I will make u brainliest if u help me with these questions and u answer them correctly. 1. There are 14 boys and 15 girls in the school jazz band. Find the ratio of the number of girls in the band to the total number of students in the band.
2. What is 25% of 80?
3. Which of the following is the best definition of a unit rate?
A. A unit rate is two ratios that have the same value.
B. A unit rate is a rate that has a denominator of one unit.
C. A unit rate is a ratio of two quantities that have different units.
D. A unit rate is something that uses division to compare two numbers.

1) the ratio is 15: 29    2) 25% of 80 = 20   3) C

Step-by-step explanation:

Two ratios are equivalent if they represent the same number. A rate is a special ratio that compares two quantities that have different units of measure. If the second term in a rate is 1, the ratio is called a unit rate. Unit rates are often described as a quantity per unit of time or per item.

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.

answer:   (s+1)(s+4)

step-by-step explanation:

factor s2+5s+4

s2+5s+4

=(s+1)(s+4)
