4.6

1) Since 3/4x = 3.45, then we can solve it for x

3/4x = 3.45 Multiply both sides by 4 to eliminate the fraction

3x =13.80 Divide both sides by 3

x= 4.6

2) So x is equal to 4.6, and that is the answer

The age for two men is 39.5 and 42.5.

A branch of mathematics known as algebra deals with symbols and the mathematical operations performed on them. Variables are the name given to these symbols because they lack set values. We frequently observe constant change in specific variables in our day-to-day situations. But the need to depict these shifting values is ongoing. These values are frequently represented in algebra by symbols such as x, y, z, p, or q, and these symbols are known as variables.

Given:

Average of 6 men = 35

Average of 4 men  = 32

So, Total age of 6 men

=6x35

=210 years

and, Total age of 4 men

=32  x 4

=128 years

Then, the remaining age for 2 people

= 210 - 128

=82 years

Let the age for two be x and y

then , x+ y=82

and x-y=3

On solving

2x =85

x=42.5 years

and y=39.5 years

Hence, the age for two men is 39.5 and 42.5.

The most appropriate choice for speed will be given by-

Speed of the flying carpet is 15.2 mph

What is speed?

The distance travelled by the body per unit time is called speed of the body.

If d is the distance travelled by the body and t is the time taken, then

speed = [tex]\frac{d}{t}[/tex]

Speed is a scalar quantity as the direction is not taken into account.

Here,

Let the speed of the flying carpet be [tex]x[/tex] miles

A flying carpet flies 2.4 miles with the wind

Time taken flying with the wind = [tex]\frac{2.4}{x +4}[/tex]

The flying carpet flies 1.4 miles against the wind

Time taken flying against the wind = [tex]\frac{1.4}{x - 4}[/tex]

By the problem,

                         [tex]\frac{2.4}{x +4} = \frac{1.4}{x-4}[/tex]  

                         [tex]2.4(x - 4) = 1.4(x + 4)\\2.4 x - 9.6 = 1.4 x + 5.6\\2.4 x - 1.4 x = 9.6 + 5.6\\[/tex]

The probability that a randomly selected person in the country enjoys cooking or shopping or both will be;

⇒ P (C ∪ S) = 0.76

What is mean by Probability?

The term probability refers to the likelihood of an event occurring.

Given that;

48% of people in a certain country like to cook.

And, 54% of people in the country like to shop, while 26% enjoy both activities.

Now,

Probability to like the cook P (C) = 48%

Probability to like the shop P (S) = 54%

Probability to like the both activity P (C∩S) = 26%

So, Probability to like the both activity P (C ∪ S) is calculated as;

P (C ∪ S) = P (C) + P (S) - P (C ∩ S)

P (C ∪ S) = 48% + 54% - 26%

P (C ∪ S) = 102% - 26%

P (C ∪ S) = 76%

P (C ∪ S) = 0.76

Thus, The probability that a randomly selected person in the country enjoys cooking or shopping or both will be;

⇒ P (C ∪ S) = 0.76

The system of linear equations has one and only one solution.

x = 3 and y = 2.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

We have,

x - 3y = -3 _____(1)

4x + 3y = 18 ______(2)

We will solve the equation to check its solutions.

x - 3y = -3 can be written as:

x = -3 + 3y ____(3)

Putting in (2) we get,

4(-3 + 3y) + 3y = 18

-12 + 12y + 3y = 18

15y = 18 +12

15y = 30

y = 2

Putting in (3)

x = -3 + 3 x 2 = -3 + 6 = 3

x = 3

We see that,

x = 3 and y = 2

Putting in the equation it is satisfied.

x - 3y = -3

3 - 3 x 2 = -3

3 - 6 = -3

-3 = -3

4x + 3y = 18

4x3 + 3x2 = 18

12 + 6 = 18

18 = 18

Thus,

The system of linear equations has one and only one solution.

x = 3 and y = 2.

Distance is the total movement of an object without any regard to direction

Given data

vertex 1 is at ( -4, - 1)

vertex 2 is at ( - 4, 5)

vertex 3 is at (2,5)

vertex 4 is at ( 2, -1 )

Lindseys jogs along the edge of the park in order from vertex 1 to the vertex 2 , vertex 2 to vertex 3 and vertex 3 to vertex 4 and then back to vertex 1. One unit in the coordinate grid is 20 yards.

Let us calculate distance vertex 1 and vertex 2of (-4,-1) and (-4,5)

x₁=-4,x₂=-4, y₂=5, y₁=-1

Distance=√(x₂-x₁)²+(y₂-y₁)²

Substitute the values x₁=-4,x₂=-4, y₂=5, y₁=-1 in distance formula

=√(-4+4)²+(5-(-1))²

=√6²

=6

Since 1 one unit on the coordinate gride equal 20 yd.

so 6×20=120 yards.

Now for four vertices we get 4×120=480 yards.

Given the sequence:

C. 3, 12, 27, 48, 75

First, we need to calculate the difference between terms:

12-3 = 9 27-12 = 15 48-27 = 21 75 - 28 = 27

Arithmetic relationship: 9, 15 , 21, 27

To obtain the sequence we use the following formula:

Now, we need to calculate the appropriate difference between terms:

15-9 = 6 21-25 = 6 27 - 21 = 6

So the constant difference is 6 and the nth term will be:

nth = 6n + 3

The first error Rafael made was that he made six arcs instead of taking the perpendicular bisector of the diameter and then making 4 arcs.

A square is constructed first by taking the perpendicular bisector of the diameter and making the four arcs and then joining them to make the square.

Observe the given graph carefully.

In a circle graph, the circle is divided into different sectors, each characterized by its central angle.

The complete circle measures 360 degrees. So the complete distribution (100% data) corresponds to 360 degrees.

In the given problem, we are concerned with the budget,

(a)

Consider the following,

So, one-fourth of the budget will correspond to the department which covers the 90-degree sector of the circle graph.

As observed from the graph, the most suitable department under this criteria is the Engineering Department.

Thus, Engineering Department gets approximately one-fourth of the annual budget.

(b)

Consider that the departments Engineering and support combiningly cover a little more than one-third of the area of complete circle.

Consider the following,

Note that the area covered by the department is a little more than one-third, so the corresponding percentage value must also be a little more than 33.33%.

From the available options, 40% is the value available next to 33.33%, so this should be the most suitable choice.

Thus, it can be concluded that approximately 40% of the annual budget goes to the departments Engineering and Support combined.

Therefore, option (b) is the correct choice.
