The correct answer is 15 months. If you take the base fee of $50 than add $55 multiplied by 15 you will get $825 add the $50 it equals $875 for the second part your base fee is $200 multiply $45 by 15 which is the month and you get $675 add the $200 base fee and it is $875. The answer to your question is 15 months. Hope I helped

what is cos of negative pi/3?
what is sin of negative pi/3?

Answers

pi/3 is equivalent to 60 degrees, as 2pi is equal to 360 degrees. cos(60) in a triangle yields 1/2, and sin(60) yields (3^(1/2))/2. Thus, -pi/3, or -60 degrees would be a fourth quadrant point on the unit circle and these values would be negative as well, at cos(-pi/3)=-1/2 and sin(-pi/3)=-(3^(1/2))/2 
Cosine is even function, so:

[tex]$\cos(-\frac{\pi}{3})=\cos(\frac{\pi}{3})=\frac{1}{2} [/tex]

and sine is odd function, so:

[tex]$\sin(-\frac{\pi}{3})=-\sin(\frac{\pi}{3})=-\frac{\sqrt{3}}{2} [/tex]

What is the measure of angle WZX?

Answers

I hate Time4Learning. I took that back in middle school.

Here's how these expressions work together. First, you need to remember WZY is a right angle (90 degrees). Now, keep that in mind when we add both equation.

3c + 2c + 2 - 7 = 90

5c - 5 = 90

5c - 5 + 5 = 90 + 5

5c = 95

5c/5 = 95/5

c = 19. Now, put 19 in the place of c and solve.

3(19) + 2 = 57 + 2 =

59 degrees.

The measurement of angle WZX is equal to 59 degrees, B.

5/16t=-9

Plz help me ASAP and show all of the steps that you did! PLEASE HELP!!! :) 10 POINTS!!!!!

Answers

I'm going to assume that the equation is [tex]\frac{5}{16}t = -9[/tex] where the 't' is not in the denominator

If that assumption is correct, then we do two things to solve for t. First, we multiply both sides by 16. This undoes the division of 16 on the left side

[tex]\frac{5}{16}t = -9[/tex]

[tex]16*\frac{5}{16}t = 16*(-9)[/tex]

[tex]5t = -144[/tex]

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

Then we divide both sides by 5 to undo the multiplication of 5 (note: 5t means 5*t or "5 times t")

[tex]5t = -144[/tex]

[tex]\frac{5t}{5} = \frac{-144}{5}[/tex]

[tex]t = -\frac{144}{5}[/tex]

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

So here's what all the steps look like:

[tex]\frac{5}{16}t = -9[/tex]

[tex]16*\frac{5}{16}t = 16*(-9)[/tex]

[tex]5t = -144[/tex]

[tex]\frac{5t}{5} = \frac{-144}{5}[/tex]

[tex]t = -\frac{144}{5}[/tex]

note: -144/5 converts to the decimal value of -28.8 so t = -144/5 is the same as t = -28.8

What is the perimeter of a square with an area of 144 square inches?

Answers

Hi!

Since we know a square has sides of equal length, and to find the area of a square you square one of the side lengths, find the square root of 144.

The square root of 144 is 12.

So the means each side length is 12.

A perimeter is the distance around the square, or all of the side lengths added together.

4 sides on a square, each length is 12...
12 x 4 = 48

The perimeter is 48

Hope this helps! :)

Answers

I think the answer would be d because you are trying to protect your home from getting struck by lightning.

Answer:  Option 'D' is correct.

What is the solution to the following system of linear equations?

{4x - y = -6
{x - 2y = -5

Please explain how you solved!

Answers

Final answer:

The solution to the system of linear equations is x = -1, y = 2

Explanation:

To solve the system of linear equations:
4x - y = -6
x - 2y = -5
We can use the method of substitution or elimination to find the solution.
Let's use the elimination method. We can multiply the second equation by 4 to make the coefficients of x in both equations the same.
4(x - 2y) = 4(-5)
4x - 8y = -20
Now, we can subtract the second equation from the first equation to eliminate x.
(4x - y) - (4x - 8y) = (-6) - (-20)
-y + 8y = 14
7y = 14
y = 2
Substituting y = 2 back into the first equation:
4x - 2 = -6
4x = -4
x = -1
The solution to the system of linear equations is x = -1, y = 2

What can be divided into 5 AND 8? 40!

How many times can 40 be divided into 5? 8 times!

How many times can 40 be divided into 8? 5 times!

So, you take that number and multiply it by the numerator (top number) and you get your new yet equivalent fraction.

3/5 turns into 24/40 & 5/8 turns into 25/40

So, our new question looks like this :

24/40 + 25/40

Since both of these fractions have the same denominator (bottom number), you can simply add the top numbers together! :)

24 + 25 = 49

So, our answer to 3/5 + 5/8 = 49/40

Turn this into a mixed number.

49/40 = 1 9/40

So, your FINAL ANSWER is 1 9/40

If a function f(x) is the temperature in degrees as a function of time in minutes. then the function f'(x) is

Answers

f'(x)  is the instantaneous change of temperature at  a specific time in minutes.

In the context of a function representing temperature over time, the derivative f'(x) indicates the rate of change of the temperature with respect to time.

If a function f(x) represents the temperature in degrees as a function of time in minutes, the function f'(x) represents the rate of change of temperature with respect to time. This implies that if you have the temperature reading from a thermometer at different times, f'(x) tells you how quickly the temperature is rising or falling at any given moment. The concept of the derivative as the rate of change applies to many types of functions beyond just temperature over time.

A moving company charges a $2,000 fee plus $100 per hour. Another moving company charges an $1,800 fee plus $150 per hour. How long is a job for which the two companies' costs are the same?

Answers

The costs of two moving companies are the same for a job that lasts 4 hours.

To find out how long a job must last for the two companies' costs to be the same, we need to set up an equation where both company costs are equal and solve for the time variable, which I will denote as 't' hours.

The first moving company's cost can be represented as:$2,000 + $100 x t.

The second moving company's cost can be represented as: $1,800 + $150 x t.

To find the time when both costs are the same, we set the two expressions equal to each other:

$2,000 + $100t = $1,800 + $150t

Now, we need to solve for 't' by subtracting $100t from both sides and subtracting $1,800 from both sides:

$200 = $50t

Divide both sides by $50 to isolate 't':

t = 4 hours

So, the two companies would have the same cost for a 4-hour job.

Write the equation of the line that is perpendicular to 5x+8y=16 and passes through (-5,7).

Answers

In order to do this problem, we should first put the equation in slope-intercept form, and then consider the relationship between the slopes of perpendicular lines. 
Slope Intercept form (y=mx + b), m=slope, b=y-intercept
5x + 8y = 16         Subtract 5x from both sides
8y=-5x + 16          Divide both sides by 8
y= (-5/8)x  + 2

This is our line in slope-intercept form. What will the slope be of a line that is perpendicular to this one? It will be the opposite inverse of the slope of our equation. The opposite inverse means flipping the numerator and denominator, and multiplying by negative one.
Our slope = -5/8, so the opposite inverse is 8/5.

The slope of our perpendicular line will be 8/5
In slope intercept form, our line will be 
y=(8/5)x + b
We know it passes through the point (-5,7), so we can plug in -5 for x and 7 for y in order to find b:
7 = (8/5) * -5 + b
7 = 8 *-1 + b        Add 8 to both sides
15 = b
Plugging in b, we can get our general function in slope-intercept form:

y= (8/5)x + 15
