the percent of change in the area is 300 percent .

Step-by-step explanation:

Rectangle is the closed shaped polygon with 4 sides. Opposite sides of the rectangle are equal. when the length and the width of the sandbox are doubled the percent of change in the perimeter is 100 percent and the percent of change in the area is 300 percent.

ANSWER:

STEP-BY-STEP EXPLANATION:

We have that the equation of a line in its slope and y-intercept form is the following:

Now, when two equations are perpendicular, the slope of both are opposite, that is, the product between them is equal to -1, like this:

We replace the values of the point (-9, 6) and the slope to calculate the value of the y -intercept:

Therefore, the perpendicular equation that also passes through the point (-9,6) is:

Now, when two lines are parallel, the slope is the same, therefore we calculate directly that it passes through the point (-9, 6)

therefore, the equation of the line that is parallel to this line and passes through the point (-9, 6) is:

When Q = {all perfect squares less than 30} and p={ all odd numbers from 1 to 10) Q ∩ P = { 1, 9}

Set theory simply means the branch of mathematical logic that deals with sets, that can be described as collections of objects.

It should be noted that perfect squares are the numbers that can be divided to give same number.

Q = {all perfect squares less than 30}. This will be 1, 4, 9, 16, 25

P ={ all odd numbers from 1 to 10}. This will be 1, 3, 5, 7, and 9.

In this case, the common numbers to set of P and Q are 1 and 9.

Therefore, the numbers are 1 and 9 since they're common to both sides.

Answer:

34

Step-by-step explanation:

The value would be 34

The simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years is $ 1,350.

It is given in the question that:-

Principal = $15,000

Time period = 3 years

Interest rate = 3 %

Total interest paid by Lori, if the loan was amortized = $ 704.

We have to find the simple interest Lori would pay if the loan was not amortized and the entire loan was paid at the end of 3 years.

We know that,

Simple interest = (Principal*Rate*Time)/100

Hence,

Simple interest = (15000*3*3)/100 = $ 1350.

The point-slope form of a line is:

y = mx + b

where m is the slope and b is the y-intercept

Replacing with point (1, -8) and m= -9, we get:

-8 = (-9)(1) + b

-8 = -9 + b

-8 + 9 = b

1 = b

Then, the equation is:

y = -9x + 1

60 ml of the 55% solution is required to get the desired solution.

A unique kind of homogenous mixture made up of two or more substances is called a solution.

Let  x ml of 55% solution is taken.

therefore alcohol = 0.55x ml

water = 0.45x ml

Now it is added to 10% 75 ml solution.

Alcohol = 10% of 75 = 7.5ml

Water = 67.5 ml

New mixture = 75 + x

Alcohol = 30% of (75+x) = 22.5 + 0.3x

Therefore 22.5 + 0.3x = 7.5 + 0.55x

or, x = 60 ml

Therefore 60 ml of the 55% solution is required.

Step-by-step explanation:

A proportional relationship is of the form y=kx for some constant k.

From the point (60, -20), we know that k = -1/3.

128 = 2^7 is a power of 2

27 = 3^3 is a perfect cube

=======================================================

Explanation:

This is something you'd find through trial and error.

The powers of 2 are

2, 4, 8, 16, 32, 64, 128, 256, ...

We double each value to get the next one.

The largest power of 2 that is smaller than 155 is 128

155-128 = 27 which is a cube number since x^3 = 3^3 = 27 as you've shown in the screenshot.

If the result of 155-128 wasn't a perfect cube number, then you'd have to try the next largest power of 2 (which is 64) and work your way down the list.

----------------------

Or you could work with the list of perfect cubes

1, 8, 27, 64, 125, 216, ...

Each value is of the form x^3 where x is a whole number.

Let's pick the largest perfect cube that is under 155, and subtract it

155-125 = 30 which isn't a power of 2 (refer to the list above)

Then try 155-64 = 91 which isn't a power of 2 either

Keep moving down the list until reaching 155-27 = 128 which is a power of 2 since 2^7 = 128

A potential advertiser for marketing purpose, after performing a test at 0.05 level of significance fails to reject the null hypothesis leads to the conclusion that there is not sufficient evidence at the 0.05 level of significance to say that the percentage is less than 68%.

