c. 2036
Step-by-step explanation:
it seems there are some mistakes with this text.
if I understand correctly, than she runs on a circular track with a radius of 79 ft for 126 ft.
and we need to find the angle of the arc (the part-circle) she was running.
for that we need to find the ratio arc length / circle circumference, and then multiply that with 360° (you know, a full circle represents 360°, one full turn around), and that will be the arc angle.
the circle circumference is
2×pi×r = 2×pi×79 = 496.3716393... ft
the arc angle is therefore
360 × 126 / 496.3716393 = 91.38314201...°
rounded to the nearest degree : 91°

Answer:
t=10
Step-by-step explanation:
3*(t+4)-2*(2*t+3)-(-4)=0
Step by step solution :
Step 1 :
Equation at the end of step 1 :
((3 • (t + 4)) - 2 • (2t + 3)) - -4 = 0
Step 2 :
Equation at the end of step 2 :
(3 • (t + 4) - 2 • (2t + 3)) - -4 = 0
Step 3 :
Equation at the end of step 3 :
10 - t = 0
Step 4 :
Solving a Single Variable Equation :
4.1 Solve : -t+10 = 0
Subtract 10 from both sides of the equation :
-t = -10
Multiply both sides of the equation by (-1) : t = 10
