john because 1 yard is equal to 3 ft, 4x3=12 ft

Final answer:

Jane has more fabric than John with a difference of 24 inches.

Explanation:

To compare the amount of fabric John and Jane have, we need to convert their measurements into the same unit. Since John has 4 yards of fabric and Jane has 120 inches, we need to convert yards to inches or inches to yards.
To convert yards to inches, we know that 1 yard is equal to 36 inches. So, multiplying 4 yards by 36 inches per yard, we get 144 inches of fabric for John.
Comparing the two measurements, we can see that Jane has more fabric with 120 inches compared to John's 144 inches. The difference is 144 inches - 120 inches = 24 inches. Therefore, Jane has 24 inches more fabric than John.

The correct set of reflections that would carry triangle ABC onto itself is:

d. y-axis, x-axis, y-axis, x-axis

As per the shown graph, the coordinates of the vertices:

A(0,2)

B(2,4)

C(3,0)

We observe that the y-axis is the vertical line passing through x = 0, and the x-axis is the horizontal line passing through y = 0.

By analyzing the positions of the vertices, we can see that the triangle has rotational symmetry of 180 degrees around points (1, 2) and reflectional symmetry across both the x-axis and the y-axis.

Therefore, the correct set of reflections that would carry triangle ABC onto itself is:

Answer:

R = 50

Step-by-step explanation:

The sum of the angles of a triangle equal 180 degrees

S + R + Q = 180

x+70 + x+ 20 + x = 180

Combine like terms

3x +90 =180

Subtract 90 from each side

3x+90-90 = 180-90

3x= 90

Divide by 3

3x/3= 90/3

x = 30

We want to find angle R

R = x+20

R = 30+20

R = 50

Answer:

f(x) = x² + 9x - 22

Step-by-step explanation:

Given that x = 2 and x = - 11 are zeros, then

(x - 2) and (x + 11) are factors

and f(x) equals the product of the factors

f(x) = (x - 2)(x + 11) ← expand factors

f(x) = x² + 9x - 22 ← is a possible function

The quadratic function [tex]\( f \)[/tex] with zeros at [tex]\( x = 2 \) and \( x = -11 \)[/tex] can be written in factored form as: [tex]\[ f(x) = x^2 + 9x - 22 \][/tex]

The standard form of a quadratic function is:

[tex]\[ f(x) = ax^2 + bx + c \][/tex]

To convert the factored form to standard form, we expand the factors:

[tex]\[ f(x) = a(x^2 + 11x - 2x - 22) \] \[ f(x) = a(x^2 + 9x - 22) \] \[ f(x) = ax^2 + 9ax - 22a \][/tex]

[tex]\[ b = 9a \] \[ c = -22a \][/tex]

So, the quadratic function with zeros at [tex]\( x = 2 \) and \( x = -11 \) is:[/tex]

[tex]\[ f(x) = ax^2 + 9ax - 22a \] \[ f(x) = x^2 + 9x - 22 \][/tex]

According to the Rate of Change [Slope] Formula, m = -y₁ + y₂\-x₁ + x₂, you plug in each coordinate into the correct places and you will arrive at the above answer.

Answer:

 y = 3/7 x

Step-by-step explanation:

Slope intercept form y = mx + b

In this case 3x - 7y = 0​

7y = 3x  

 y = 3/7 x (b = 0)

Answer:

y= 0- 3x over -7

Step-by-step explanation: Slope intercept form is Y= mx+ b

Hope this helps

For this case we have that the equation of a line in the slope form intersection is given by:[tex]y = mx + b[/tex]

Where:

m: It's the slope

b: It is the cut point with the y axis.

In the green graph we observe that[tex]b = 2[/tex], then its equation is [tex]y = 5x + 2[/tex]

We have the slope of the red line substituting two points:

[tex](0,2)\\(-1,0)[/tex]

[tex]m = \frac {0-2} {- 1-0} = 2[/tex]

Thus, the red line has equation[tex]y = 2x + 3[/tex]

Finally, the blue line is [tex]y = 3x + 3[/tex]

Answer:

Green line, y = 5x + 2

Red line, y = 2x + 3

Blue line, y = 3x + 3

Answer:

1 - green line: y = 5x + 2

2 - red line: y = 3x + 3

3 - blue line: y = 2x + 3

Step-by-step explanation:

1 - green line

The graph with the green line is the easiest to match with an equation.

If you look at the graph, you see that when x = 0, the y-value is 2.

There's only one of the given equations that y = 2 when x = 0, the first one.

y = 5x + 2

y = 5 (0) + 2 = 0 + 2 = 2

It's easy to spot, because in the format y = mx + b, the b is the value of Y when x = 0, as we just demonstrated.

