How do you get the answer 3a -5 from: -3a - (5-6a)?
Answers
The 'minus sign' ( - ) before the parentheses says that in order to
get rid of them, you have to change the sign of each term inside.
-3a - (5 - 6a) is the same as
-3a -5 + 6a
Add up the (-3a) and the (+6a) and you have +3a .
So the whole thing becomes 3a - 5 .

What does the number 0.7 represent?
The ball bounces to 30% of its previous height with each bounce.
The height at which the ball bounces at the nth bounce is 0.3 feet.
The ball bounces to 70% of its previous height with each bounce.
The height from which the ball was dropped at the nth bounce is 0.7 feet.

Answer:
The ball bounces to 70% of its previous height with each bounce.
Step-by-step explanation:
In physics terminology, the number 0.7 is the coefficient of restitution. It is the ratio of the height of bounce (n+1) to the height of bounce (n).
The meaning of the number is that the ball bounces to 70% of the height of the previous bounce.
Answer:
The ball bounces to 70% of its previous height with each bounce.
Step-by-step explanation:
A ball is dropped from a certain height. The function below represents the height f(n), in feet, to which the ball bounces at the nth bounce:
f(n) = 9(0.7)n
The number 0.7 represents that the ball bounces to 70% of its previous height with each bounce.

If the next number is 125% of the previous number, that means that the previous number is increasing by 25% each time.
The multiplier for increasing by 25% is:
(100 + 25) ÷ 100 = 1.25
So on day one, there are 64 responses. That means on day two, there will be:
---> 64 x 1.25 = 80 responses
On day 3, there will be:
---> 80 x 1.25 = 100 responses
Finally, on day 4, there will be:
---> 100 x 1.25 = 125 responses
A quicker way of getting this would be to do:
64 x 1.25³ since you are multiplying by 1.25 3 times

Let's find the length of JL as a first step. Knowing the result, we can easily find x.
|JL| 1
sin 30 degrees = ----------------- = --------
8√2 2
Then 2 |JL| = 8√2, or |JL| = 4√2
Next, find x: sin 45 degrees = x / |JL| = x / [4√2], and since sin 45 degrees is 1 / [√2],
1
x / [4√2] = -------- which results in x = 4

As per the given statement: when the lights go out at the store at night there's a 15% off sign hanging out by the make up counter.
To find the number as a decimal and a fraction in simplest form.
Given the Number = 15%.
If we convert any number from percent to decimal divide by 100 and remove the % sign.
Then the given number in decimal is, 0.15
Now, to convert this percent into fraction;
Divide both numerator and denominator by 5 to get;
Therefore, the given number in fraction is;
