You will get 100 points I need this to check my real work that I already did! Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.

a. Show that the ratios 10/20and 30/60 form a proportion by finding a common multiplier.
b. Show that the ratios in part (a) are equal by writing them in simplest form.

  a) "common multiplier" is 3

  b) both reduce to 1/2

Step-by-step explanation:

Perhaps your "common multiplier" is 3. It multiplies both numerator and denominator in 10/20 to give you 30/60.

The simplest form of both fractions is 1/2.

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

step-by-step explanation:

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
