Answer:

The slope of the line y=3 is 0

Step-by-step explanation:

We need to find the slope of the line y =3

the general form of the equation is

y = mx+b

where m is the slope and b is the y-intercept.

Looking at the given equation

y=3

We can write it as

y =0(x) + 3

So, the slope of the line y=3 is 0

Answer:

The slope is 0

Step-by-step explanation:

Note that [tex]y = 3[/tex] is the equation of a horizontal line that intersects the y-axis at point (0, 3).

The slope of a line is a measure of how the variable y varies when x increases or decreases. In this case, the variable y always has the same value. Therefore the slope is zero.

All horizontal lines have slope [tex]m = 0[/tex]

Answer:

Perimeter: 174.8 m

Area: 1,394 sq m

Step-by-step explanation:

First, the perimeter.

Before we start, let's calculate the circumference of the half-circles at the ends of the field.

The measurement says 2,000 cm, so let's convert it to 20 m for ease.

Circumference of a circle: πd, where d = diameter.. in our case d = 20 m

Circumference of a 20m diameter circle: 20π = 62.8 m

We have 2 half circles... so the perimeter of each half-circle will be: 31.4 m

We also have 800 cm measurement for the "height" of the seating areas... let's convert that in 8 m

We also need to find out the space between the seating area...  We know the whole rectangular pitch is 40 m, then we have to subtract the width of both seating areas (20 and 15 m)... so the space between them is 5m

So, starting with the upper left corner of the rectangular pitch, and working our way clockwise, we encounter the following lengths:

P = 40 + 31.4 + 8 + 10 + 8 + 5 + 8 + 25 + 8 + 31.4 = 174.8 m

The total perimeter is then of 174.8 m

For the area, we need to calculate the area of all forms:

Large rectangular pitch:

LR = 40 x 20 = 800 sq m

The two half circles, form a circle, so A = πr², where r is the radius, which is half the diameter.

AC = π (10)² = 100 π = 314 sq m

Then the seating areas:

SA1 = 25 x 8 = 200 sq m

SA2 = 10 x 8 - 80 sq m

Then, we add up everything:

TA = LR + AC + SA1 + SA2

TA = 800 + 314 + 200 + 80 = 1,394 sq m

Answer:

width = 14 , length = 42

Step-by-step explanation:

Here we have to find the width of the rectangle using the fact that length is 3 times the width and perimeter is given

Let the length of the rectangle = x

Hence the width of the rectangle = 3 x

The formula for the perimeter is

P=2(l+b)

Given P = 112

Hence

112=2(l+b)

l+b=56

substituting values of l and b in this

x+3x= 56

4x=56

x=14

Hence width = 14 cms

length = 3*14 = 42 cms

Graph Function

  A         f(x) = x

  B        f(x) = x^2

  C         f(x) = x^3

  D         f(x) = √(x - 1)

  E          f(x) = 1/x

To match each graph with the function it represents, we need to consider the shape of the graph and the equation of the function.

Graph A: This graph is a straight line that passes through the origin and has a slope of 1.

This indicates that the function is linear and has the following equation:

Graph B: This graph is a parabola that opens upwards and has its vertex at the origin.

This indicates that the function is quadratic and has the following equation:

f(x) = x^2

Graph C: This graph is a cubic function that opens upwards and has a point of inflection at the origin.

This indicates that the function has the following equation:

f(x) = x^3

Graph D: This graph is a square root function. It has a vertical asymptote at x = 1 and a horizontal asymptote at y = 1.

This indicates that the function has the following equation:

f(x) = √(x - 1)

Graph E: This graph is a reciprocal function. It has a vertical asymptote at x = 0 and a horizontal asymptote at y = 0.

This indicates that the function has the following equation:

f(x) = 1/x

Answer:

y = 14x -30

Step-by-step explanation:

The slope intercept form is:

y = mx + b,

Slope intercept form is useful for finding the slope and y intercept of a line, hence why it is called "slope intercept" because it is easy to see the slope and the y intercept of a line in this form. Since the slope denoted by m, and y intercept denoted by b are clearly given.

y + 2 = 7(2x - 4)

Distribute 7 across the parentheses by multiplying x and 2x and 4 by 7.

y+2 = 14x - 28

subtract 2 from both sides. This cancels the 2 on the left and moves it to the right, while keeping the equation balanced.

y+2 -2 = 14x - 28 -2

y  = 14x - 30

y = 14x -30

As you can see our y = 14x -30 now looks like the point slope equation we had above. m = 14, and  b = -30. This means the line goes up 14 for every single unit you move to the right, and intersects the y axis at  (0, -30).

