Answer:
Step-by-step explanation:
<u>Corresponding side have same ratio:</u>
- 55/121 = 5/11 (divide by 11)
- 40/88 = 5/11 (divide by 8)
- 30/66 = 5/11 (divide by 6)
The similarity ratio or the scale factor of the larger triangle to the smaller is 5/11
The sum(9) of half of the first number(1/2a) and one third of the second number(+1/3b)
That is correct
Answer:
The answer is below
Step-by-step explanation:
The diameter of a tire is 2.5 ft. a. Find the circumference of the tire. b. About how many times will the tire have to rotate to travel 1 mile?
Solution:
a) The circumference of a circle is the perimeter of the circle. The circumference of the circle is the distance around a circle, that is the arc length of the circle. The circumference of a circle is given by:
Circumference = 2π × radius; but diameter = 2 × radius. Hence:
Circumference = π * diameter.
Given that diameter of the tire = 2.5 ft:
Circumference of the tire = π * diameter = 2.5 * π = 7.85 ft
b) since the circumference of the tire is 7.85 ft, it means that 1 revolution of the tire covers a distance of 7.85 ft.
1 mile = 5280 ft
The number of rotation required to cover 1 mile (5280 ft) is:
number of rotation = ![\frac{5280\ ft}{7.85\ ft\ per\ rotation}=672\ rotations\\\\\\](https://tex.z-dn.net/?f=%5Cfrac%7B5280%5C%20ft%7D%7B7.85%5C%20ft%5C%20per%5C%20rotation%7D%3D672%5C%20rotations%5C%5C%5C%5C%5C%5C)
