A new car has factory installed tires that are P205/60R16. The owner wants to a little bigger and opts for the set of P215/75R15
xenn [34]

Answer:

The car is actually moving at a speed more than 80 miles per hour

Step-by-step explanation:

Theoretically, since the speedometer of the car is at 80, it means the car is having a speed of 80 miles / hr. The car should move by a distance of 80 miles in an hour.

But, practically changing the tire size can affect the speedometer accuracy because larger tire covers more ground in each complete revolution. So, the  actual speed is higher than the speedometer reads.

<u>Example</u>

Suppose a car comes with factory-installed tires which are 21.8 inches in diameter. It means that the circumference of each tire is 68.5 inches. Now if we replace the old tires with new tires having 24.6 inches as diameter then  each new tire has a circumference of 77.3 inches. This means the car  travels almost 10 inches more with each complete revolution. This can  tremendously affect the reading on the speedometer. The speedometer  will now indicate a speed which is too slow by almost 13%. When the  speedometer reads 60 miles/hour, the car will actually be traveling at a speed of 67.7 miles/hour.

Answer:

<em>if Petra uses a scale of 1 in = 50 miles, the distance of 400 miles would fit in the page.</em>

Step-by-step explanation:

<u>Scaling</u>

Objects can be represented in a reduced or augmented size by using scaling.

Scaling is essentially multiplying or dividing by a constant factor. We use scaling when representing geographic locations on a map.

Petra has a piece of paper that is 8.5 inches wide and 11 inches long and she wants to represent a distance of 400 miles by using the scale factor of 1 inch= 20 miles.

a)

Dividing the real distance by the scale factor we get 400/20 = 20 inches. Petra would need 20 inches of paper to represent the scaled distance. That distance won't fit in any direction of the paper, so she actually cannot make the scale drawing.

b)

To make the drawing, the distance of 20 inches should fit into the page in any orientation, let's assume it's done across the paper's width of 8.5 inches.

Dividing 400 / 8,5 = 47

This gives us an idea of the appropriate scale factor. We can use a round number like 50. Thus, if Petra uses a scale of 1 in = 50 miles, the distance of 400 miles would fit in the page.

The volume of a cylindrical container
Ray Of Light [21]

Answer:

A. \frac{3}{4}\textrm{ gal}

Step-by-step explanation:

Given:

Volume of the cylindrical container before dilation, V_{i}=1\textrm{ gal}

Scale factor of the dilation, SF=\frac{3}{4}

Therefore, the volume of the dilated cylinder is given as:

V_{f}=SF\times V_{i}

Plug in 1 gal for V_{i} and \frac{3}{4} for SF. Solve for V_{f}. This gives,

V_{f}=\frac{3}{4}\times 1\\V_{f}=\frac{3}{4}\textrm{ gal}

Therefore, the volume of the dilated cylinder is \frac{3}{4} gallons.
