So distance=rate x time and if we rearrange this to find the time we get time=distance/rate. Now we can just plug in the numbers.
3.54*10^7/3*10^8=time(seconds)
To solve this we can just divide the parts of the scientific notation separately.
3.54/3=1.18
10^7/10^8=1/10
Now we just multiply our answers together because we separated them before we divided.
1.18*1/10=.118
So the answer is .118 seconds
Answer:
B. 12 slats
Step-by-step explanation:
Divide 42 by 3.5 and you get 12.
Answer:
18.86 feet
Step-by-step explanation:
One rotation of the tire is equal to the circumference of the tire
The formula for circumference of a circle (remember that a tire is shaped as a circle) = πd
where
π = 22/7
d = diameter
The size of one revolution = 2 x 22/7 = 44/7 feet
The distance covered in one rotation of the tire is 44/7 feet
The distance covered in 3 rotations = (44/7) x 3 = 18.86 feet
Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
