30 days were sunny out of 100 days. What fraction of the days were sunny? *

3/10 of the days were sunny.

Step-by-step explanation:

We know that out of 100 days, 30 were sunny. So, we will make the fraction 30/100.

We can simplify this fraction by dividing both the numerator and the denominator by 10.

30 ÷ 10 = 3

100 ÷ 10 = 10

3/10 of the days were sunny.

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80

the revenue of the fitness center, y, is the product of two factors: the number of members and the fee paid by each member. there are 320 members now, but number of members goes down by 10 for each $5 increase in fees, so if x is the number of $5 price increases then members is equal to (320 - 10x). since the fee is currently $45, and the fee increases by $5 for every price bump x, the fee is given by (45 + 5x). so, revenue y is given by y = (320 - 10x)(45 + 5x).
