The number of items, n, made in 1 hour by a machine is given by n=30/t, t is the time in minutes the machine takes to make one item. The value of r changes for different types of item. On the grid, plot the points that would be used to draw the graph of n = 30/t for values of t from 1 to 4

Answers

The equation n = 30/t is an illustration of an inverse variation

The points on the graph are: (1,30), (2,15), (3,10) and (4,7.5)

How to plot the graph?

The equation is given as:

n = 30/t

When t = 1, we have:

n = 30/1

n = 30

When t = 2, we have:

n = 30/2

n = 15

When t = 3, we have:

n = 30/3

n = 10

When t = 4, we have:

n = 30/4

n = 7.5

So the points on the graph are:

(1,30), (2,15), (3,10) and (4,7.5)

See attachment for the graph of the equation n = 30/t

Hi!

The area of the entire figure is 76 units squared.

NOTE: This question has two different shapes: a rectangle, and a triangle.

Rectangle Formula:

Length * Width = Area

[tex]LW=A[/tex]

Triangle Formula

(Base * Height) / 2 = Area

[tex]\cfrac{bh}{2}=A[/tex]

Let's first get the rectangle's area:

[tex]LW=A[/tex]

[tex]8*7=A[/tex]

[tex]56=A[/tex]

The area of the rectangle is 56.

Now, for the top triangle:

[tex]\cfrac{bh}{2} =A[/tex]

[tex]\cfrac{8*2}{2} =A[/tex]

[tex]8=A[/tex]

The area of the top triangle is 8.

Now, for the bottom triangle.

[tex]\cfrac{bh}{2} =A[/tex]

[tex]\cfrac{8*3}{2} =A[/tex]

[tex]12=A[/tex]

The area of the bottom triangle is 12.

Now, add them all together:

[tex]56+8+12=76[/tex]

A composite figure is formed by combining a square and a triangle. Its total area is 49.5 ft. The area of the
triangle is 33.5 ft. What is the length of each side of the square? Complete the explanation.
The area of the square is
it?, so each side of the square is
ft.

Answers

Answer:

The length of each side of square is 5ft.

Step-by-step explanation:

A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.

The area of the triangle is 7.5ft squared.Area of combined figure - area of triangle = area of square.

32.5 ft squared - 7.5 ft squared = 25 ft squared.

So, area of square = 25 ft squared.

Now, by putting the formula for getting the length of each side:

Let the side = a.

Area of square = 25 ft squared

Area of square = a²

Using square root both sides we get:

So, the side = 5 ft.

Therefore, the length of each side of square is 5ft.

Dale wants to order business cards for his new job.

• Company A charges a flat fee of $0.15 per card.

• Company B charges $0.10 per card plus an additional $10.00 for delivery

Write an inequality for the amount of business cards, c, that Dale would need to buy for Company to be cheaper

Answers

Dale would need to buy more than 200 cards for Company B to be cheaper.

What is inequality?

Inequality is defined as the relation which makes a non-equal comparison between two given functions.

Company A charges a flat fee of $0.15 per card.

Company B charges $0.10 per card plus an additional $10.00 for delivery

Let x = number of cards

Company A charges = $0.15x

Company B charges = $10.00 + $0.10x

For company B to be the cheaper option      ( B < A )

     $10.00 + $0.10x  <  $0.15x

     $10.00  <  $0.05x      

subtracting positive from both sides to retains the sense of the inequality and x is positive

       200 < x      

       x > 200    

 

So, Dale would need to buy more than 200 cards for Company B to be cheaper.

The swimming pool is 10 meters long and 5 meters wide, and Martina's family wants the water to be 2 meters deep. Water from the garden hose flows at a rate of 2,500 liters, or 2.5 cubic meters, per hour.

Find the required water volume using the volume of prism formula

V = lwhV = 10*5*2 = 100 m³

Find the time required

100/2.5 = 40 hours

Answer:

40 hours

Step-by-step explanation:

The swimming pool can be modeled as a rectangular prism.

Volume of a rectangular prism

  [tex]V = lwh[/tex]

where:

l = lengthw = widthh = height

First, calculate the volume of water needed:

Given:

l = 10 mw = 5 mh = 2 m

Substitute the given values into the formula and solve for V:

[tex]\implies V=10 \cdot 5 \cdot 2=100\:\: \sf m^3[/tex]

If the water flows as a rate of 2.5 m³/h, divide the volume by the rate to calculate how long it will take to fill the pool:

[tex]\implies \sf Time=\dfrac{Volume}{rate}[/tex]

[tex]\implies \sf Time=\dfrac{100}{2.5}[/tex]

[tex]\implies \sf Time=40\:\:hours[/tex]
