Find percentage of change. Round to the nearest whole number if necessary. State whether the percent of change is an increase or decrease.
Answers

Going from 40 to 25 is a decrease of 15. Comparing that 15 to the starting amount of 40, we have a decrease of [tex]\dfrac{15}{40}[/tex] or 0.375 or 37.5%. Since you need to round to the nearest whole number, that'd be a decrease of about 38%.
14.
Going from 120 to 140 is an increase of 20. Comparing that 20 to the starting amount of 120, we have an increase of [tex]\dfrac{20}{120}[/tex] or about 0.1667 or about 16.67%. Since you need to round to the nearest whole number, that'd be an increase of about 17%.
You always divide the amount of change by the starting value, not the ending value.

Samantha is buying a chromebook that costs $179.00. The chromebook is on sale for 35% off the original price. How much will the chromebook cost after the discount?
Answers
Answer:
$116.35
Step-by-step explanation:
179 x 35/100
= 62.65
This is how much will be taken off of the original price. So we have to subtract that from 179.
179 - 62.65 = 116.35
The new price is $116.35
Answer:
$116.25 after the discount
Step-by-step explanation:
$179 - 35% = x
$179 - $62.25 = $116.75

A full grain silo empties at a constant rate. write an expression to determine the amount of grain left after s seconds
Rate ; 3.5ft 3/s
Capacity ; 3000ft3
Answers
m is the slope.
b is the y-intercept.
the slope is the same as he constant rate.
let y = the number of feet of grain left in the silo.
let x = the number of seconds.
you get y = -3.5 * x + b.
when x = s seconds, the equation becomes y = -3.5 * s + b.
b is the y-intercept which is the value of y when x = 0.
when x = 0, no seconds have elapsed and the silo is therefore at whatever height it was before you started to empty it.
that would be the value of b.
if we assume that the height of the grain in the silo was 150 feet, then the formula would become: y = -3.5 * x + 150
after s seconds, the formula would become y = -3.5 * s + 150.
if s was equal to 20, then the formula would become y = -3.5 * 20 + 150 which would then become y = -70 + 150 which would then become y = 80.
after 20 seconds, there would be 80 feet of grain left in the silo.

Answer: -5/4
Step-by-step explanation:
It is this because it is a downward slope, and so it has to be negative. The points are 10 at the top and eight at the bottom. But Because the slope goes down to the right, it means that it is going to be negative. So, -10/8 can be simplified down to -5/4 when divided by 2. Hope this helps.

They are not similar.
Step-by-step explanation:
In triangle ABC, the angle we are given is in between the two defined sides(AB and BC with angle B). If these triangles were similar, we would see this with the SAS postulate.
In triangle KLJ, the angle is not in between the two sides, so they are not similar according to any of these two postulates.

The initial value is also known as the y-intercept, and as you can see on the graph, the y-intercept is 1.
You could also use the formula
y=mx+b, b is the y-intercept, m is slope, y and x are coordinates.
We see one of the coordinates in (-2,0) so x=-2 and y=0
The slope, or rate of change, is 1/2, so m=1/2

Pet supplies makes a profit of $5.50 per bag on it’s line of natural dog food. If the store wants to make a profit of NO LESS THAN $5225, how many bags of dog food does it need to sell???
10 pts for a clear explanation
Answers
because 5225 divided by 5.50 is 950
I think this is correct
Answer:
the pet store needs to sell 950 or more bags of dog food.
Step-by-step explanation:
Let’s define our variable: x= number of bags of dog food.
Since we need to make more than or 5225 dollars, we need to make an inequality to show this.
[tex]5.50x\geq 5225[/tex]
Let’s solve the inequality.
[tex]5.50x/5.50 \geq 5225/5.50[/tex]
[tex]x\geq 950[/tex]
So, the pet store needs to sell 950 or more bags of dog food.

(PLEASE HELP) What is the slope of the line that contains the points (2, −7) and (−1, 5)?
A: −4
B: negative one fourth
C: one fourth
D: 4
Answers
You do 5 - -7=12 and then do -1 -2 which is -3 and then you do 12/-3=-4
Equation m = -4 gives the slope of the line.
What exactly is a line equation?A line's equation is written as y = mx + b, where m denotes the slope and b the y-intercept.
And m (x - x1) = y - y1
y = the second point's y-coordinate
y1 = the y-coordinate for point one, m = the slope, and x = the x-coordinate for point two.
x1 = the point one's x coordinate
The m = y/x slope
Given the data,
Right now, A is valued at
Let P be the initial point ( 2 , -7 )
Let Q be the second point ( -1 , 5 )
The slope of the line is now given by m = (y2 - y1) / (x2 - x1).
Slope m is equal to (-7 - 5) / (2 - (-1)
The equation is simplified to give Slope m = -12 / 3.
Slope m = -4
Hence, m has a value of -4.
As a result, the line's slope is m = -4.
