<h3>
Answer: Choice B) 122%</h3>
==========================================
Work Shown:
A = 1250 is the initial amount
B = 2780 is the new amount
C = percent change = unknown for now
The formula to use is
C = [ (B-A)/A ] * 100
to calculate the percent change.
Basically we calculate the change (B-A) first and then divide that over the original amount A to compute the decimal form of the answer, which is then converted over to percentage form. The "100" tacked on at the end is what converts from decimal to percent form.
---------
C = [ (B-A)/A ] * 100
C = [ (2780 - 1250)/1250 ] * 100
C = (1530/1250)*100
C = 1.224 * 100
C = 122.4%
C = 122%
---------
The positive C value indicates we have a percent increase. If C were negative, then we'd have a percent decrease.
Answer:
b) The distance between −12 and −1 is ∣∣−12−(−1)∣∣
Step-by-step explanation:
The point A = -1
The point B = -12
To find The distance from A to B on the number line.
Now, distance of a point B from the point A is given as I B - A I
Definition of Modulus Function
I x I = x, if x > 0
= -x if x< 0
Similarly, here the distance is given as
I B - AI = I (-12) - (-1) I = I -12 + 1 I
= I -11 I = -(-11) = 11 ( as x < 0)
or the distance of point B from point A = + 11 units.
Hence, I B - AI = ∣∣−12−(−1)∣∣
Answer:
answer is $149.70
Step-by-step explanation:
total add 15
divide by 60
times by 100
85 multiplied by 1.20 is 102 minus 85 is equal to 17 pizzas
Hey there, Faithfuljoshua!
It's already given that the perimeter is 12 meters.
The length of the rectangle is 3 times more than it's width.
To do this, we can use an equation. Let's use the variable x
So, 3x + x = 12
3x being the length
x being the width
Now we solve for x
3x + x = 12
4x = 12 (Now we divide both sides by 4)
x = 3
Now, we have to replace the x values for 3
So, the length is 3x changes to 3(3) = 9 meters
And the width is x being 3 meters.
