What is the area of a trapezoid that has the bases of 1 1/4ft and 14 inches and a height of 3 inches.
Rom4ik [11]

The area of the trapezoid is 43.5 inches²

Step-by-step explanation:

The formula of the area of a trapezoid is A=\frac{1}{2}(b_{1}+b_{2})h , where:

  • b_{1} and b_{2} are the two parallel bases
  • h is its height

∵ b_{1} = 1\frac{1}{4} feet

∵ b_{2} = 14 inches

∵ h = 3 inches

- Change the length of b_{1} from feet to inches

∵ 1 foot = 12 inches

∴ 1\frac{1}{4} feet = 1\frac{1}{4} × 12 = 15 inches

∴ b_{1} = 15 inches

Substitute the values of b_{1} , b_{2} and h in the

formula of the area

∴ A=\frac{1}{2}(15+14)(3)

∴ A = 43.5 inches²

The area of the trapezoid is 43.5 inches²

Marine fuel is a combination of gasoline and motor oil. The standard gasoline and oil mixture is about 98% gasoline and about 2%
Georgia [21]

Answer:

0.98g+ 0.02m= 7.1224 gallons standard mixture

0.96g+ 0.04m= 6.25 gallons break oil

3.92 gallons of gasoline  is required for  4 gallons the standard mixture

Step-by-step explanation:

If we have to use 6 gallons of gasoline this means that 98%= 6 gallons and 2% would be 6/98*2

Gasoline: Motor oil

6              :    x

98        : 2

Using the product rule

x= 6*2/98= 0.1224 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the standard oil the equation would be

0.98g+ 0.02m= 7.1224 gallons standard mixture

For break in oil

Gasoline: Motor oil

6              :    x

96        : 4

Using the product rule

x= 6*4/96= 0.25 gallons of motor oil is required.

Let the gasoline be represented by g and motor oil by m then for the break oil the equation would be

0.96g+ 0.04m= 6.25 gallons break oil

Part b. For  4 gallons of the "break in" mixture

96% of the 4 gallons of the "break in" mixture is gasoline =  3.84 gallons of gasoline

4% of 4 = 0.16 gallons of motor oil

Now the standard mixture 4 gallons would contain 98 % of gasoline and 2 % of motor oil

98% of 4 gallons= 3.92 gallons of gasoline

2% of  4 gallons= 0.08 gallons of motor oil.
