Find the odds in favor of rolling two even numbers when rolling a pair of dice.
VARVARA [1.3K]

Answer:

Which of the following is the least profitable investment for a candy shop that earns $1 profit per pound of candy?
maxonik [38]
Option 1: profit per hour = 8(1) - 10 = 8 - 10 = $(-2)
Option 2: profit per hour = 16(1) - 12 = 16 - 12 = $4
Option 3: profit per hour = 10(1) - 5 = 10 - 5 = $5
Option 4: profit per hour = 14(1) - 8 = 14 - 8 = $6

Therefore option 1 is the least profitable investment.

BlackZzzverrR [31]

Answer:

D

Step-by-step explanation:

The formula for volume of cone is  V=\frac{1}{3}\pi r^2 h

Where

V is the volume

r is the radius of the circular base

h is the height of the cone

<em>In the diagram shown, we can clearly see that height is 12, radius is 9. We can simply plug them into the formula and get our exact answer (leaving pi as pi):</em>

<em>V=\frac{1}{3}\pi (9)^2(12)\\=324 \pi</em>

<em />

<em>correct answer is D</em>
