5. Noelle always leaves a tip of between 10% and 15% for the stylist when she gets her hair done. This can be represented by the system of inequalities shown below, where y is the amount of tip
and x is the cost of the hair service. Which of the following is a true statement?
y > 0.12
y < 0.152

A. When the cost of the hair service, x, is $50 the amount of tip, y, must be between $5 and
$7.50.
B. When the tip, y, is $15, the cost of the hair service, x, must be between $50 and $75.
C. When the tip, y, is $10, the cost of the hair service, x, must be between $100 and $150.
D. When the cost of the hair service, x, is $75 the amount of tip, y, must be between $11.25
and $15.

the answer is c.

for continuous functions, they continue in the same pattern and you have to find that pattern kinda like slope

c

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
