Albert had a goal of saving $80. He saved 115% of his goal. How much money did Albert save
Answer:
$92
Step-by-step explanation:
A certain brand of laundry detergent is manufactured for $4.40 and then marked up 25% by the local store before selling. The store offers a 30% discount with the purchase of three or more bottles of the detergent. Showing all work, determine the total cost, before tax, of three bottles of detergent. (10 points)
Using proportions, it is found that the total cost of three bottles of detergent is of $11.55.
What is a proportion?A proportion is a fraction of a total amount.
A certain brand of laundry detergent is manufactured for $4.40 and then marked up 25% by the local store before selling, hence the price of each bottle is given by:
P = 4.40 x 1.25 = $5.50.
The store offers a 30% discount with the purchase of three or more bottles of the detergent, hence the total cost is given by:
T = (3 x 5.50) x 0.7 = $11.55.

How are samples classified?Samples may be classified as:
Convenient: Drawn from a conveniently available pool.Random: All the options into a hat and drawn some of them.Systematic: Every kth element is taken. Cluster: Divides population into groups, called clusters, and each element in the cluster is surveyed.Stratified: Also divides the population into groups. Then, a equal proportion of each group is surveyed.In this problem, he wants a systematic sampling, hence he should choose every kth word, which means that the answer is between options a and b.
He will choose 500 words out of 100,000, hence the value of k is given by:
k = 100000/500 = 200.
Which means that option B is correct.

The requried correct step when using the method of completing the square to solve the equation 2x² - 12x + 6 = 0 is A. (x - 3)² = 6.
What is simplification?Simplifying an expression involves eliminating unnecessary variables, components, or processes using algebraic and mathematical principles. The goal is to obtain an expression that is easier to use, manipulate, or solve.
Here,
To solve the quadratic equation 2x² - 12x + 6 = 0 using the method of completing the square, we can follow these steps:
Divide both sides by the coefficient of x^2 to make the coefficient of x² equal to 1:
x² - 6x + 3 = 0
Add and subtract the square of half the coefficient of x:
x² - 6x + 9 - 9 + 3 = 0
Factor the first three terms:
(x - 3)² - 6 = 0
Add 6 to both sides:
(x - 3)² = 6
Therefore, the correct step when using the method of completing the square to solve the equation 2x² - 12x + 6 = 0 is A. (x - 3)² = 6.

The graph below shows the cost, in
dollars, per notebook at the school store.
Which equation represents the total cost, T, per n notebooks?
Answer:
t = 2.4n
Step-by-step explanation:
y = mx + c
t = mn + c
c = y-intercept (where the graph line crosses the cost line)
c = 0
mx/mn= gradient ( rise/run, up/across)
mn= 12/5 ( you could have picked any point in the graph )
mn= 2.4
the m is unnecessary now so we discard it
t = 2.4n + 0

Find the x- and y-intercepts of the equation - 4x + 2y = 20
Answer:
y-intercept: 20
x-intercept: 5
Step-by-step explanation:
First, you want to rearrange the equation to make y on one side
2y=20-4x
Next, the y-intercept is 20.
Then to find the x-intercept, you have to make the equation equal to 0.
20-4x=0
Now, you solve for x.
20-4x=0
-4x=-20
-x=5
x=5
The x-intercept is 5.
The population of Sheffield is 690,000 to the nearest thousand and the population of Nottingham is 730,000 to the nearest 1000.
Calculate the upper and lower bounds for the difference in population between Sheffield and Nottingham.
Please answer with clear instructions so that i can apply this to other questions
Answers:
lower bound = 39001
upper bound = 40999
========================================================
Explanation:
You'll have to think backwards to find what values round to 690,000 when rounding to the nearest thousand.
It turns out that if x is on the interval [tex]689,500 \le x \le 690,499[/tex], then x will round to 690,000 when rounding to the nearest thousand. The x refers to the population of Sheffield, so it's some integer in that range.
Through similar logic, if y is on the interval [tex]729,500\le y \le 730,499[/tex] then it will round to 730,000 when rounding to the nearest thousand. This represents the population of Nottingham.
-------------------
Now let's say we go for the smallest possible value of x (689500) and the largest possible value of y (730499). This guarantees the two populations are the most spread out or distant from one another. Subtract those two values:
730,499 - 689,500 = 40,999
This is the largest difference possible of the two populations. It represents the upper bound, i.e. it's the ceiling.
---------------------
On the other hand, let's now say x is as big as possible (690499) and y will be as small as possible (729500). Subtract those values:
729,500 - 690,499 = 39,001
This is the lower bound. It's the smallest the difference can be. It's considered the floor.
----------------------
Let d be the difference in the populations. In other words, d = y-x
We found that the lower bound was 39,001 and the upper bound was 40,999
Meaning that
[tex]39,001 \le y-x \le 40,999[/tex]
or
[tex]39,001 \le d \le 40,999[/tex]
find the solution of y=x+3 and y=2x+6
Answer:
x = 3 and y = 0
Step-by-step explanation:
To find the solution where you have two equations is called a System of Equations.
What you do is you notice there are two equations and the let both equations equal each other. We can do this because both equations start with a y. These "y" work like puzzles and you can connect the "x+3" and "2x + 6" together. Then solve for it. Here's what i mean,
y = x+3
y = 2x+6
Now connecting them,
x+3 = 2x+6
Subtract x from both sides
3 = x + 6
Subtract 6 from both sides,
x = -3
Now solve for y,
y = -3 + 3 = 0
So our solution is x = 3 and y = 0.
Answer:
(x, y) = (-3, 0)
Step-by-step explanation:
Substitution or elimination work well for solving this system of equations.
__
EliminationSubtract the first equation from the second.
(y) -(y) = (2x +6) -(x +3)
0 = x +3
-3 = x . . . . . . . subtract 3
y = (-3) +3 = 0 . . . . use the first equation to find y
(x, y) = (-3, 0)
__
SubstitutionUse the second equation to substitute for y in the first.
2x +6 = x +3
x = -3 . . . . . . . . . subtract x+6 from both sides
y = (-3) +3 = 0 . . . . find y using the first equation
(x, y) = (-3, 0)