2 - Red line

In this case, when x = 0, y = 3.  And there are 2 equations for which it's true... which is normal because the blue line (in next graph) also passes by this point.

Then to know which equation goes with the red line graph, we have two choices...

A. determine the slope (rate of change) of the red line and see if it matches one of the equations.

B. See what value of X yields a value of 0 for Y and see where it would land on the X-axis.

The second method is faster.  If you see on the graph, when y = 0, x = -1

If we take the 2nd equation (y = 3x + 3) and we set the value of y to 0, we have:

0 = 3x + 3

-3 = 3x

x = -1

Which is exactly what we wanted to find.

So, the red line is y = 3x + 3

3. blue line

Well, there's only one answer left (y = 2x + 3), so it's easy... but let's make sure by finding the slope (method A listed for the red line above), in case your teacher would be playing tricks on you.

The slope of a line is the variation of y-value (Δy) divided by the variation of x-value (Δx).

If we take the two points where the blue line crosses the axis, we have (-1.5, 0) and (0,3).

Now, let's calculate the slope:

S = (0 - 3) / (-1.5 - 0) = -3 / -1.5 = 2

And 2 is the slope of the equation y = 2x + 3

So, we're good.

Answer:

(1/3)³c = 5

(1/27)c = 5

c = 5 × 27 = 135 cubes

The Main Answer is 135. It takes [tex]135[/tex] of the [tex]1/3[/tex] unit cubes to fill the rectangular prism.

To find out how many [tex]1/3[/tex] unit cubes it takes to fill the rectangular prism with a volume of [tex]5[/tex] cubic units, we need to divide the volume of the prism by the volume of each individual cube.

The volume of the rectangular prism is given as [tex]5[/tex] cubic units. Since the prism is a rectangular shape, we can calculate its volume using the formula:

[tex]Volume of prism=length*width*height[/tex]

Given that the side length of each cube is [tex]1/3[/tex] unit, the volume of each cube is:

[tex]Volume of cube=(side length)^{3} =(1/3)^{3}=1/27 cubic[/tex]

Now, to find out how many cubes are needed to fill the prism, we divide the volume of the prism by the volume of each cube:

[tex]Number of cubes=Volume of prism/Volume of cube \\Number of cubes=5/(1/27)\\Number of cubes=5*27\\Number of cubes=135[/tex]

So, it takes [tex]135[/tex] of the [tex]1/3[/tex] unit cubes to fill the rectangular prism.

Answer:

314 units²

Step-by-step explanation:

Centre of the circle = (0, 0)

Another point on the circle = (-6, -8)

[tex]\text {Radius = }\sqrt{(0 - (-6))^2 + (0- (-8))^2}[/tex]

[tex]\text {Radius = }\sqrt{6^2 + 8^2}[/tex]

[tex]\text {Radius = }\sqrt{100}[/tex]

[tex]\text {Radius = }10[/tex]

Area = π (10)² = 100π = 314 units²

Final answer:

The area of the circle is found by first calculating the radius using the distance formula, which is determined to be 10 units. Then, the area formula πr² is used to find that the area of the circle is 100π square units.

Explanation:

To find the area of the circle centered at the origin containing the point (-6, -8), we first need to determine the radius of the circle. The radius can be found using the distance formula for a point from the origin, which is √((-6)²+ (-8)²). After calculating the radius, we use the formula for the area of a circle, which is πr^2, to find the circle's area.

The distance from the origin to the point (-6, -8) is the radius (r) of the circle: r = √((-6)² + (-8)²) = √(36 + 64) = √100 = 10.

Now that we have the radius, we can calculate the area (A): A = πr² = π(10)² = 100π square units.

Answer:

61

Step-by-step explanation:

The first thing that you want to do is distance formula

[tex]d=(x_{2}-x_{1} )^{2} + (y_{2}-y_{1} )^{2}[/tex]

I'm going to make the start of the line at (1,1) and that means that the end of the line is at (7,6). Now, you plug these numbers into the formula.

[tex]d=(7-1 )^{2} + (6-1 )^{2}[/tex]

Then you slove

[tex]d=(6 )^{2} + (5 )^{2[/tex]

[tex]d=36 + 25[/tex]

[tex]d=61[/tex]

Distance formula: d =√(x2-x1^2 +y2-y1^2)

Find the points of the line: (2,2) and (8, 7)

Length = √((8-2)^2 + (7-2)^2)

Length = √(6^2 + 5^2)

Length = √(36+25)

Length = √61 ( exact answer) or as a decimal: 7.81
