Answer:31/40
Step-by-step explanation:
To add you have to have a common denominator. To get that you can multiply each fraction by one in different ways. 2/5 *8/8= 16/40 and 3/8* 5/5= 15/40 and then add those two to give you 31/40.
To find the perimeter you do length + width so you do 12.4 + 5.9 to get the perimeter.
Answer:
3.2
Step-by-step explanation:
Combine like terms. 3w-3w=0. 8+2-8=2. So the answer is 2. I hope this helps!
The spoke of the wheel serves as the radius of the circle.
To solve for the circumference of the circle, we use this formula:
C = 2πr
42 inches = 2 * 3.14 * r
42 inches = 6.28 * r
42 inches / 6.28 = r
6.69 inches = r
The length of each spoke is 6.69 inches.
