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

162 revs

Step-by-step explanation:

-The distance to be covered is 1100 ft.

-The circumference of  the tire is equivalent to the distance covered by the tire in one revolution.

#We find the tire's circumference in feet(1inch=0.08333)

We then divide the distance to be traveled by the tire's circumference to determine the number of revolutions made:

Hence, the tire makes approximately 162 revs.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).
