Combine like terms, 1+6 is 7 and 2t+4t is 6t. so 6t+7=55. get the t by itself by subtracting 7 from both sides. 6t=48, divide by 6. t=8
I think the answer is 10-11
First, we multiply the denominator to get to 9. That would be x3. We then do that to the top, and end up with the fraction 3/9, which is equivalent to 1/3.
Answer: 12.57 ft
Step-by-step explanation:
Circumference of circle with radius of 4ft.
= π * radius * 2
= 22/7 * 4 * 2
= 25.14 ft
Circumference of circle with radius of 6ft.
= 22/7 * 6 * 2
= 37.71 ft
Difference = 37.71 - 25.14
= 12.57 ft
