KatRina [158]4 years ago

Answer:

$65/hour

Step-by-step explanation:

Let C(h) represent the total amount payable to the plumber.  Then:

C(h) = $75 + (rate)(2 hr) = $205.  Solve for the "fixed hourly rate."

Subtracting $75 from both sides, we get:

(rate)(2 hr) = $130.

Dividing both sides by (2 hr) results in (rate) = $65/hour

Need assistance on some geometry
lukranit [14]

Answer:

So I can't actually put a picture in, put heres the easiest way to understand this. If it says y-1, take the coordinates for y, and subtract 1. do that to all of them, not just 1. For example, R is 4,1. To translate it, you would take the y coordinate (1) and subtract 1. We know to do this because it shows translation x,y)->(x,y-1). Thus, the new point would be 4,0. apply this to all of the points.

If sin θ = 3 over 7 and tan θ < 0, what is the value of cos θ?
AnnZ [28]
if\ \sin\Theta \ \textgreater \  0\ and\ \tan\Theta \ \textless \  0\ then\ \Theta\in\underbrace{(90^o;\ 180^o)}_{\left(\dfrac{\pi}{2};\ \pi\right)}\\\\therefore\ \cos\Theta \ \textless \  0.

\text{Use:}\ \sin^2x+\cos^2x=1\\\\\left(\dfrac{3}{7}\right)^2+\cos^2\Theta=1\\\\\dfrac{9}{49}+\cos^2\Theta=1\ \ \ |-\dfrac{9}{49}\\\\\cos^2\Theta=\dfrac{40}{49}\to\cos\Theta=-\sqrt{\dfrac{40}{49}}\\\\\cos\Theta=-\dfrac{\sqrt{40}}{\sqrt{49}}\\\\\cos\Theta=-\dfrac{\sqrt{4\cdot10}}{7}\\\\\boxed{\cos\Theta=-\dfrac{2\sqrt{10}}{7}}

I need to remember how to solve this problem
Tamiku [17]

You have to move all terms involving the variable on one side, and all constant terms on the other side.

To move a term from a side to the other, you have to change its side.

So, for example, if you move 4x from left to right, it will become -4x (you're actually subtracting 4x from both sides):

1 = -5+7x-4x = -5+3x

Similarly, add 5 to both side to get

1+5 = 3x \iff 3x = 6

Finally, divide both sides by 3:

x = 2
