Answer:
25% of<em> 200 </em>is 50
Step-by-step explanation:
25% + 25% + 25% + 25%=100%
This also equals
50 + 50 + 50 + 50 = 100%
Now add those
50 + 50 + 50 + 50 = 200
So 25% of 200 is 50.

Step-by-step explanation:
Givens
r = 5
h = 30
Formula
SA = 2*pi*r^2 + 2pi*r*h
Solution
SA = 2*3.14 *5^2 + 2*3.14 * 5* 30
SA = 50*3.14 + 300*3.14
SA = 157 + 942
SA = 1099 square inches.
Answer:
4 miles per hour.
Step-by-step explanation:
2 hours = 28 miles downstream; 14 miles per hour
3 hours = 18 miles upstream; 6 miles per hour
The boat went faster when going downstream meaning the current is going towards up stream. I would find the average speed, (14+6=20/2=10 m/h average) and determine subtract the average from the speed from wither upstream or downstream. 14- 10= 4 and 10- 6= 4. Therefore the stream's current is 4 miles per hour.
Answer:
Without math, how would we know how to count seconds minutes, etc.?
Math is extremely important for knowing how to do simple things like cooking, you need to know for how much time to put something in the oven or microwave or stove. Those are just the basics. There is a lot more stuff out there that math is used for.
