Answer:
12.90
Step-by-step explanation:
The hundredth is the second decimal place.
Basically we want to drop the numbers after the 9.
12.89 <u>5</u>03
Use the underlined decimal place, right after what you are rounding to, to determine if you round up or down.
For numbers 0-4, round down (keep the number). For numbers 5-9, round up (increase by 1).
We need to round up because 5 is in the range 5-9.
"Add" 1 to the hundredth decimal place and treat it like addition:
. 12.89
<u>+ 0.01</u>
. 12.90
The have been saving for 10 weeks.
Given:
Duane = $5 every other week. meaning every 2 weeks
Mick = $2 every week
Amount Saved = $45
First, divide Duane's $5 by 2 to get his weekly contribution.
$5/2 = $2.50
let x be the number of weeks.
Duane + Mick = $45
2.50x + 2x = 45
4.50x = 45
4.50x/4.50 = 45/4.50
x = 10 weeks
to check:
2.50x + 2x = 45
2.50(10) + 2(10) = 45
25 + 20 = 45
45 = 45
Answer:
4
Step-by-step explanation:
The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.
If you add 2 and 4, you will get 6. This is the right answer because the only answer that is incorrect is the 4th, it has to equal a minimum of 7, not 6.
2/5 plus 27/9 minus 0 equals 0
