Answer:

[tex]\large\boxed{Q6.\ \sin X\approx0.778}\\\boxed{Q7.\ x\approx5.9}[/tex]

Step-by-step explanation:

Q6.

[tex]\sin\theta=\dfrac{opposite}{hypotenuse}[/tex]

We have

[tex]opposite=14\\\\hypotenuse=18[/tex]

Substitute:

[tex]\sin X=\dfrac{14}{18}=\dfrac{14:2}{18:2}=\dfrac{7}{9}=0.777...\approx0.778[/tex]

Q7.

Use sine.

We have

[tex]opposite=x\\\\hypotenuse=8\\\\\alpha=48^o\\\\\sin48^o\approx0.7431[/tex]

Substitute:

[tex]\dfrac{x}{8}=0.7431[/tex]               multiply both sides by 8

[tex]x=5.9448\to x\approx5.9[/tex]

Answer: The answer is 12.6 Meters Squared

You get that from multiplying 120 to 3.5 and 2.5 . After doing that you will get 420 cm and 300 cm. Knowing that a meter is 100 cm you will get 4.2 meters and 3 meters. To find the area of the kitchen space you will multiple 4.2 and 3 meters together and get 12.6 Meters, therefore 12.6 meters squared is the area of the kitchen floor.

Final answer:

To find w from the equation 3w - 4z = 8, add 4z to both sides, and then divide by 3 to isolate w, giving w = (4z + 8) / 3.

Explanation:

The equation 3w - 4z = 8 is a linear equation in two variables (w and z). To find w in terms of z, you need to isolate w on one side of the equation. Here is the process step by step:

Add 4z to both sides of the equation: 3w - 4z + 4z = 8 + 4z.

Simplify the equation: 3w = 4z + 8.

Divide every term by 3 to solve for w: w = (4z + 8) / 3.

So, w is equal to (4z + 8) / 3 when isolated from the given equation.

Answer:

0.5r

Step-by-step explanation:

If Jerry took half the time Macy did then that means Macy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Macy goes half as slow and takes twice as long to get there.

The average speed of Marcy in miles per hour is 0.5r.

If Jerry took half the time Marcy did then that means Marcy took twice as long as Jerry. If Jerry’s speed was r then Macy’s speed is 0.5r or half the speed of Jerry. This will mean Marcy goes half as slow and takes twice as long to get there.

If circle with center O has a radius of 18 centimeters. If the length of arc AB = 6π centimeters then measure of x is 60°

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given,

Circle with centre O,

Radius of circle=18 centimeters

length of arc AB = 6π centimeters

We need to find the measure  θ  of x

We have a formula to find the length of arc.

Length of an Arc = θ × (π/180) × r

Apply the given values in formula

6π=θ × (π/180) × 18

π gets cancelled on both the sides

6=θ/10

θ=60°

Hence if circle with center O has a radius of 18 centimeters. If the length of arc AB = 6π centimeters then measure of x is 60°

What is segment ab? is there a picture that is supposed to go with it?

Answer:  The required co-ordinates of point M are (8, 9).

Step-by-step explanation:  Given that the point M divides segment AB into a ratio of 2 : 3, where A is at (0, 15) and B is at (20, 0).

We are to find the co-ordinates of point M.

We know that

the co-ordinates of a point that divides the line segment joining the points (a, b) and (c, d) are given by

[tex]\left(\dfrac{mc+na}{m+n},\dfrac{md+nb}{m+n}\right).[/tex]

For the given division, (a, b) = (0, 15), (c, d) = (20, 0) and m : n = 2 : 3.

Therefore, the co-ordinates of point M are given by

[tex]\left(\dfrac{2\times20+3\times0}{2+3},\dfrac{2\times0+3\times15}{2+3}\right)\\\\\\=\left(\dfrac{40}{5},\dfrac{45}{5}\right)\\\\\\=\left(8,9).[/tex]

Thus, the required co-ordinates of point M are (8, 9).

Answer:

128

Step-by-step explanation:

Method A.

The volume of the prism is 2 cubic units.

Each cube has side length of 1/4 unit.

The volume of each cube is (1/4)^3 cubic unit.

The volume of each cube is 1/64 cubic unit.

