Answer: 20

Step-by-step explanation: imagine the books in 10's cuz 30/3=10 and 2 of those tens out of the group of three are nonfiction, so that makes 20 out of 30

The number of songs Kim started with are 18songs while the number of songs Eric started with are 36 songs.

Firstly, Kim = 1/2 of Eric's

Ed = 1/3 of Kim= 6 songs

Eric = 2 songs

Total songs by the whole traders is = 12 ×3 = 36songs

If Kim gave Ed, 1/3 of her songs =6 , then her whole song is 6×3 = 18songs.

But she gave out 6 to Ed so 12 songs will remain.

If 18 songs received by Kim is half of Eric songs therefore, 18×2 = 36

But half was given to Kim therefore 18 songs is remaining for Eric

Ed received 6songs from kim and gave out 2, there, 4 songs is remaining for Ed.

Therefore the number of songs Kim started with are 18songs while the number of songs Eric started with are 36 songs.

Step 1:  Convert words into an expression

Four times the quotient of 3 divide by 4

We know that we are going to be multiplying 4 by something because in the statement we have four times.  Reading further we also know that we are going to be dividing 4 from 3 which means that we will have 3/4.  Finally, we see that we multiply our 3/4 by 4 which gives us our final solution.

[tex]4 * (3 / 4)[/tex]

If we want to solve it the 4's would just cancel and we would be left with 3.

Explanation:

You would start by dividing 3 by 4. Then multiply [tex]\frac{3}{4}[/tex] and 4. The 4s would cancel out leaving you with 3.

The coin is an illustration of probability, and the probability of getting two heads and a tail is 3/8

The sample space of tossing a coin three times is:

S = {HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}

On the sample space, we have:

Two heads and a tail = 3

Sample size = 8

The required probability is then calculated using:

P = 3/8

Answer:

xy represents the diameter

Answer:

The formula for volume of a cone is area of a circle times height, divided by 3.

Therefore volume is pi times radius squared times height, divided by 3.

V = (3.14)(14)^2 (14)/3

V = (3.14) (196)(14)/3

V = (3.14) (2744)/3

V = 8616.16/3

V = 2872.05333

Answer:

r = 4/5

Step-by-step explanation:

Formula

Sum of an infinite geometric series = a / (1 - r)

Givens

Sum = 5*a

a = a

r = ?

Solution

5a = a/(1 - r)                   Divide both sides by a

5a/a = a / (a * (1 - r)       The a's on the right cancel

5 = 1 / (1 - r)                    Multiply both sides by 1 - r

5*(1 - r) = 1*(1 - r)/(1 - r)   The 1 - r s on the right cancel

5*(1 - r) = 1                     Remove the brackets.

5 - 5r = 1                        Subtract 5 from both sides

5-5 - 5r = 1 - 5               Combine

-5r = - 4                          Divide by - 5

r = 4/5  

In the circle the measure of angle QPR in radians is π/4.

What is a circle?

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the centre.

The length of the arc QR is 4π, which is 1/2 of the circumference of the circle P.

Therefore, the circumference of the circle is -

2πr = 2π(8) = 16π

The angle subtended by the arc QR at the center of the circle is therefore -

θ = arc length / radius

θ = (4π) / 8

θ = π/2

Now, consider the triangle QPR.

The angle QPR at the center of the circle is equal to twice the angle subtended by the arc QR at any point on the circumference of the circle.

Therefore -

2∠QPR = θ = π/2

Solving for ∠QPR, we get -

∠QPR = (π/2) / 2

∠QPR = π/4

Therefore, the measure QPR is π/4.

area of square = length²

c = side opposite right angle = length of square Z
