There are 10 numbers who are perfect squares.

When an integer is multiplied by the same integer, the resultant number is known as a square number. For example, when we multiply 5 × 5 = 52, we get 25. Here, 25 is a square number. Square numbers are always positive, they cannot be negative because when a negative number is multiplied by the same negative number, it results in a positive number.

The properties of square numbers are listed below which helps to identify them easily.

Given:

2 and 140

Now, the perfect squares are:

√4=2

√9=3

√16 =4

√25=5

√36=6

√49=7

√64=8

√81=9

√100=10

√121=11

Please find the complete question in the attached file.

For the random condition:

If other regular fees have been chosen at random, I'd claim I'm satisfactory.

State of autonomy:

Truly content, since the 44 daily fees represent less than 10% of the total population of daily payments, the community must have more than 440 daily fees.

In the  Normal Condition:

Since the sample size of 44 is 30 or more, the distribution of the sample means is roughly Normal (as per the total probability theorem).

Answer:

[tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]

Step-by-step explanation:

The equation of a line is y = mx + b

Where:

First, let's find what m is, the slope of the line.

Let's call the first point you gave, (-3,1), point #1, so the x and y numbers given will be called x1 and y1.

Also, let's call the second point you gave, (2,-1), point #2, so the x and y numbers here will be called x2 and y2.

Now, just plug the numbers into the formula for m above, like this:

[tex]m = -\frac{2}{5}[/tex]

So, we have the first piece to finding the equation of this line, and we can fill it into y=mx+b like this:

[tex]y=-\frac{2}{5}x + b[/tex]

Now, what about b, the y-intercept?

To find b, think about what your (x,y) points mean:

Now, look at our line's equation so far: [tex]y=-\frac{2}{5}x + b[/tex]. [tex]b[/tex] is what we want, the -[tex]-\frac{2}{5}[/tex] is already set and x and y are just two 'free variables' sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the two points (-3,1) and (2,-1).

So, why not plug in for x and y from one of our (x,y) points that we know the line passes through? This will allow us to solve for b for the particular line that passes through the two points you gave!

You can use either (x,y) point you want. The answer will be the same:

See! In both cases, we got the same value for b. And this completes our problem.

The equation of the line that passes through the points  (-3,1) and (2,-1) is [tex]y=-\frac{2}{5}x-\frac{1}{5}[/tex]

Answer:

680. 55 feets

Step-by-step explanation:

From the diagram, distance from lighthouse to buoy = x

Angle from top of lighthouse to buoy = (90 - 10) = 80°

Using the trigonometric relation :

Tanθ = opposite / Adjacent

Opposite = x

Adjacent = 120

Tan 80 = x / 120

5.6712818 = x / 120

x = 5.6712818 * 120

x = 680. 55 feets

The horizontal distance d that the top of the tower is off vertical is equal to the 190.32feet.

We have given that,

The leaning tower of Pisa in Italy has a height of 183 feet and is 4∘ off vertical.

We have to determine the horizontal distance d that the top of the tower is off vertical. round your answer to the nearest tenth of a foot.

The horizontal displacement of a projectile depends upon the initial horizontal speed and the time of travel. The vertical displacement of a projectile.

The horizontal distance d that the top of the tower is off vertical.

183 times 1.04=190.32.

Therefore the horizontal distance d that the top of the tower is off vertical is equal to the 190.32feet.

Answer: 7/18

Step-by-step explanation:

Number of customers at Eva's boutique = 90

Number of customers who wore a size extra-large = 35

The probability that a randomly selected customer wore a size extra-large will be:

= Number of customers who wore a size extra-large / Number of customers at Eva's boutique

= 35 / 90

= 7/18

Therefore, the probability that a randomly selected customer wore a size extra large is 7/18.

10 months

Step-by-step explanation:

If it takes 2 months to do 1/5th, it will take 4 months to do 2/5, 6 months to do 3/5, 8 months to do 4/5, and 10 months to do 5/5 or in other words the whole thing.

The remaining work will take 8 month.

Algebra is the branch of mathematics that represents problems in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression.

Given:

As,  1/5 th of the work has been completed in 2 months.

let the total time taken to complete the work is 'x' month.

1/5 * x = 2

x= 5*2

x=10 month

Hence, remaining work will take (10 - 2) = 8 month.

Answer:

Rectangle Perimeter = 26

Step-by-step explanation:

Rectangle ABCD , Length = parallel horizontal sides are AB & CD, Breadth = parallel vertical sides = BC & AD

AB segment joining A (0,0) - B (0,9) = 9 units. CD joining C (4, 9) & D (4,0) = 9 units. So, Length = 9 units

BC segment joining B (0,9) - C (4,9) = 4 units. AD joining A (0,0) - D (4,0) = 4 units. So, Breadth = 4 units

Perimeter of rectangle = 2 (Length + Breadth)

= 2 (9 + 4)

= 13 x 2 = 26

Hope this helps !

Answer:

See attachment :)

Step-by-step explanation:

The given equation is in slope-intercept form, which lists the slope and the y-intercept of the line.

Slope-intercept form is  [tex]y=mx+b[/tex], where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept. The y-intercept, 2, is a point on the y-axis where the line intersects with the axis. So, we can graph the given intercept on the y-axis, (0,2).

The slope, [tex]m[/tex], is [tex]\frac{4}{5}[/tex]. The slope is the rise of the line over the run, or [tex]\frac{rise}{run}[/tex]. For this equation, then, we rise 4 units and run 5.

We'll start from the y-intercept, a point we know will be on our line. From this point, move up 4 units, and right 5. A negative slope would run  to the left, but this is a positive line, so the run will go to the left. Now, we are on the point (5,6). From this point, we can repeat this [tex]\frac{rise}{run}[/tex].

A few of the following points are (10,10), (14,15), and (18,20). Now, draw a line connecting these points. This line is a graph of our equation.
