Given:
45 minutes
6,750,000 joules
Power(w) = Work(j) / Time(s)
Convert the time from minutes to seconds
1 minute = 60 seconds
45 minutes * 60 seconds/min = 45 * 60 seconds = 2,700 seconds
w = 6,750,000 joules / 2,700 seconds
w = 2,500 watts
The power rating of the dryer is 2,500 watts.
Answer:
40
Step-by-step explanation:
6 of 30 is the ratio 6 to 30 or 6/30.
6/30 reduces to 1/5
The survey shows that 1/5 of the students attend summer camp.
1/5 of 200 = 1/5 * 200 = 40
Answer:
5.15
Step-by-step explanation:
5.15 = 3a + 2.15
5.15 - 2.15 = 3a
3.15 = 3a
a = 0.05
I hope this helps you :)
Answer:
The number is 91
Step-by-step explanation:
Let x be the ones place digit and y be the tens place digit,
Then the number would be 10y + x,
We have,
y - x = 8
Possible values of y and x = { (8, 0), (9, 1) }
∵ 0 is not the digit of the number,
Hence, y = 9 and x = 1
Therefore, required number = 10(9) + 1 = 90 + 1 = 91
5x+2=5/2(1-2x)
5x+2=5/2-5x
2=5/2
So it is inconsistent
Hope this helps :)
