Answer:
50% value change.
Step-by-step explanation:
A 100% increase from 10 would be 20. It's the equivalent of doing 10 times 2. We need 15 though which is half the distance in value to 10 than 20 is. Half of 100% is 50%.
Therefore, $15 is a 50% percent change from $10.
PEMDAS Solve the parentheses first so 9+4=13. Then do the division so 6/6=1. Now the equation is 37- 13+ 1. Then work left to right. 37-13= 24 then 24+1=25.
Y² - 12y + 32
The middle term must be written in such a way that the sum of two numbers is -12y and the product is 32y²
The two such numbers are -4y and -8y
So, we can write:
y² - 4y - 8y + 32
= y(y - 4) - 8(y - 4)
= (y - 4)(y - 8)
So, option B gives the correct answer
Answer:
0.85 of the original piece of lumber remains.
Step-by-step explanation:
Well, this lumber piece of lumber started as 2.5 meters long. Then, a 1.65 meter piece was cut off of it. All we need to do is subtract.
2.5 - 1.65 =
2.50 - 1.65 = 0.85.
Therefore, 0.85 of the original piece of lumber remains.
