First of all, you must find out how many miles it takes to go 4 hours and 8 hours.
112 ÷ 4 = 28 miles per hour
112 ÷ 8 = 14 miles per hour
So, going downstream will take 28 miles per hour and going in still water will take 14 miles per hour.
Use the formula above to find the surface area of a cylinder.
For the given cylinder the given data is the height (6mi) and diameter (16mi), use the diameter to find the radius:
Surface area:
Then, the surface area of the given cylinder is: 224π square miles
Answer:
x=1
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
x+4−3x=3x+2−3x
−2x+4=2
Step 2: Subtract 4 from both sides.
−2x+4−4=2−4
−2x=−2
Step 3: Divide both sides by -2.
-2x/-2 = -2/-2
Answer:
False the correct answer would be x^12
Step-by-step explanation:
When calculating an exponent at the power of an exponent the exponent should be multiplied. 3x4=12. The correct answer is x^12.
88,257 because 89,257-1000=88,257
