Good luck on your assignment

The required volume of the given cylinder is 2260.8  cubic centimeters.

The volume of a cylinder is equal to the product of the area of the circular base and the height of a cylinder. The volume of a cylinder is defined as the space occupied by the cylinder as the volume of any three-dimensional shape is the space occupied by it

V = πr²h

where 'r' is the radius of the base (circle) of the cylinder

'h' is the height of the cylinder

As per the given question, we have data as:

Radius(r) = 6 cm

Height(h) = 20 cm

Volume of cylinder = πr²h

Volume of cylinder = 3.14 × (6)² × 20

Volume of cylinder = 3.14 × 36 × 20

Volume of cylinder = 2260.8 cm³

Thus, the required volume of the given cylinder is 2260.8  cubic centimeters.

Step-by-step explanation:

volume of pyramid is given by 1/3(Area of base* height)

Given base of pyramid is square with length of each side s

area of square is given by [tex]side^2[/tex]

Thus, area of base of pyramid = [tex]s^2[/tex]

Height of pyramid = 2/3  of  side of base of pyramid = 2/3* s = 2s/3

Therefore volume of pyramid = 1/3(area of base of pyramid *Height of pyramid)

                                            = [tex]1/3(s^2*2s/3)[/tex]

                                             = [tex]2/9*s^3[/tex]

Thus, correct choice is option d [tex]v=2/9*s^3[/tex]

The arc length covered by the central angle equal to 72° is 12.56°

Arc length is the distance between two points along a section of a curve.

Given that, a circle with radius 10 units and a central angle equals 72°, we need to find the arc length covered by the central angle = 72°

We know that,

Arc length = 2π × radius × (θ / 360°), where θ is the central angle

Arc length = 2 × 3.14 × 10 × 72°/360°

= 12.56°

Hence, the arc length covered by the central angle equal 72° is 12.56°

Answer:

The correct option is C.

C) -x + 2

Step-by-step explanation:

In mathematics, the term which is being divided is called a dividend. The term by which the dividend is getting divided is called a divisor. The quotient is the term we get after dividing the dividend by a divisor.

Here in this case, the dividend is written.

-x²    x    x

which in the equation form is written as

-x² + x + x

add the x terms to simplify

-x² + 2x

The divisor is given as x, divide the equation by x:

(-x² + 2x)/x

(-x²/x) + (2x/x)

-x+2

Which is the quotient.

Answer: y = 4/3x-9

Step-by-step explanation:

We just need to find the y-intercept, b. Recall that y-intercept form is y=mx+b. Plug in what we have. y=-4, m= 4/3, x=-9.

4= 4/3(9)+b

4=13+b

-9=b

now rewrite the equation with b now. y= 4/3x-9

Number of red ball = 26

Find:

Number of days purchase all possible ticket

Computation:

Number of days purchase all possible ticket = ⁶⁹C₅ × ²⁶C₁

Number of days purchase all possible ticket = [69! / (5!64!)]26

Number of days purchase all possible ticket = [69 × 68 × 67 × 66 × 65 × 26] / [5 × 4 × 3 × 2 × 1]

Answer:

Step-by-step explanation:

→Before you use the formula to find the area of the isosceles triangle, you must find the height, and to do this, you can use the Pythagorean Theorem:

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

→We are given the hypotenuse, "c," as 13, and the leg is 5 (we split the base of 10 in half).

[tex]5^2+b^2=13^2[/tex]

[tex]25+b^2=169[/tex]

→Subtract 25 from both sides:

[tex]b^2=144[/tex]

→To get "b," by itself, take the square root of both sides:

[tex]\sqrt{b^2} =\sqrt{144}[/tex]

[tex]b = 12[/tex]

→Formula for area:

A = [tex]\frac{bh}{2}[/tex]

A = [tex]\frac{(10)(12)}{2}[/tex]

A = 60

The area of the isosceles triangle is 60 square units.

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the triangle in a two-dimensional plane is called the area of the triangle.

The area is calculated by having the height of the triangle and the base of the triangle.

The height is calculated by using the Pythagorean theorem.

H² = P² + B²

13² = P² + 5²

P² = 169 - 25 = 144

P = √144 = 12 units

The perpendicular is the height of the triangle.

The area is calculated as:-

A = ( 1 / 2 ) x B x H

A = ( 1 / 2 ) x 10 x 12

A = 60 square units.

y = -3 (x + 6)   when graphed with the given equation, will form a system that has no solution

Step-by-step explanation:

Given line equation: [tex]y=-3x+6[/tex]

We are supposed to find Which equation, when graphed with the given equation, will form a system that has no solution.

We know that a system of two linear equations has no solution if and only if the two equations have the same slope, but not the same y-intercept.

General equation of line = [tex]y=mx+c[/tex]

A)y = 3 x + 6

So, Slope = 3

B)y = -3 (x + 6)

y=-3x-18

So, slope=-3

C)y=-3(x-2)

y=-3x+6

So, Slope = -3

D)y=3(x-2)

Slope =3

So, B has the same slope but different intercept

So,y = -3 (x + 6)   when graphed with the given equation, will form a system that has no solution

Answer:

B) y= -3(x+6)

Marked Price(MP)=$45.00

Discount percent=30%

Now,

Discount amount=Discount % of MP

= 30% of 45

=$13.5

Again,

Sale price(SP)=MP-Discount

y = 14

Step-by-step explanation:

The sum of the angles in a triangle add to 180 degrees

50 + 2x+ 5y + 10 = 180

We know that 2x = 50 since they are the base angles of sides that have the same length, they must be the same

50 + 50 + 5y+10 =180

Combine like terms

110 + 5y =180

Subtract 110 from each side

110+5y-110 = 180-110

5y = 70

Divide each side by 5

5y/5 =70/5

y = 14
