A traveler is walking on a moving walkway in a n airport. The traveler must walk back on the walkway to get a bag he forgot. The traveler's ground speed is 2 ft/s against the walkway and 8 ft/s with the walkway. What is the traveler's speed off the walkway? What is the speed of the moving walkway?

Answer:

(x+8)(x+5)

Step-by-step explanation:

Since we know x2 is equivalent to x times x we can automatically start by filling in the first two spaces with x. Then since we know that we're going to need two numbers that equal forty since it's part of the equation we can get two number that will also add up to 13x which is 8 and 5. We then get (x+8)(x+5). (Sorry lol this question is kind hard to explain over the computer.)

Answer:

(n - 8n)(m+8n)

Step-by-step explanation:

x² - y² = (x - y)(x + y)

In this situation, the "x" = m and the "y" = 8n

So,

m² - 64n² = (n - 8n)(m+8n)

Answer:

(m - 8n)(m + 8n)

Step-by-step explanation:

m² - 64n² ← is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

m² - 64n²

= m² - (8n)²

= (m - 8n)(m + 8n)

Step-by-step explanation:

Let amount of money = C

If the number of chocolate bars sold = x

Let cost per chocolate bar = p, since cost per bar isn't stated

Amount of money that will be collected :

C(x) = P * x

The dependent variable is the Amount of money that will be collected as the amount of money depends on the number of chockate bars sold

The number of chocolate bars sold us the independent variable as it dictates the amout of money to be collected, hence it is the predictor variable.

Answer:658.73

Step-by-step explanation:

6.25 percent of 619.98 is $34.74875

we round $34.74875 to $34.75

then we add

619.98 + 34.75 = 658.73

Answer:

casey has the faster rate

Step-by-step explanation:

first multiply jessicas race distance and time by 2

30 * 2

= 60    

5 * 2

= 10

we did that so both jessicas time and caseys time was the same, making it easier to solve ( also by this point we already know who has the faster rate )

now we are going to divide both of their times and distances by 5

casey

10/5

= 2

45/5

= 9

jessica

10/5

= 2

60/5

12

the step is to divide their times/distances once again but this time by 2

casey

2/1

= 1

9/2

= 4.5

jessica

2/1

= 1

12/2

= 6

and our answer is 4.5 or casey !

4.5 > 6

hope this helps you! :)

Answer:

8

Step-by-step explanation:

First we subtract 33 by 9 which equals 24. Then we divide 24 by 3 which equals 8.

To check your answer, multiply 8 by 3 then add 9.

b = 8

a = 1

using the formula given

x = -8/2

x = -4

Step-by-step explanation:

The only system of equation (A) has a y-value of 0.

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

To find the solution with a y-value of 0, we need to substitute y=0 in each equation of the system and solve for x.

(A) x + 2y = -1

x + 2(0) = -1

x = -1

y = 3x + 3

y = 3(-1) + 3

y = 0

The solution to system A has a y-value of 0.

(B) 3x - y = 2

3x - 0 = 2

x = 2/3

x + 2y = -1

(2/3) + 2y = -1

2y = -1 - (2/3)

2y = -5/3

y = -5/6

The solution to system B does not have a y-value of 0.

(C) y = 3x + 3

y = 3x + 3 implies that y cannot be 0, so this system cannot have a solution with a y-value of 0.

(D) 2x + 3y = 0

2x + 3(0) = 0

2x = 0

x = 0

x + 2y = -1

0 + 2y = -1

y = -1/2

The solution to system D does not have a y-value of 0.

Therefore, the solution to system A has a y-value of 0.

The origin is the middle of the plot, which is represented by the coordinates (0,0)

So, yoy would click on the middle where it says 0.

Answer: 0.75n+1.75 ≤ 20 because you have to have the number of additional miles with the cost of $0.75 per mile but then you have to add the original first mile with a cost of $1.75. It has to be less than or equal to because you only have $20 to spend you can't spend more than that you have to spend that amount or less.

[tex]\frac{1}{\sqrt{3} }[/tex]

Step-by-step explanation:

A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.

In the unit circle below, we can see that the line touches the unit circle at point [tex](\frac{\sqrt{3} }{2} ,\frac{1}{2})[/tex], therefore to find the tangent of theta, we use the formula:

[tex]tan\theta = \frac{y}{x} \\\\tan\theta=\frac{\frac{1}{2} }{\frac{\sqrt{3} }{2} } =\frac{1}{2}*\frac{2}{\sqrt{3} } \\\\tan\theta=\frac{1}{\sqrt{3} }[/tex]

Answer:

C. $4.50

Step-by-step explanation:

hello, there.

1) 2p + 3c = 17.50

2) 5p + 2c = 19.00

:

Solve equation 1 for p

:

p = (17.50 - 3c) / 2

:

Substitute for p in second equation

:

(5(17.50 - 3c) / 2) + 2c = 19.00

:

Multiply both sides of = by 2

:

(5(17.50 - 3c)) + 4c = 38.00

:

87.50 - 15c + 4c = 38.00

:

-11c = -49.50

:

c = 4.50

---------

Cashews are $4.50 per pound

--------------

:have a great day.

Answer:

C

Step-by-step explanation:

Let p represent the cost for one pound of peanuts and let c represent the cost for one pound of cashews.

Two pounds of peanuts and three pounds of cashews cost $17.50. So:

[tex]2p+3c=17.5[/tex]

Five pounds of peanuts and two pounds of cashews cost $19.00. So:

[tex]5p+2c=19[/tex]

This yields a system of equations.

We can solve this using elimination. We can multiply the first equation by -5, and the second by 2. Therefore:

[tex]-5(2p+3c)=-5(17.5)[/tex]

Multiply:

[tex]-10p-15c=-87.5[/tex]

And:

[tex]2(5p+2c)=2(19)[/tex]

Multiply:

[tex]10p+4c=38[/tex]

Now, we can add the two equations together:

[tex](-10p-15c)+(10p+4c)=(-87.5+38)[/tex]

Combine like terms:

[tex]-11c=-49.5[/tex]

Therefore:

[tex]c=4.5[/tex]

So, a pound of cashews costs $4.50.

Our answer is C.

Notes:

To solve for the cost for peanuts, we can use the first (or second equation) again:

[tex]2p+3c=17.5[/tex]

Substitute:

[tex]2p+3(4.5)=17.5[/tex]

Solve for p:

[tex]2p+13.5=17.5\Rightarrow 2p=4\Rightarrow p=2[/tex]

So, a pound of peanutes cost $2.00.
