12 gallons of water fill a tank to 3/4 capicity. What is the capicity of the tank? If the tank is then filled to capicity, how many half-gallons bottles can be filled with the water in the tank?

Answers

Answer:

The total capacity of the tank = 16 gallons

32 bottles can be filled with the water in the tank.

Step-by-step explanation:

Let the total capacity of the tank = K gallons

Now here, according to the question

3/4 capacity of the tank = 12 gallons

⇒ $(3)/(4) * K = 12\norK = 12 * (4)/(3)$

or, K = 16 Gallons

So, the total capacity of the tank is 16 gallons.

Now, capacity of 1 bottle = 0.5 gallon= (1/2) gallon

So, number of bottles filled = Capacity of each bottle x Total capacity of tank

n = 0.5 gallon x 16 gallons = 32 bottles

Hence, 32 bottles can be filled with the water in the tank.

Shinya went to the salon. The cost if her haircut was $16.00. He tipped the barber 15%. What was the total cost?

Answers

total cost=costofhaircut+tip
tip=costofhaircut times percent tip
percent tip=15%

percent means parts out of 100
15%=15/100=0.15

cost of haircut=16
tip=16 times 0.15=2.4

total cost=16+2.4=18.4

total cost=$18.40

$18.40 because 15% of 16.00 is 2.40 so 16.00 + 2.40 = 18.40.
