Use at least 4 of the numbers 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9, and any operations or brackets to make each whole number from 1 to 5. (5 ways to make each number from 1 to 5.)
A tank has 62.3 litres of water. A tap drains out the tank with 3.7 litres of water in 1 minute and two times this amount of water in the next minute. How much water is in the tank now? How many minutes does it take to drain the water?
1. $5.31
18.1 * 2.95 = 5.31
2. 3.5 Frames
2.8/0.8=3.5
3. 3.75 feet
5 X 1.25 = 6.25
10 - 6.25 = 3.75
4. 0.1 * 10 = 1
0.2 * 5 = 1
0.5 * 10 = 5
5. 51.2 L
7 Minutes
62.3 - 3.7 = 58.6
58.6 - 7.4 = 51.2
51.2/7.4 = 7 Minutes (Simplified)

Answer:
_
10.6
hope dis helps ^-^
The requried value of 2/3 fraction of 16 is 10 and 2/3, or approximately 10.67.
To find 2/3 of 16, you can multiply 16 by the fraction 2/3:
(2/3) * 16 = (2 * 16) / 3
Now, calculate the numerator:
2 * 16 = 32
So, the result is:
(2/3) * 16 = 32 / 3
Next, simplify the fraction:
(2/3) * 16 = 10 and 2/3 or 10.67 (rounded to two decimal places)
Therefore, 2/3 of 16 is 10 and 2/3, or approximately 10.67.

dexter needs to find each angle in this figure that is adjacent to (the second question)
The Adjacent angle to <LON are <NOP, <NOK and <LOK.
What are adjacent angle?When two angles share a shared vertex and side, they are said to be neighbouring angles. The vertex of an angle is the terminal of the rays that create the sides of an angle. When two adjacent angles have a common vertex and side, they might be complimentary or supplementary angles.
Now, the adjacent angle to <LON are <NOP, <NOK and <LOK.
Dexter claim is wrong because <MON is not adjacent to <LON, <MON is just a part of <LON.
and, the part of an angle cannot be considered as Adjacent angle.

26 – x = 14. what is x
Answer:
x=12
Step-by-step explanation:
start with this equation:
26-x=14
it's best to make the x variable positive at all times.
to do that, you need to make everything else positive.
-26+x=-14
then add 26 to both sides.
x=-14+26
which basically says 26-14...
x=12
