Answer:
Step-by-step explanation:
+ Because of a right triangle, so we can find them- the missing lengths:
+ sin(40)= GH/GF
so GH = GF * sin(40) = 88* sin (40) = 56.565= GH
+ cos( 40) = FH/GF
so FH= GF *cos(40)= 88* cos(40) = 67.412= FH
Have a good day
The first thing any good mathematician does is convert the measurements to the same unit as what the question is asking. In this problem, it states that the pool fills at a rate of 20 cubic meters per hour. Just keep in mind that an hour is 60 minutes.
The next step is to see how many cubic meters will cost $300. This can be done by dividing 300 by 10. This gets you 30 cubic meters of water.
You already know that 60 minutes is 20 cubic meters of water. That leaves the remaining 10 cubic meters of water. By dividing the rate given, you get that 30 minutes is 10 cubic meters of water. Add the 60 and 30 together to get 90 minutes.
It will take 90 minutes for the pump to use $300.
it is 100 times greater because it is two places higher than 57,080
Answer:
2×10−4
Step-by-step explanation:
To change 0.0002 to scientific notation, move the decimal to the right 4 places so that you get 2. The exponent on the base 10 will be -4 because the decimal was moved to the right 4 places
