The radius of a circle is 4 inches. How would you calculate the circumference?
A. π · 4² in.²
B. 2 · π· 4 in.
C. π · 8² in.²
D. 2· π · 8 in.

Answer:

The width would be 3.33 feet. I got this answer by dividing 20 by 6. The area of a Rectangle is (Length times Width) so 6 times 3.33 = 20.

Step-by-step explanation:

The area of the shaded part of the figure is; 114.3ft²

From the task content:

The area of the square is;

The area of the quarter circle is;

A(quarter circle) = 50.3ft².

Ultimately, the area of the shaded part of the figure is; 50.3ft² + 64ft² = 114.3ft².

Answer:

3x + 6y

Step-by-step explanation:

so the perimeter is 12x + 8y and a side is 4x-2y so that means that side and the side across is 8x-4y so you put it all to one side to get 6x +12y then divide that by 2 to find 1 side so the side is 3x + 6y

Answer: no because that is like

Given:

[tex]X = {0,1,2,3,4} \\ Y = {2,4,6,8,10,12} \\ Z = {3,6,9,12,15}[/tex]

So,

[tex]X∪Y = (0,1,2,3,4) \: ∪ \: (2,4,6,8,10,12) \\ = > (0,1,2,3,4,6,8,10,12)[/tex]

[tex]X∩Z = (0,1,2,3,4) \: ∩ \: (3,6,9,12,15) \\ = > (3)[/tex]

[tex](X∪Y)∩Z = (0,1,2,3,4,6,8,10,13) ∩ (3,6,9,12,15) \\ = > (3,6)[/tex]

Using the generic set operations, we will see that:

For two given sets A and B, we define:

A ∪ B as the union of the two sets, this is the set that contains all the elements from both A and B.

A ∩ B is the intersection of A and B, this set contains only the common elements of A and B.

Now we want to complete the given table:

1) X U Y is the union of sets X and Y (we do not repeat elements) so this is equal to:

{0, 1, 2, 3, 4, 6, 8, 10, 12}

2) X ∩ Z is the intersection of X and Z, the only common element between these sets is 3, then:

X ∩ Z = {3}

3) (X U Y)∩ Z

Is the set of the common elements between:

X U Y = {0, 1, 2, 3, 4, 6, 8, 10, 12}

Z = {3, 6, 9, 12, 15}

The common ones are:

3, 6, and 12, then we have:

(X U Y)∩ Z = {3, 6, 12}

Answer:

x = -3

y = 7

Step-by-step explanation:

4y + 2 = 30

x - 4y = -31

Simplify the first equation by subtracting 2 from both sides:

4y = 28

Divide both sides by 4

y=7

Plug 7 in for y to solve for x:

x - 4(7) = -31

x - 28 = -31

Add 28 to both sides

x=-3

(x,y)=(-3,7)

Answer:

the value of X is 70

Step-by-step explanation:

The new value would be the starting value x 1 + interest rate:

New value = starting value x 1.06

The new value is 530:

530 = starting value x 1.06

Find the starting value by dividing the new value by 1.06:

start value = 530/1.06

Start value = 500

Answer: $500.
explain reasoning: because the bond is only one year old you would multiply the value of the bond by the interest rate and add the interest amount to the bond to get $530.

Answer:

35 degrees

Step-by-step explanation:

Assuming B is the center of the circle, the measure of arc AC is 70 degrees since the measure of a central angle is equal to the measure of the arc it intercepts.

This means that by the inscribed angle theorem, which states that the measure of an inscribed angle is half the measure of the arc it intercepts, the measure of the desired angle is 35 degrees.

Answer:

Heptagon = 84 ft²

Octagon  = 186 yd²

Triangle = 48√3 m²

Step-by-step explanation:

[tex]\textsf{area of a regular polygon}=\dfrac12ap[/tex]

where:

Heptagon

a = 5.0 ft

p = 33.6 ft

⇒ area = 1/2 x 5.0 x 33.6 = 84 ft²

Octagon

a = 7.5 yd

p = 8 x 6.2 = 49.6 yd

⇒ area = 1/2 x 7.5 x 49.6 = 186 yd²

Triangle

Formula for the apothem of an equilateral triangle :

[tex]a=\dfrac{s}{2\sqrt{3}}[/tex]  where [tex]s[/tex] = side length

a = 4, so:

[tex]4=\dfrac{s}{2\sqrt{3}}[/tex]

[tex]\implies 8\sqrt{3}=s[/tex]

Now we know the side length, we can calculate the perimeter (p):

p = 3 x 8√3 = 24√3

⇒ area = 1/2 x 4 x 24√3 = 48√3 m²

Answer: Your answer is 55% = 11 / 20

Hope this helps!

Answer:

11/20

Step-by-step explanation:

Step 1: We represent the given number as a fraction by dividing it by 100.

Hence, we write it as 55/100.

Step 2: Simplify the fraction by using common factors of numerator and denominator.

Now, 55% can be written as 55 / 100.

On simplifying the above fraction:

55 / 100 = 11 / 20 [Dividing numerator and denominator by their greatest common factor, that is 5.]

Therefore, 55% can be represented as 11/20 in fractional form.

x = 3

Step-by-step explanation:

x^5 = 243

Take the fifth root of each side which is the same as raising each side to th 1/5 power. Also, 243 = 3^5.

x^5 = 3^5

(x^5)^(1/5) = (3^5)^(1/5)

x = 3

Answer:

3

Step-by-step explanation:

x^5= 243

I guess we're looking for x

so what we do is just find the fifth root of 243

and that's 3

Answer:

81.6 inches squared

Step-by-step explanation:

The formula for calculating all parallelograms is Area+=base*height.

The height is given to you, 6.8, the base of the figure is also given, 12.

Now all you have to do is to multiply.

That would get you to 81.6.

(When asked for area of parallelogram, the length of any line other than the height and base is not needed)
