A photocopy machine can print 735 copies in 7 minutes.what is the rate at which the machine prints the copies per minute

11111nata11111 [884]

The copy machine makes 105 copies per minutes.

Step-by-step explanation:

Given,

Copies printed by photocopy machine = 735

Time taken by machine = 7 minutes

To find the unit rate in terms of minutes, we will divide the copies printed by machine by the time taken.

Copies printed in one minute = $\frac{735}{7}$

Copies printed in one minute = 105 copies

The copy machine makes 105 copies per minutes.

The table shows the relationship between the number of minutes that a hose

Marina86 [1]

Answer:

(C)The relationship is multiplicative because the number of gallons can be

found by multiplying the number of minutes by 8.

Step-by-step explanation:

Given the table below which shows the relationship between the number of minutes that a hose has been on and the number of gallons of water that have been added to a plastic pool.

$\left|\begin{array}{c|c}$Minutes Hose On&$Gallons of Water in Pool\\-------&-------\\0&0\\5&40\\10&80\\15&120\\20&160\end{array}\right|$

We can see that if we multiply the first column by 8, we will obtain the second column. Therefore the relationship is multiplicative because the number of gallons can be found by multiplying the number of minutes by 8.

The correct option is C.

Check the picture below

notice, using the 30-60-90 rule, since that triangle is a 30-60-90 triangle, we get 11 = 2x

REINFORCE Tickets to the zoo cost $18 for adults and $8.25 for children. One day, the zoo sold 2,300 tickets and collected $30,1

jenyasd209 [6]

Given:

The cost of adults ticket = $18

The cost of children's ticket = $8.25

Total tickets = 2300

Total revenue = $30,168.

To find:

The number of children and number of adults attended the zoo that day.

Solution:

Let x be the number of children and y be the number of adults.

Equation for tickets: $x+y=2300$ ...(i)

Equation for revenue: $18x+8.25y=30168$ ...(ii)

Plot the graphs of the given equations on a coordinate plane as shown below.

From the graph it is clear that the graph of both equations intersect each other at (1148,1152).

It means the number of adults is 1148 and the number of children is 1152.

It can be solved algebraically as shown below:

Substitute the value of y in (ii) from (i).

$18x+8.25(2300-x)=30168$

$18x+18975-8.25x=30168$

$9.75x=30168-18975$

$9.75x=11193$

Divide both sides by 9.75.

$x=\dfrac{11193}{9.75}$

$x=1148$

Putting $x=1148$ in (i), we get

$1148+y=2300$

$y=2300-1148$

$y=1152$

Therefore, the number of adults is 1148 and the number of children is 1152.

I will give you Brainlest if you get it right

Note that no diagram is drawn to scale.

If the diagram in the first picture is further worked upon, we have polygon ABCDE.

Note also that line AD = 18in and line MD = 10in.
This simply means the line Am = AD - MD = 8in.

We have the height of the triangle needed to solve for the area of the triangle. Area of Triangle = 1/2×b×h
Where b is length base of the triangle and h is the length of height of the triangle.
We still need b to find the Area.

Note also that two opposite sides of parallelograms are equal. This implies that line DC = line EB which is equal to 14in.
In the third image, you can see this. Half the length of the side of the parallelogram is needed. This means 14/2 = 7in.

We can now solve for the Area of the triangle.
$Area = \frac{1}{2} (b \times h)$
$Area = \frac{1}{2} (7 \times 8)$
$Area = 28$
We have the are of the triangle to be 28in. Multiply this by 3 to find the total area of all three triangles since the three triangles are identical. Thus,
Total Area of all Triangles = 28×3 = 76in

Now, find the area of the two parallelograms.
Area of parallelogram EBCD = bh

Where b is the length of the base side and h is the height.
Hence from the diagram,
$Area = 14 \times 10 \\ Area = 140$
Area of parallelogram EBCD is 140in.

Total Area of both Parallelograms will be 140 ×2= 280in since both are identical.

To find the Total Area of the tile pattern add the area of the triangles and the Parallelograms. This is 76 + 280 =356in.

Your answer is 356in.
