Answer:

Two shapes are similar when they have the same shape while their sizes may be the same or different

Therefore, two similar shapes are shapes that have a relationship such that the dimensions of one of the shapes can be obtained from the dimensions of the other shape by multiplying by a scale factor

All circles have the same shape and are defined by their center and radius

Given circle with center at 'x' and radius 'r' and circle with center 'y' and radius 's', then there exist a scale factor a = s/r such that we have;

r × a = s

Where a = s/r, we get;

r × s/r = s

We can therefore, obtain a circle with with the same size as the circle with center 'y' and radius 's' by multiplying the radius of the circle with center at 'x' and radius 'r' by a

Therefore the circle with center at 'x' and radius 'r' is similar to the circle with center 'y' and radius 's'

Answer:

38bs

Step-by-step explanation:

multiply the number of students that each bus can hold by the no of buses 38s×b=38bs

Answer:

A - 36 in.

b - 8

Step-by-step explanation:

A - You marked all of it right! 10 + 10 + 10 + 6

B - The teeth are only on half of the circle that hit the chain. 10 inches of chain for the big wheel, so 1/2 of 10 is 5. Same thing for the little wheel, 1/2 of 6 is 3, and 5+3 = 8, so about 8!

Answer:

$41.04

Step-by-step explanation:

8% = 0.08

38(0.08) = 3.04

$3.04 is the tax for the jeans. Now we just have to add it to the price.

38 + 3.04 = $41.04

Answer:

$41.04

Step-by-step explanation:

0.08 (the tax converted from percentage) x 38 (initial cost) = 3.04(tax amount)

38(initial amount) + tax amount (3.04) = 41.04

the cost after tax is $41.04

understand now? To convert 8% to a decimal just move the decimal to the left twice (because we’re representing out of 100%)

Answer:

455.1111 feet²

Step-by-step explanation:

Given that :

Array of mosaic = 8 * 8 color square tiles

Length of each tile = 2 2/3 feets long

The length of mosaic = length per tile * Number of array :

2 2/3 feets * 8 = 21.3333 feets

This corresponds to the side length of the mosaic

The Area of the whole mosaic:

Using the area of square formula = s²

Where, s = side length

s = 21.33333 ft²

s² = 21.33333²

s² = 455.1111²

Answer:

[tex] 4,220.16 \: {units}^{3} [/tex]

Step-by-step explanation:

Diameter of cone = 24 units

Radius of cone (r) = 24/2 = 12 units

Height of cone (h) = 28 units

[tex]V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ = \frac{1}{ 3} \times 3.14 \times {(12)}^{2} \times 28 \\ \\ = \frac{1}{3} \times 3.14 \times 144 \times 28 \\ \\ = 3.14 \times 1,344 \\ \\ = 4,220.16\: {units}^{3} [/tex]

Para calcular isto, temos que dividir 28 por 4, que dá 7. Neste contexto, 7 é 1/4 de 28, o número de pontos marcad .

Step-by-step explanation:

Answer:

The cost of the aquarium was $38

Step-by-step explanation:

I got 60% of 100 and it was 60 so it was $40 but then the sales tax was $2 so I subtracted and got 38

The total cost of the aquarium is the sum of the marked down price and

the sales tax.

The total cost of the aquarium is $42

Reasons:

The known information are;

Original price of the aquarium = $100

The marked down percentage of the aquarium = 60%

The sales tax = 5%

[tex]Mark \ down = \dfrac{Difference}{Current \ selling \ price} \times 100[/tex]

[tex]60 \% = \dfrac{Difference}{100} \times 100[/tex]

Which gives;

The difference in sale = $100 - Marked down price = $60

Marked down price = $100 - $60 = $40

The marked down price = $40

The tax is applied to the marked down price, therefore, we get;

Sales tax = 5% × $40 = $2

The total cost = Marked down price + Sales tax

The total cost of the aquarium = $40 + $2 = $42

Answer:

C. It is likely

Step-by-step explanation:

Given

See attachment for diagram

For the square.

Let

[tex]Length = L[/tex]

So, the area is:

[tex]Area = Length^2[/tex]

[tex]A_1=L^2[/tex]

The side length of the square equals the diameter of the circle.

So:

[tex]diameter (d) = L[/tex]

The radius is:

[tex]r = \frac{1}{2}d[/tex]

[tex]r = \frac{1}{2}L[/tex]

The area is:

[tex]Area = \pi r^2[/tex]

[tex]A_2 = \pi * (\frac{1}{2}L)^2[/tex]

[tex]A_2 = \pi * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{7} * \frac{1}{4}L^2[/tex]

[tex]A_2 = \frac{22}{28} L^2[/tex]

The likelihood that a point will be common to the square and the circle is:

[tex]Pr = \frac{A_2}{A_1}[/tex]

[tex]Pr = \frac{\frac{22}{28} L^2}{L^2}[/tex]

[tex]Pr = \frac{22}{28}[/tex]

[tex]Pr = 78.57\%[/tex]

The above probability is greater than 50% but less than 100%.

Hence, it is likely

Answer:

C. Likely

Step-by-step explanation:

all the points are in the circle so it's likely to choose a point inside the circle
