Angelina_Jolie [31]

Answer:

3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .

Step-by-step explanation:

Formula

$Percentage = \frac{Part\ value\times 100}{Total\ values}$

First Part

As given

Total value = $375

Part value = $ 11.25

Put values in the formula

$Percentage = \frac{11.25\times 100}{375}$

$Percentage = \frac{1125}{375}$

Percentage = 3 %

Second Part

Total value = $56.25

Part value = $11.25

Put the values in the formula

$Percentage = \frac{11.25\times 100}{56.25}$

$Percentage = \frac{1125}{56.25}$

Percentage = 20%

Therefore 3%percent of $375 is $11.25 and 20% of $56.25 is $11.25 .

The figure shows a gas tank in the form of a rectangular prism that is 40% full. How many more gallons of gas will it take to fi

Ira Lisetskai [31]

Answer:

10.8 gallons

Step-by-step explanation:

First change everything to inches:

2.75 ft = 33 in

1.5 ft = 18 in

Volume of tank = lwh = (33)(18)(7) = 4158 in³

The tank is 40% full, so only 60% is need to fill it. To find 60%, multiply 4158 by 0.6 = 2494.8 in³

Now find out how much 2494.8 in³ is in gallons:

231 in³ = 1 gallon

1 in³ = 1/231 gallons

2494.8 = (1/231)(2494.8) gallons = 10.8 gallons
