Find the area of a cross section parallel to the base of a cylinder with a radius of 2.5 cm and a height of 12 cm

Answer:

m∠BPD: 120°

mBC + mAD =120°

Step-by-step explanation:

A figure which is formed by two rays or lines that shares a common endpoint is called an angle.

Given:

mBD =70°

mCA = 170°

So,

m∠BPD= 1/2( (m∠BD + m∠CA))

=1/2(170+70)

=1/2*240

=120

and,

mBC + mAD = 360 - ( 70 + 170 )

                    = 360 - 240

mBC + mAD = 120°

Answer:

x = 13

Step-by-step explanation:

The 2 angles same- side interior angles and sum to 180°

Then the equation to use to find x is

12x - 29 + 4x + 1 = 180

16x - 28 = 180 ( add 28 to both sides )

16x = 208 ( divide both sides by 16 )

x = 13

Answer:

13

Step-by-step explanation:

Angles ( 12x - 29 ) and ( 4x + 1 ) are co - interior angles.

Sum of co - interior angles are supplementary.

12x - 29 + 4x + 1 = 180

12x + 4x - 29 + 1 = 180

16x - 28 = 180

16x = 180 + 28

16x = 208

x = 208 / 16

x = 13

Step-by-step explanation:

Square both sides and you will get

3xy/(x + y) = 4

Multiplying both by (x + y), we get

3xy = 4(x + y) = 4x + 4y

Put all the terms containing y to the left side:

3xy - 4y = 4x

y(3x - 4) = 4x

or y = 4x/(3x - 4)

Answer:

x = days he reads for 4.5 hours = 1 day

y = days he reads for 3.5 hours = 6 days

Step-by-step explanation:

Let

x = days he reads for 4.5 hours

y = days he reads for 3.5 hours

x + y = 7 (1)

4.5x + 3.5y = 25.5 (2)

From (1)

x = 7 - y

Substitute x = 7 - y into (2)

4.5x + 3.5y = 25.5 (2)

4.5(7 - y) + 3.5y = 25.5

31.5 - 4.5y + 3.5y = 25.5

- 4.5y + 3.5y = 25.5 - 31.5

-y = -6

y = 6

Substitute y = 6 into (1)

x + y = 7 (1)

x + 6 = 7

x = 7 - 6

x = 1

x = days he reads for 4.5 hours = 1 day

y = days he reads for 3.5 hours = 6 days

Given:

The factors of the quadratic function g(x) are (5x-1) and (x+4).

To find:

The solutions to the equation g(x)=0.

Solution:

If the factors of the quadratic function g(x) are (5x-1) and (x+4), then the function is defined as:

[tex]g(x)=(5x-1)(x+4)[/tex]

We need to find the solutions to the equation g(x)=0. So,

[tex]g(x)=0[/tex]

[tex](5x-1)(x+4)=0[/tex]

Using zero product property, we get

[tex]5x-1=0[/tex] and [tex]x+4=0[/tex]

[tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex]

Therefore, the solutions to the equation g(x)=0 are [tex]x=\dfrac{1}{5}[/tex] and [tex]x=-4[/tex].