Hypothesis testing refers to a statistical inference approach used to determine if the available data sufficiently support a particular hypothesis. Hypothesis testing enable researchers to make probabilistic statements about population parameters. In the given case, the null and alternative hypothesis regarding the publisher’s claim state:

The null hypothesis stated that the 68% or more of the readers own a Rolls Royce. H0: p ≥ 0.68

The alternate hypothesis states that less than 68% of the readers own a Rolls Royce. H1: p < 0.68

As the advertiser failed to reject the null hypothesis, it was accepted and thus, 68% or more of the readers own a Rolls Royce. It is concluded that there is not sufficient evidence at the 0.05 level of significance to say that the percentage is less than 68%.

Two positive integers whose product is 24,999,999 are 4999 and 5001

Given

The product of two numbers should be 24,999,999.

The positive difference should be small

There are many ways to obtain those two numbers but an easiest way would be taking the square root of the given number and making decision by trial and error.

This may take few iterations but this is the optimal way to solve.

Square root of 24,999,999 is 4999.99

Hence try multiplying a number less than and a number equal to 4999.99.

Eventually we will reach to a conclusion 4999 x 5001 whose product is 24,999,999.

The difference of the numbers is 5001 - 4999 = 2

Hence the positive difference is small.

Hence the two numbers are 4999, 5001.

Answer:

A = 34

B = 29.4

C = 58.8

D = 34

The equations are e = 18+12t and a = 45+9t

Adrian will be father along in the book after 4 days. She will be 15 pages ahead of Ethan

Ethan's page number at the beginning of the month = 18

Adrian's page number at the beginning of the month = 45

Pages read by Ethan each day = 12 pages

Pages read by Adrian each day = 9 pages

Let e represent the page of the book that Ethan is on at the end of t days into the month. Let a represent the page of the book that Adrian is on at the end of t days into the month.

Formulating the equation we get the following:

e = 18 + 12t

a = 45 + 9t

Finding the page number of both Ethan and Adrian after 4 days by substituting the values in the equations we get:

e = 18+12(4)

e = 66

a = 45 + 9(4)

a = 81

Answer:

  18 m/s²

Step-by-step explanation:

You want Dean's acceleration when his speed changes from 10 m/s to 100 m/s in 5 seconds.

Acceleration is the rate of change of velocity, the change in velocity divided by the corresponding change in time:

  a = ∆v/∆t

  a = (100 m/s -10 m/s)/(5 s) = (90 m/s)/(5 s) = 18 m/s²

Dean's acceleration is 18 m/s².

__

Additional comment

Both velocity and acceleration are vector quantities. They have both magnitude and direction.

We assume the given speeds are in the same direction, so the direction of the velocity vector does not change. The acceleration is in that same direction.

The perimeter of rectangle with the given dimensions is 6x+6.

Given that the dimensions of rectangle are 2x and x+3.

We need to find the perimeter of the given rectangle.

The overall length of the outline determines a shape's perimeter in two dimensions. We add the lengths of all four corners of a rectangle to find its perimeter. Rectangle perimeter is calculated using the formula perimeter of a rectangle = 2(l + w), where l is the rectangle's length and w is its width.

We know that, the perimeter of rectangle = 2(Length + Width)

Now, perimeter

=2(2x+x+3)

=2(3x+3) (Add like terms)

Using distributive property multiply 2 to 3x and 2 to 3

We get 6x+6

Therefore, the perimeter of rectangle with the given dimensions is 6x+6.

Move the y = x2 graph 10 units to the right, then 8 units up.

There are y= x²——————> y = (x-10)²+8

The fact that

A point (x,y) in f(x) shifts up by d as a result of f(x)+d, a

and

f(x-e) ----> a point (x, y) in f(x) becomes a——————-> (x+e, y)——> shift right by  in this issue

d=8

e=10

Therefore,

Shift the y = x2 graph.

8 up, 10 to the right

The law is

(x,y)———-> (x+10,y+8)

The vertex in the equation y=x2--------- (0,0)

The vertex in the equation y = (x-10)2+8 (10,8)

so

(10,8)------> (0,0)----------> (x+10,y+8)———> (10,8)------> (0+10,0+8)

As a result, shift the y = x2 graph 8 units up and then 10 units to the right.
