Inverse equation t=120r/r+120 R=???

Answer:

r = 120t/(120-t)

Step-by-step explanation:

Multiply by the denominator, isolate r terms, then divide by the coefficient of r.

$t=\dfrac{120r}{r+120}\qquad\text{given}\\\\t(r+120)=120r\qquad\text{multiply by $(r+120)$}\\\\120t=120r-tr\qquad\text{subtract $tr$}\\\\\dfrac{120t}{120-t}=r\qquad\text{divide by the coefficient of $r$}\\\\\boxed{r=\dfrac{120t}{120-t}}$

Arc measure - Hello! Can you please help me and if you can explain the formula that would be awesome!

Ratling [72]

9514 1404 393

Answer:

88°

Step-by-step explanation:

Angle MQP is called an "inscribed angle." Its vertex (Q) is on the circle, and its sides are chords of the circle. The ends of the sides intercept arc MP. The relationship between an inscribed angle and the intercepted arc is that <em>the measure of the arc is twice the measure of the angle</em>.

arc MP = 2×∠MQP = 2×44°

arc MP = 88°
