Answer:

To find the area of the extension, I'm going to find the total area (patio and extension) and subtract the patio.

Total area:  length  =  1.5 + 6.25 + 1.5  =  9.25     height  =  1.5 + 6.25  =  7.75

   Total Area  =  9.25 x 7.75  =  71.6875

Area of the patio  =  6.25 x 6.25  =  39.0625

Area of the extension  =  Total Area - Area of the patio  =  71.6875 - 39.0625  =  32.625

Area covered by one box of tiles:  25 x 0.25 x 0.25  =  1.5625

Number of boxes needed:  32.625 / 1.5625  =  20.88  =  21 boxes

Answer:

(d). [tex]\frac{152}{377}[/tex]

Step-by-step explanation:

sin² β + cos² β = 1

cos (α + β) = cos α cos β - sin α sin β

cos α = √(1 - [tex]\frac{400}{841}[/tex] ) = 21 / 29

cos β = 12 / 13

sin β = √(1 - [tex]\frac{144}{169}[/tex] ) = 5 / 13

sin α = 20 / 29

cos (α + β) = [tex]\frac{21}{29}[/tex] × [tex]\frac{12}{13}[/tex] - [tex]\frac{20}{29}[/tex] × [tex]\frac{5}{13}[/tex] = [tex]\frac{152}{377}[/tex]

Answer:

if its not a perfect square(like u can't square it) then its irrational

Answer: $60

Step-by-step explanation:

Given that:

Amount left after purchasing sneakers = $12

$12 is equivalent to 20% of the initial starting amount

Let starting amount = x

20% of x = $12

0.2x = $12

Divide through by 0.2

0.2x / 0.2 = $12 / 0.2

x = $60

Hence, starting amount before buying sneakers is $60

Answer:

The set of transformations has been performed on triangle ABC is dilation by a scale factor of 2 followed by reflection about the x-axis

Step-by-step explanation:

Let us write the vertices of Δ ABC

∵ Vertex A = (-2, -1)

∵ Vertex B = (0, 0)

∵ Vertex C = (1, -3)

Let us Write the vertices of Δ A'B'C'

∵ Vertex A' = (-4, 2)

∵ Vertex B' = (0, 0)

∵ Vertex C' = (2, 6)

Let us find the scale factor k between the x-coordinates of the points and their images.

∵ -4 = k (-2) ⇒ Divide both side by -2

∵ [tex]\frac{-4}{-2}[/tex] = [tex]\frac{-2k}{-2}[/tex]

∴ 2 = k

∴ The scale factor of a dilation is 2

∵ The signs of the y-coordinates of the images are the opposite of

    the signs of the y-coordinates of the points

∴ The triangle is reflected about the x-axis

∴ The set of transformations has been performed on triangle ABC

   is dilation by a scale factor of 2 followed by reflection about the x-axis

where is the table??? pls send it

the awnser is

4.0/5. 7. calculista

The slope is [tex]\frac{dy}{dx}[/tex] which means it's 100/40 which is 2.5 or 5/2

[tex]d[/tex] has a full time job in defining difference :D

So basically the slope is defined as the difference in the [tex]y[/tex] over the difference in the [tex]x[/tex]

Answer:

5/2

Step-by-step explanation:

To find slope, we can see how much to rise and run from one point to another. In this example, the slope would be 5/2 because you rise 5 and run 2 to get to a different point.

Hope this helps! Have a nice day ^^

Answer:

the height is 0.6367 so the surface area is 68.55

Surface area is the total area of an object's outer facing surfaces. The total surface area is calculated by adding all the areas on the surface: the areas of the object's base, top, and lateral surfaces (sides).

You can use r2 to replace B (area of the base), which is a type of prism with a circular base, and 2r to replace p. (perimeter of the base). The surface area of a cylinder is calculated as SA=2r2+2rh.

Therefore,

The cylinder's surface area is 264 cm2 (approximately)

3 unit is the cylinder's radius.

The cylinder's height is 18 units

To locate:

Area of contact

Having said that,

Cylinder surface area = 2r(h + r)

replacing the necessary values,

Surface area is equal to

2 x 22 /7 x 3 × 3( Plus 4)

Surface area equals 264/7 (7)

Surface area equals 1848/7

264 cm2 is the surface area.

The cylinder's surface area is 264 cm2 (about).

(9×6/2) × 12 = 324

Explination:

The easiest way to understand what you're doing is to find the area of the base first, then extend it upwards to find the volume using height. Hence the equation: b×h=v

So how do we find the base of a triange? Remember that every single triangle can be calculated as a square, then cut in half. So 9 × 6 / 2 = 27 cm2

The next step is to calculate the volume using the height of the figure. 27 × 12 = 324 cm3

**remember to use the correct units, since area and volume are different.

Answer: 2n^2+3n-4

1st differnce is 3, 7, 11, 15

2nd differnce is 4

so its 2n^2

we compare it to teh 2n^2 sequence

2 8 18 32 50

-1 2 9 20 35

difference is 3, 6, 9, 12,15

so it is 3n-4

Answer:

8.75 or 8 3/4

Step-by-step explanation:7

The numbers in 7 divided by 4/5 are labeled below:

7 = whole number

4 = numerator

5 = denominator

To make it a fraction form answer, you multiply the whole number by the denominator and make the result the new numerator. The old numerator becomes the new denominator:

7 x 5

4

 =    

35

4

Thus, the answer to 7 divided by 4/5 in fraction form is:

35

4

To make the answer to 7 divided by 4/5 in decimal form, you simply divide the numerator by the denominator from the fraction answer above:

35 / 4 = 8.75

The answer is rounded to the nearest two decimal points if necessary.

35/4 is an improper fraction and should be written as 8 3/4.

While there are many quadratic equations using -6 and 5 as roots, the most simple would be the basic (x+6)(x-5)=0, or simplified, x² + x - 30 = 0.

Using these roots, all you have to do is make both sides of the equation and even both sides of the multiplied pre-product to equal 0. If using this format, x has to be equal to -6, and 5.
