30 min = 30/60 hr = 0.5 hr
d = rt
100 = r*0.5
100/0.5 = r
200 = r
r = 200 mph.
We know that Rate = distance/time
(30 minutes is .5 hour)
Rate=100 mile/.5 hour
Divide and we get:
Rate=200 MPH
(Hint: MPH is Miles per Hour---Per means "for each")
Make sense?
6-5 (the square root of 25) is 1, so the answer is 1/4 or 0.25
Area=pi (radius^2) Plug in numbers.
206=3.14 (r^2) Divide both sides by 3.14
65.61=r^2 Then square root both sides.
8.1ft =r Then round to the nearest foot.
r=8ft
Answer: A - 30 cubes
B - Volume of prism = feet³
Step-by-step explanation: We are given that the dimensions of the rectangualr prism is,
Length = = feet
Width = 1 foot
Height = = feet
Thus, the volume of the prism = Length × Width × Height
i.e. Volume of the prism = × 1 × = feet³
Now, the side of the cube = foot each.
Volume of the cube = = feet³
You multiply straight across, and one number is a fraction and the other is not.
