The length of a rectangle is 12 in. and the perimeter is 56 in. Find the width of the rectangle. A. 16 in. B. 22 in. C. 32 in. D. 21 in.

The answer is a. 16in 

If you add 12 that will give you 24.
Then you subtract 24 from 56 which give you 32.
Then you would divide 32 by 2 
And that will give you 16

Tracy needs to find the length and width of the equipment storage room where she works. the room is 3 meters longer than it is wide. Its perimeter is 18 meters. Find the width in meters.

Perimeter = 2 · width + 2· lenght
W = L - 3
18 = 2 · ( L - 3) + 2 · L
18 = 2 L - 6 + 2 L
18 + 6 = 4 L
24 = 4 L
L = 24 : 4 = 6 m
W = 6 - 3 = 3 m
The width is 3 m.

A rectangle has a length of 10 ft. and a width of 6 ft. what's the perimeter? a. 60 ft. b. 16 ft. c. 32 ft. d. 26 ft.

Answer:  The required perimeter of the rectangle is 32 ft.

Step-by-step explanation:  Given that a rectangle has a length of 10 ft. and a width of 6 ft.

We are to find the perimeter of the rectangle.

We know that

the perimeter of a rectangle with length l units and width w units is given by

P=2(l+w).

For the given rectangle, we have

length, l = 10 ft.  and  width, w = 6 ft.

Therefore, the perimeter of the rectangle is

P=2(l+w)=2(10+6)=2\times16=32.

Thus, the required perimeter of the rectangle is 32 ft.

Dana wants to make two types of dog treats. she has 10 cups of peanut butter and 12 cups of flour. her dog bone treat recipe uses 3 cups of peanut butter and 2 cups of flour to make one tray. a tray of her oatmeal dog treat recipe uses 1 cup of peanut butter and 4 cups of flour. she plans to sell trays of dog treats at the town festival and charge $6 for a tray of dog bone treats and $7 for a tray of oatmeal treats. dana wants to maximize her income from selling the dog treats.when writing constraints for the problem, what is the most reasonable definition for the variables x and y?

Constraints: 
10 cups of peanut butter ⇒ x < 10
12 cups of flour ⇒ y < 12

dog bone treat : 3x + 2y ; price : 6 per tray
oatmeal dog treat : x + 4y ; price : 7 per tray

dog bone treat: 3(3x + 2y) = 9x + 6y
oatmeal dog treat: 1(x+4y) =  x + 4y
                                                  10y+ 10y

3 x 6 =18
1 x 7 =  7
            25

variable x is the peanut butter. It should not exceed the 10 cups of peanut butter.
variable y is the flour. It should not exceed the 12 cups of flour.

QUESTION POSTED AT 25/01/2020 - 01:44 PM

∆ABC is similar to ∆DEF. The ratio of the perimeter of ∆ABC to the perimeter of ∆DEF is 1 : 10. The longest side of ∆DEF measures 40 units. The length of the longest side of ∆ABC is ____units. The ratio of the area of ∆ABC to the area of ∆DEF is ____.


we know that


1) scale factor is equal to  \frac{1}{10}


2) The ratio of the perimeters of the triangles is equal to the ratio of the measures of the sides


3) the longest side of ∆ABC=[scale factor]*the longest side of ∆DEF

the longest side of ∆ABC= \frac{1}{10}*40

the longest side of ∆ABC= 4 units


the answer part a) is

the longest side of ∆ABC is  4 units


Part b)

The ratio of the area of ∆ABC to the area of ∆DEF is equal to the scale factor squared

so

 [scale factor]^{2} =(\frac{1}{10})^{2} \\ \\ =\frac{1}{100} \\ \\ =0.01


therefore


the answer part b) is

The ratio of the area of ∆ABC to the area of ∆DEF is  \frac{1}{100}

The perimeter (P) of the rectangle is the sum of twice is length (L) and twice its width (W), 
                                       P = 2L + 2W
Substituting the known values, with either of the givens being length and width,
                                      P = 2 x 84 ft + 2 x 50 ft = 268 ft

Thus, the answer is letter A. 268 feet.

One dimension of a rectangular map is 8 inches and the perimeter is 40 inches. What is the other dimension of the map?

In a rectangular figure, the opposite sides should be equal. If one of the sides measures 8 inches, the side opposite to this should also be 8 inches. We let x be the other dimension. The perimeter (P) is equal to, 
                                     P = 2 x 8 + 2x
Substituting the known values, 
                                       40 in = 16 + 2x
Solving for x gives an answer of 12 in. Thus, the other dimension is 12 inches.

Find the dimensions of the rectangle with area 289 square inches that has minimum perimeter, and then find the minimum perimeter.

 To minimize the perimeter you should always have a square. 
sqrt(289) = 17 
The dimensions should be 17 X 17 

To see , try starting at length 1, and gradually increase the length. 
The height decreases at a faster rate than the length increases, up until you reach a square. 

Or if you want to use algebra, Say the width is 17-x 
Then the length is 289/(17-x) 

Now, this is bigger than 17+x, as shown here: 
289/(17-x) > 17+x 
289 > 289 - x^2 
which is true. 
so the perimeter would be bigger than 2 * (17- x + 17 + x) = 2 * (2 * 17) = 4 * 17 

Again, the dimensions should be a square. 17 X 17.

An equilateral triangle has a perimeter of 15x3 33x5 feet. what is the length of each side?

Answer:

5x^3+11x^5 feet.

Step-by-step explanation:

We have been given that an equilateral triangle has a perimeter of 15x^3+33x^5 feet. We are asked to find the length of each side of the triangle.

Since we know that all sides of an equilateral triangle are of equal measure and the perimeter of an equilateral triangle is three times its each side length.

To find the length of each side of our given triangle, we will divide our given perimeter by 3.

\text{Length of each side of triangle}=\frac{15x^3+33x^5}{3}

\text{Length of each side of triangle}=5x^3+11x^5

Therefore, the length of each side of our given triangle is 5x^3+11x^5 feet.