Answer:  [tex]y=\frac{1}{30}x+1[/tex]

Step-by-step explanation:

The equation of the line in Slope-Intercept form is:

[tex]y=mx+b[/tex]

Where "m" is the slope and "b" is the y-intercept.

The slope of the line can be calculated with this formula:

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

Pick to  points of the given line. You can choose the point (60,3) and the point (30,2).

Then, substituting into the formula, you get:

 [tex]m=\frac{2-3}{30-60}=\frac{1}{30}[/tex]

You can observe in the graph that the line intercepts the y-axis at the point (0,1), therefore "b" is:

[tex]b=1[/tex]

Substituting the slope and the y-intercept found into  [tex]y=mx+b[/tex], you get the equation of this line:

 [tex]y=\frac{1}{30}x+1[/tex]

Where "y" represents the Height (1,000 ft) and "x" represents the Time in seconds.

Answer:

The equation of the given line is :y = 0.04x + 0.6.

Step-by-step explanation:

From the given data , we can select two coordinates to determine the equation of the given line:

Let the point be [tex](10,1),(60,3)[/tex]

The equation of the line will be determined by the help of point slope form:

Slope of the line = [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex](y-y_1)=m(x-x_1)[/tex]

The equation of the line is :

[tex]m=\frac{3-1}{60-10}=\frac{2}{50}=0.04[/tex]

[tex](y-1)=0.04(x-10)[/tex]

[tex]y-1=0.04x-0.4[/tex]

[tex]y=0.04x+0.6[/tex]

The equation of the given line is :y = 0.04x + 0.6.

Answer:

[tex]y = \frac{3}{13}x-\frac{2}{13}[/tex]

Step-by-step explanation:

Move 3x to the other side, since 3x is being moved to the other side the sign will change from a positive to a negative

[tex]-13y = -3x+2[/tex]

Divide both sides by 13

[tex]y = \frac{3}{13}x-\frac{2}{13}[/tex]

Hey there! :)

3x - 13y = 2 ; solve for y.

In order to solve for y, we must isolate it by getting it onto its own side. We can do this by subtracting 3x from both sides.

-13y = -3x + 2

Then, divide both sides by -13.

-13y ÷ -13 = (-3x + 2) ÷ -13

Simplify.

y = 3/13x - 2/13

Therefore, [tex]y = \frac{3}{13}x- \frac{2}{13}[/tex]

Hope this helped! :)

The percentage of pastrami sold was 40 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Number of sandwiches sold in one day = 90

Number of pastrami in 90 sandwiches = 36

To calculate the percentage of pastrami in sandwiches , we divide the total number pastrami to the total number of sandwiches and multiply by 100

Answer:

We know

1 jar = 500 buttons

5 people bring 330 buttons EACH

We can find/solve by...

people x buttons = total buttons

total buttons / 500 = number of jars needed

So..

5 x 330 = 1650

1650 / 500 = 3.3

Your answer:

4 jars

Explanation

It's impossible to have 3.3 jars, so you must round up.

Step-by-step explanation:

The number of jar necessary to hold all buttons is 4 jars.

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Given that

1 jar holds = 500 buttons

5 people = 330 buttons each

So,

Total buttons 5 people bring

=330*5

=1650 buttons

Now,

number of jars needed= total buttons/500

number of jars needed= 1650/500

Step-by-step explanation:

Given rates of work:

Peter = 5 hours / room

Paul = 6 hours / room

Neil = 7.5 hours / room

Mary = 3.75 hours / room

Recall the formula for combined rate for two individuals A & B is given as

Combined rate = (A's rate x B's rate) / (A's rate + B's rate)

In our case , the combined rate is given to be 3 hours, so we must find a combination of rate A and rate B that will give us 3 hours.

If you try all the combinations in the above formula, we will find that if we substitute Peter's and Neil's rates into the formula, we will get exactly 3 hours.

Combined rate for Peter and Neil

= (Peter's rate x Neil's rate) / (Peter's rate + Neil's rate)

= (5 x 7.5) / (5+7.5) = 3 hours to complete 1 room

No other combination gives exactly 3 hours.
