If a bicycle wheel has a diameter of 28 inches how many revolutions does it take to travel 3 miles

Mathematics
1 answer:
KatRina [158]3 years ago
8 0
The circumference of the tire would be: 28 x PI = 87.96 inches = 88 inches.

88 inches / 12 inches = 7.33 feet

Every revolution the tire would travel 7.33 feet.

1 mile = 5,280 feet

3 miles = 5280 x 3 = 15,840 feet total.

Divide total feet by the circumference of the tire:

15,840 / 7.33 = 2,161 revolutions.

How do you implicitly differentiate: sqrt(xy)=x^2y+1
Furkat [3]
Implicit expression refers to equation that are not strictly expressed in terms of y and x separately. In this case, the derivative of expression 
<span>sqrt(xy)=x^2y+1 is

sqrt x * 0.5 y ^-0.5 dy + </span>sqrt y<span> * 0.5 x ^-0.5 dx= x^2 dy + 2xy dx 
dy (x^2 - 0.5 (</span>x/y) ^0.5) = dx (2xy  - 0.5 (y<span>/x)^0.5) 
dy/dx = </span>(2xy  - 0.5 (y/x)^0.5) / (x^2 - 0.5 (<span>x/y) ^0.5)</span>

The 45°- 45° - 90° Triangle Theorem states that the length of the hypotenuse is ________ times the length of one leg.
Airida [17]
 <span>This is an isosceles triangle. If each side is 1, we can find the hypotenuse using the Pythagorean theorem. 

a^2 + b^2 = c^2 
1^2 + 1^2 = c^2 
1 + 1 = c^2 
2 = c^2 
root 2 = c 

Thus, the answer is root 2.

Hope this helps :)</span>
