Answer:
70°
Step-by-step explanation:
The tangent- chord angle is one half the measure of the intercepted arc.
intercepted arc = 360° - 220° = 140°, thus
inscribed angle = 0.5 × 140° = 70°

Answer:
10 minutes
Step-by-step explanation:
Adam- 3 mph = 20 minutes a mile
Amy- 12 mph = 5 minutes a mile
Adam left 30 minutes prior to Amy so he is a mile and a half ahead before amy even starts.
30 minutes = 1.5 miles (Adam)
7.5 minutes = 1.5 miles (Amy)
but with this being said you have to continue to add time and miles to Adam because he's now gone an extra 7.5 minutes too.
45 minutes = 2.25 miles
15 minues = 3 miles
no youre too far and Amy is now further so we have to go back some
40 minutes = 2 miles
10 minutes = 2 miles
With all this being said Amy only needs to ride her bike for 10 minutes before she catches back up to Adam
Answer:
100 hours
Step-by-step explanation:
Law firm A = 350x + 22,000,
Law firm B = 410x+16,000
Where,
x = number of hours of legal assistance
What number of hours of legal assistance makes the equation 350x+22,000 = 410x+16,000 true?
Equate the legal fees of the two law firms
350x + 22,000 = 410x + 16,000
Collect like terms
350x - 410x = 16,000 - 22,000
-60x = -6,000
Divide both sides by -60
x = -6,000 / -60
= 100
x = 100 hours
The number of hours of legal assistance makes the equation true is 100 hours
