A ratio is just making a comparison between different quantities.

example:

Say there are 10 students in a class. 4 students are girls, 6 are boys.

the ratio of girls to boys is 4:6
then you simplify to 2:3 

the ratio of boys to girls is flipped because boys is said first.
boys to girls  6:4 simplified to 3:2

If you are asked for the ratio of girls to students then it's 4:10 because you use the number of all students in the class.
4:10 simplifies to 2:5

hope this helps

lesya692 [45]

Answer:

the answer is 2.90

Step-by-step explanation:

Picture a rectangle, if one side is 3.4 then the other side 3.4. Add those two togerther gives you 6.8. Now you can subtract 6.8 from the perimeter which is 12.6 then that gives you 5.8. Then you split the 5.8 which give you 2.90 which is the length of the rectangle. So if you label all the sides of the rectangle like this 3.4 + 3.4 + 2.90 + 2.90 = 12.6

Heidi Muir, a sporting goods wholesaler, purchased goods from a supplier for $3,400. The
Lena [83]

Answer:

56.44%

Step-by-step explanation:

From the question, we have the following values

% Discount = 3%

Full allowed payment days = 30 days

Discount days = 10 days

1 year = 365 days

The formula for Effective Annual rate or Annual rate in effect =

Discount %/(1-Discount %) x (365 days/(Full allowed payment days - Discount days))

= 3%/(1 - 3%) × (365 days/30 days - 10 days)

= 0.03/(1 - 0.03) × (365/20)

= 0.03/0.97 × (365/20)

= 0.5644329897

Converting to percentage

0.5644329897 × 100

= 56.44329897%

Approximately = 56.44%

Therefore, the annual rate Heidi, in effect, is paying the supplier if she fails to pay the invoice at the end of the discount period is 56.44%
