Answer:

x = 8

Step-by-step explanation:

                                                             √3                  4√3

Note that cos 30 degrees (which is ---------) equals ---------

Answer:

39 pi cubic inches

Step-by-step explanation:

The volume of a cone is (1/3)(area of the base)(height).

[tex]V=\frac{1}{3}Bh[/tex]

Find the area of the circular base.  The circumference of a circle is [tex]C=2\pi r[/tex], so

[tex]2\pi r = 6\pi\\\\r=3[/tex]

Now that you know the radius of the circular base, you can find its area:

[tex]A=\pi r^2 = \pi(3^2)=9\pi[/tex]

The height of the cone is 13.  Time to use the volume formula.

[tex]V=\frac{1}{3}Bh\\\\V=\frac{1}{3}(9\pi)(13)\\\\V=39\pi[/tex]

Answer:

Area of trapezoid = 21 cm²

Step-by-step explanation:

Given:

Length of rectangular shape = 4 cm

Width of rectangular shape = 3 cm

Base of triangle = 3 cm

Number of triangle = 3 cm

Find:

Area of trapezoid

Computation:

Area of trapezoid = Area of middle rectangle + Number of triangle[Area of triangle]

Area of trapezoid = [l x b] + 2[(1/2)(b)(h)]

Area of trapezoid = [4 x 3] + 2[(1/2)(3)(3)]

Area of trapezoid = 12 + 9

Area of trapezoid = 21 cm²

to find how many seats are in each row you have to divide the nber of students by the rows 325 by 25 is 13 seats per row

Answer:

The expected value is $0.1125

Step-by-step explanation:

The number of packages worth $0.70 in the grab bag = 20

The number of packages worth $0.60 in the grab bag = 15

The number of packages worth 30 cents in the grab bag = 5

The amount paid to pick one package = 50 cents

The number of packages in the bag, n = 20 + 15 + 5 = 40

The total value of the packages in the grab bag, 'V', is given as follows;

V = 20 × $0.70 + 15 × $0.60 + 5 × $0.30 =  $24.5

The average value of the packages in the bag, A = V/n

∴ A = $24.5/40 = 0.6125

The expected value is the value of the investment, at a point in time, the expected value E(X) is found by finding the sum of the of the calculations of the possible outcomes as follows

Whereby a $0.70 package is picked up, we have;

E(X)₁ = ($0.70 - $0.50) × 20/40 = $0.10

Whereby a $0.60 package is selected, we have;

E(X)₂ = ($0.60 - $0.50) × 15/40 = $0.0375

Whereby a $0.30 package is selected, we have;

E(X)₃ = ($0.30 - $0.50) × 5/40 = $(0.025)

Therefore, the expected value, E(X), is found as follows;

E(X) = E(X)₁ + E(X)₂ + E(X)₃

E(X) = 0.1 + 0.0375 - 0.025 = $0.1125

The expected value, E(X) = $0.1125

Answer:

54

Step-by-step explanation:

3*6*3=54

The solution is Option G.

The number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt is given by combination C = 54 ways

The number of ways of selecting r objects from n unlike objects is:

ⁿCₓ = n! / ( ( n - x )! x! )

where

n = total number of objects

x = number of choosing objects from the set

Given data ,

Let the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt be C

Now , the equation will be

The total number of shoes = 3 pairs

The total number of pants = 3 pairs

The total number of shirts = 6 shirts

And , the number of ways of choosing exactly 1 pair of shoes, 1 pair of pants, and 1 shirt  is calculated by Combination , where

The number of ways of selecting 1 pair of shoes = ³C₁

The number of ways of selecting 1 pair of pants = ³C₁

The number of ways of selecting 1 shirt = ⁶C₁

So , the total number of ways = ³C₁ x ³C₁ x ⁶C₁

On simplifying the equation , we get

The total number of ways C = 3 x 3 x 6

The total number of ways C = 54 ways

Hence , the combination is C = 54 ways

Answer:

339 cm²

Step-by-step explanation:

Using the relation for the surface area of a cylinder :

A = 2πrh

r = Radius = diameter / 2 = 4.5 / 2 = 2.25 cm

Height, h = 24 cm

A = 2 * 22/7 * 2.25 * 24

A = 339.29200 cm²

Surface Area =339 cm²

About 339cm³ of cardboard will be needed for the inner tube.

To make inner tube card board needed is 339 cm² of the material.

The surface area of a solid object is a measure of the total area that the surface of the object occupies.

Here, diameter = 4.5 cm

then, radius = 4.5/2 = 2.25 cm

          height = 24 cm

Surface area = 2πrh

                       = 2 X 3.14 X 2.25 X 24

                       = 339.12 cm²

Thus, to make inner tube card board needed is 339 cm² of the material.

Answer:

A

Step-by-step explanation:

Each student spend 0.625 hours to wash all the cars.

What is unity method?

The unitary method is a strategy for problem-solving that involves first determining the value of a single unit, then multiplying that value to determine the required value.

All the cars are washed by 1 student in 10 hours.

So, the time taken by 4 students to wash all the cars will be 10/4=2.5 hours.

This includes that 4 students wash all the cars in 2.5 hours.

So, the time invested by each student to wash cars is 2.5/4=0.625.

Therefore, each student spend 0.625 hours.

Disclaimer:

It takes one student 10 hours to wash all the cars at a car wash. If 4 students wash all the cars, how many hours will each person spend washing cars? (assume that all students wash cars at the same rate.)

Answer:

5cm

Step-by-step explanation:

Given data

Length= 3cm

Width= 4cm

Applying Pythagoras theorem

z^2= x^2+y^2

z^2= 3^2+ 4^2

z^2= 9+16

z^2= 25

square root both sides

z= √25

z= 5cm

Hence the diagonal is  5cm

Answer: R = Y

Step-by-step explanation: I'm going to assume that this is your problem:

If r = 5z and 15z = 3y, then r = ?

r = 5z

Multiply both sides of this equation by 3:

3r = 15z

Now, we know that

3r = 15z and that 15z = 3y

By the transitive property of equality, we can conclude that

3r = 3y

Dividing both sides by 3 yields this:

Answer:

$24

no, it is 48% off normal price

Step-by-step explanation:

clearance price = normal price - value of the 40% discount

value of the 40% discount = 0.4 x $50 = $20

Price = $50 - $20 = $30

final price = clearance price - value of 20% coupon

value of 20% coupon = 0.2 x $30 = $6

final price = $30 = $6 = $24

total value off normal price = $24 /$50 x 100 = 48%

Answer:

3 adult tickets and 5 children tickets.

Step-by-step explanation:

Make a chart:

1 adult + 7 children = 1(5)+7(3) = 26

2 adults + 6 children = 2(5)+6(3) = 28

3 adults + 5 children = 3(5)+5(3) = 30

4 adults + 4 children = 4(5)+4(3) = 32

5 adults + 3 children = 5(5)+3(3) = 34

6 adults + 2 children = 6(5)+2(3) = 36

7 adults + 1 child = 7(5)+1(3) = 38

The answer in bold is the only one that leads to $30, therefore he bought 3 adult tickets and 5 children tickets.

Therefore , the solution to the given problem of surface area comes out to be 24 square unit.

Shape is a unit used to describe how much overall space a material's surface occupies. A three-dimensional shape surface area is equal to the sum of its surroundings. The overall surface coverage of a multi shape is referred to as surface area. The volume of water of a cube featuring five rectangular faces can be calculated by adding up each face's specific area. As an alternative, you can identify the box's measurements using the formula below: Surface (SA) is equal to two times two times two.
