Answer: 40 mi/h
Step-by-step explanation:
it goes up 80 and over 2, so the rate of change is 80/2 = 40 mi/h
Answer: each guest gets 4.19 cm²
Step-by-step explanation:
The cake is a circle. The area which he cuts for himself is a sector with a central angle of 120 degrees. The formula for determining the area of a sector is expressed as
Area of sector = θ/360 × πr²
Where
θ represents the central angle
π is a constant whose value is 3.14
r represents the radius of the circle.
From the diagram,
r = 4cm
Therefore, area of the cake that he cut for himself is
120/360 × 3.14 × 4²
= 16.75 cm²
The total area of the cake is
3.14 × 4² = 50.24 cm²
Therefore, the rest of the cake is
50.24 - 16.75 = 33.49 cm²
The amount that each guest gets would be
33.49/8 = 4.19 cm²

Answer:
D. (2x + 35)° = 47°
Step-by-step explanation:
If it is true the angle UOW and angle XOV are vertical angles, they must be congruent and congruent angles have the same angles. This means that in order for UOW and XOV to be vertical angles they must share the same angle.
Give you: (2x + 35)° = 47°
