answer and you want to guess the best answer would be c always for guessing

Answer:

x=3

Step-by-step explanation:

Hello There!

The shown angles have a sum of 90 degrees

This is noticeable because there is a square at the vertex which indicates that its a right angle

A right angle has a measure of 90 degrees

That being said we can create an equation to solve for x

90 = 66 + 8x having made an equation we now solve for x

step 1 subtract 66 from each side

90 - 66 = 24

66 - 66 cancels out

now we have

24 = 8x

step 2 divide each side by 8

8x/8=x

24/8=3

we're left with x = 3

Answer:

x=3

Step-by-step explanation:

8x+66=90 complement

8x=90-66

x=24/8=3

Answers

Answer: 6480

Step-by-step explanation: So since the dimensions are easy to calculate, just multiply 9 by 4 and 15 by 3, then you get 36 and 45. Multiply 36 by 45 and you get 1620, but since the vacuum can get 2 square ft, then divide by 2 and you get 810. Since it takes 8 minutes to clean up, multiply 810 by 8 and you get 6480. I do believe

After a very successful year, Cheap-Rentals raised salaries by a scale factor of `\frac{11}{10\ }`. If Luan now makes $14.30 per hour, what did she make before?

Answers

Answer:

$13

Step-by-step explanation:

Given that :

Increase in salary factor = 11/10

New salary = $14.30

Initial salary = x

To obtain the value of the initial salary,

The product of the scale factor by the initial salary sgiuf give the amoi tof the new salary

11 / 10 * x = 14.30

1.1x = 14.30

x = 14.30 / 1.1

x = $13

Hence.initial salary per hour = $13

10) A circle has center at (-5, 3) and passes through the point (-1, 3).
a) Give the radius of the circle.

b) Give the equation of the circle described.

Answers

a) radius= 4 units

b) (x+5)^2+(y-3)^2=4^2

The distance between the x values in the center point and a point included in the graph will give you the radius.
The x values are 4 units apart (-5 to -1) so your radius is 4 units

Circle formula:
(x-h)^2+(y-k)^2=r^2
Where (h,k) is the center point and r is the radius

Replace h with -5, k with 3, and r with 4 to get equation listed in answer above
