we know that 9*9 = 81, so let's start there.
0.9 * 0.9
one amount has 1 decimal, the second amount has another decimal, so in the product, we must have two decimals, let's do the multiplication without the dot.
09 * 09 = 81
but we must have two decimals, so that becomes 0.81.
0.09 * 0.9
here we do the same, the multiplication without the dot, and then we add as many decimals, in this case is 3 decimals, first term has 2 and the second term has 1 decimal, so the product must have 3 decimals.
009 * 09 = 81
getting those 3 decimals.......... 0.081.
0.009 * 0.9
here we do the same
0009 * 09 = 81
the product needs 4 decimals, so................ 0.0081.
0.009 * 0.09
we do the same here
0009 * 009 = 81
since the product needs 5 decimals................. 0.00081.
Answer:
I'd say A
Step-by-step explanation:
Reason: Because B and C are both having bands there and the cafeteria has the students popular opinion where there isn't band influence.
We can rewrite this problem as:
What is 60% of 35?
"Percent" or "%" means "out of 100" or "per 100", Therefore 60% can be written as
60
100
.
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number of members we are looking for "m".
Putting this altogether we can write this equation and solve for
m
while keeping the equation balanced:
m
=
60
100
×
35
m
=
2100
100
m
=
21
21
members must be present to have a vote.
The original inequality is -3x+4 > 19
Let's replace x with -4 and see what happens.
-3x + 4 > 19
-3(-4)+4 > 19
12+4 > 19
16 > 19
The last inequality is false, so the original inequality is false when x = -4.
This means x = -4 is not a solution to -3x + 4 > 19
---------------------
Let's plug in something larger. Let's say x = -3 which is one space to the right of -4 on the number line.
So we get...
-3x + 4 > 19
-3(-3) + 4 > 19
9 + 4 > 19
13 > 19
This doesn't work either. The value x = -3 is not a solution.
-------------------
Let's determine which x values will work by solving for x
-3x + 4 > 19
-3x + 4 -4 > 19-4 ... subtracting 4 from both sides
-3x > 15
-3x/(-3) < 15/(-3) ... divide both sides by -3; inequality sign flips
x < -5
The solution set consists of values smaller than -5
So values like {-6, -7, -8, -9, ...} and decimal values as well in that interval.
12% is the percent decrease
95,920 is 88% of 109,000.
x/100 = 95,920/109,000
95,920 x 100 = 9,592,000
9,592,000 / 109,000 = 88
100 - 88 = 12
Since it is 88% of it, it decreased by 12%
