Answer:

76 degrees.

Step-by-step explanation:

Let as consider O is the center of the circle . So from the figure it is clear that

$\angle AOB=44^{\circ}$

$\angle COD=118^{\circ}$

By central angle theorem, central angle subtended by an arc is twice of inscribed angle of the same arc.

We know that, $\angle BAD=97^{\circ}$ and angle BOD is the central angle subtended by arc BD.

$\angle BOD=2\times \angle BAD$

$\angle BOD=2\times 97^{\circ}$

$\angle BOD=194^{\circ}$

Now,

$\angle BOD=\angle BOC+\angle COD$

$194^{\circ}=\angle BOC+118^{\circ}$

$194^{\circ}-118^{\circ}=\angle BOC$

$76^{\circ}=\angle BOC$

$m(arc(BC))=76^{\circ}$

Therefore, the measure of arc BC is 76 degrees.

An object has a potential energy of 14 J and a mass of 17 kg , how far above the ground is the object? An object moving with a s

victus00 [196]

1. Potential Energy = mgh

h = U_g / (mg) = 14 / (17 * 9.81) = 0.084 m above the ground.

2. Kinetic Energy = 1/2 mv^2

m = 2K_e / (v^2) = 2.45 kg

3. U_g = mgh = (1200)(9.81)(24) = 282528 J

4. U_g = mgh = (478)(9.81)(150) = 703377 J

5. U_g = mgh = (100)(9.81)(12.5) = 12262.5 J

6. h = U_g / (mg) = 14 / (17 * 9.81) = 0.084 m above the ground.

7. m = U_g / (gh) = 1500 / (9.81 * 35) = 4.37 kg

A printer is printing photos. For every 15 photos, the printer takes 3 minutes.

Alex17521 [72]

Answer:

3:15, 5:25, 7:35, 8:40, 10:50

Step-by-step explanation:

When I first tried this I thought it was for every one there was fifteen. I messed up then looked, realized, and changed it. For every 3 there is 15 so 15 ÷ 3 = 5 so when I saw the 5 I multiplied it by five to get 25 then continued throughout. Your first step when doing these problems again is to divide (but make sure you divide the right number) then once you find out that sweet number, multiply is by the time to get the photos, and divide by five on the photos to get the time.

Hope you got this right!
