Answer:
1/52 of a hour lol
Step-by-step explanation:
There is a very simple way of dealing with percentages.
"increase" means add
"decrease/discount/reduce" means subtract
Now, we know that the original price is 100%.
100% = 1 (like 50% = 0.5)
So if an object's price is x and it is 20% off, we get:
100%x - 20%x
Taking x common,
x(100% - 20%)
= 0.8x
Therefore, if we fist add/subtract the percentages we can multiply directly with the original to get the answer. This is as follows:
5] Increase 101 by 16%
1 + 0.16 = 1.16
So the answer is:
101 * 1.16
= 117.16
6] Decrease 36 by 21%
1 - 0.21 = 0.79
The answer is:
36 * 0.79
= 28.44
7] Let original price be x, we know it is 35% off
1 - 0.35
= 0.65
0.65x = 13
x = 20
Answer:
Step-by-step explanation:
Pay attention to the procedure:
(5(10)^2)^3/(10(5))^4. What we need is plug in the corresponding x and y values Then you have to do x squared before you multiply it by 5 like this: (5(100))^3/(10(5))^4 Now solve for what is in the top parenthesis. (500)^3/(10(5))^4 500^3=125000000 Now work on the denominator. Do what is inside the parenthesis first 10*5=50 Now (50)^4=6250000 Now divide the numerator and the denominator. 125000000/6250000 Which equals 20, Please check if I'm wrong but I think this is what you need
The guarantee which should be given by the manufacturer in years is; 0.405years
<h3>Percentages and Averages</h3>
Since the average life of a scooter is 12 years with a standard deviation of 1.5 years.
Hence, the maximum life of any electric scooter is 13.5 years.
On this note, to offer a guarantee with the intention to replace only 3% of the scooters;
We must evaluate 3% of 13.5 years as follows;
- Guarantee offer = 3% of 13.5 years
- Guarantee offer = (3/100) × 13.5
Guarantee offer = 0.405 years
