Remi has two cone-shaped containers with the same diameter. He will place the smaller container inside the larger one. Before he

does this, he wants to fill the larger container with water so that it will be completely full but won’t spill when he places the smaller container inside. The diameter of both containers is 12 cm. The height of the smaller container is 6 cm, and the height of the larger container is 18 cm. What volume of water must Remi put in the large container? Use 3.14 to approximate pi and express your final answer in hundredths. cm3 Diagram showing shorter cone inside taller cone. Both cones share same base, which is fourteen centimeters across. A perpendicular dotted line from middle of base to the point of the shorter cone is labeled three centimeters. A perpendicular dotted line from edge of base to a point level with the point of the taller cone is labeled seventeen centimeters.

Given:
Big cone     : diameter = 12 cm ; height = 18 cm ; base = 14 cm
Small cone: diameter = 12 cm ; height = 6 cm ; base = 14 cm

Volume of a cone-shaped container = π r² h/3
Big cone:
V = 3.14 * (6cm)² * 18cm/3
V = 3.14 * 36cm² * 6cm
<span>V = 678.24 cm³

</span>Small cone:
V = 3.14 * (6cm)² * 6cm/3
V = 3.14 * 36cm² * 2cm
<span>V = 226.08 cm³

</span>Big cone - small cone = volume of water
678.24 cm³ - 226.08 cm³ = 452.16 cm³

From the ques ton we are told that

Total amount N=15

Choices within 10 pop, 25 reggae, 10 blues

Generally for equal amount in her play list she's mathematically Going to have 5 of each kind  Pop,Reggae,Blues

Therefore

Let the amount of differnt playlist be given as P

P=^1^0C_5*^2^5C_5*^1^0C_5*15!

P=252*53130*252*1307674368000

P=4.41205084*10^2^1

Therefore P=4.41205084*10^2^1  different playlists are possible

natta225 [31]

Answer:

12/7

Step-by-step explanation:

To set up a ratio of "thing 1" to "thing 2", build a fraction with "thing 1" on top (numerator) and "thing 2" on the bottom (denominator).

The ratio of in-state students to out-of-state students is \frac{108}{63} and this can be simplified ("reduced") by dividing both numbers by 9 to get the fraction 12/7.

Solve the question: 3(.5y-6)=12​
makvit [3.9K]

Answer:

y = 20.

Step-by-step explanation:

Distribute:

3(0.5y)-3(6)=12

1.5y-18=12

Add 18 to both sides:

1.5y-18+18=12+18

1.5y=30

Solve for y:

\frac{1.5y}{1.5}=\frac{30}{1.5}

y=20
