HELP QUICK!!! What is the percent of change when a savings account goes from $128 to $112?
Answer:
The percent of change is –12.5%.
Answer:
-800%
Step-by-step explanation:
1. you have to do 128-112 and you get 16.
2. you then take 128 and divide by 16 and you should get 8.
3. you take 8 and multiply it by 100 and you should get 800.
4. and since you are going from 128 to 112 you are decreasing so the final number will be negative.
hope this helped!

SHOW THE STEPS
Answer:
3
Step-by-step explanation:
1. Using the order of operations, start with the multiplication.
2 x 4 = 8
2. Now do the addition problem first, because when up to using the pair of addition and subtraction do the problem that comes first.
1 + 8 = 9
3. Now finish it off with the subtraction part.
9 - 6 = 3
Order of operations:
1. Parenthesis
2. Multiplication/Division (what ever comes first)

Questions:
1.Which expression is a factor of n^2+3n-54?
2. The trinomial x^2-14x+49 can be expressed as?
1. (n+9) • (n-6) is the answer
The required, 1. factor of the expression n²+ 3n - 54 = (n + 6)(n - 9), 2. x² - 14x + 49 can be expressed as (x - 7)².
What are the factors?A number or algebraic expression that evenly divides another number or expression—i.e., leaves no remainder—is referred to as a factor.
3.
To factor the quadratic expression n² + 3n - 54, we need to find two numbers whose product is -54 and whose sum is 3. These numbers are 6 and -9.
Therefore, we can write:
n²+ 3n - 54 = (n + 6)(n - 9)
So the expression (n + 6)(n - 9) is a factor of n² + 3n - 54.
2.
The trinomial x² - 14x + 49 can be expressed as the square of a binomial. Specifically, it is the square of (x - 7):
(x - 7)² = (x - 7)(x - 7) = x² - 14x + 49
Therefore, x² - 14x + 49 can be expressed as (x - 7)².

The height, h, in feet of a kicked soccer ball can be modeled by the function h(t) = -16t2 + 24t + 1, where t is in seconds. On its way down, the ball bounces off the crossbar of the goal, which is 8 feet above the ground. To the nearest tenth, when did the ball hit the cross bar?
Answer:
Step-by-step explanation:
let the height of a kicked soccer ball be expressed by the function:
h(t) = -16t^2 + 24t + 1 where t is in seconds
The ball hit the cross bar when the height is zero
The equation becomes
0 = -16t^2 + 24t + 1
16t^2 - 24t - 1= 0
t = 24±√24²-4(16)(-1)/2(16)
t = 24±√576+64/32
t = 24±√640/32
t = 24+25.298/32
t = 49.298/32
t = 1.54 secs
Hence the ball hit the cross bar at t = 1.6secs (to the nearest tenth)

Alejandro said that the slope of the line in the Example is because for points
2
(2, 140) and (0,0), the rise is 140 and the run is 2. Is Alejandro correct? Explain.
Answer:
Step-by-step explanation:
slope = M = rise/ run
P1=(2,140)
P2=(0,0)
M= (Y2-Y1) / ( X2-X1)
M = 0-140 /0-2
M = -140 / -2
M = 140 / 2
Yes, Alejandro is right
The slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.
Given information-Points of the line are (2,140) and (0,0).
The rise of the line is 140.
The run of the line is 2.
Slope of the line-
Slope of a line describes the steepness and the direction of the line. The slope of of line passing through the point [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] can be given as,
[tex]m=\dfrac{(y_2-y_1)}{(x_2-x_1)} [/tex]
Thus the slope of the line with points (2,140) and (0,0) is,
[tex]m=\dfrac{(0-140)}{(0-2)} \\ m=\dfrac{140}{2} \\ [/tex]
As the slope of the line is the ratio of rise to the run. Therefore the line with points (2,140) and (0,0) has rice 140 and run 2. Hence the statement given by the Alejandro is correct.

what is the slope of the graph of 2x - 5y =20
Answer:
2/5
Step-by-step explanation:
convert to slope-intercept form y=mx+b:
2x - 5y = 20
-5y = 20 -2x
y = -4 (-2/-5)x
y = 2/5x - 4
the slope of the graph represented by 2x - 5y = 20 is 2/5.
To find the slope of the graph represented by the equation 2x - 5y = 20, we need to rearrange the equation into slope-intercept form (y = mx + b), where m is the slope.
Let's start by isolating the term with y:
2x - 5y = 20
-5y = -2x + 20
Next, divide the entire equation by -5 to solve for y:
y = (2/5)x - 4
Comparing the equation with the slope-intercept form, we can determine that the slope (m) is 2/5. Therefore, the slope of the graph represented by 2x - 5y = 20 is 2/5.

You run 1/3 of that distance on a hill.
You run down a slope for the last 1/2 of the hill.
To find:
The distance you run down the slope.
Solution:
We have,
Total distance [tex]=2\dfrac{1}{2}\text{ miles}[/tex]
You run 1/3 of that distance on a hill.
Distance on a hill [tex]=\dfrac{1}{3}\times 2\dfrac{1}{2}\text{ miles}[/tex]

Convert 3.16 repeating to a fraction. Explain your strategy or show steps you used to convert the number.
What is 3.16161616161616161616 as a fraction?
To write 3.16161616161616161616 as a fraction you have to write 3.16161616161616161616 as numerator and put 1 as the denominator. Now you multiply numerator and denominator by 10 as long as you get in numerator the whole number.
3.16161616161616161616 = 3.16161616161616161616/1 = 31.616161616162/10 = 316.16161616162/100 = 3161.6161616162/1000 = 31616.161616162/10000 = 316161.61616162/100000 = 3161616.1616162/1000000 = 31616161.616162/10000000 = 316161616.16162/100000000 = 3161616161.6162/1000000000 = 31616161616.162/10000000000 = 316161616161.62/100000000000 = 3161616161616.2/1000000000000 = 31616161616162/10000000000000
And finally we have:
3.16161616161616161616 as a fraction equals 31616161616162/10000000000000
Step-by-step explanation:
