Answer:

In the given figure:

The reflex angle \angle DOB=3y and \angle AOD = y

\angle COB = \angle AOD = y  [By vertical angle theorem]

From the given we can say that:

\angle AOC and \angle COB are supplementary angles.

Supplementary angles states that the two measure are add up to 180 degree.

⇒ \angle AOC +\angle COB = 180^{\circ}          .....[1]

then; the reflex angle DOB is:

\angle DOB = \angle AOD + \angle AOC + \angle COB

Substitute the given values we get;

3.5y=y+180^{\circ}

Subtract y from both sides we get;

2.5 y = 180^{\circ}

Divide both sides by 2.5 we get;

y = 72^{\circ}

\angle DOB = 3y = 3.5(72) =252^{\circ}

We have to find the non reflex \angle DOB

Non reflex angle DOB is;

\angle DOB = 360^{\circ}-252^{\circ} = 108^{\circ}

Therefore, the non-reflex angle DOB is 108 degree.

Bubble wrap sells in sheets, and each sheet has 1 million individual spherical bubbles, each with a diameter of 0.01 m. What is
Triss [41]

Answer: The total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.

Step-by-step explanation:

Volume of sphere :-

V=\dfrac{4}{3}\pi r^3, where r is the radius of the sphere.

Given : Diameter of the bubble = 0.01 m

Then Radius of the bubble = \dfrac{0.01}{2}=0.005\ m

Volume of each bubble:-

V=\dfrac{4}{3}(3.14) (0.005)^3

Also, Number of bubbles in each sheet = 1,000,000

Then , the total volume of air contained in the bubbles of one sheet of bubble wrap will be :-

\dfrac{4}{3}(3.14) (0.005)^3\times1,000,000=0.52333333\approx0.5\ \text{cubic meters}

Hence, the total volume of air contained in the bubbles of one sheet of bubble wrap is about 0.5 cubic meters.

What form is this equation in? y + 6 = (1/2)(x - 4)
maks197457 [2]
Y +6 =(1/2)(x+4)

y +6 = 1/2 x +2
y=1/2 x - 4

or 1/2 x -y = 4
