Answer:
b=70 degrees
Step-by-step explanation:
a= 8x+6. b= 4x+38
a=b alternate exterior
combine like terms
8x+6=4x+38
Subtract 4x from both sides and 6
4x=32
Divide by 4
x=8
Plug in= 8 for B equation
b= 4(8)+38
b=70 degrees
It has to be the lowest number which is .01.
Answer:
300 calories
Explanation:
- perimeter of circle : 2 π r
Here radius:
perimeter of track = 2 π r = 2 (3.14) (75) = 471 ft
total laps ran:
So calories burnt:
A(100-62)/100=17100 multiply both sides by 100
a(100-62)=1710000 combine like terms on left side
38a=1710000 divide both sides by 38
a=45000
So the arena has a total of 45000 seats.
