An island has three villages and the total number of males is 75. The first village has 20 males and 25 females. The second village has 50 people of whom 30 are males. The third village has 30 females.

Answers

Answer 1

There are 25 males in village 3

The number of males in the third village?

The given parameters are:

Total males = 75

                 Male     Female   Total

Village 1   20              25

Village 2  30                            50

Village 3                     30

Total         75

The number of male in village 3 is calculated using:

Male = Total Male - Male in villages 1 and 2

So, we have:

Male = 75- (20 + 30)

Evaluate

Male = 25

Hence, there are 25 males in village 3

Answers

Answer: [tex]60cm^2[/tex]

Step-by-step explanation:

Looking at the figure, you can see that the length is 5cm + 3cm = 8cm and the width is 2cm + 5cm + 2cm = 9cm.

The formula for area is length x width, therefore you do 8x9 which is 72.

Next, we solve for the two "dips" in the rectangle. We can do that by subtracting the area of the "mini-rectangles" from the whole figure:

72-2(2x3) = 60

Thus, 60cm^2 is your answer.

The solutions of the equation given as |2/3x + 2| − 8 = 0 are x = 9 and x = -15

What is equation?

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal.

here, we have,

to determine the solutions of the equation:

The equation is given as:

|2/3x + 2| − 8 = 0

Start by adding 8 to both sides of the equation.

So, we have

|2/3x + 2| = 8

Next, we remove the absolute value expression

So, we have;

2/3x + 2 = 8 and 2/3x + 2 = -8

Subtract 2 from both sides of the equation

2/3x = 6 and 2/3x = -10

Multiply the equation by 3/2

x = 9 and x = -15

Hence, the solutions of the equation given as |2/3x + 2| − 8 = 0 are x = 9 and x = -15

Flo sets a goal of walking 12,000 total steps per day. flo's normal routine involves walking 6,000 steps per day. if flo walks 100 steps per minute, how many extra minutes should she walk per day beyond her normal routine?

Answers

Flo should walk 60 extra minutes of time per day to accomplish her goal of walking 12,000 total steps per day.

Calculating the Time for Which Flo Walks Each Day

Flo walks 6,000 steps per day.

She walks 100 steps per minute.

Time taken by Flo to cover 6,000 steps = [tex]\frac{6000}{100}[/tex] minutes

Time taken by Flo to cover 6,000 steps, m₁ = 60 minutes

Hence, Flo walks for 60 minutes or 1 hour per day.

Calculating the Extra Hours of Walking

Steps to be covered by Flo each day = 12,000

Time required to walk 12,000 steps per day, m₂ = [tex]\frac{12000}{100}[/tex] minutes

⇒ m₂ = 120 minutes

Extra hours of walk per day = (m₂-m₁) minutes

= (120 - 60) minutes

= 60 minutes

Thus, Flow should walk 1 hour extra to be able to accomplish a goal of walking 12,00 steps per day.

Answers

The area of the triangle, trapezoid, rectangle and total area are 7. 5 ft², 10. 5 ft², 0.8 ft² and 18. 8 ft² respectively.

How to determine the area

1. Area of a triangle = 1/2 base × height

Area = 1/2 × 5 × 3

Area = 1/2 × 15

Area = 7. 5 ft²

2. Area of trapezoid = [tex]\frac{a + b}{2} h[/tex]

a = 4ft

b = 0. 2ft

h = 5ft

Area = [tex]\frac{4 + 0.2}{2}* 5[/tex]

Area = [tex]\frac{4.2}{2} * 5[/tex]

Area = 2.1 × 5

Area = 10. 5 ft²

3. Area of rectangle = length × width

Area of rectangle = 0. 2 × 4

Area of rectangle = 0. 8 ft²

4. Total area of tree = area of triangle + area of trapezoid + area of rectangle

Total area of tree = 7. 5 + 10. 5 + 0. 8

Total area of tree = 18. 8 ft²

Thus, the area of the triangle, trapezoid, rectangle and total area are 7. 5 ft², 10. 5 ft², 0.8 ft² and 18. 8 ft² respectively.

A high school senior applies for admission to college A and to college B.

What is the probability that he will be rejected to at least one of the colleges

Answers

The probability that he will be rejected to at least one of the colleges is 0.51.

Given probability that he will admit in A is 0.7, probability that he will not be admit in B is 0.5, probability that atleast one of his applications got rejected is 0.6.

We have to find the probability that he will be rejected to at least one of the colleges.

Probability that he will admit in A =0.7

Probability that he will not admit in A=1-0.7=0.3

Probability that he will not admit in B =0.5

Probability that he will admit in B=1-0.5=0.5

Probability  that he will be rejected to at least one of the colleges=probability that he will admit in A* probability that he will not admit in B+ probability that he will admit in B* probability that he will not admit in A+ probability that he will not admit in A* probability that he will not admit in B

=0.7*0.5+0.5*0.3+0.5*0.3

The correct options, in order, are:

[tex]f(n) = 2*(6)^{n - 1}[/tex]

[tex]f(n) = 2*(4)^{n - 1}[/tex]

How to match the equations and the tables?

The first table is:

n   f(n)

1     3

2    6

3    12

Notice that when n = 1, all the exponents are 0, then the initial value is 3.

When n = 2, all the exponents are 1. Then we need to find the exponential equation with a base equal to 2.

So the exponential equation is:

[tex]f(n) = 3*(2)^{n-1}[/tex]

The second table is:

n   f(n)

1     2

2    12

3    72

By looking at the first pair, we conclude that the initial value is 2, and by looking at the second pair, we conclude that:

2*b = 12

b = 12/2 = 6

The base is 6.

So the exponential equation now is:

[tex]f(n) = 2*(6)^{n - 1}[/tex]

The last table is:

n   f(n)

1     2

2    8

3    32

Here we again have an initial value of 2, and the base is:

2*b = 8

b = 8/2 = 4

Then the correct option now is:

[tex]f(n) = 2*(4)^{n - 1}[/tex]
