angles a and b are supplementary because they form a straight line
The relation is not a function because the x repeats twice.
Answer:
Step-by-step explanation:
<u>Amount paid for food booth</u>
- 15*$100 + 15*d*$5 = 75d + $1500
<u>Amount paid for game booth</u>
- 20*$50 + 20*d*$7 = 140d + $1000
<u>Total amount paid</u>
- 75d + $1500 + 140d + $1000 = 215d + $2500
Answer:
D
Step-by-step explanation:
We require to calculate the volume (V) of the cone and sphere.
The volume of a cone is calculated as
V =
πr²h ( r is the radius and h the height )
Here diameter = 5, hence r = 5 ÷ 2 = 2.5, thus
V =
π × 2.5² × 8 ≈ 52.36 cm³
The volume of a sphere is calculated as
V =
πr³ ( r is the radius )
Here diameter = 5, hence r = 5 ÷ 2 = 2.5, thus
V=
π × 2.5³ ≈ 65.45 cm³
Since volume of the sphere is greater than the volume of the cone
Thus when the ice cream melts it will overflow → D
