Answer:34.83
Step-by-step explanation:
4.5kwh+ 9kwh Is 13.5kwh which is how much is being used with both the freezer and a washing machine
It cost 21.5 per kWh so multiply 13.5 by 21.5 to get 290.25
To see what it would be in a year multiply 290.25 by 12(months in a year) to get 3483
Answer:
solution for your question is 10
Answer:
x = 7.6
Step-by-step explanation:
We know the opposite side and the adj side and this is a right triangle
tan theta = opp / adj
tan 66 = 17/x
x tan 66 = 17
x = 17 /tan 66
x=7.56888
To the nearest tenth
x = 7.6
I think -3; If the final par was -8, you would subtract (-4 + 2), you would get -6. Then you just divide it in half because it said he scored the same in rounds 3 and 4, leaving you with -3.
Answer:
252 minutes
Step-by-step explanation:
All lawns are the same size, so it doesn't matter the exact size of the each lawn. Ignore the 0.2 acre size.
He started the first house at 9:00 AM and the sixth house at 10:00 AM.
Read the sentence above carefully. He started the first lawn at 9:00 AM. Since he started the sixth lawn at 10:00 AM, that means he finished the fifth lawn at 10:00 AM. In 1 hour, from 9:00 AM to 10:00 AM, he did 5 lawns.
1 hour = 60 minutes
60 minutes per 5 lawns = 60/5 minutes/lawn
which can be reduced to
12 minutes per lawn
His unit rate is 12 minutes/lawn.
Now you multiply his unit rate by the number of lawns, 21 of them, to find the number of minutes to spray 21 lawns.
12 minutes/lawn * 21 lawns = 252 minutes
Answer: 252 minutes
