The area of the given square is a 9.
According to the statement
We have to find that the area of the square.
So, For this purpose, we know that the
Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.
From the given information:
The square ABCD with the side AB=3cm. A 3cm B D C
Then
we know that the all the sides of the square all equals.
Then
AB=3cm = BC=CD=DA
Then
Area of the square = side*side
Area of the square = 3*3
Now,
The value of the Area of the square = 9.
So, The area of the given square is a 9.

Answer:
1/2
Step-by-step explanation:
When x = 20, y = 0
When x = 40, y = 10
When x = 60, y = 20
When x = 80, y = 30
When x = 100, y = 40
The slope is the change in y divided by the change in x.
First, find the change in x and y between any two points. We will use the first two points, (20, 0) and (40,10)
The change in x is 40 - 20 = 20
The change in y is 10 - 0 = 10
Divide the change in y by the change in x.
10 / 20 = 1/2
The slope is 1/2

Step-by-step explanation:
A cell phone company says that a fully charged battery lasts 14 hours. In reality, each battery behaves a little differently. For a large quantity of fully charged batteries, the mean length of time that batteries last is 14 hours, with a standard deviation of 1 hour. Assume that the lengths of time that battery charges last can be modeled by a normal distribution.
(a) What percent of fully charged cell phone batteries would be expected to last longer than 14 hours?
(b) What percent of fully charged cell phone batteries would be expected to last between 12 and 14 hours?
(c) What percent of fully charged cell phone batteries would be expected to last less than 15 hours?
(d) Would it be surprising if a fully charged cell phone battery lasted more than 17 hours? Explain why or why not.
The percentage is 50%
From the question we are told that
The mean is μ= 14 hours
The standard deviation is σ=1 hour
Generally on the normal distribution curve the mean divides the curve into two. with the half to the left of the mean (50% to the left )representing the percentage of the batteries that will last less than 14 hours and the area under the curve to the right (50% to the right)representing the percentage of batteries that will last longer than mean (14 hours )
Hence the percentage of the cell phone batteries that will be expected to last longer than 14 hours is 50%

The required angle measure for the condition of the proportion of angles m∠RPS is 212.35°.
Given that,
m∠QPS = 88
m∠RPS = 5x+34
m∠QPR=8x+15
The measure of the angle m∠RPS is to be determined.
The angle can be defined as the one line inclined over another line. the measure of an angle is measured in two units of degrees and in radiants.
Here,
m∠QPR = m∠QPS + m∠RPS
8x + 15 = 88 + 5x + 34
8x - 5x = 88 + 34 - 15
3x = 107
x = 107 / 3
x = 35.67
Now,
m∠RPS = 5x+34 = 5 * 35.67 + 34 = 212.35°
Thus, the required angle measure for the condition of the proportion of angles m∠RPS is 212.35°.

The figure with these coordinates are G'(3, -5), H'(2, 0), I'(0, -1) and J'(-1, -4) given below. Therefore, option C is the correct answer.
Given that the shape is reflected across the y-axis.
What is a reflection on the y-axis?The reflection of point (x, y) across the x-axis is (x, -y). When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is taken to be the additive inverse. The reflection of point (x, y) across the y-axis is (-x, y).
The coordinates of the given figure are G(-3, -5), H(-2, 0), I(0, -1) and J(1, -4)
When the coordinates of the figure GHIJ are reflected across the y-axis we get G(-(-3), -5), H(-(-2), 0), I(0, -1) and J(-(1), -4)
So, the coordinates are G'(3, -5), H'(2, 0), I'(0, -1) and J'(-1, -4)

An urn contains seven white balls and three green balls. A sample of three balls is selected at random. What is the probability that the sample contains two white balls and one green ball?
the probability that the sample contains two white balls and one green ball is 21/40.
In probability and statistics, an urn problem is an idealized mental exercise in which some objects of real interest (such as atoms, people, cars, etc.) are represented as colored balls in an urn or other container. One pretends to remove one or more balls from the urn; the goal is to determine the probability of drawing one color or another, or some other properties.

The ratio x:y is 3:7
Find the following in terms of x:
a) The HCF of (9y+x) and (3y+4x)
b) The LCM of (9y+x) and (3y+4x)
(a) The HCF of ( 9y + x ) and ( 3y + 4x ) is 11x
b) The LCM of ( 9y + x ) and ( 3y + 4x ) is 22x.
The ratio of x and y is given as:
x : y = 3 : 7
Then,
(x / y) = ( 3 / 7)
7x = 3y
(a) HCF of ( 9y + x) and ( 3y + 4x)
Now,
9y + x = 3(3y) + x
9y + x = 3(7x) + x
9y + x = 22x
And;
3y + 4x = 7x + 4x
3y + 4x = 11x
Now, the HCF of 22 and 11 is 11 because 22 = 2 × 11 and 11 = 11 × 1.
Therefore,
HCF of ( 9y + x ) and ( 3y + 4x ) is 11x.
(b) The LCM of (9y+x) and (3y+4x)
We know,
9y + x = 22x and 3y + 4x = 11x

Lorene plans to make several open-topped boxes in which to carry plants. She makes the boxes from rectangular sheets of cardboard from which she cuts out 5-in squares from each corner. The length of the original piece of cardboard is 10 in more than the width. If the volume of the box is 1875 in3, determine the dimensions of the original piece of cardboard.
The dimensions of the original shapes are 15 and 25 inches respectively
How to determine the dimensionsThe formula for volume of a rectangle is expressed as;
Volume = length × width × height
From the information given, we have;
Length = yWidth = y + 10Height = 5Volume = 1875Substitute the values
1875 = 5 × y × y + 10
Divide both sides 5
1875 / 5 = y(y + 10)
expand the bracket
375 = y² + 10y
y² +10y - 375 = 0
y² + 25y - 15y - 375 = 0
y(y + 25) - 15( y + 25) = 0
y= 15 or y = -25
If y = 15 Inches
Width = 15 + 10 = 25 Inches
Thus, the dimensions of the original shapes are 15 and 25 inches respectively
