to make a shade of lavender paint jon mixes 4 ounces of red tint and 28 ounces of blue tint into one gallon of white paint. if 20 gallons of white paint and 80 ounces of red tint are used, how much blue tint should be added?

Answer:

A) 7%

Step-by-step explanation:

There are 360 degrees in a circle.  Thus, a 25 degree sector would make up 25/360 of the circle.  25/360 can be simplified to .06944444.  This rounds to .07, which is 7%.

Answer:

A. 7%

Step-by-step explanation:

A percent can be found by dividing the part by the whole and multiplying by 100.

(part/whole) *100

There are a total of 360 degrees in a circle. This is the whole.

We want to find what percent a 25 degree angle will take up. This is the part.

(25/360) * 100

First, divide 25 by 360.

0.0694444444 * 100

Now, multiply the numbers together  

6.94444444 %

Round to the nearest whole number. The 9 in the tenth place tells us to round the 6 to a 7.

7 %

Therefore, the answer is A. 7%

Answer:

$33.46

Step-by-step explanation:

To find the cost after a 6% tax and a 15% tip, we need to multiply the amount by these two percents. Add the percents together to make the math easier.

$27.65 x 0.21 = $5.81

Now, add that number to the original cost to get the answer

$27.65 + $5.81 = $33.46

The cost of a $27.65 bill after a 6% and 15% tip is $33.46
