30 treadmills to 36 elliptical machines the ratio in simplest form

1 answer:

4 0

30 treadmills : 36 ellipticals
this could be written in a few ways, but i am going to write it as a fraction. since treadmills come first, you put 30/36.

now that you have your fraction you have to find the GCF (greatest common factor) of the two numbers. the GCF is 6, so you have to divide 30 treadmills by 6, and 36 ellipticals by 6.
30/6=5
36/6=6

5/6 or 5:6 is the simplified ratio of treadmills to ellipticals

The axis of a great circle of a sphere is 24 inches. If its radius is 9 inches, how far is the plane of a section from the cente

Blababa [14]

A great circle is a section of a sphere that passes through its center. If the earth were a sphere, a great circle would be the equator and its axis would be the line connecting the geographic north and south pole. The length of the axis is then equal to the diameter of the sphere. For this problem, the radius of the sphere is 12 inches. A section is formed by slicing through the sphere and all sections of a sphere are circles. Considering the plane to be cut above and parallel with the equator (which is a great circle), the distance of the plane from the center of the sphere would then be the distance between the centers of the sphere and section. It is also given that the radius of the section is 9 inches. A right triangle is formed by connecting the center of the sphere, an edge of the section, and back to the center of the sphere whose hypotenuse is 12 inches (radius of the sphere), one leg is the 9 inches (radius of the section), and another leg is the distance of the plane from the sphere's center. Thus, the distance can be calculated using the Pythagorean theorem, d = sqrt(12^2 - 9^2) = sqrt(144 - 81) = sqrt(63) = 3*sqrt(7).

I hope my answer has come to your help. Thank you for posting your question here in Brainly.

will take 3 seconds

Step-by-step explanation:

Robber:

starts at 9

starts at 9add on 5 and you get 14

starts at 9add on 5 and you get 14add 5 more you get 19

starts at 9add on 5 and you get 14add 5 more you get 19and another 5 would give you 24

Police:

is at 0 meters

add 8 any you get 8

add 8 more and you get 16

and another 8 would get you to 24

The length of a rectangular pool is 20 feet and the width is 15 feet. The

Ray Of Light [21]

Answer:

$255

Step-by-step explanation:

As, the area of the pool bottom = length x breath

= 20 x 15 = 300 square foot

So for painting

Per square foot = $0.85

So for 300 square foot = $0.85 x 300

= $255

Bart wants to deposit his piggy bank savings into a savings account. If he deposits $325. 76, how many whole years will it take,

vladimir1956 [14]

Answer:

Step-by-step explanation:

Compounding interest :

Future value of money = Present value * (1+ r)^N

r - interest rate

n - number of period

In our example, Present value = 325.76, FV = 400, r = 2%, and we need to find N

by solving that we can find it that N is equal to 10.3675

Simple interest :

400 - 325.76 = 74.26$ we need to increase

325.76*2% = 6.5152$ each year

74.26 / 6.5152 = 11.3949

as a whole year = 12years
