in kurt's school, the ratio of boys to girls is 4/3. of 120 students are boys, how many students are girls?

90 of the students are girls.

Step-by-step explanation:

Boys : Girls

B : G

4 : 3

120 : ?

(120 ÷ 4 = 30) so 4 × 30 = 120

(Do this to the other side) 3 × 30 = 90

B : G

120 : 90 [90 girls out of 210 total students]

Hope this helps. :)

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
