0,8 = 8/10 = 4/5 = 16/20...
Answer:
80%
Step-by-step explanation:
Total boxes of apples delivered = 90
Total boxes sold = 72
What percentage of the delivered apples have been sold?
Percentage sold = Total boxes sold / total boxes delivered × 100
= 72 / 90 × 100
= 0.8 × 100
= 80%
The percentage of the delivered apples have been sold is 80%
Percentage unsold = (total boxes delivered - total boxes sold) / total boxes delivered × 100
= (90 - 72) / 90 × 100
= 18 / 90 × 100
= 0.2 × 100
= 20%
Using a proportional relationship, it is found that the two equations that have the same constant of proportionality are givn by:
с 1 and 3
<h3>What is a proportional relationship?</h3>
A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
In this problem, the functions and constants are given as follows:
- 3. 8y = 6x -> k = 6/8 = 3/4.
Equations 1 and 3 have the same constants, hence option c is correct.

Answer:
12 in = r
Step-by-step explanation:
c = 2 π r
75 = 2 π r
75 = 6.28 r
12 in = r
So you're looking for 2 numbers you can divide to get ABOUT 4.1. This means you're going to estimate. First you can estimate that 4.1 is about 4 and then think what two numbers divide to give you 4? 8÷2 = 4 ... so now we can change it slightly to make the quotient a little higher and say
8.1÷2 = 4.05 That will round to 4.1 so you could say two numbers who's quotient is ABOUT 4.1 would be...
8.1 and 2
