Answer:
![AB=12\sqrt{3}\ cm](https://tex.z-dn.net/?f=AB%3D12%5Csqrt%7B3%7D%5C%20cm)
Step-by-step explanation:
If AB is tangent to the circle, then angle ABO is right angle and triangle AOB is special
triangle. In this triangle, the leg that is opposite to the angle of 30° is half of the hypotenuse. Thus,
![AO=2BO=2\cdot 12=24\ cm.](https://tex.z-dn.net/?f=AO%3D2BO%3D2%5Ccdot%2012%3D24%5C%20cm.)
By the Pythagorean theorem,
![AB^2=AO^2-BO^2,\\ \\AB^2=24^2-12^2,\\ \\AB^2=576-144=432,\\ \\AB=12\sqrt{3}\ cm.](https://tex.z-dn.net/?f=AB%5E2%3DAO%5E2-BO%5E2%2C%5C%5C%20%5C%5CAB%5E2%3D24%5E2-12%5E2%2C%5C%5C%20%5C%5CAB%5E2%3D576-144%3D432%2C%5C%5C%20%5C%5CAB%3D12%5Csqrt%7B3%7D%5C%20cm.)
Answer:
they all as a group will be doing 1/3 of the work. There are 4 robots.
how much will each individual robot be doing from the total work?
well, how many times does 4 go into 1/3?
Step-by-step explanation:
Answer:
infinite solutions
Step-by-step explanation:
Given
3(8m + 5) = 4(6m + 7) - 13 ← distribute parenthesis on both sides
24m + 15 = 24m + 28 - 13 , that is
24m + 15 = 24m + 15
Since both sides are equal then any real value of x makes the equation true.
Thus there are an infinite number of solutions
