What fraction of the square is the green triangle?

Answers

Answer:

1/4

Step-by-step explanation:

Answer:

7/32

(btw thats the simplified version....look at the bottom for non-simplified if you didnt need it simplified)

Step-by-step explanation:

first count how many squares there are in total

its 8 by 8 so in total there are 64!

now there is the green triangle.....

count all the whole squares in it = 10

now count all the half squares (little triangles in it)= 8

Now if you put those little triangles together it would make one small unit square so it is 4 of all

10 + 4 = 14

So there is a Total of 14 unit squares in the green triangle

Fraction Time......

now lets take 14/64 and simplify it

that would be 7/32

We cant make it any more simplified now if you werent looking for the simplified version the your answser would be 14/64

I hope this was the answser you were looking for!! Mark Me Brainliest ;)

Find the surface area of a sphere with radius 5 using the formula SA=4pir2
Leave answer in terms of n
A. 75 pi units squared
B. 100 pi units squared

Answers

Answer:

B. 100 pi units squared

Step-by-step explanation:

Find the surface area of a sphere with radius 5 using the formula SA=4pir²

Leave answer in terms of π = pi

From the question

The formula for the Surface Area if a square = 4 × pi × r²

r = 5

Hence,

Surface Area of a Sphere = 4 × pi × 5²

= 100 pi units squared

Option B is the correct option

What is length of BW using what you know? DONT GIVE ME A LINK JUST ANSWE PLEASEE (will give brainlist)

Answers

Answer:

The length of BW is [tex]105\sqrt{2}[/tex], or about 148.49.

Step-by-step explanation:

For this problem, we will assume that the figure is a square. We will call the figure "Figure BOWL".

Because figure BOWL is a square, we know that the lengths of each sides of the square are equal, so the length of each side is 105.

Notice that the BW, OB, and WO make a triangle. We'll call it triangle BOW. Since figure BOWL is a square, we know that angle BOW is 90°, and so triangle BOW is a right triangle.

Since triangle BOW is a right triangle, we can solve for BW using the Pythagorean theorem, [tex]a^{2} + b^2 = c^2[/tex]. "a" and "b" are the legs of the triangle, while "c" is the hypotenuse of the triangle.

In triangle BOW, the legs are OB and WO, while the hypotenuse is BW.

Plug in the values for the equation and solve.

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

[tex]OB^2 + WO^2 = BW^2[/tex]

[tex]105^2 + 105^2 = BW^2[/tex]

[tex]11,025 + 11,025 = BW^2[/tex]

[tex]22,050 = BW^2[/tex]

[tex]\sqrt{22,050} = BW[/tex]

We can either use the estimated value, or the exact simplified value of [tex]\sqrt{22,050}[/tex].

Here is the exact simplified value:

[tex]\sqrt{22,050} = \sqrt{25 * 882} = \sqrt{25 * 9 * 98} = \sqrt{25 * 9 * 49 * 2} = \sqrt{5^2 * 3^2 * 7^2 * 2} = (5 * 3 * 7)\sqrt{2} = 105\sqrt{2}[/tex]

BW = [tex]105\sqrt{2}[/tex]

For the estimated value, just use a calculator:

[tex]\sqrt{22,050}[/tex] ≈ 148.49

BW ≈ 148.49

The mean of a data set is 124. The mean absolute deviation is 38. What is the greatest possible number within the mean absolute deviation?

Answers

Answer:

Infinity

Step-by-step explanation:

The given parameters are;

The mean of the data, μ = 124

The mean absolute deviation = 38

The mean absolute deviation is given as follows;

[tex]Mean \ absolute \ deviation = \dfrac{\sum \left | X - \mu \right |}{N} = 38[/tex]

Where;

μ = Mean

X = Score

N = The number of scores

Therefore;

[tex]N \times 38 = \sum\limits_{i = 1}^N \left | X - \mu \right |} = \sum\limits_{i = 1}^N \left | X -124 \right |}[/tex]

When there are an infinite number of terms, N = ∞, the greatest possible number within the mean absolute deviation is therefore also infinite

[tex]\infty \times 38 = \sum\limits_{i = 1}^{\infty} \left | X - \mu \right |} = \infty[/tex]

[tex]Greatest \ possible \ value \ for \left | X - \mu \right |} = \infty[/tex]
