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.

The length of a rectangle is twice its width. if the perimeter of the rectangle is 54 ft , find its length and width.

Let w be the width.

6w=54.
w=9
So length equals twice that...I think you can solve that on your own. xD

What is the area of a triangle whose vertices are
R(−4, 2),S(1, 2), and T(−5, −4)?
 
Enter your answer in the box

Answers

ANSWER

15 square units.

EXPLANATION

This triangle has one of its height(altitudes) falling outside the triangle.

We determine the base using absolute value method. This is because the coordinates of [tex]R(-4,2)[/tex] and [tex]S(1,2)[/tex] tell us that this line is horizontal. The y-values are constant.

Therefore [tex]|RS|=|1--4|[/tex]

[tex]\Rightarrow |RS|=|1+4|[/tex]

[tex]\Rightarrow |RS|=|5|[/tex]

[tex]\Rightarrow |RS|=5[/tex]

Also

The triangle is bounded between [tex]y=2[/tex] and [tex]y=-4[/tex].

Therefore the vertical height of interest,

[tex]|RT|=|-4-2|[/tex]

[tex]|RT|=|-6|[/tex]

[tex]|RT|=6[/tex]

We can now find the area using the formula

[tex]Area=\frac{1}{2}base\times height[/tex]

[tex]Area=\frac{1}{2}\times6 \times 5[/tex]

[tex]Area=3 \times 5[/tex]

[tex]Area=15[/tex] square units

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

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 are the solutions to x2 8x 7 = 0? x = –8 and x = –7 x = –7 and x = –1 x = 1 and x = 7 x = 7 and x = 8?

Answers

We want to solve
x² + 8x + 7 = 0

Factorize the left side.
x² + 8x + 7 = (x + 1)(x + 7)

Therefore
(x + 1)(x + 7) = 0
When (x + 1) = 0, obtain x = -1.
When (x + 7) = 0, obtain x = -7.

The solutions are x = -1 and x = -7

Answer: x = -7  and x = -1.


The correct solutions to the given equation are x = 1 and x = 7.

The solutions to the equation x² - 8x + 7 = 0 are x = 1 and x = 7.

To find these solutions, we can factor the quadratic equation by finding two numbers that multiply to 7 (the constant term) and add up to -8 (the coefficient of the x term).

Therefore, the correct solutions to the given equation are x = 1 and x = 7.

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 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
