find the value of x​

Answer:

The area of the circle is 2520 cm²

Step-by-step explanation:

The area of an arc is given by the following formula:

arc area = pi*r²(angle/360)

In this case we have the area and the angle and we want to find r, so we have:

210 = pi*r²*(30/360)

210 = pi*r²*(1/12)

210*12 = pi*r²

pi*r² = 210*12

r² = 2520/pi

r = sqrt(2520/pi)

r = 28.3221

The area of the circle that has this arc is given by:

area = pi*r²

area = pi*(28.3221)² = 2520 cm²

Answer:

1/9

Step-by-step explanation:

[tex]3^{-2}[/tex] =1/3²=1/9

Answer:

$562.43

Step-by-step explanation:

V(3) = [tex]500 ( 1 + \frac{0.04}{1} )^{3} \\500 (1.04)^{3}[/tex]

     = 562.43

The interest is $562.4 compounded annually.

Compound interest is defined as interest paid on the original principal and the interest earn on interest of principal.

P = $500

r = 4%

t = 3 years

CI = P( 1+ r/100)ⁿ

CI = 500 ( 1+ 4/100)³

CI = 500 ( 1+ 0.04)³

CI = 500 ( 1.04)³

CI = 500 ( 1.1248)

CI = 562.4

Hence, the interest is $562.4 compounded annually.

Answer:   6:15___{2:5}

The reduce it by dividing by 3.

6/3 =2.

15/3 =5.

= {2:5}

Answer:

63 students said yes.

Step-by-step explanation:

105/5= 21

21*3= 63

Answer:

C = 63

Step-by-step explanation:

We know that there are 105 students, so we will take the total amount of students and multiply by 3/5, since this is the probably rate is which say yes. in other words --> 105 * 3/5 = 63

Step-by-step explanation:

Volume of a square based pyramid = [tex]\frac{1}{3}a^{2}h[/tex] where;

a² is the base area of the pyramid since it is square shaped

h is the slant height.

Given Base area = 144m² and Volume = 384m³, on substituting this values given in the formula we have;

[tex]384 = \frac{1}{3}*144h \\cross\ multiplying\ \\384*3=144h\\h = \frac{384*3}{144} \\h = \frac{1,152}{144}\\ h = 8m[/tex]

The slant height of the pyramid is 8m

Answer:

Next coat sold as medium: 68/190 (35.79%) Rounded to the nearest hundredth) or reduced fraction form of 34/95.

Step-by-step explanation:

Red Medium: 21/58 ( 36.21%)

Navy Medium: 22/66 (33.33%

Tan Medium: 25/66 (37.88%)

Since it's asking for the probability that the next coat is a medium, no matter the color, we add in all numbers and divide it by the added medium from all three colors.

Next coat sold as medium: 68/190 (35.79%) Rounded to the nearest hundredth) or reduced fraction form of 34/95.

Answer:

The coefficient is 6

Step-by-step explanation:

The coefficient is the number before the variable

In this case, the variable, or the unknown value, is x.

The number before x is it's co-efficient.

6x

The number before the x is 6

Hope this helps :)

Answer:

6 is the coefficient

Step-by-step explanation:

Coefficient: multiples the variable to some power.

 like for example

3x^2

3 is the coefficient

or

Ax^n

A is the coefficient

Answer:

The value also increases

Answer:

Step-by-step explanation:

Here we have the length of the hypotenuse (16) and that of the vertical leg (11).  The cosine function inputs this data:

            adjacent side                11

sin x = -----------------------  =  ----------------  =  0.6875

              hypotenuse                 16

We find x using the arccos function:  arccos 0.6875 = 0.81 radians or

Step-by-step explanation:

Answer:

The volume of the figure is 20,925.0mm^3.

Step-by-step explanation:

Firstly we know that the Diameter = 14mm and Height = 136mm.

Area of Circle = 3.14xR^2    Radius = Diameter / 2

Area of Circle = 3.14x7mm^2 = 153.86mm

Volume = 153.86 x 136 = 20,924.96

Then round, to get 20,925.0

Let me know if this is helpful

Answer:

Volume : ( About ) 20925 mm^3

Step-by-step explanation:

1. If the diameter of this cylinder is 14 mm, the radius ⇒ 14/2 ⇒ 7 mm

2. Now knowing the radius, it would be most convenient to solve for the Base, which is in fact a circle. As we can see, the general Volume of a 3-dimensional figure is Base * height, so this will be helpful. Applying πr^2, Base Area ⇒ π * ( 7 )^2 ⇒ π * 49 π ⇒ 153.86 mm^2

This means that the Volume would be ⇒ Base Area * height ( where height is 138 mm ) ⇒ 153.86 mm^2 * 136 mm ⇒ 20924.96 mm^3

Answer ( Volume ) : ( About ) 20925 mm^3

Step-by-step explanation:

Answer:

15 sqrt(2) =c

Step-by-step explanation:

We can use the Pythagorean theorem

a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse

The legs are 15 and the hypotenuse is the diagonal

15^2 + 15^2 = c^2

2 * 15^2 = c^2

Take the square root of each side

sqrt(2 * 15^2 )=sqrt( c^2)

sqrt(2) sqrt(15^2) = c

15 sqrt(2) =c

Answer: 15[tex]\sqrt{2}[/tex] (b)

Step-by-step explanation:

You can separate a square into two different 45-45-90 degree triangles.

Where x = 15, and the diagonal would be the hypotenuse.

So, here you can use the Pythagorean Theorem to find the hypotenuse to use 45-45-90 triangle theorem where they hypotenuse is always x times [tex]\sqrt{2}[/tex]

So, the diagonal would be 15[tex]\sqrt{2}[/tex]

Answer:

30 degrees

Step-by-step explanation:

A circle is 360 degrees

It is divided into 12 parts

So...

360 divided by 12

equals

30!

Answer: I think its 30 not 100 percent sure

Answer:

1) 30 units³

2) 18 units³

Step-by-step explanation:

1) The formula for volume is v = height x length x width

The height of the first object is 2, the length is 5, and the width is 3.  2 x 5 x 3 is 30, so the volume is 30 units ³.

2) Use the same formula, v = h x l x w

The height is 3, the length is 3, and the width is 2.

3 x 3 x 2 = 18

So the volume is 18 units³.

Note: Find each of the values by counting the number of squares
