Hi there!
To find the percent discount, we need to divide the new price by the original price without the discount:
18 / 25 = 0.72
Now, we convert this into a percentage, so we can find the <em>percent </em>discount:
0.72 = 72%
Now, we subtract from 100%:
100% - 72% = 28%
So, the answer is 28%.
Hope this helps!
- <em>combined mass in scientific notation can be written as</em> 97.2× kg
- Scientific notation can be regarded as a way of writing very large as well as very small numbers.
Mars of mass= (6.42x kg )
Mercury= (3.3x kilograms)
Then we add together
(6.42x )+ (3.3x) kilograms.
= 9.45 × kilograms
Therefore, combined mass in scientific notation can be written as 97.2× kg

Let h be high temperature for today.
We are told that today high temperature will be at least 75 degrees. This means the high temperature will be greater than or equal to 75 degrees.
Let us represent this information by our inequality.
Therefore, our desired inequality will be .
The number of students who worked < 15 hours is decreasing as time goes on
THe correlation coefficient is negative.

Answer: 226 grams</h3>
==========================================
Explanation:
1/2 = 0.5
Every 60 days, the amount cuts in half.
We start with 904 grams and after 60 days, we have 904*0.5 = 452 grams left over.
After another 60 days, we have 452*0.5 = 226 grams left over.
-------------
Alternative Method:
We can apply the half-life formula.
y = a*(0.5)^(x/H)
where,
- y = final amount after x days
- a = initial amount
- x = number of days that elapse
- H = number of days in a half-life
In this case,
- a = 904 is the starting amount
- H = 60 is the number of days until another half-life occurs
When x = 120 days go by, we have....
y = a*(0.5)^(x/H)
y = 904*(0.5)^(x/60)
y = 904*(0.5)^(120/60)
y = 904*(0.5)^(2)
y = 904*(0.25)
y = 226 grams of antimony left over.
This method is preferred over the first method if you have x be some non-multiple of 60, or if x is fairly large.
