Kristine would require at least 116ft of hardwood flooring for her room.

The answer is arrived at by using simple calculations of the area of a square - a polygon.

Note that there are missing portions on the shape of the floor. (See a more elaborate version attached).

The side labeled F = 12ft

The side labeled CDE comprises three sides: 8, 2, and 2 respectively. This is also equal to 12.

With this information, we can calculate the area of the square assuming it was full.

The area of a square is given as:

Length x Breadth or L²;

that gives us: 12 x 12 or 12² = 144ft.

Now we get the total actual area by removing the areas of the missing segments.

Section Ax and Ay is also a square. because the length and the breadth are equal.

hence the area of AxAy = 16ft.

We also have the area of the section labeled D,Dx. This section is a rectangle. The formula for the area of a rectangle is:

Length x Breadth.

Hence, we have

6 x 2 = 12ft.

Total area of missing sections are:

12 + 16 = 28ft.

The total area of the square less the missing areas is:

144 - 28 = 116ft.

Hence the total amount of Hardwood that Kristine would require in square ft is 116ft.

  -11x² +14x -11

Step-by-step explanation:

When one polynomial is subtracted from another, each of the terms of the subtrahend is subtracted from the corresponding term of the minuend.

  (-2x² +4x -10) -(9x² -10x +1)

  = (-2 -9)x² +(4 -(-10))x +(-10 -1)

  = -11x² +14x -11

The probability that the Islanders will win exactly three out of five games in a series against the Rangers is mathematically given as

P(x=3)=0.26367

Generally, the equation for the probability is mathematically given as

P(x=3)=nC3 (P)^r (q)^{n-r}

Therefore

P(x=3)=5C3 (0.75)^3 (0.25)^{5-3}

P(x=3)=10 (0.75)^3 (0.25)^{5-3}

P(x=3)=0.26367

In conclusion, The probability of the islander

Answer:

y is 12 degrees

x is 30 degrees

Step-by-step explanation:

If angle ABC is equal to angle MNC, that means 5y equals to 60 degrees. 60 divided by 5 equals 12. So, y equals 12 degrees

2x and 4x equals 180 degrees. So, 180 divided by 6 equals to 30. So x equals 30 degrees

Answer:

x = 30, y = 12

Step-by-step explanation:

2 similar equilateral triangles, each corner is 60 degrees.

2x = 60 degrees

divide by 2

x = 30 degrees

5y = 60 degrees

divide by 5

y = 12 degrees

This can be verified by checking 4x + 2x which gives you 180 degrees forming that straight line angle.

Answer:

Domain: x <= 4

Step-by-step explanation:

The domain is all the x's on the graph or all the x's that can be used in the equation. see image for graph. The graph exists coming from negative infinity (the left side of the graph) and then stops at the point where x is 4. So x must be less than 4 or equal to 4.

Algebraically, if x is bigger than 4, you get a negative number inside the radical (the square root symbol) and that is not allowed. Again we find that x has to be less than or equal to 4.

Step-by-step explanation:

the volume of a cylinder is as for any regular shaped object

ground area × height

here the ground area is a circle, so we get

pi×r²×h

with r being the radius (half the diameter), and h the height.

therefore,

pi×(2.7/2)²×10 = 3.14×1.8225×10 = 57.25552611... cm³

so, the first option is correct.

is there any answer choices

Answer:

12 560 cubic feet

Step-by-step explanation:

radius of circular cross section = 20ft/2 = 10ft

Area of circular cross section = πr²

                                                 = 3.14 x 10 x 10

                                                 = 314 square feet

Volume of cylindrical tank =  314 ft² x 40ft

                                            = 12 560 ft³

Answer:

L < 5.25yd

Step-by-step explanation:

We can think of Mrs. Klein's composting area as a rectangle, and the formula for finding the area of a rectangle is Base * Height = Area (B*H=A)

Let's just say for the sake of solving the problem that they say that area of the garden had to be exaclty 6 square feet. Because the area must be 6sqft (sqyd = square yards) then we can enter 6 into our formula.

B*H=A now equals B*H=6

They also tell us that the width (which is a stand-in for height) is [tex]1\frac{1}{7}[/tex] so we can enter that in our formula as well

B*H=6 now is [tex]B*1\frac{1}{7} =6[/tex] and now we just have one unknown... the B (base)

And since [tex]B*1\frac{1}{7} =6[/tex] then [tex]6/1\frac{1}{7} =B[/tex]

Thus,

[tex]6yd / 1\frac{1}{7} = 5.25yd[/tex]

And because the question said that the area must be less then 6sqyd, then the length can be anything less then 5.25yd.

Thus,

L < 2.25

Answer:

32 degrees

Step-by-step explanation:

The angle supplementary with the 122 degree angle measures 180-122=58 degrees.

So, the triangle has interior angles of f, 90, and 58 degres.

Since the angles in a triangle add to 180 degrees, f+180-90-58=32 degrees
