The total area of all six sides that will be painted on the wooden cube is 96 square centimeters.

First, we need to understand that each cube has six faces or sides, which are all squares of the same size. When we paint the cube, we will be painting all six sides of it. Therefore, we need to find the total area of all six sides that will be painted.

To calculate the area of each side, we need to know the length of the side. You mentioned that the wooden blocks are cubes, so each side will have the same length. Let's say the length of each side is 4 cm.

Now, we can calculate the area of one side of the cube by squaring the length of the side. In this case, the area of one side will be:

Area of one side = (length of side)²

= (4 cm)²

= 16 cm²

Since there are six sides to each cube, we can find the total area of all six sides by multiplying the area of one side by six:

Total painted area = 6 x Area of one side

= 6 x 16 cm²

= 96 cm²

Step-by-step explanation:

( 11 * x ) + 2     where 'x' is a number

The two triangles are congruent since they have equal angles and equal sides.

Congruent triangles are two triangles that have exactly the same size and shape.

In other words we can say that they have the same angles and the same side lengths.

So when two triangles are congruent, all of their corresponding parts including the angles and sides are equal.

For the given triangles

The missing value of angle C = 180 - (18 + 110) = 52⁰

The missing value of angle F = 180 - (18 + 52) = 110⁰

So it is obvious that the two triangles are congruent since they have equal angles and equal sides.

Step-by-step explanation:

First, you need to cancel out the 2 by subtracting 2 from both sides. Then, we divide both sides by -5. And finally, we remove the absolute value.

The formula for T in terms of m and p is: [tex]T = 15m + 40p[/tex]

We are given that number of marbles in each small bag is 15, and Rosanna sells m small bags, so the total number of marbles in the small bags is: [tex]15m[/tex]

Also given that number of marbles in each large bag is 40, and Rosanna sells p large bags, so the total number of marbles in the large bags is:[tex]40p[/tex]

So, total number of marbles that Rosanna sells is the sum of the marbles in the small bags and in the large bags will be addition of both values which will give us: [tex]T = 15m + 40p[/tex].

The solution is,  2.5 miles per hour was her walking rate in miles per hour.

We know that,

Speed is measured as distance moved over time.

The formula for speed is speed = distance ÷ time.

To work out what the units are for speed, you need to know the units for distance and time.

In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

Speed = Distance/ Time.

Here, given that,

Bao walked 15 miles in 6 hours.

so, we get,

in 6 hours = 15 miles

so, in 1 hour = 15 / 6 miles

                    =2.5 miles

Hence, The solution is,  2.5 miles per hour was her walking rate in miles per hour.

The correct answer is,

C. 60(x - 3) = 45x.

This equation is based on the information that the 45 expensive wood costs $3.00 more than the 60 cheap wood. In other words, if the price of the 60 cheap wood is x, the price of the 45 expensive wood is x + 3.

Since,  Algebra involves working with numbers, equations, and variables to solve real-world problems and understand abstract relationships.

Now, To solve this equation, we must use algebra and solve for x.

First, we multiply both sides of the equation by 4/5. This gives us:

48x + 36 = 45x

-36 = 3x

Finally, we divide left side of the equation by 3, giving us the final solution:

x = -12

Therefore, the price of the 60 cheap wood is $12, and the price of the 45 expensive wood is $15.

that is, 60 (x - 3) = 45x

This equation shows the correct relationship between the two types of wood that the contractor purchased.

Using the radioactivity formula given to find out the concertation and the half life of the material. In this case, we are given the function A(t) = 600e^(-0.05t), which represents the quantity of the material at time t.

Let A(0) be the initial amount of the material, then we have,

[tex]A(0) = 600e^{-0.05(0)} = 600[/tex]

To find the half-life, we need to solve for t when A(t) = A(0)/2:

A(t) = A(0)/2

[tex]600(e^{-0.05t}) =\frac{600}{2}[/tex]

Taking natural logarithm,

The solution to the system of linear equation is:

x = 10 2/3, y = 5

The correct option is the last option   10 2/3, 5

From the question, we are to solve the given system of linear equation.

