Answer:

Option B

Step-by-step explanation:

Given:

4 - 3i

Conjugate of the given number is:

4 + 3i

Divide the given number by its conjugate:

(4 - 3i) / (4 + 3i) = (4 - 3i)(4 - 3i) / (4 + 3i)(4 - 3i) =(16 + 9i² - 24i) / (16 - 9i²) = (16 - 9 - 24i) / (16 + 9) = (7 - 24i) / 25 = 7/25 - 24i/25

Simplify the ratio-

2kg : 3kg : 1.5 kg

Answers

Answer:

1.33kg : 2kg : 1kg

Step-by-step explanation:

2kg : 3kg : 1.5 kg

Given data

We have the ratio

2kg : 3kg : 1.5 kg

Let us reduce the ratio further

2/1.5: 3/1.5 : 1.5/1.5

1.33kg : 2kg : 1kg

Hence the simplified ratio is 1.33kg : 2kg : 1kg

I need some help finding the volume of a sphere with a diameter of 18.6cm. The website says the answer I got from my calculator was wrong! Help would be greatly appreciated!

Answers

Answer:

V = 3,367.6 cm³

Step-by-step explanation:

Diameter of sphere (D) = 18.6 cm

radius (r) = ½(18.6) = 9.3

π = 3.14

Formula for volume of a sphere = ⁴/3πr³

Plug in the values

V = ⁴/3 × 3.14 × 9.3³

V = ⁴/3 × 3.14 × 804.357

V = (4*3.14*804.357)/3

V = 3,367.57463

V = 3,367.6 cm³ (nearest tenth)

question. Here are the results:

What is the expected count for the cell corresponding to east coast subscibers who
responded "yes"?
You may round your answer to the nearest hundredth.

Answers

Answer:

19.2

Step-by-step explanation:

khan

The expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

We need to first calculate the expected frequencies for each cell under the assumption that the null hypothesis of homogeneity is true.

The null hypothesis of homogeneity assumes that the proportion of internet subscribers satisfied with their internet speeds is the same on both the east and west coasts of the United States.

To calculate the expected frequencies, we can use the formula:

Expected frequency = (row total x column total) / grand total

For the cell corresponding to east coast subscribers who responded "yes":

Expected frequency = (row total for east coast x column total for "yes") / grand total

= (80 x 48) / 200

= 19.2

Therefore, the expected count for the cell corresponding to east coast subscribers who responded "yes" is 19.2.

solve 3x by 4 - 2x+5 by 3 = 5 by 2​

Answers

Answer:

50

Step-by-step explanation:

The given equation is,

→ 3x/4 - (2x + 5)/3 = 5/2

→ 3x × 3 - 4(2x +5)/12 = 5/2

→ 9x - 8x -20/12 = 5/2

→ (x - 20)/12 = 5/2

→ x - 20 / 6 = 5

→ x - 20 = 30

→ x = 20 + 30

→ x = 50

• Hence the value of x is 50 .

Closest to the shaded area

Answers

Answer:

B) 30.9

Step-by-step explanation:

So, because the radius is 6, we know the diameter is 12, meaning we know each side is 12, so the total area of the square is 144.

To find the area of a square we should use pi(r) ^2 which is pi(6) ^2 which is 113.09. to find the area of the shaded are we would subtract these. 144- 113.09 this gets us 30.91, this is closest to B) 30.9

I believe it would 18 ounces of chips for 3 cups of flour. If you take half of 12 ounces then you get 6 ounces per cup of flour. Adding 6 ounces to the 12 would get us the total of the 18 ounces.

The formula for the area of a triangle is 1A bh2=, where b is the length of the base and his the height. Rearrange the formula to isolate h

Answers

Answer:

h = 2A/b

Step-by-step explanation:

Area of a triangle, A = 1/2bh

Where,

b = base of the triangle

h = height of the triangle

Rearrange the formula to isolate h

A = 1/2bh

Multiply both sides by 2

2 * A = 2 * 1/2bh

2A = bh

Divide both sides by b

2A / b = bh / b

2A / b = h

Therefore,

h = 2A/b

help please help help help

Answers

Answer:

area = 32

perimeter = 30

Step-by-step explanation:

Formulas:

Area of a parallelogram: A = bh

Perimeter of a parallelogram: P = 2 ( b + s )

Where h = height s = slant height and b = base length

Define:

b = 8

h = 4

s = 7

Plug in given values into formulas and calculate

A = (8)(4)

8 * 4 = 32

A = 32

P = 2 ( 8 + 7 )

8 + 7 = 15

2(15) = 30

P = 30

Answer: hello your question is Vague hence I will provide a general solution. in which you can input your values into  and get your answer.

answer = h  = 3 ( V / π r^2 )  

Step-by-step explanation:

The volume of a cone is exactly the volume of a hemisphere, given that the radius and height are the same .

The height of the water in the cone = height of the hemisphere / height of cone ( given that the water completely fills the hemisphere )

∴ h  = 3 ( V / π r^2 )

Answer:

Step-by-step explanation:

the diameter is a circle is 16in. Find it’s circumference in terms of π.

C= ________in

Answers

S O L U T I O N :

According to the question,

Diameter of circle = 16 in

We are asked to calculate it’s circumference in terms of π.

★ Circumference of circle = 2πr

___________________________________

Let us first calculate the radius of the circle.

→ Diameter = 2 × Radius

→ 16 in = 2r

→ r = 16 in ÷ 2

→ r = 8 in

___________________________________

Substituting values in the formula of circumference,

→ C = 2πr

→ C = (2 × π × 8) in

→ C = 16π in

Therefore, 16π inches is the required answer.

Ann is twice as old as mary and three times as old as donald. Together their ages total 99. How old is ann?

Answers

Answer:

54 years

Step-by-step explanation:

Given that :

Let :

Ann's age = x

Mary's age = x/2

Donald's age = x/3

x + x/2 + x/3 = 99

Take the L. C. M

(6x + 3x + 2x) / 6 = 99

11x / 6 = 99

11x = 99 * 6

11x = 594

x = 594 / 11

x = 54

Hence, Ann is 54 years
