Find the perimeter of the figure.
7 mi
7 mi

Answers

Answer:

28mi

Step-by-step explanation:

The perimeter of a figure is the total length of its outline, so a sum of all its lengths.

In the diagram we are given two of them, both 7, but not the other two.

Luckily these can be easily worked out.

Since this is a square figure (all angles 90-degrees), all parallel sides will be exactly equal in length. This means both of the unknown sides are 7mi long as well. This means the total perimeter is the sum of all four sides, each of which are 7mi.

7+7+7+7 (OR 4x7) = 28 mi

Hope this helped!

Answer:

The perimeter of the figure is 28 mi

Step-by-step explanation:

Perimeter of a Square

Given a square shape of side length A, the perimeter can be found using the expression below:

P = 4*A

Recall the perimeter is the sum of all the side lengths.

Since the figure shows a square with side length A=7 mi, the perimeter is:

P = 4 * 7 mi = 28 mi

The perimeter of the figure is 28 mi

2
i
n
: 15 feet. What would the width of the stage be in the scaled drawing?



Answer as a decimal.

Answers

Answer:

0.6 in

Step-by-step explanation:

Scale of drawing = ½ inch to 15 ft (½ in : 15 ft)

That is, ratio of the width on paper to actual width.

Given an actual width of 18 ft, the width of the stage on paper can be calculated as shown below:

½ in : 15 ft = x in : 18 ft

[tex] \frac{\frac{1}{2}}{15} = \frac{x}{18} [/tex]

[tex] \frac{1}{2}*\frac{1}{15} = \frac{x}{18} [/tex]

[tex] \frac{1*1}{2*15} = \frac{x}{18} [/tex]

[tex] \frac{1}{30} = \frac{x}{18} [/tex]

Cross multiply

[tex] 30*x = 18*1 [/tex]

[tex] 30x = 18 [/tex]

Divide both sides by 30

[tex] \frac{30x}{30} = \frac{18}{30} [/tex]

[tex] x = \frac{18}{30} = \frac{6}{10} [/tex]

[tex] x = 0.6 [/tex]

Width of the stage in scale drawing = 0.6 in

What is unit conversion?

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure. Unit conversion is the process of changing a quantity's measurement between different units, frequently using multiplicative conversion factors.

Given that Dominique has $13.75 in her piggy bank. All of the money is quarters.

The number of the quarters will be calculated as:-

1 dollar ⇒ 4 quarters

13.75 dollars ⇒ 13.75 x 4 quarters

13.75 dollars ⇒ 55 Quarters

Therefore, the number of quarters in the piggy bag will be 55.
