The value of x as shown in the straight line is 32

An equation is an expression showing the relationship between numbers and variables.

An angle is formed when two lines intersect at a point. The sum of angles in a straight line is 180 degrees.

From the diagram:

(3x - 4) + (3x - 8) = 180° (sum of angle in a straight line)

3x + 3x - 4 - 8 = 180

6x - 12 = 180

6x = 192

x = 32

Amelia cut a 168 inch long ribbon into 6 equal part. Patrick cut a 14 foot long ribbon into 7 equal piece.

Amelia's ribbon pieces were 28 inches long each. Patrick's ribbon pieces were 2 feet long each.

Amelia's ribbon:

To calculate how long each piece of ribbon is, we need to divide 168 inches (the total length of the ribbon) by 6 (the number of pieces).

168 ÷ 6 = 28

Therefore, Amelia's ribbon pieces were 28 inches long each.

Patrick's ribbon:

To calculate how long each piece of ribbon is, we need to divide 14 feet (the total length of the ribbon) by 7 (the number of pieces).

14 ÷ 7 = 2

Since 1 foot is equal to 12 inches, we can convert 2 feet to 24 inches.

Therefore, Patrick's ribbon pieces were 2 feet (or 24 inches) long each.

There are 364 solutions to the given inequality: x1 + x2 + x3 <= 11.

To get the solution of the inequality x1 + x2 + x3 <= 11, we first need to include an additional variable in the inequation to write in as an equation.

Therefore, let the additional variable be x4.

Thus, equation is x1 + x2 + x3 + x4 = 11

The number of solutions of an equation can be calculated by the formula,

[tex]( \left \ {{n+ r - 1} \atop {n}} \right.)[/tex], where n is the constant value of the equation and r is the number of variables in the equation.

In this case, n = 11 and r = 4

Therefore,

[tex]( \left \ {{n+ r - 1} \atop {n}} \right.)[/tex] = [tex]( \left \ {{11+ 4 - 1} \atop {11}} \right.)[/tex] = [tex]( \left \ {{14} \atop {3}} \right.)[/tex]

= 14 * 13 * 12 * 11!/(3 * 2 * 1 * 11!)

=2184/6 = 364

Therefore, there are 364 possible solutions of the inequality.

x/sin 45 = 4√22/sin 90

CB = 4√22/sin 90 × sin 45

CB = 4√11

or

CB = √(4√22)²-(4√11)²

= 4√11

Answer:

CB = AC = 4√11

Step-by-step explanation:

We know that the sum of the angles of a triangle is 180°. If angle A = 45° and C = 90°, then angle B = 180° - 90° - 45° = 45°. This shows us that the triangle is isosceles and the leg AC is equal to the leg CB.

Consequently: CB = AC = 4√11

If we didn't know the length of AC, then it can be calculated from the hypotenuse:

AC² + CB² = AB²
2 * CB² = (4√22)²
CB² = (4√22)² / 2
CB² = 16 * 22 / 2
CB = √(16 * 11)
CB = 4√11

Since b and g are the numbers of boys and girls in class b + 3g is equal to [tex]b^3 - 3b^2 + 5g^2 - 3g + 2b[/tex]

We can use the concept of combination to determine the value of b + 3g.

The number of ways to choose 3 boys from b boys and 2 girls from g girls is:

(b choose 3) x (g choose 2) = (b! / (3!(b-3)!) ) x (g! / (2!(g-2)!) ) = (b x (b-1)(b-2))/(321) x (g(g-1))/(2 x 1)

We know that this is equal to 168, so we can set up the equation:

(b x (b-1)(b-2))/(321) x (g(g-1))/(2 x 1) = 168

We can solve this equation to find the value of b + 3g. Since b and g are the numbers of boys and girls in the class, we know that b + g is the total number of students in the class.

So we can simplify the equation as:

(b x (b-1)(b-2)) x (g(g-1)) = 32121 x 168

and rearrange it to:

[tex](b^3 - 3b^2 + 2b) * (g^2 - g) = 1008[/tex]

[tex]= b^3 - 3b^2 + 2b = 1008 / (g^2 - g)b + 3g \\= (b^3 - 3b^2 + 2b) + 3(g^2 - g) \\= b^3 - 3b^2 + 2b + 3g^2 - 3g \\= b^3 - 3b^2 + 5g^2 - 3g + 2b[/tex]

So we can see that b + 3g is equal to b^3 - 3b^2 + 5g^2 - 3g + 2b. However, the exact value cannot be determined without the specific values of b and g.

The distance between the pair of points with the coordinates ( 3, 4 ) and (0, 0) is given by 5 units.

As given in the question,

Given pair of points with the coordinates are as follow :

( x₁ , y₁ ) = ( 3,4 )

( x₂ , y₂ ) = ( 0, 0 )

General formula to determine the distance between two pair of points with the coordinates is :

= √( y₂ - y₁ )² + (x₂ - x₁ )²

Now, substitute the values of the coordinates to find the distance between two pair of points :

= √ ( 0 - 4 )² + ( 0 - 3 )²

= √4² + 3²

= √16 + 9

= √25

= 5 units.

Answer:

x = 5

Step-by-step explanation:

Angles on a straight line add up to 180, so add up the angles and equate to 180:

9x + 85 + 10x = 180

Now we can solve for x by simplifying further:

19x + 85 = 180

Subtract 85 on both sides:

19x + 85 - 85 = 180 - 85

19x = 95

Divide 19 on both sides which cancels out the 19 on the left:

x = 95/19 = 5

P(French and English) = P(French) x P(English|French)

We know that P(French) = 64% and P(English|French) is the probability of someone speaking English given that they already speak French, which is 58%. So we can plug these values into the formula:

P(French and English) = 64% x 58% = 37.12%
