because the front row has 15 and the back row shud also have 15 (because it is a cuboid)

.°. 15 × 2 = 30

.°. no. of cubes = 30 cubes

Answer:

30

Step-by-step explanation:

The easiest way to find this is to find the volume of the cube, instead of counting them one by one.

So, volume = l x w x h = 5 x 2 x 3 = 30 units^2

This units ^2 is the number of cubes you have.ie. 30

Step-by-step explanation:

The Factor Theorem says that if f(a) = 0, then (x -a) is a factor.

To check if any of these binomials are factors, we evaluate the function at the opposite of the binomial's constant. The results show that these are factors:

1:27

Step-by-step explanation:

I will use solve in terms of pi

Know that Original volume * scale factor cubed = new volume.

The scale factor is 3 and 3^3 is 27,

Therefore the ratio is 1:27

Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. The correct option is D.

Scaled figures are zoomed in or zoomed out (or just no zoom) versions of each other. They have scaled versions of each other, and by scale, we mean that each of their dimension(like height, width etc linear quantities) are constant multiple of their similar figure.

So, if a side of a figure is of length L units, and that of its similar figure is of M units, then:

[tex]L = k \times M[/tex]

where 'k' will be called a scale factor.

The linear things grow linearly like length, height etc.

The quantities which are squares or multiple linear things twice grow by the square of the scale factor. Thus, we need to multiply or divide by k²

to get each other corresponding quantities from their similar figures' quantities.

So the area of the first figure = k² × the area of the second figure

Similarly, increasing product-derived quantities will need increased power of 'k' to get the corresponding quantity. Thus, for volume, it is k cubed. or

The volume of the first figure = k³ × volume of the second figure.

It is because we will need to multiply 3 linear quantities to get volume, which results in k getting multiplied 3 times, thus, cubed.

Given that the diameter of sphere A is 2 units, it is dilated by a scale factor of 3 to create sphere B. Therefore, the diameter of sphere B is,

Diameter of sphere B = 3 × Diameter of sphere A

                                    = 3 × 2 units

                                    = 6 units

Now, the ratio of diameters of the sphere and the volume of the sphere can be written as,

[tex](\dfrac{\text{Diameter of sphere A}}{\text{Diameter of sphere B}})^3 = \dfrac{\text{Volume of sphere A}}{\text{Volume of sphere B}} \\\\\\(\dfrac{2}{6})^3 = \dfrac{\text{Volume of sphere A}}{\text{Volume of sphere B}}\\\\\\\dfrac{\text{Volume of sphere A}}{\text{Volume of sphere B}} = \dfrac{1}{27}[/tex]

Hence, the correct option is D.

Answer:

10,583 flexible cubes

9915 rigid cubes

Step-by-step explanation:

The equation for the surface area of a square pyramid is area of base plus perimeter of base multiplied by the slant height

Surface area = A + 1/2·p·s

The volume of the pyramid = 1/3×A×h

Where:

A = Area of the base = 20 × 20 = 400 ft²

h = The height of the pyramid = √((slant height)² - ((base side length)/2)²)

h = √(80² - (20/2)²) = 30·√7

The volume of the pyramid = 1/3*400*30·√7 = 4000·√7 ft³ = 10,583.005 ft³

If the cubes are flexible, approximately 10,583 cubes

For rigid cubes we have

Given that the height of the pyramid = 30·√7

The slope of the pyramid = 30·√7/10 = 3·√7

So an increase in height of 1 foot gives a reduction in width of 2/(3·√7)

The bottom can hold 400 cubes

The next layer can hold 19×19 = 361

3rd 361

4th 361

5th 324

6th 324

7th 324

8th 324

9th

Continuing, we get a total of about 9915 rigid cubes in the pyramid.

The correct equation of the translated function, g(x) is,

⇒ g(x) = (x + 4)² 6

A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).

here, we have,

Given that:

The function is,

,⇒ f (x) = x²

Here, f(x) has vertex point is (0,0)

and g(x) vertex point is (-4,6)

Hence, The general form of equation with vertex is

⇒ y = a (x - h)² + k

where (h, k) are the vertex.

