Answer:
33.99
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 39.99 × 15/100
Discount = 39.99 x 0.15
You save = $6.00
Final Price = Original Price - Discount
Final Price = 39.99 - 5.9985
Final Price = $33.99
Answer:
Approximate ≈ $33.99
Step-by-step explanation:
Original: 39.99
New: x
Percent Decrease: 15%
15% of 39.99 = 0.15(39.99) = 5.9985
39.99 - 5.9985 = 33.9915 = 33.99

How do you write 7
11
/
18
as a whole number
Answer: 8
Step-by-step explanation
Write as a decimal
7 11/18 is equal to 7.6111
Round the decimal to the nearest whole number:
If you have a decimal that is greater than or equal to 5 in the tenths place then you round up. Ex: 5.8 would be rounded to 6, 1.5 would be rounded to 2.
If you have a decimal that is less than or equal to 4 in the tenths place then you round down. Ex: 5.1 would be rounded 5, 1.2 would be rounded to 1.
Since 6 is in the tenths place we round up. 7 11/18 can be written as 8 (as whole number)
3/4 of what number equals 36 ?????????
Answer:
48
Step-by-step explanation:
This question can be written as 3/4 times a number equals 36.
To multiply by 3/4 we would times 36 and 3 and then divide by 4.
We will do the opposite to find our unknown number
36 ÷ 3 = 12
12 × 4 = 48
The number of the solution will be 48.
What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The expression is,
3/4 of a number is equal 36.
Now,
Let a number = x
So, we can formulate;
⇒ 3/4 of x = 36
Solve for x as;
⇒ 3/4 × x = 36
Multiply by 4 as;
⇒ 3/4 × 4x = 36 × 4
⇒ 3x = 36 × 4
Divide by 3, we get;
⇒ x = 36 × 4/3
⇒ x = 12 × 4
⇒ x = 48
Thus, The number of the solution will be 48.

ibrahim buys bags of coloured marbles blue marbles are sold in bags of 10 green marbles are sold in bags of 6 and white marbles are sold in bags of 12 ibrahim wants to buy an equal number of blue ,green and white marbles ,what is the smallest number of bags of each colour hecould buy
The smallest number of bags of each colour that he could buy is 60.
How to calculate the value?From the information, Ibrahim buys bags of coloured marbles. The blue marbles are sold in bags of 10 green marbles are sold in bags of 6 and white marbles are sold in bags of 12.
Since ibrahim wants to buy an equal number of blue ,green and white marbles, the smallest number of bags will be the lowest common multiple of the numbers. This will be:
6 = 6, 12, 18, 24, 30, 36, 42, 48, 54 and 60
10 = 10, 20, 30, 40, 50, 60
12 = 12, 24, 36, 48 and 60
The smallest common multiple is 60.

If she competed 10 miles in 45 minutes. Calculate her speed per second.
Answer:
Step-by-step explanation:
0.0037037045455 of a mile or 19.55556 feet per second
Answer: 1/270 miles per second
Step-by-step explanation:
Speed is equal to distance over time (s=d/t).
We can plug in 10 miles as distance, and 45 minutes as the time; however, you multiply the time by 60 since a minute has 60 seconds. The equation then becomes:
s=10/45*60
s=10/2700
s=1/270
Her speed is 1/270 mps.

Valerie manages a team of 30 employees at a large company. She wants to survey members of her team on her
performance as their manager. She holds an individual meeting with each of her team's members and asks them
the same set of questions. Valerie finds that 83% of her employees rate her performance as "outstanding."
Which of these is the best explanation for why this result is probably biased?
Choose 1 answer:

Only members of Valerie's team are being polled, so this is likely an overestimate of Valerie's
performance.
Only members of Valerie's team are being polled, so this is likely an underestimate of Valerie's
performance
Using the concept of bias, it is found that the correct option is:
(A) Employees may not want to give critical feedback in person to their manager, so this is likely an overestimate of Valerie's performance.
Samples have to be well chosen, otherwise, there can be a source of bias. For example, if you want to make a survey about who is better, Pele or Maradona, if you choose only Brazilians, or only Argentinians, the results will be biased, thus a sample with an equal number of Brazilians and Argentinians should be used.
In this problem, Valerie's is their manager, and the employees may be reluctant to give her critical feedback, which means that the proportion of 83% is an overestimate, and the correct option is:
(A) Employees may not want to give critical feedback in person to their manager, so this is likely an overestimate of Valerie's performance.

Graph the equation.
y-1=-2(x-5)
Step-by-step explanation:
y - 1 = -2(x - 5)
Distribute -2 into the parenthesis:
y - 1 = -2x + 10
Add 1 to both sides:
y - 1 + 1 = -2x + 10 + 1
y = -2x + 11 (This is the slope-intercept form where the slope, m = -2, and the y-intercept, b = 11).
Using the slope (m = -2) and the coordinates of the y-intercept, (0, 11):
Plot the y-intercept on the graph. Then, use the slope's "rise over run" technique (2 units down, and 1 unit to the right) to plot other points. Connect the points by drawing a line over them.
Attached is a screenshot of the graph that I created using the techniques provided in this post.

Amy bakes 12 cookies for a party at her friends house she puts 4 cookies in a bag.
Answer:
3?
Step-by-step explanation:
does anyone know how to do this
Step-by-step explanation:
So you're going to try to always make the equation be in a y= mx +b point slope form. It just makes creating a graph easier.
First, we're going to put x to the opposite side so it's in the y= mx + b form. Remember that every time you cross the equal sign you do the opposite -[tex]x^{2}[/tex] turns into + [tex]x^{2}[/tex].
y- [tex]x^{2}[/tex] = -1 becomes y = [tex]x^{2}[/tex] -1.
Now all you have to do is plug in values. I recommend you start off small, so they can fit in your graph.
An example would be x = 2 now you plug in to find y which is [tex]2^{2}[/tex] = 4 -1 = 3. So you graph the point (2, 3).
To find the x- intercept and y- intercept you need to plug in 0. For the y-intercept, plug in 0 for x, since you're trying to find the y.
y = [tex]0^{2}[/tex] - 1. The y-intercept is -1 or the point (0, -1)
For the x-intercept, plug in 0 for y, since you're trying to find the x.
0 = [tex]x^{2}[/tex] -1 . Because you're trying to find x, you need to isolate x. Move -1 to the other side. Again, remember since you're moving across the = sign it changes to be positive. 1 = [tex]x^{2}[/tex]. To get rid of squared, you're going to have to square root it. [tex]\sqrt{x^2}[/tex] = x and [tex]\sqrt{1}[/tex] = 1. So the x- intercept is 1 or the point (1, 0).
To make the graph, know that the y axis is vertical (up and down) and the x axis is horizontal (left right). So, the point (0,0) would be on the bottom left corner.
