PLEASE HELP Using the digits 1 to 9 (no more than once per digit), fill in the boxes to create three equivalent ratios. _:_ _ _:_ _ _:_ _

1:9

99:11

9:11

1:99

Step-by-step explanation:

I pretty sure mb if it's wrong but Im pretty sure its right

I got 1:2 = 2:4 = 4:8

Step-by-step explanation:

You can tell that ratios are equivalent depending on whether or not they can be multiplied/divided by the same number. For instance:

1/2 multiplied by 2 is 2/4 (You can write ratios in fraction form as well)

and 2/4 divided by 2 is 1/2

Therefore, 1/2 and 2/4 are equivalent ratios!

Here's another example...

2/4 multiplied by 2 is 4/8

And with division...

4/8 divided by 2 is 2/4.

Ultimately,

1/2 times 2 is 2/4 and 2/4 times 2 is 4/8

they are all equivalent ratios!

I hope this helps :D

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
