Answer:
2.5
Step-by-step explanation:
56(t+1/2)=70 t
56T + 28= 70T
28=70T-56T
28=14
2=T
s=T+ 1/2
S=2+ 1/2
S=2.5 hours
Answer:
Area: 96 x pi
Perimeter: 8 x pi
Step-by-step explanation:
Area: the shaded part is 1/3 of the circle and is 120 degrees of the 360 degrees of the circle
use the area formula: r^2 x pi x 120/360
plug in r=12 and you should get 96 pi
Perimeter: the formula for circumference is 2 x pi x r x 120/360
plug in r=12 and you should get 8 x pi
Answer:
None
Step-by-step explanation:
Simply, the absence of s^-1 shows the answer as none
