Answers

Answer 1

Answer:

Answer:

108

Step-by-step explanation:

To determine what he will save, take the amount of his paycheck and multiply by the savings rate

Savings = paycheck * savings rate

Savings = 270 * .40

Savings = 108

Answer 2

Answer:

Answer:

108

Step-by-step explanation:

40/100 = x/270

40 x 270 = 10,800

10,800 = 100x

Divide by 100

X =108

40% of 270 is 108 so

Whats the percent of change?

10 gallons to 24 gallons

Answers

the 100% is 10 gallons, so 24 is x%:
10/100 = 24/x
x = 24*100/10
x = 240
so 24 gallons is 240%, the percent change is: 240 - 100 = 140%

Change = 24-10
Percentage change = 14/10 * 100 = 140%

-- The little block on top is 6-high by 5-wide = 30 square inches.

-- The dotted line across the middle is 5 inches long.

-- The long skinny block on the bottom is (10-6)=4-high by 12-wide = 48 inches² .

-- The height of the triangle at the end is (10-6) = 4 inches.
The base of the triangle is (15 - 7 - 5) = 3 inches.
The area of the triangle is (1/2)(base)(height) = 6 inches².

-- Sum of the the 3 sections = (20 + 48 + 6) = 74 square inches.
