A. yes it would be a function of x because they change exponentially. the exponent is -3. -3 as an exponent is the same as cube root.
y = x^-3
2 = 8^-3
3 = 27^-3
And so on

well f (100) just means to substitute 100 any place there is an x so
f (100) = 10 + 20 (100)
f (100) = 2010

since x is the amount of hours f (100) represents the cost when a bike was rented for 100 hours.

The ratio of boys to girl in a school is 5:7 if there are 600 students, how many girls are there

larisa86 [58]

Answer:

350 girls

Step-by-step explanation:

So,

The secret to solving problems with ratios is to find the value of one unit.

5:7 = 12 units total

To find one unit, divide the total number of students by the total number of units.

600/12 = a

Simplify

50/1 = a

50 = a

The value of each unit is 50.

Now, multiply the units by the numbers in the ratio.

50(5) = b

250 = boys

50(7) = x

350 = x

There are 350 girls.
