Answer:

15 miles

Step-by-step explanation:

If there are 2.5 inches and 1 inch is 6 miles, then just multiply 6 by 2.5 to get 15

6*2.5=15

Answer:

Yes,they are in proportion

Step-by-step explanation:

We are told that 150 litres of water flows through a pipe in 6 minutes.

Thus means that the rate of flow = 150/6 = 25 litres/minutes

Now, we are also told that through the same pipe, 200 litres of water flows in 8 minutes. This means that the rate of flow = 200/8 = 25 litres/minutes

Now, the rate of flow is both instances is the same. Thus, we can say they are in proportion because;

Proportion of quantity in both instances = 200/150 = 4/3.

while that of time = 8/6 = 4/3

They have the same proportion

Rate of change is 2.

Y = mx + b (m is rate of change)

Answer:

[tex](-2,6)[/tex]

Step-by-step explanation:

Given

[tex]Elena = (10,-4)[/tex]

[tex]Midpoint = (4,1)[/tex]

Required

Determine the coordinates of Naya's

Midpoint is calculated as:

[tex]M(x,y) = \frac{1}{2}(x_1+x_2,y_1+y_2)[/tex]

In this case:

[tex](x_1,y_1) = (10,-4)[/tex]

[tex](x,y) = (4,1)[/tex]

So, we have:

[tex](4,1) = \frac{1}{2}(10+x_2,-4+y_2)[/tex]

Multiply through by 2

[tex]2 * (4,1) = \frac{1}{2}(10+x_2,-4+y_2) * 2[/tex]

[tex](8,2) = (10+x_2,-4+y_2)[/tex]

By comparison:

[tex]8 = 10 + x_2[/tex]

[tex]2 = -4 + y_2[/tex]

So:

[tex]8 = 10 + x_2[/tex]

[tex]x_2 = 8 - 10[/tex]

[tex]x_2 = -2[/tex]

[tex]2 = -4 + y_2[/tex]

[tex]y_2 =2+4[/tex]

[tex]y_2 =6[/tex]

So, the coordinate is: [tex](-2,6)[/tex]

Answer:

LCM = 75

GCF = 25

Step-by-step explanation:

25 = 5 x 5

75 = 3 x 5 x 5

LCM = 3 x 5 x 5 = 75

GCF = 5 x 5 = 25

Hope that helps!

Answer: The LCM of 25 & 75 is 75, and the GCF of them is 25

Step-by-step explanation: hope it helps :)

Answer:

[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]

[tex]7.1034 * 10^3 = 7103.4[/tex]

Step-by-step explanation:

Solving (a):

[tex]0.0005[/tex]

Standard form is represented as:

[tex]a * 10^n[/tex] where [tex]1 \le a \le 10[/tex]

Move the decimal point to 5 and count the number of times the decimal point is moved forward (forward represents negative).

So:

[tex]a = 5[/tex]

[tex]n = -4[/tex]

Hence:

[tex]0.0005[/tex] [tex]= 5 * 10^{-4[/tex]

Solving (b):

[tex]7.1034 * 10^3[/tex]

Express [tex]10^3[/tex] as [tex]1000[/tex]

This gives:

[tex]7.1034 * 10^3 = 7.1034 * 1000[/tex]

[tex]7.1034 * 10^3 = 7103.4[/tex]

Step-by-step explanation:

I dont think those are wuestiojs to be answered. Probably questions on how the equation is solved

The expressions  3x² - 7y, 2 - 8y, 4x² - 9  are polynomilas.

A polynomial is an algebraic expression of degree n where n belongs to whole numbers.

A polynomial of degree n can be written as a₀xⁿ + a₁xⁿ⁻¹ + a₂xⁿ⁻² + ... + aₙ.

Given, are 4 polynomials 3x² - 7y it is a polynomial because it has powers that are in whole numbers and it is of degree 2 in variables x and y.

2 - 8y is also a polynomial as the degree of y is 1 and it is a whole number.

3x⁻² + y is not a polynomial as the degree of x is - 2 and it is not a whole number.

4x² - 9 is also a polynomial as it has a degree of 2 a whole number.

Answer:

28.9 Dollars/Hour

Step-by-step explanation:

Rate of Change is the slope, is it is rise over run.

it goes from 289 to 578, so the change is 289.

it goes from 20 to 10, so the change is 10.

289/10 is 2.89.

Answer:

m = 1/2

Step-by-step explanation:

The given equation of line is :

2x – 4y = 9 ..(1)

We need to find the slope of the line. The general equation of a line is given by :

y = mx + c ..(2)

Where

m is the slope of line

Equation (1) can be rearranged as follow :

-4y = 9-2x

4y = -9+2x

or

4y = 2x-9

Divide both sides by 4.

[tex]\dfrac{4y}{4} = \dfrac{2x}{4}-\dfrac{9}{4}\\\\y=\dfrac{1}{2}x+(\dfrac{-9}{4})[/tex] ..(3)

Now comparing equation (2) and (3) we get :

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

So, the slope of the line is 1/2.
