Answer:
k^2-8k+12=0D
Step-by-step explanation:
Explanation:
1) Given equation:
k+12/k=8
2) Multiplication property of equality:
k(k+12/k)=8k
3) Distributive property:
k^2+12k/k=8k
4) Simplification:
k^2+12=8k
5) Subtraction property of equality:
k^2-8k+12=0
The original price is 100% of the price. If the price is marked 60% off, then you pay 40% of the original price.
An item costs x dollars.
With the 60% off discount, it now costs 40% of x, or 0.4x.
Now you apply a 30% discount.
For the second discount, consider the price 0.4x to be the new original price. If the price is now discounted 30%, you will pay 70% of the new original price.
Start with 0.4x.
Now calculate 70% of 0.4x.
70% of 0.4x = 0.70 * 0.4x = 0.28x
After applying the 60% discount and the 30% discount, the item that originally cost x now costs 0.28x. 0.28x is the same as 28% of x. The amount you pay is 28% of the original price.
Answer: 28%
If the analyst wants an average of all fastballs, it is not useful to measure other pitches, nor is it useful to limit it to a subset of the pitchers.
So, the sample should draw from all fastballs.
Answer:
DE = 6.3
Step-by-step explanation:
The length of the midsegment of a triangle is half the length of the side it is parallel to.
Side DE is parallel to side CA and side CA is 12.6.
12.6/2 = 6.3
DE = 6.3
Miriam will have no apples left after the 7th day of baking.
Here is the number of apples she will have after each day starting with after the 1st day of baking.
126, 108(1st day), 90(2nd day), 72(3rd day), 54(4th day), 36(5th day), 18(6th day), 0(7th day).
Each day the number of apples decreases by 18.
