Answer:724
Step-by-step explanation: Let us go through trail and error method.
Question: Need to find N, so that 2020+ N should be a perfect cube, as well as a multiple of 56.
2744 is the first number we get after 2020 and it is a cube of 14. ___ equation -01
Let us divide, 2744 with 56.
i.e., 2744/56= 49. ___ equation -02
As per 1st and 2nd equation 2744 meets with the condition. And we can consider it as 2020+ N.
i.e., 2020+N= 2744
N= 2744-2020
Therefore; N= 724.
Answer:
724,
Step-by-step explanation:
14^3 = 2744 is the next perfect cube > 2020.
2744 / 56 = 49.
So that fits the requirements in the question.
So N = 2744 - 2020
= 724,
Given these facts, determine how many cans of paint you would need to buy to paint 2 walls.
1st wall: 20 ft. x 8ft.
2nd wall: 40ft. x 8ft.
1 can will cover 200 square feet of wall.
You will need 3 cans of paint to cover the two walls
How many cans of paint will you need?
We know that 1 can will cover 200 square feet of wall.
And here we have 2 walls, let's find the total area of these walls.
wall 1 is 20ft by 8ft, then its area is:
A = 20ft*8ft = 160ft^2
wall 2 is 40t by 8 ft, then its area is:
A' = 40ft*8ft = 320ft^2
The total area is:
160ft^2 + 320ft^2 = 480ft^2
The number of cans of paint needed is given by the quotient between the total area and the area that each can cover.
N = 480ft^2/200ft^2 = 2.4
But we can't have a 0.4 of a can, so we should round to the next whole number, which is 3.

A substance is tested and has a ph of 7.0. how would you classify it? a. a strong acid b. a strong base c. a weak acid d. neutral
A substance is tested and has a Ph of 7.0. It would be a weak acid.
The correct option is (c) a weak acid .
What is the nature of substance if the pH is less than 7?
Acidity is defined as pH below 7. More than 7 pH is considered basic. Each whole pH number below 7 is ten times more acidic than the next higher value since the pH scale is logarithmic. For instance, pH 4 is 100 times (10 times 10) more acidic than pH 6, while pH 5 is ten times (10 times) more acidic than pH 4.What is pH?
The pH scale determines how acidic or basic water is. The range is 0 to 14, with 7 representing neutrality. Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7. In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.Learn more about pH

How to do 8+(-3)+(-2) three diffrent ways on a number line?
3 ways of computing the sum on the number line are:
Start at 8, then move 2 units to the left, then move 3 units to the left.Start at -3, then move 8 units to the right, then move 2 units to the left.Start at -2, then move 3 units to the left, then move 8 units to the right.How to do the sum in three different ways on a number line?
Here we have the sum:
8 + (-3) + (-2)
The first way of doing the sum in a number line is starting on the first number, which is 8.
Then, we move 3 units to the left, to the 5.Then, we move other 2 units to the left, to the 3.Now, we also can think the sum as:
(-3) + 8 + (-2)
So now we can start at the value -3, then move 8 units to the right, and then 2 units to the left.
Or think the sum as:
(-2) + (-3) + 8
So we start at -2, then we move 3 units to the left, and finally 8 units to the right.
So the different ways of computing the sum on a number line depends on where we start.

Given that, Jean loads a ream of paper 500 sheets into the tray of her photocopier she has 23 sheets and need 20 copies each sheet.
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Number of sheets used = 23×20
= 460
Remaining sheets = 500-460

What are the restricted values for x2−3x−2−4y⋅2x−2−xy2+2y2?
The restricted values in (x^2 - 3x - 2)/-4y * (2x - 2)/(-xy^2 + 2y^2) are x ≠2 and y ≠ 0
How to determine the restricted values for the function?The complete question is added as an attachment
The equation is given as:
(x^2 - 3x - 2)/-4y * (2x - 2)/(-xy^2 + 2y^2)
Set the products of the denominators to 0
-4y * (-xy^2 + 2y^2) = 0
Split the equation
-4y = 0 or (-xy^2 + 2y^2) = 0
Remove the bracket
-4y = 0 or -xy^2 + 2y^2 = 0
Divide both sides by -4 in -4y = 0
y = 0
Factor out y^2 in -xy^2 + 2y^2 = 0
y^2(-x + 2) = 0
This means that y^2 = 0 or -x + 2= 0
This gives y = 0 or -x + 2 = 0
Solve for x in -x + 2 = 0
x = 2
Hence, the restricted values in (x^2 - 3x - 2)/-4y * (2x - 2)/(-xy^2 + 2y^2) are x ≠2 and y ≠ 0

Answer:

Step-by-step explanation:
The mean absolute deviation(MAD) of a data set is given by the formula
[tex]$ MAD =\frac{1}{n} \sum_{i=1}^n |x_i-\bar{x}|$[/tex]
n = number of data set values. Here n=7

A 1.05x because adding $5 to the cost of the shoes is the same as multiplying the cost by 1.05
B 1.05x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05
C x(0.05) because the cost of the shoes can be factored out
D 1.5x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.5
The expression which represents Daria's total cost is; 1.05x because adding 5% to the cost of the shoes is the same as multiplying the cost by 1.05
PercentageAmount paid for shoes = $xTax = 5%Total cost = x + (5% of x)

At a school 45% of the students are boys; 30% of the boys and 40% of the girls play soccer. What percentage of the whole school plays soccer?
The percentage of the whole school that plays soccer is 35.5%
How to determine the percentage of the whole school plays soccer?The percentage of the boys is given as
Percentage boys = 45%
This means that the percentage of the girls is given as
Percentage girls = 55%
Also, from the question, we have:
30% of the boys and 40% of the girls play soccer
So, the percentage of the whole school that plays soccer is
P = Boys * Percentage Boys + Girls * Percentage Girls
This gives
P = 45% * 30% + 55% * 40%
Evaluate the product
P = 13.5% + 22%
Evaluate the sum
P = 35.5%
Hence, the percentage of the whole school that plays soccer is 35.5%
