he makes 90 dollars and wasted 34 so he has 56 left
When you want to round a number to the nearest hundredths
1.1<u>0</u><u />8
The 0 is in the hundredths place. So you look at the number to the right of the 0, is 8.
1.10<u>8</u>
If the number to the right is 5 or higher you round up, if it's under 5 you round down.
So 1.108 rounded to nearest hundredth is <u> </u>
<u>1.11</u>
Hope this helps. :)
Assume that the rule connecting height of the candle to time is a linear one. If you do, then we have to find the equation of this line, and then use this equation to predict the height of the candle after 11 hours.
Two points on this line are (6,17.4) and (23, 7.2). The slope is thus
7.2-17.4 -6
m = --------------- = ----------- or -3/5.
23-6 10
Find the equation of the line. I'm going to use the slope-intercept formula:
y = mx + b => 7.2 = (-3/5)(23) + b. Solving for b, b = 21.
Now we know that y = (-3/5)x + 21
Let x=11 to predict the height of the candle at that time.
y = (-3/5)(11) + 21 = 14.4 inches (answer)
Answer:
12
Step-by-step explanation:
find 20% of 15 and then take that away from the 15
Simply add 25% to 100% and you will get 125%
125% should be decreased to restore the original price
Example: $80 x .25 = $20
$20 + $80 = $100
$100 ÷ 125% = 80