So, the equation of g(x) form is

⇒ g(x) = (x + 4)² + 6

The correct option is B, The elevation is a nonlinear function because it does not have a constant rate of change.

A linear equation is an equation in which each term has at max one degree. Linear equation in variable x and y can be written in the form y = mx + c.

Linear equation with two variables, when graphed on the cartesian plane with axes of those variables, give a straight line.

Given that the table shows data collected by a runner. A three-column table with 7 rows. The first column shows Time in minutes. The second column shows Distance in miles. The third column shows Elevation in meters.  

Therefore, if we assume the time as the independent function, therefore, the other two variable must change with respect to time.

Also, if the two functions are needed to be linear than the change in the variable must be constant and should be with respect to time.

Hence, if the statement about the scenario represented in the table is true is B, The elevation is a nonlinear function because it does not have a constant rate of change.

A = {(2, −2), (5, −5), (−2, 2), (−5, 5)}

B = {(4, 2), (4, −2), (9, 3), (9, −3)}

A is a function, it has a one to one correspondence

B is not a function. The x point 2 goes to 2 different y  values, so it does not have a one to one relationship

a. Only A

answer A. 0.5

Step-by-step explanation:

hello

as A and B are independent P(B/A)=P(B) =0.5

in short, the information provided by the event A does not impact at all the event B. so knowing A or not does not impact the probability of B.

you can use the formula as well P(B/A)=P(A and B) / P(A)=(P(A)xP(B))/P(A)=P(B)

Answer:

The constant of proportionality for this relationship is 6. The price of 6 bags of candy is $36.

Step-by-step explanation:

Assuming that bag of candies is x and price is y, then the constant of proportionality will be how much y increases for every increase of x by 1.

When x increases by 1, y increases by 6. So, the constant of proportionality for this relationship is 6.

Using this, to find the value of y when [tex]x=6[/tex], we can multiply 6 by 6 because for every time x increases by 6, y increase by [tex]6\cdot6[/tex] times.

[tex]6\cdot6=36[/tex]

So when x = 6, y = 36.

Answer:

e. 2x - 7y = 31.

Step-by-step explanation:

If you want a line parallel to the equation, the line must have the same slope.

2x - 7y = 9

-7y = -2x + 9

y = 2/7x - 9/7

You are looking for a line where the slope is 2/7.

a. Slope is 7/2.

b. Slope is -7/2.

c. Slope is 7/2.

d. Slope is...

y + 2 = 3/4x + 3

y = 3/4x + 1

Slope is 3/4.

e. Slope is -2/-7, which is 2/7. Just make sure to check whether it passes through (5, -3) by substituting those points into the equation.

2 * 5 - 7 * -3 = 31

10 --21 = 31

10 + 21 = 31

Answer:

The sum of x and y: x+y

5 times a is added to b: 5a+b

The sum of x and y is multiplied by 3: 3(x+y)

6 is added to the number b: 6+b or b+6

b and 4ab are unlike terms.

Step-by-step explanation:

Hope this helps!

The sum of x and y means you have to add x+y. Also, sum is the answer to an  addition problem. So, if you add x+y, you would get the sum.

5 times a is added to b means 5 times a or 5a, and once you have the product, you add it to b, so 5a+b.

The sum of numbers x and y is multiplied by 3 You have  the sum of x and y which is x+y, then you multiply it by 3. So, you can write it as 3 times the sum of x+y, so 3(x+y).

When you are adding, you use the addition sign.

you are adding 6 to b, so b+6.

b and 4ab are unlike terms because they both don't the same two letters. Yes, they share the letter b, but they don't share the letter a, so ther are unlike terms.

Answer:

the first and fourth quadrants

Step-by-step explanation:

We have that the time found hours is given on the x-axis and that the temperature is represented on the y-axis.

Let's first analyze time:

Time cannot be negative, therefore, the x coordinate cannot be negative therefore, for the x axis, we can use the first and fourth quadrants

Second let's analyze the temperature:

The temperature can be negative, therefore, the coordinate and can be positive or negative therefore, that for the y axis, we can use all four quadrants.

If we combine the two previous conditions, we can deduce that we can only use the first and fourth quadrants to represent the required data.
