Answer:

  • arc AB = 60°
  • arc BC = 78°
  • arc EF = 40°
  • angle AFB = 30°

Step-by-step explanation:

The relevant relations are ...

  • the measures of an arc and its central angle are the same
  • the sum of the arcs of a circle is 360°
  • the measure of an inscribed angle is half the measure of the arc it intercepts

__

Arc AB has the measure of central angle AOB, 60°.

Arc EF has double the measure of inscribed angle EAF, so is 40°.

Arc BC completes the circle, so has measure ...

  arc BC = 360° -arc FA -arc AB -arc CE -arc EF

  arc BC = 360° -140° -60° -42° -40°

  arc BC = 78°

Angle AFB is half the measure of arc AB, so is 60°/2 = 30°.

The volume of a cube is side length cubed (s^3)
So if you know the volume then take the cube root of 1/512... which is 1/8

So each side of the cube is 1/8.

There are 6 congruent sides on a cube (picture a “dice”). Do the area of each side would be (1/8)(1/8)= 1/64 then multiply that area by 6 and reduce ... you get 6/64 = 3/32 for the surface area

The profit a company earns every month depends of the amount of product sold, p, for $855 each and the amount spent in rent, uti
3241004551 [841]
Profit = (selling price x number of units) - expenses in this case, the selling price is $855, number of units is 250, and the expenses are $6,780 So, Profit = ($855 x 250) - $6,780 = $206,970 That number times 15% (decimal = 0.15) will be the salary of the CEO So, $206,970 x 0.15 = $31,045.50
