Nancy purchased some bed
sheets that cost $36. They were
on sale 25% off. What is the
new price of the bed sheets?
Answer:
To find the new price of the bed sheets, we can calculate the amount of discount first and then subtract it from the original price.
The bed sheets were on sale 25% off, so the amount of discount is:
$36 x 25/100 = $9
To find the new price of the bed sheets, we can now subtract the discount from the original price:
$36 - $9 = $27
So the new price of the bed sheets is $27.
Answer:
$36 * 0.75 = $27. That is the answer.
If 1.00 is 100 percent, subtract 0.25 or 25 percent from that to get 0.75 or 75 percent as the value which is left then multiply the original price, $36 to get the equation and answer above.
A $ suit is marked down by %. Find the sale price.
Question content area bottom
Part 1
The sale price is $
168. (Round to the nearest dollar as needed.)
The sale price of the suit is $168.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
Given:
The cost of the suit is $240 and the discount is 30%.
The sale price of the suit is:
240 - 30% of 240
= 240 - 30 × 240/100
= 240 - 72
= 168.
Therefore, $168 is the price of the suit.

A store's profit P varies directly with the number of items n that they purchase from a warehouse. Greg's gadgets buys 75 Wacky Widgets from Gadget Supply Warehouse. The store's profit for this purchase is -190. 50. How do I write a direct variation equation on that
The required equation will be k=-2.54n
The profit P of a retailer is said to be directly correlated with the quantity n of goods it purchases from a warehouse.
Since y is directly proportional to x and k is a constant of variation, we know that two proportional numbers have the form y=kx.
The result of inserting our provided variables is:
P=kn
We are also informed that Gadget Supply Warehouse sells 75 Wacky Widgets to Greg's Gadgets. The sale resulted in a loss of 190.50 for the retailer.

How do you graph vertical and horizontal shifts?
To graph a vertical shift, take the original graph and move it up or down on the y-axis. To graph a horizontal shift, take the original graph and move it left or right on the x-axis.
Vertical shifts can be graphically represented by taking the original graph and moving it up or down on the y-axis. This is accomplished by adding a constant value to every y-value in the equation. For example, if the equation is y = x + 2, shifting the graph up two units on the y-axis would change the equation to y = x + 4. Horizontal shifts can be graphically represented by taking the original graph and moving it left or right on the x-axis. This is accomplished by adding a constant value to every x-value in the equation. For example, if the equation is y = x + 2, shifting the graph two units to the right on the x-axis would change the equation to y = x - 2. When graphing vertical or horizontal shifts, it is important to remember that the overall shape of the graph remains the same, only the position of the graph changes.

how many 7 letter words can be made from mathisfun if each word must have 4 consonants and 3 vowels?
There are 5040 possible combination of 7 letter words using 3 vowels and 4 consonants.
We know that the word must have 4 consonants and 3 vowels. We have the following vowels in "mathisfun" : i, a, and u.
We have 7 letters that can be used as consonants: m,t,h,s,f,n.
First we need to find the number of ways to choose the 4 consonants out of 7 possible letters, which is 7C4 = 35.
Then we need to find the number of ways to arrange the 4 consonants and 3 vowels, which is 4!*3! = 144
Finally, we multiply those two values together: 35 * 144 = 5040.

The product of two consecutive natural numbers is 1. 5 times the square of the lesser number.
The two consecutive natural numbers are 2 and 3.
Let x be the smaller number. Hence, the larger number will be x + 1.
The product of these two consecutive natural numbers is x(x + 1). It is stated in the problem that this product is 1.5 times as big as the square of the smaller number, x². So we can set up the equation:
x(x + 1) = 1.5x²
Expanding and simplifying the equation:
x² + x = 1.5x²
0.5x² - x = 0
x(0.5x - 1) = 0
x = 0 or 0.5x - 1 = 0
x = 0 or 0.5x = 1
x = 0 or x = 2
The smaller number cannot be 0, so the solution for the smaller number is x = 2 and the larger number is x + 1 = 2 + 1 = 3.
Therefore, the two consecutive natural numbers are 2 and 3.
