Ok so we have 7:00 pm and she spends 12 more hours over.
Now lets count up 12 hours
=19
You could also just do 7+12! :)
So therefore, she spend 19 hours had her friends house! :D
Hope this helps!
Yes! All the domain (or x numbers) are increasing by 1. All the range (or y numbers) are increasing my 3 each time. If you were to put it on a graph, you would see the line straight and increasing in a congruent proportion.
Work:
72, 74, 76, 78, 80, 82, 92, 92
The two middle numbers are 78 and 80 since its even there is no true middle number
Therefore, add the two scores 158. Then divide by 2.
Answer: 79
Answer:
The total of people is the 100%.
68% owns a tv.
72% owns radios.
12% does not own anything.
Now, if we add those, we have:
12% + 68% + 72% = 152%.
This is larger than the 100%, then this means that there is a percentage of people that have both Tv and Radio, this percentage is:
152% - 100% = 52%
We have a surpass because we are adding those 52% two times (because they belong in two different groups)
So, the table is:
68% owns a tv.
72% owns a radio.
12% does not own anything.
52% owns both, radio and tv.
68% - 52% = 16% owns only tv.
72% - 52% = 20% owns only radio.
Then the Venn diagram consist in two circles, one with the 72%, other with the 68%, in such way that the circles have an intersection of the 52%.
Answer:
It will take nine years and four months for the refrigerator to pay for itself.
Step-by-step explanation:
The new refrigerator which costs $1200, saves the family 22% annually in energy cost.
Since the old refrigerator costs $580 to run, we want to determine how many years it will take for 22% of $580 per year to make $1200.
22% of $580
= 580 × 0.22
= 127.6
That is, it saved then $127.6 per year.
Now,
$1200/127.6
≈ 9.4
Which means, it will take 9 years and 4 months for the refrigerator to pay for itself.
