Savannah and sarah are planning on riding their bikes to a point located 1100 feet from their house. Their bicycle tires have a diameter of 26 inches. How many revoloutions will their tires make on the path from their house to the park

162 revolutions.

Step-by-step explanation:

Given:

Savannah and Sarah are planning on riding their bikes to a point located 1100 feet from their house.

Their bicycle tires have a diameter of 26 inches.

Question asked:

How many revolutions will their tires make on the path from their house to the park ?

Solution:

To calculate the number of revolutions their tires made, we will first calculate distance traveled by their tire in one revolution by using circumference of circle formula:-

Diameter = 26 inches

Radius,r =

Convert 1100 feet into inches.

1 feet = 12 inch

1100 feet = 12 1100 = 13200 inches

Now, by unitary method:

81.71 inches traveled by tires in = 1 revolution

1 inches traveled by tires in =

13200 inches traveled by tires in =

Thus, total of about 162 revolutions their tires will take from their house to the park.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
