Answer:
∠3=80°
Step-by-step explanation:
∠5=∠2 (alternate angle)
∠5=38
so ∠2=38
∠6=62
∠3+∠6+∠2=180
∠3+62+38=180
∠3=180-100=80
Decimal = 0.001
fraction = 1/1000
The box-and-whisker plot is just a fancy way of dividing stuff into quarters.
1/4 (a quarter) of the tanks use 350-450 gallons.
1/4 use 450-500 gallons.
1/4 use 500-600 gallons.
1/4 use 600-750 gallons.
Two of those are above 500.
1/4 and 1/4 makes 2/4 or 1/2.
The cost of the visit to the dentist can be expressed as the cost equals 100x+50.
The initial cost of the appointment would be $50; no matter how many cavities one has, they would still have to pay $50.
The cost of each cavity is represented as 100x, because each cavity costs $100. x represents the number of cavities, as we do not know how many cavities there are.
