Ans: 1.1 miles more
Speed = distance/time
Time is 1/5 of an hour
1/5 of 1hr = 1/5 or 0.2 hrs
Speed = 16 mph
So, we're after distance.
Distance = speed x time
= 16mph x 0.2
= 3.2 miles
Walks for 3/7 hour at 5 miles per hour :
Time & speed given, distance is what we're after.
(3/7 of 1hr is 3/7)
Distance = speed x time
= 5mph x 3/7
= 15/7 miles or 2.14285...miles
So, distance is about 2.1 miles to 1 d.p
Thus, 3.2 - 2.142... (the full ans) = 1.057... miles
Well, he biked 1.06 miles or 1.1 miles (depending on how you want to round it) more than walking.
Hope this helps!
Answer:
$22,968
Step-by-step explanation:
To solve this question, we need to find the volume of the cylinder. Let’s call this V
Mathematically V = πr2h
where r = 3m , h = 7m and π = 22/7
Putting this in the formula:
V = 22/7 * 3 * 3 * 7 = 198 cubic meter
We are told concrete costs $116 per cubic meter. Hence, for 198 cubic meter we have 198 * 116 = $22,968

you always move the decimal twice
Answer:
ma'am that screen is black ⚫
So this box will probably be very flat. Draw it out. There would be 4 surfaces with the surface area of 0.25*38. Which equals 9.5. Multiply that by 4 and it's 38. Now take the bigger surfaces. They will be 38 squared, which is 1444. Multiply that by 2, because there are 2 of those surfaces, and you get 2888. To get the total you add them up: 38+2888=2926. So the answer is 2926 meters squared.
P.S: I copied this answer from the answer I gave to someone else, because they asked the same question.
