Find the percent of change:
From 64 feet to 48 feet
Answers
Answer:16
Step-by-step explanation:
Using this tool you can find the percent Decrease for any value. So, we think you reached us looking for answers to questions like:
1) What is the percentage Decrease from 64 to 48? 2) What is the absolute Decrease from 64 to 48. Or may be: What is the percent change from 64 to 48?
See the solution to these problems just after below.
How to calculate percent change - Step by Step
Percent increase or decrease measures percent changes between two values. Use this calculator when comparing an old value to a new value.
The Percent Calculator (Change) uses this formula:
% change = New Value - Old Value|Old Value|× 100%
Where |Old Value| represents the absolute value of the reference (this is made in order to work well with both positive and negative values of Old Value and New Value. Note that percent change and relative change mean the same thing. It can be a percent increase or a percent decrease depending on the new and the old values. If the new value is greater than the old value, the result will be positive and we will have a increase. On the other hand, if the new value is smaller than old value, the result will be negative and we will have a we have a decrease. The old value, as a reference, may be: a theoretical, the actual, the correct, an accepted, an optimal, the starting, and so on. See more about percent percent change here.
Here are the solutions to the questions stated above:
1) What is the percentage decrease from 64 to 48?
Use the above formula to find the percent change. So, replacing the given values, we have
Percent change = 48 - 6464 x 100 = -25 % (decrease)
Where: 64 is the old value and 48 is the new value. In this case we have a % of decrease because the new value is smaller than the old value.
2) What is the absolute Decrease from 64 to 48?
This problem is not about percent or relative change, but about absolute change. Its solution is very simple:
Absolute change, or
change = new value - old value
= 48 - 64 = -16 (decrease)
Answer: -25%
Step-by-step explanation:A change from 64 to 48 represents a negative change (decrease) of -25%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = New - Old
|Old|
x 100%
Percent change = 48 - 64
|64|
x 100 = -16
64
x 100 = -25 % (decrease)
Where: 64 is the old value and 48 is the new value. In this case we have a negative change (decrease) of -25 percent because the new value is smaller than the old value.

Answer:
x = 20
p =54
y= 54
Step-by-step explanation:
2x-4 = 96-3x
5x = 100
x = 20
2x-4 = 40-4 = 36
(180 - (36 x 2))/2

Answer:
The first: y = -25x + 180Step-by-step explanation:
In every equation b = 170, so
The equation is y =mx + 170
On the line on the graph, for x=2 we have y = 120,so:
120 = m×2 + 170
-50 = 2m
m = 25
Therefore the equation is:
y = -25x + 180

Rachel signed up for a frequent-flier program. She receives 4,300 frequent-flier miles for her first round trip and 1,900 frequent-flier miles for each additional round-trip. How many frequent-flier miles will she have after 5 round-trips?
Answers
Answer: 13800 frequent-flier miles
Step-by-step explanation:
From the question, we are informed that Rachael receives 4,300 frequent-flier miles for her first round trip and 1,900 frequent-flier miles for each additional round-trip.
The number of frequent-flier miles she will she have after 5 round-trips will be:
= 4300 + 1900(5)
= 4300 + 9500
= 13800 frequent-flier miles

Answers
Note: The expression you have written sounds a little unclear, but I am assuming your expression is (27)-2-2/3.
So, I am solving the question based on assuming the expression as (27)-2-2/3, which would still clear your concept.
Answer:
The expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
simplifying the expression in the simplest form
[tex]\left(27\right)-2-\frac{2}{3}[/tex]
[tex]=25-\frac{2}{3}[/tex]
[tex]=\frac{25\cdot \:3-2}{3}[/tex]
[tex]=\frac{73}{3}[/tex]
Thus, the expression in the simplest form is:
[tex]\left(27\right)-2-\frac{2}{3}=\frac{73}{3}[/tex]
