Answer:
50% ( rounded to the nearest tenth of a percent)
Step-by-step explanation:
In this question, we are asked to find the percentage decrease in the price of the bottle of water.
To do this, what we do is that we subtract the new price from the old price, then we divide the result by the old price and multiply the result by 100.
Mathematically,
Percentage decrease in price = (old price- new price)/old price * 100%
Percentage decrease in price= (2.65-1.4)/2.65 * 100%
1.25/2.65 * 100% = 47.2%
We were asked to round to the nearest tenth of a percent. This brings our answer to 50%
Answer:
19/24 = 0.791666667
Step-by-step explanation:
7/8 - 1/12
Least common multiple of 8 and 12 is 24. Convert 7/8 and 1/12 to fractions with denominator 24.
21/24 - 2/24
Since 21/24 and 2/24 have the same denominator, subtract them by subtracting their numerators.
21 - 2 / 24
Subtract 2 from 21 to get 19.
19/24
Answer:
1628.6cubic cm
Step-by-step explanation:
the volume of a cylinder formula:πr^2h
h(height)=3.6
π=3.14
r(radius)=12
so
3.14*12^2*3.6=
1628.6 cubic cm
hope this helps
Answer:
3 seconds
Step-by-step explanation:
It's quite simple. First, add 5cm to the progress of the insect, counting it as 1 second. Then subtract 2cm because it falls over the next second, thus taking another second. Then finally, plus 5cm, making it 3 seconds. It's not 4 seconds because at 3 seconds it had already reached the top.
