Answer:

x = 16, y = 8[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{8}{x}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

x = 16

----------------------------------------------------------

Using Pythagoras' identity in the right triangle

y² + 8² = 16²

y² + 64 = 256 ( subtract 64 from both sides )

y² = 192 ( take the square root of both sides )

y = [tex]\sqrt{192}[/tex] = [tex]\sqrt{64(3)}[/tex] = 8[tex]\sqrt{3}[/tex]

Answer:

8 sides

Step-by-step explanation:

THE QUESTION IS NOT COMPLETE, SO A QUESTION OF THE SAME TYPE

Find the number of sides of a regular polygon if exterior angle of the polygon is 45°?

NOTE:

Sum of the exterior angles of any regular polygon is known as (360°)

But from the question,

Each exterior angle is given as( 45°)

Number of sides of a regular polygon can be computed as

(360°/Each exterior angle)

Then substitute the give value of exterior angle, we have

= (360°/45) = 8 sides

x= -4

y= -7

Answer:

Volume of air inside the cylinder = 71.6 cm³

Step-by-step explanation:

Step 1: Determine height and radius of the cylinder

Since the three tennis balls fits in closely into the cylindrical container, the height of the cylinder is equal to the sum ofnthe diameters of the three balls.

Also, the radius of the cylinder is equal to the radius of the tennis balls.

Height of cylinder = 3 × 4.5 cm = 13.5 cm

Radius of cylinder/balls = diameter of ball / 2 = 4.5 cm / 2 = 2.25 cm

Step 2: Determination of the volume of the cylinder

Volume of a cylinder = πr²h

π = 22/7; r = 2.25 cm; h = 13.5 cm

Volume of cylinder = 22/7 × (2.25 cm)² × 13.5 cm

Volume of cylinder = 214.8 cm³

Step 3: Determining the volume of the three balls

Volume of a sphere = 4πr³/3

Volume of three balls = 4πr³/3 × 3 = 4πr³

Volume of the three balls = 4 × 22/7 × (2.25 cm)³ = 143.2 cm³

Step 4: Determining the volume of air

Volume of air inside the cylinder = Volume of cylinder - volume of the three balls

Volume of air = 214.8 cm³ - 143.2 cm³ = 71.6 cm³

Therefore, volume of air inside the cylinder = 71.6 cm³

Answer:

5/8

Step-by-step explanation:

The range is the largest number minus the smallest number

The largest number is 1 1/4 and the smallest number is 5/8

1 1/4 - 5/8

Getting a common denominator

1 2/8 - 5/8

Borrowing from the 1 in the form of 8/8

8/8+2/8 - 5/8

10/8 - 5/8

5/8

Answer:

5/8

Step-by-step explanation:

because 1 1/4 is 5/4 then x2 which is 10/4 so now you 10/4 - 5/8 which equals 5/8 as the difference.

Answer:

Step-by-step explanation:

First, you should put the axis of symetry as 5, -7 because f(x)= (x-h)^2+k and h is 5 and k is -7. the axis of symetry is x=5 because that is the "folding point" of the graph. Next, you would have to plug In 4 and 6 as your helping points to tell you where the other points of the function are going to be.

Plug 4 in and you get -6. plug 6 in and you get -6. plot the points (4, -6) and (6,-6).

Hope this helps!

Answer:

Ravi’s present age will be 5.

Step-by-step explanation:

From the given, Let Ravi’s present age is taken as "a" years.  

After 15 years, his age = (a+15) years.  

By the given, it is identified that the age of Ravi after 15 years is equal to the 4 times of his present age.

Given,  

[tex]a+15+4a\\4a-a+15\\3a=15\\a=15/3\\a=5[/tex]

Then, it has been found that the present age of Ravi is 5 when his age after 15 years will be 4 times of his present age.

Answer:

1/5

Step-by-step explanation:

20/100

Divide the top and bottom by 20

20/20 =1

100/20 =5

20/100 = 1/5

20/100

Divide the top and bottom by 20

20/20 =1

100/20 =5

20/100 = 1/5

Answer:

y=2

Step-by-step explanation:

53y–16= 90

53y=90+16

53y=106

y=106/53

y=2

Answer:

y = 2

Step-by-step explanation:

If one side of a triangle inscribed in a circle is a diameter of the circle, then the triangle is a right triangle and the angle opposite the diameter is the right angle.

Therefor

53y - 16 = 90

add 16 to both sides

53y = 106

Divide both sides by 53

y = 106/53

y = 2

Answer: 0.36

Answer:

x = 2[tex]\sqrt{35}[/tex]

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + b² = a² , that is

x² + 2² = 12²

x² + 4 = 144 ( subtract 4 from both sides )

x² = 140 ( take the square root of both sides )

x = [tex]\sqrt{140}[/tex] = [tex]\sqrt{4(35)}[/tex] = 2[tex]\sqrt{35}[/tex]
