Order the following numbers from greatest to least. Put the greatest number on the left. 1.25 5 -4.5 -2​

Answer:

P = 16x+26y units

Step-by-step explanation:

Let the length is (x+8y) units

Width = (8x-x+5y) units

We need to find the perimeter. We know that the perimeter is equal to the sum of all sides.

P = 2[(x+8y) + (8x-x+5y)]

= 2[(8x+8y+5y)]

= 2[8x+13y]

= 16x+26y

Hence, the required perimeter is 16x+26y.

Given:

The table of values.

To find:

The rate of change.

Solution:

From the given table it is clear that the rate of change is constant and function passes through two points (-1,5) and (2,-4). So, the rate of change is

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

[tex]m=\dfrac{-4-5}{2-(-1)}[/tex]

[tex]m=\dfrac{-9}{2+1}[/tex]

[tex]m=\dfrac{-9}{3}[/tex]

[tex]m=-3[/tex]

So, the rate of change is -3.

Therefore, the correct option is C.

Answer:

x=1.25, y=1.75

Step-by-step explanation:

The two triangles formed (one triangle with side lengths of 5, 7, 8 and another with sides 5+x, 10, and 7+y) are similar, because they share the same angle measures.

Now, 2 sides given that we can compare ratios with are the side with length 8, and the side with length 10. 10/8= 1.25, which is the ratio of the sides on these 2 triangles.

Now we want to find what the side '5+x' is equal to. To do that we can use our  ratio, and multiply 5 by 1.25 to find '5+x'. This is 6.25. To find x, all we need to do is subtract 5 from 6.25, which is 1.25.

Let's find y now. Do the same thing that we did with the side '5+x'; find what '7+y' is by multiplying 7 by 1.25, which is 8.75. 8.75-7= 1.75.

Hope this helps! :)

Answer:

a. 80g fish

b. 200g butter

Step-by-step explanation:

a. you have to divide it by 3 because 2 is 1/3 of 6 so 240/3 = 80g of fish.

b. multiply by 2.5 because 15 is 2.5 times 6 so 80*2.5=200g of butter.

Answer:

a) 80g of fish

b)200g of butter

Step-by-step explanation:

a) 240/6=40g per people

40*2=80

b)80/6=13 1/3g per people

13 1/3*15=200

Step-by-step explanation:

Answer:

Part A: Factor out the GCF. In this case, the GCF is 2y. So it looks like

2 x^3 * y+18xy-10 x^2 * y-90y=2y (x^3 - 5 x^2 + 9x-45)

Part B: The result from above will need to be factored by grouping.

Part C: If you switch the terms, the factoring will work out differently, but at the end, the factorization will be the same.

Answer:

1,000,000

Step-by-step explanation: Since there are 10 possible digits, we know that there is a 1/10 chance for any possible digit in any slot. So, since there are 6 slots we can do 1/10^6, or 1 in 1 million.

So, 720 ways are available if each digit can be repeated

Answer:

The relation is a linear function with the equation: y = -6/5x + 3/5

Step-by-step explanation:

                                            Question 5)

The given graph is a straight line.

We know that the graph of a linear function is a straight line that can be written in the form

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

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

The slope of the line can be determined by taking two points

(3, -3)

(-2, 3)

Finding the slope

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

[tex]\left(x_1,\:y_1\right)=\left(3,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-2,\:3\right)[/tex]

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

[tex]m=-\frac{6}{5}[/tex]

From the graph, the y-intercept can be obtained by setting x=0 and check the corresponding y-value of y.

or substituting m = -6/5 and (3, -3) in the slope-intercept form to determine y-intercept 'b'.

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

[tex]-3\:=-\frac{6}{5}\left(3\right)\:+\:b[/tex]

[tex]-\frac{18}{5}+b=-3[/tex]

[tex]b=\frac{3}{5}[/tex]

now substituting m = -6/5 and b = 3/5 in the slope-intercept form to determine the equation of the linear function

y=mx+b

y = -6/5x + 3/5

Therefore, the relation is a linear function with the equation: y = -6/5x + 3/5

Hello!

[tex]\large\boxed{c = 12.65}[/tex]

Use the Pythagorean Theorem to solve for the hypotenuse:

a² + b² = c²

Plug in the given values:

12² + 4² = c²

144 + 16 = c²

160 = c²

Take the square root of both sides:

c = √160

c ≈ 12.65.
