Hello!
First of all we will need to find the circumference, as it is the distance around the wheel. We will use 3.14 for pi.
42(3.14)=131.88
Now we multiply by three to see how far they go in a minute.
131.88(3)=395.64
Now we multiply by 5 to see five minutes.
395.64(5)=1974.2
A passenger will travel approximately 1978.2 feet in 5 minutes.
I hope this helps!
Answer:
12 is the rate
Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
1. add all the beads up together:
20+10+30= 60
2. add the blue and yellow beads up:
10+30= 40
3. put 40 over 60
40/60 which equals 2/3
4. the final answer:
2/3
Answer: +/- 7
Step-by-step explanation:
3x² = 147
To solve for x divide through by three first.
3x² = 147
x² = 49, now we take the square root of both side by trying to apply laws of indices.
√x² = √49
The square root will neutralize the effect of the square because
√a = a¹/² so (x²)¹/², and (x²)¹/² =
x²×¹/² = x, therefore the solution is
x = +/- 7.
Answer:
5 and -5
Step-by-step explanation:
3x² = 75
x² = 75/3
x² = √25
x = 5 and - 5
