614.125 = 8.5^3

The correct value of the length of a side = 2¼ ft

Answer:

area of the whole mosaic = 182.25 ft²

Step-by-step explanation:

We are told it has a 6 x 6 array of different colour square tiles.

Which means it has 6 x 6 = 36 square tiles.

Area of square = L²

Where L is length of side

Now, since length of one tile is 2¼ ft long.

Thus, area of one square tile = (2¼)²

= 81/16 ft²

Since there are 36 tiles,

Thus ;

Total area ; 81/16 x 36 = 182.25 ft²

Final answer:

The area of one tile in the mosaic is 5.0625 ft², and because there are 36 tiles in the mosaic, the total area is 182.25 ft². Mosaics are an ancient and durable art form requiring significant skill to create, especially when using small tesserae.

Explanation:

Francesca's window store created a mosaic for the community center that consisted of a 6 × 6 array of square tiles. To find the area of the whole mosaic, we need to calculate the area of one tile and then multiply it by the total number of tiles in the array.

Firstly, we have been given that each tile is 2 1/4 ft in length. Since the tiles are square, the area of one tile will be (2 1/4 ft) × (2 1/4 ft). In decimal form, 2 1/4 ft is equal to 2.25 ft. The area of one tile is therefore:

2.25 ft × 2.25 ft = 5.0625 ft²

Since there are 36 tiles (6 tiles in each direction), the total area of the mosaic will be:

5.0625 ft² × 36 = 182.25 ft²

Mosaics require considerable skill and time to create, especially when they employ tiny tesserae. As seen throughout history, mosaics have been used to decorate many surfaces, such as those in Francesca's example. The durability and artistic value of mosaics continue to make them a popular choice for artistic expression in structures like the community center.

Answer:

m = 3

Step-by-step explanation:

First, distribute the 5 to the values inside the parentheses.

6 + 5m + 5 = 26

Combine like terms: 5m + 11 = 26

Then, you want to isolate the variable so you subtract 11 from both sides because what you do on one side must be done to the other.

5m + 11 - 11 = 5m

26 - 11 = 15

5m = 15

Then divide both sides by 5.

5m / 5 = m

15 / 5 = 3

m = 3

Answer:

m=3

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation

The arc measure BDC that subtend the angle at the center P of the circle is  213 degrees

The arc measure of angle BDC is as follows;

AC and BD are the diameter of the circle.

∠BPD ≅ ∠APD

Therefore,

4k + 159 = 2k + 153

4k - 2k = 153 - 159

2k = -6

k = -6 / 2

k = -3

4(-3) + 159 = 147°

∠BPD ≅ ∠APD = 147°

Hence,

∠BPA ≅ ∠CPD = 33°

arc BDC = 33 + 147 + 33 = 213 degrees

Step-by-step explanation:

Given the information:

Use the pytagon theory to find the hypotenuse of the triangle

[tex]a^{2} + b^{2} = c^{2}[/tex]

<=>[tex]((3a)^{3}) ^{2} + ((4a)^{3}) ^{2} = c^{2}[/tex]

Answer:

The amount earned is $327.75

Step-by-step explanation:

If the workwr working for 5h gets $71.25, then his working for 1 hour could be said to be x.

5h = $71.25

1h = x; cross multiplying would result in

x= [tex]\frac{($71.25*1)}{5h}[/tex]

x= $14.25 which is the pay for 1h

Therefore for 23 h the worker would earn

23* 14.25 = $327.75

Step-by-step explanation:

The probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 is given by the z-score and P ( 0.37 < x < 0.39 ) = 16.32 %

The relationship between a value and the mean of a set of values is expressed numerically by a Z-score. The Z-score is computed using the standard deviations from the mean. A Z-score of zero indicates that the data point's score and the mean score are identical.

The Z-score is calculated using the formula:

z = (x - μ)/σ

where z: standard score

x: observed value

μ: mean of the sample

σ: standard deviation of the sample

Given data ,

Let the probability that a sample chosen at random has a proportion of registered voters who vote between 0.37 and 0.39 be P ( A )

Now , the mean of the sample μ = 0.38

The standard deviation σ = 0.0485

And , z₁ = 0.37 and z₂ = 0.39

So , P ( A ) = P ( 0.37 < x < 0.39 )

On simplifying , we get

z = (x - μ)/σ

z₁ = ( 0.37 - 0.38 ) / 0.0485

z₁ = -0.206

z₂ = ( 0.39 - 0.38 ) / 0.0485

z₂ = 0.206

So , P ( 0.37 < x < 0.39 ) = P ( -0.206 < z < 0.206 )

On further simplification of the z-score , we get

P ( 0.37 < x < 0.39 ) = 0.5816045 - 0.4183955

P ( 0.37 < x < 0.39 ) = 0.1632

Hence , the probability is 16.32 %

8 x 3.14 = 25.12

Therefore, the circumference of the circle is 25.12 kilometers.

The circumference of a circle with a diameter of 8 kilometers is 25.12 kilometers.

The formula to calculate the circumference of a circle is C = πd, where d is the diameter. In this case, the diameter is given as 8 kilometers. So, we can substitute this value into the formula:

C = 3.14 x 8 = 25.12 kilometers

Answer:

290 cm sq.

Step-by-step explanation:

We can approximate this irregular figure as a trapezoid.

We know the area formula for a trapezoid is A = (1/2)*(base1 + base2)*height

A = (1/2)* (22 cm + 36 cm) * (10 cm)

A = (1/2) *( 58 cm)*10 cm

A = 29 cm * 10 cm

A = 290 cm sq.

Answer:

The function g(x) = (x + 1)² is represented by the graph Y

Step-by-step explanation:

The question presents the graph of the function x² above

Therefore, for a function f(x) = x² at x = 0 y = 0

For function g(x) = (x + 1)² when x = 0 g(x) = 1  Satisfied by graph W and Y

Also we have g(x) =  (x + 1)² = x² + 2·x + 1  or g(x) = f(x) + 2·x + 1

We find the minimum of the graph by differentiating and equating to zero as follows;

[tex]\frac{\mathrm{d} (x + 1)^{2}}{\mathrm{d} x} = 2x +2 = 0[/tex]

Therefor, the minimum is at x = -1 satisfied by only graph Y

Hence the graph that represents the function g(x) = (x + 1)² is the graph Y.

Answer: 3,017.5 cubic centimeters.

Step-by-step explanation:

Hi, to answer this question we have to calculate the volume of each cd case:

Volume of a rectangular prism= length x width x height

Replacing with the values given:

V = 14.2 x 12.5 x 1 = 177.5 cubic centimeters.

Since there are 17 cases in the stack, we have to multiply the volume one case by 17.

177.5 x 17 = 3,017.5 cubic centimeters.

Answer:

sqrt(292) = JK

The approximate answer is

17.08800749 = JK

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2

We know the legs JL and LK and are looking for the hypotenuse JK which is opposite and L which is the right angle

6^2 + 16^2 = JK ^2

36 +256 = JK ^2

292 = JK^2

Take the square root of each side

sqrt(292) = sqrt( JK^2)

sqrt(292) = JK

The approximate answer is

17.08800749 = JK

Answer:

2sqrt(73)

Step-by-step explanation:

Since angle L is 90, JK is the hypotenuse

JK² = 6² + 16²

JK² = 292

JK = 2sqrt(73)
