Answer:

x = 30

Step-by-step explanation:

\( \triangle JLK\sim\triangle PQR\) (given)

\( \therefore \frac{JL}{PQ}=\frac{LK}{QR} \)

(corresponding sides of similar triangles)

\( \therefore \frac{20}{x}=\frac{22}{33} \)

\( \therefore \frac{20}{x}=\frac{2}{3} \)

\( \therefore x=\frac{20\times 3}{2} \)

\( \therefore x=\frac{60}{2} \)

\( \therefore x=30 \)

Or using scale factor:

Scale factor = 33/22 = 3/2

x = 20*3/2

x = 10*3

x = 30

Answer:

x = 13

Step-by-step explanation:

2(x + 18) and (3x + 79) are a linear pair and sum to 180° , that is

2(x + 18) + 3x + 79 = 180

2x + 36 + 3x + 79 = 180

5x + 115 = 180 ( subtract 115 from both sides )

5x = 65 ( divide both sides by 5 )

x = 13

Answer:

x = 13

Step-by-step explanation:

Given angles are,

→ 3x + 79°

→ 2(x + 18)° = 2x + 36°

Now we have to,

→ Find the required value of x.

We know that,

→ Sum of all angles in a line is 180°.

Forming the equation,

→ (3x + 79°) + (2x + 36°) = 180°

Then the value of x will be,

→ (3x + 79°) + (2x + 36°) = 180°

→ 3x + 79° + 2x + 36° = 180°

→ (3x + 2x) + (79 + 36)° = 180°

→ 5x + 115° = 180°

→ 5x = 180° - 115°

→ 5x = 65

→ x = 65/5

→ [ x = 13 ]

Hence, the value of x is 13.

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

Rounded to the nearest hundredth, the value of y at \(x = 7\) is approximately \(12.78\), according to the concept of linear regression line.

To find the linear regression line for the given data, we can use statistical software or a calculator. The equation of the linear regression line is of the form \(y = mx + b\), where m represents the slope and b represents the y-intercept.

Using the provided data, the linear regression line equation is:

\(\[ y = 1.3642x + 3.2324 \]\)

To find the value of \(y\) at \(x = 7\), we substitute \(x = 7\) into the equation:

\(\[ y = 1.3642(7) + 3.2324 \]\)

Simplifying the equation, we get:

\(\[ y = 9.5494 + 3.2324 \]\[ y = 12.7818 \]\)

In conclusion, the linear regression analysis allows us to determine the relationship between the variables x and y in the given data set. By finding the equation of the linear regression line, we can estimate the value of y for any given x. In this case, the linear regression line equation is \(y = 1.3642x + 3.2324\). By substituting \(x = 7\) into the equation, we find that the estimated value of y is approximately \(12.78\). This analysis provides a useful tool for predicting and understanding the relationship between variables, allowing us to make informed decisions and interpretations based on the data.

Salinas will use 32 gallons for 480 miles

Salinas used 15.6 gallons of gas for 234 miles

Miles can be described as the distance travelled by an object or an individual

The first step is to calculate the number of miles travelled using 1 gallon

15.6= 234

1= x

cross multiply both sides

15.6x= 234

x= 234/15.6

x= 15

1 gallon will take her 15 miles

Therefore, the number of gallons required for 480 miles can be calculated as follows

1= 15

x= 480

cross multiply both sides

15x= 480

x= 480/15

x= 32

Hence Salinas will require 32 gallons for 480 miles of the journey

The required principal amount = $22.42

Amount to be earn (A)  = $80.08

Given rate of interest (r) = 4% = 0.04

And time (t) = 7 years

What is the principal amount for investment?

Principal is also the original amount of investment made in an asset, separate from any earnings or interest accrued.

Since we know the simple interest formula;

A = p(1 + rt)

Therefore, substituting the values;

80.08 =  p[1 + (0.04)(7)]

80.08 =  0.28p

P = 80.08/0.28

P = $22.42

Thus,  the required principal amount = $22.42

A = 139°

B = 139°

You can see A and B are coefficients of each other, which means they have the same angle because they are opposite each other on the straight line. just like the two 41° angles are.

The angle around a point always add up to 360°, so add the 41° angles.

41 + 41 = 82°

Then minus this by 360°.

360 - 82 = 278°

And to work out one angle, which gives you the angle for both, divide 278 by two.

278 ÷ 2 = 139°

Both A and B have an angle of 139°

Example:

To find the value of two intersecting lines, you need to know the equations of both lines. Then, you can set the equations equal to each other and solve for the variable x. This will give you the x-coordinate of the point where the lines intersect. To find the y-coordinate, you can plug the value of x into either equation and solve for y. For example, if one line is y = 3x - 5 and another line is y = -2x + 7, then you can set 3x - 5 = -2x + 7 and solve for x:

3x - 5 = -2x + 7

5x = 12

x = 12/5

Then, plug x = 12/5 into either equation and solve for y:

y = 3(12/5) - 5

y = 36/5 - 25/5

y = 11/5

Therefore, the point of intersection is (12/5, 11/5).

If one of the lines has a given angle, such as 41 degrees, then you can use trigonometry to find its equation. For example, if one line passes through the origin and has an angle of 41 degrees with the positive x-axis, then you can use the slope formula to find its equation:

slope = tan(41 degrees) ≈ 0.87

y = mx + b

y = 0.87x + 0

Then, you can use the same method as before to find the point of intersection with another line.