The given system of linear equations is

1/2x + 1/3y = 7

1/4x + 2/3y = 6

Multiply the first equation by 2

1/2x + 1/3y = 7      × 2

x + 2/3y = 14

Subtract the second equation from the resulting equation

     x + 2/3y = 14

- 1/4x + 2/3y = 6

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

3/4x = 8

Multiply both sides of the equation by 4/3

4/3 × 3/4x = 8 × 4/3

x = 32/3

x = 10 2/3

Substitute the value of x into

x + 2/3y = 14

To determine y

(10 2/3) + 2/3y = 14

32/3 + 2/3y = 14

Multiply through by 3

32 + 2y = 42

Subtract 32 from both sides

32 - 32 + 2y = 42 - 32

2y = 10

Divide both sides by 2

2y / 2 = 10 / 2

y = 5

Hence, the solution is:

The values of θ for different conditions were calculated with the help of trigonometric functions.

Given that;

The difference in length of a spring on a pogo stick from its non-compressed length when a teenager is jumping on it after θ seconds can be described by the function,

f (θ) = 2 sin θ + √ 2

Hence, We can simplify as;

A) Function is,

f (θ) = 2 sin θ + √ 2

f (θ) = 2 sin θ + √ 2 = 0

2 sin θ + √ 2 = 0

2 sin θ = -  √ 2

sin θ = - 1/√2

θ = nπ ± π/4

Where, n = 1, 3, 5, 7, ...

So, At θ = nπ ± π/4 pogo stick's spring will be equal to its non compressed length.

2) If the angle was doubled, the function will look like this,

f (θ) = 2 sin 2θ + √ 2

f (θ) = 2 sin 2θ + √ 2 = 0

2 sin 2θ + √ 2 = 0

2 sin 2θ = -  √ 2

sin 2θ = - 1/√2

θ = nπ/2 + π/8

Where, n = 1, 3, 5, 7, ...

n = 1;

θ = π/2 + π/8

θ = 5π/8

n = 2;

θ = π + π//8

θ = 9π/8

Hence, Solutions are, 5π/8, 9π/8, ...

3) g (θ) = 1 - cos²θ + √2

g (θ) = sin²θ + √2

sin²θ + √2 = 2 sinθ + √2

sin²θ - 2 sinθ= 0

sinθ (sinθ - 2) = 0

sinθ = 0

θ = nπ

Where, n = 1, 3, 5, 7, ..

So, θ = nπ , the lengths of springs from the original pogo stick and the toddler's pogo stick are equal.

By substituting the values of values of height and volume in the above formula we'll get the required value of the radius.

[tex]:\implies [/tex] 180π = πr² 11.25

[tex]:\implies [/tex] 180π = r² × 11.25 π

[tex]:\implies [/tex] 180π/11.25 π = r²

[tex]:\implies [/tex] 16 = r²

[tex]:\implies [/tex] r² = √16

Hence, Radius of the cylinder is 4 meters.

To find when the two equations 65x + 20 = y and 730 + 35x = y will meet on the graph, we need to solve for the value of x that satisfies both equations.

We can begin by setting the right-hand sides of the two equations equal to each other:

65x + 20 = 730 + 35x

Subtracting 35x from both sides, we get:

30x + 20 = 730

Subtracting 20 from both sides, we get:

30x = 710

Dividing both sides by 30, we get:

x = 23.67

Now that we have found the value of x that satisfies both equations, we can substitute it into either equation to find the corresponding value of y. Let's use the first equation:

y = 65x + 20

y = 65(23.67) + 20

y = 1539.55

Therefore, the two equations will meet on the graph at the point (23.67, 1539.55).

Step-by-step explanation:

To solve this problem, we can use the multiplication principle of counting, which states that if there are k choices for one task and m choices for a second task, then there are k x m choices for both tasks combined.

In this case, we can apply this principle to each shelf of books, as there are different numbers of books on each shelf. For the first shelf, there are 12 choices, for the second shelf there are 18 choices, for the third shelf there are 25 choices, and for the fourth shelf there are 30 choices.

To choose one book from each shelf, we need to multiply the number of choices for each shelf together, which gives us:

12 x 18 x 25 x 30 = 16,200,000

Therefore, there are 16,200,000 ways to choose three books, one from each shelf, in the library.

The total number of ways of choosing three books , one from each shelf is given by A = 162,000 ways

The number of ways of selecting r objects from n unlike objects is given by combinations

From (1)

x + y = 26

x = 26 - y

Substitute x = 26 - y into (2)

20x + 25y = 592.50

20(26 - y) + 25y = 592.50

520 - 20y + 25y = 592.50
