Answer:

1/2(x + y)

Step-by-step explanation:

The sum of x and y is x + y

1/2 the sum of x + y is 1/2(x + y)

1/2 x^3

This is subtracted from y

y - 1/2 x^3

Answer:

B. 314 cm³

Step-by-step explanation:

We are given that,

Height of the cone = 12 cm

Radius of the cone = 5 cm

Since, we need to fill the cone with the cement. So, we will find the volume of the cone.

So, Volume of the cone = $\frac{1}{3}\pi r^{2}h$

i.e. Volume of the cone = $\frac{1}{3}\pi 5^{2}\times 12$

i.e. Volume of the cone = $\frac{1}{3}\times 3.14 \times 25\times 12$

i.e. Volume of the cone = $\frac{942}{3}$

i.e. Volume of the cone = 314 cm³

Hence, the amount of cement they can put in each cone is 314 cm³.

mel-nik [20]

Answer:

Since half of the numbers are even, 2, 4, 6

P(even) = 3/6 = 1/2

Multiple of 3 are 3 and 6:

P(multiple of 3) = 2/6 = 1/3

The numbers ≤ 4 are: 1, 2, 3, 4

P(≤4) = 4/6 = 2/3

Prime numbers are 2, 3, 5

P(prime) = 3/6 = 1/2

Numbers > 1 are 2, 3, 4, 5, 6

P(>1) = 5/6

A four, there is one option

P(4) = 1/6

Answer:

x = 5.5

Step-by-step explanation:

PM = MR

4x - 12 = -2x + 21 {add 2x to both the sides}

4x - 12 + 2x = -2x + 2x + 21

6x - 12 = 21 {Add 12 to both sides}

6x - 12 + 12 = 21 + 12

6x = 33

x = 33/6

x = 5.5
