Answers

Answer 1

Proportionality denotes a linear relationship between two quantities or variables.

A.  Table is mentioned below.

B. Yes, it is a proportional relation.

C. y = 1/24 x

What is meant by proportional?A linear relationship between two quantities or variables is referred to as proportionality. If one quantity doubles in size, the other does as well; if one variable decreases to one-tenth of its previous value, the other does as well.If the ratio or relationship between y and x is the same or constant, the quantities are proportional: y/x = k, where k is the proportionality constant.When two quantities are proportional, it means that as one increases, so does the other, and the ratio of the quantities remains constant across all values.Consider a circle's circumference and diameter; the ratio of the two values equals pi.

Therefore,

Part C : We know that,

1 day = 24 hours,

⇒ 1 hour = 1/24 day

As a result, the number of days in x hours (say y) = hours number of days in each hour

⇒ y = 1/24 x

Which is an equation of line.

Part A :

Hours       1              2           3           4          5      

Days       1/24       1/12        1/8         1/6       5/24

Part B :

∵ a line passes through the origin always shows a proportional relation,

Since, for (0, 0),

0 = 1/24 (0) ( True )

i.e. there is a proportional relation between number of days and number of hours.

What is the enzyme substrate reaction?

The enzyme is called a catalyst as it has an active site where the substrate can bind and convert into the product. Here in the graph the enzyme is amylase, and its substrate is starch. When there is an excess of enzymes in the solution, they can convert it into a product till substrates are available. If the substrate runs out, the reaction will come stop.

A community hall is in the shape of a cuboid.
The hall is 40 m long, 15m wide and
3 m high.

The community hall needs re-decorating
with new paint for the walls and ceiling,
and new tiles on the floor.

A 10 litre tin of paint covers 25 m² and costs £10.

Work out the total cost of paint needed
to re-decorate the community hall.

Answers

The total cost of painting is $564.

What is surface area of cuboid ?

  A cuboid is a three-dimensional figure enclosed by six rectangular planes, each of which has a different size in terms of length, breadth, and height. Anything in the shape of a rectangle, such as a box, brick, or other object, may be a cuboid if you look about. When viewed from any of the ends, a cuboid (3-dimensional) can be seen to be made up of different-sized rectangles (2-dimensional). A cuboid's area is its surface because it is a solid with three dimensions. Since a cuboid's faces are rectangular, its area may be determined using the formula for the area of a rectangle.

Total Surface Area of a Cuboid (TSA) = 2 (lw + wh + lh) square units

We have been given that a community hall is in the shape of a cuboid. The hall is 40m long 15m high and 3m wide.

The paint will be required for 4 walls and ceiling.

Let us find area of walls and ceiling.

Area of walls and ceiling = 2( 40*15) + 2(3*15) + (40*3)

=> Area of walls and ceiling = 2(600)+2(45)+120

=> Area of walls and ceiling = 1200+90+120

=> Area of walls and ceiling = 1410 [tex]m^2[/tex]

Therefore, the area of walls and ceiling is 1410 square meters.

Here Cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter.

Then total cost of paint = 10*[tex]\frac{1410}{25}[/tex] = 10*56.4 = $564.

Hence cost of paint is $564.

Which of these strategies would eliminate a variable in the system of equations?

Answers

The strategy which would eliminate a variable in the system of equations is to multiply the top equation by 3 ,multiply the bottom equation by -2 then add the equation and is denoted as option B.

What is Equation?

This is a mathematical term which is made up of two expressions and is connected by an equal sign.

In the example given below:

2x + 8y = -3

3x + 6y = -4

We can multiply the top by 3 and the bottom by -2 which will result in:

6x + 24y = -9

-6x - 12y = 8

They are then added to each other to give:

6x - 6x + 24y - 12y = -9+8

12y = -1

y = -1/12

From this we can notice that the variable x was eliminated which is why option B is the correct choice.

Solve the equation: 4 - 2y + 3 = - 9. What is y equal to?

Answers

Answer:

b

Step-by-step explanation:

In the given equation  4 - 2y + 3 = - 9, y is equal to 8.

The equation is a statement in which the values of two mathematical expressions are equal (indicated by the sign =).

To find the value of y from the given equation

∴  4 - 2y + 3 = - 9

=> 4+3 -2y = -9

=> 7 - 2y = -9

=> 7 + 9 = 2y

=> 16 = 2y

=> 16/2 = y

=> 8 = y

What is the slope of the line created by this equation?

Answers

Answer:

-0.86

Step-by-step explanation:

What is the slope of the line created by this equation? Round your answer out to two decimal places. 6x + 7y = 5

_____________________________________________

Slope intercept form solves for y:

y = mx + b when m = slope and b = y-intercept

First, solve for y:

6x + 7y = 5

subtract 6x from both sides:

6x + 7y - 6x = 5 - 6x

7y = 5 - 6x

divide both sides by 7:

7y/7 = (5 - 6x)/7

y = 5/7 - 6/7x

rearrange right side:

y =  - 6/7x + 5/7

Back to the equation: y = mx + b when m = slope and b = y-intercept

your slope is -6/7

in decimal form, rounded to two digits: -0.86

Step-by-step explanation:

Corinne and Deanna decide to race from one corner of an open field to the other. The field is rectangular in shape, 60 meters long and 80 meters wide. Since Corinne is older and faster, she's going to run along the outside of the field, and Deanna will take the diagonal route. If Deanna can run at a rate of 5 meters per second, how fast will Corinne have to run to get there at the same time as Deanna?

Answers

Answer:

Corinna will have to run at 7 meters per second to get there at the same time as Deanna.

Step-by-step explanation:

So to find the distance of Deanna's route, you can use the Pythagorean theorem.

a^2 + b^2 = c^2

60^2 + 80^2 = 10000

c^2 = 10000

Take the square root of both sides.

c = 100

So Deanna runs 100 meters at 5 meters per second.

100/5 = 20

She runs for 20 seconds.

To find Corinne's distance, we add 60 and 80, which is 140.

To find how fast she need to run to get there in 20 seconds, you divide 140 by 20, which gets 7 (meters per second). You can also think of it like this: to run 140 meters in 20 seconds, she has to run at 140 meters per 20 seconds, which you can simplify (like a fraction) to 7/1, or just 7

Store 1, can be placed on 24 sites. Store 2 can be placed on 23 sites (since store 1 is already on site 1). Store 3 can be placed on 22 sites. Store 4 can be placed on 21 sites. Store 5 can be placed on 20 sites. Store 6 can be placed on 19 sites

So your going to add like terms and subtract at the end your answer will be C=4

Answer:

Step-by-step explanation:

6c + 14 = -5c + 4 + 9c

1) We want to first combine the c values on the right side. This would give us 6c + 14 = 4c + 4.

2) Next, we want to move the c value to one side of the equation. This means we would subtract 4c from the right side. This gives us 2c + 14 = 4.

3) We can then subtract 14 from the left side to isolate the c value. This gives us 2c = -10.

3) We can then divide both sides by 2 and get the answer for c.

This gives us c = -5.

The mean is the total sum of the values in a data set divided by the number of values of the data set.

The median of a data set is the center value when the data distribution is ordered.

Given the ordered data set as, 4, 6, x, y, and 10.

The center value is x. Therefore, the median of the data set is x.

The mean of the data = (4 + 6 + x + y + 10)/5

The mean of the data = (20 + x + y)/5

The mean and the median are equal, therefore:

(20 + x + y)/5 = x
