I think just the "possible" ones, without fully factoring, are based on factors of the last whole number-- +20.
So factors of 20: 1, 2, 4, 5, 10, 20

A new restaurant is attracting customers with searchlights has a radius of 2 feet. What is the searchlights circumference?
Assoli18 [71]

Answer:

12.56 feet

Step-by-step explanation:

The perimeter of a shape is the sum of all its side.

Since circle doesn't have "sides", the perimeter is the length of the whole circle. This has the name "circumference".

The circumference of a circle has the formula:

C=2\pi r

Where

C is the circumference (perimeter of a circle)

r is the radius

Given,

r = 2 feet

We substitute and find the circumference, using 3.14 as \pi,

C=2\pi r\\C=2(3.14) (2)\\C=12.56

Hence, the circumference is 12.56 feet

Meg lives in Indianapolis and wants to visit her mom in Lima. She has been meaning to go to a chiropractor in Dayton, so she is
ella [17]

Answer: 44 miles

WORKINGS

Given,
The distance between Indianapolis and Lima, IL = 173 miles
The distance between Indianapolis and Dayton, ID = 165 miles
The distance between Dayton and Lima, DL is unknown

Since there are straight roads connecting the three cities, the connection between them form a right angles triangle.

The right angle is at Dayton
The hypotenuse is the distance between Indianapolis and Lima, IL

Therefore IL^2 = ID^2 + DL^2
173^2 = 165^2 + DL^2
DL^2 = 173^2 – 165^2
DL^2 = 29929 – 27225
DL^2 = 2704
DL = 52 miles

Therefore, The distance between Dayton and Lima, DL = 52 miles

The question is asking how many more miles would Meg drive if she stopped in Dayton first than if she drove directly to Lima.

That is, Distance of Indianapolis to Dayton + Distance of Dayton to Lima – Direct distance of Indianapolis to Lima
That is, ID + DL – IL
= 165 miles + 52 miles – 173 miles
= 217 miles – 173 miles
= 44 miles

Therefore, Meg would drive 44 more miles if she stopped in Dayton first than if she drove directly to Lima.

Can someone help me with this question​
Contact [7]

Answer:

Very Simple!

Step-by-step explanation:

Just use the distance formula!

(I'm in a math class right now, so I have to keep it brief)

Distance Formula, example:

AB=\sqrt{(x_{1}-x_{2})^{2}+(y_{1}-y_{2})^{2} }

Just input the x and y values from A and B into here, and then that's it!

Hope this helps!

Happy Geometry!
