Step-by-step explanation:

We are told in the question that:

The total number of students going = 45 students

The number of year 8 students going for the ski trip = 28 students

The proportion is :

28/45

Converting this proportion to a percentage.

28/45 × 100

= 0.6222222222222222 × 100

62.222222222%

Answer:

C

Step-by-step explanation:

Looking at the graph, we can see that the graph crosses the y-axis at y=2.

Hence, our y-intercept should be 2.

Therefore, we can eliminate A.

We also notice that the graph is downwards sloping.

Therefore, our slope is negative.

So, we can eliminate B.

Therefore, our answer must be C.

Step-by-step explanation:

The image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin is  (-1, -1).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

Given, the image of (-3, -3) after dilation by a scale factor of 1/3 centered at the origin will be,

= (-3/3, -3/3).

= (-1, -1).

It has been shrinked by a factor of three the image became smaller.

Answer:

Number of moles = 41.67 (Approx)

Number of carbon atom = 250.97 x 10²³ (Approx)

Step-by-step explanation:

Given:

Amount of carbon = 500 g

Find:

Number of moles

Number of carbon atom

Computation:

Number of moles = 500 / Atomic number of weight

Number of moles = 500 / 12

Number of moles = 41.67 (Approx)

Number of carbon atom = Number of moles x Avogadro number

Number of carbon atom = 41.67 x 6.023 x 10²³

Number of carbon atom = 250.97 x 10²³ (Approx)

The constant of proportionality is 0.54

Step-by-step explanation:

Given:

P = 0.54n

Where,

P = price of pears

n = number of pears

What is the constant of proportionality (unit rate)?

The constant of proportionality is 0.54

This means a unit of pears cost $0.54

If the number of pears bought, n = 50

Then,

P = 0.54n

When n = 50

P = 0.54(50)

= 27

P = 27 when n = 50

The correct answer is:

The constant of proportionality is 0.54

Answer:

The value of x = 4 if g(x) = 6

Step-by-step explanation:

Given the function

[tex]g(x) = 3(x - 2)[/tex]

as

[tex]g(x) = 6[/tex]

so putting the value of [tex]g(x) = 6[/tex] in the function

[tex]g(x) = 3(x - 2)[/tex]

[tex]6 = 3(x-2)[/tex]

Switch sides and divide both sides by 3

[tex]\frac{3\left(x-2\right)}{3}=\frac{6}{3}[/tex]

[tex]x-2=2[/tex]

[tex]x=4[/tex]

Therefore, the value of x = 4 if g(x) = 6

Step-by-step explanation:

At a grocery store 3 cans of soup cost $6.90

3 cans = 6.90

1 can= 6.90/3

1 can = $2.3

Therefore the cost of 10 cans can be calculated as follows

1 can= $2.3

10 cans= 10×2.3

= $23

Hence 10 cans will cost $23

Answer:

Step-by-step explanation:

Are there any choices?

2(4x+1)

8x+2

The expression equivalent of 2(4x+1)​ would be; 8x+2

Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.

To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.

We need to find the expression into an equivalent.

Therefore, given expression is

2(4x+1)​

This expression could also be given by;

2(4x+1)​ = 2(4x ) + 2

Now, we know that:

2(4x+1)​ = 8x+2

Hence, the expression equivalent of 2(4x+1)​ would be; 8x+2

211264-100x = 38.5x

138.5x = 211264

x = 211264/138.5
