Answer:

111.76 cm

Step-by-step explanation:

The formula for the perimeter of a triangle is given as:

Side A + Side B + Side C

Since our final answer is going to be in centimeters we have to convert the sides from inches to centimeters

Hence:

1 inch ~ 2.54 centimeters

For 12 inches

1 inch = 2.54 cm

12 inches = x

Cross Multiply

x = 12× 2.54 cm

x = 30.48 cm

For 14 inches

1 inch = 2.54 cm

14 inches = x

Cross Multiply

x = 14× 2.54 cm

x = 35.56 cm

For 18 inches

1 inch = 2.54 cm

18 inches = x

Cross Multiply

x = 18× 2.54 cm

x = 45.72 cm

Hence, the perimeter of the triangle

= 30.48 cm + 35.56 cm + 45.72 cm

= 111.76 cm

Step-by-step explanation:

Form a table as below;

<u>Interval         Frequency{f}      Midpoint of frequency{x}          fx    </u>

1-7                    19                         4                                            76

8-10                  14                         9                                            126

11-15                  15                         13                                           195

16-20                20                        18                                           360

21-35                 10                        28                                          280

36-50                13                         43                                          559

Sum                   91                                                                        1596

The mean  of grouped data = Sum of { Interval Midpoint * Frequency } /Sum of frequency

The mean= 1596 / 91

The mean = 17.54

The United States is about the only country that still uses the units feet, miles, and gallons. However, you might see some car
Black_prince [1.1K]

Answer: 4.5 \text{ miles per gallon}

Step-by-step explanation:

Given :  The fuel efficiency of car = 7.6 km per kilogram

We also given that

1 mile = 1.609 km

Then, \text{1 km}=\dfrac{1}{0.609}\text{ mile}

1 gallon = 3.785 liters

\text{1 liter}=\dfrac{1}{3.785}\text{ gallon}

1 liter of gasoline = 0.729 kg

Then, \text{1 kg}=\dfrac{1}{0.729}\text{ liter}

\Rightarrow\ \text{1 kg}=\dfrac{1}{0.729}\times\dfrac{1}{3.785}\text{gallon}

Now, the fuel efficiency of car will be :

7.6\times\dfrac{1}{0.729}\times\dfrac{1}{3.785}\times\dfrac{1}{0.609}\\\\=4.52275317827\approx4.5 \text{ miles per gallon}

Hence,  the car’s fuel efficiency in miles per gallon= 4.5
