The value of the scale factor k, is 1.5

<h3>Perimeter</h3>

The perimeter of a shape is the sum of the side lengths of the shape

<h3>Dimensions </h3>

The dimensions of the triangle MNO are given as:

MN = 5

NO = 4

OM = 2.5

Calculate the perimeter of the triangle as follows:

MNO=5 + 4 +2.5

MNO=11.5

Divide 17.25 by 11.5 to calculate the scale factor (k)

k = \frac{17.25}{11.5}

k = 1.5

Hence, the scale factor is 1.5

fenix001 [56]
Greetings!

This can be solved by creating a simple equation.
1/4+1/6+x=1

Solve for x.
1/4+1/6+x=1
Find the LCM.
3/12+2/12+x=1
5/12+x=1
Add -5/12 to both sides.
(5/12+x)+(-5/12)=(1)+(-5/12)
Simplify.
x=1/1-5/12
Find the LCM.
x=12/12-5/12
x=7/12

He kept 7/12 of the raisins for himself.

Hope this helps.

A rectangular garden has dimensions of 100 feet by 10 feet. Next season, the garden is decreased to 2/5 of its size. What is the
mina [271]

Answer:

40 feet by 4 feet

Step-by-step explanation:

Given length (l) = 100 feet

width (w) = 10 feet

As mentioned in the question the size of garden is decreased to 2/5 of its size. <u>It will effect the length and width with the same proportion.</u>

So,

New length = 100 * 2/5 = 40 feet

New width  = 10 * 2/5 = 4 feet

Therefore, the scale of new drawing would be 40 feet by 4 feet

Elainas old bicycle had tires with a 12-inch diameter her new bicycle had tires with a 16-inch diameter what is the difference i
mr Goodwill [35]

Answer:

The difference between the circumference of the tires is 12.56 inches.

Step-by-step explanation:

Given:

Diameter of old bicycle tires = 12 inch

Diameter of new bicycle tires = 16 inch

We need to find the difference in circumference of the tires.

Solution:

First we will find the circumference of Old bicycle tires.

Circumference can be calculated by π times diameter.

Circumference of Old bicycle tire = \pi \times 12 = 37.68\ in

Now we will find the circumference of new bicycle tire.

Circumference of New bicycle tire = \pi \times 16 = 50.24\ in

Now to find the difference between the circumference of the tires we will subtract Circumference of New bicycle tire from Circumference of Old bicycle tire we get;

framing in equation form we get;

difference between the circumference of the tires = 50.24-37.68 =12.56\ in

Hence The difference between the circumference of the tires is 12.56 inches.