To find the number of cubes that fit in the prism, we divide the volume of the prism by the volume of one cube.

(2 cubic units)/(1/64 cubic units) =

= 2/(1/64)

= 2 * 64

= 128

Method B.

Imagine that the prism has side lengths 1 unit, 1 unit, and 2 units (which does result in a 2 cubic unit volume.) Since each cube has side length 1/4 unit, then you can fit 4 cubes by 4 cubes by 8 cubes in the prism. Then the number of cubes is: 4 * 4 * 8 = 128

He right answer is 128

Answer:

3(2b+3)^2=36

(2b+3)^2=12

2b+3=+2 radical3

2b+3= 2 radical 3

b=- radical 3 -3 over 2

b= radical 3- 3 over 2

b=- radical 3 - 3 over 2

Answer:

The answer is A

Step-by-step explanation:

To solve the problem, set up two equations: X + Y = 12 and X = 2Y. Using the substitution method, replace X with 2Y in the first equation to find Y = 4, and subsequently find X = 8.

The problem given to us involves finding two numbers, X and Y, given that the sum of these two numbers is 12 and the first number, X, is twice the second number, Y. To solve for X and Y, we can set up a system of two linear equations.

The first equation comes from the sum of the two numbers:

X + Y = 12

The second equation comes from the statement that X is twice Y:

X = 2Y

Now we have a system of equations:

One method to find solutions for X and Y is by substitution. We can substitute 2Y in place of X in the first equation:

Now that we know Y is 4, we can find X using the second equation:

The two numbers are X = 8 and Y = 4.

Answer:

y = (-5/4)x + 12.25

Step-by-step explanation:

Slope intercept form:

y = mx + b

Slope form:

m = (y₂ - y₁)/(x₂ - x₁)

Let:

(x₁ , y₁) = (9 , 1)

(x₂ , y₂) = (5 , 6)

Plug in the corresponding numbers to the corresponding variables.

m = (6 - 1)/(5 - 9)

Simplify.

m = (5)/(-4)

Your slope is -5/4

Plug in -5/4 for m in the slope-intercept form equation, and use a point to solve for b. For example, we will use (9, 1):

y = mx + b

y = (-5/4)x + b

(1) = (-5/4)(9) + b

Simplify.

1 = (-11.25) + b

Isolate the variable, b. Note the equal sign, what you do to one side, you do to the other. Add 11.25 to both sides.

1 + (11.25) = -11.25 (+11.25) + b

1 + 11.25 = b

b = 12.25

your y-intercept is 12.25

Plug in the corresponding numbers to the corresponding variables.

y = mx + b

m = -5/4

b = 12.25

y = (-5/4)x + 12.25 is your answer.

Answer:

C

Step-by-step explanation:

By definition a proportion should be equal to each other and can be multiplied by the same number on the numerator and the denominator to make the second fraction.

[tex]\frac{x_1}{y_1}=\frac{x_2}{y_2}[/tex]

[tex]\frac{x_1}{y_1}*\frac{z}{z}=\frac{x_2}{y_2}[/tex]

A

[tex]\frac{3}{7}*\frac{3}{3}=\frac{9}{21}[/tex]

So it is a proportion.

B

[tex]\frac{24}{56}/\frac{8}{8}=\frac{3}{7}[/tex]

So it is a proportion.

C

[tex]\frac{3}{7}*\frac{3}{4}=\frac{9}{28}[/tex]

So it is not a proportion.

D

[tex]\frac{3}{7}*\frac{4}{4}=\frac{12}{28}[/tex]

A slope is also known as the gradient of a line. The correct option is B.

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The slope of the line that is passing through (-2, 6) and (4, 6) can be calculated as,

Slope = (6-6)/(-2-4) = 0/(-6)

Answer:

8.717 both the sides

Step-by-step explanation:

Given:

Let ABC be the given triangle with

angle A= 55

angle B=55

angle C= 70

side across angle C, c= 10 inches

side across angle B, b =?

aide across angle A,a=?

Now using the law of sin to find a and b:

                a/sinA=c/sinC

                a= (c/sinC)(sinA)

Putting the values:

                a= (10/sin70)(sin55)

                a= 8.717

As the given triangle is isosceles so side a=b

hence a=b= 8.717 inches !
