Which table shows a proportional relationship between weight and price?
Lera25 [3.4K]

I believe it will be C- 1kg/0.25 because 2.00÷0.25 will give you 8. It should be the same for 8÷1 which will give you 8 also. That means it is porportional. I hope that helps you.

Parallelogram WXYZ. <br><br> WX = 13x + 15<br> YZ = 19x - 9<br><br> Find the values of x and y.
sweet-ann [11.9K]

Answer:

Step-by-step

sum of the adjacent angles of parallelogram is supplementary.

Therefore,

Q + R = 180°

4y+7 + 10y-37 = 180°

14y - 30° = 180°

14y = 210°

y = 210°/14

y = 15°

Could not found X in the question.

What is this limit equal to?
Nadya [2.5K]

Since the cotangent function is defined as

\cot(x) = \dfrac{\cos(x)}{\sin(x)}

we have that the cotangent equals zero at \frac{\pi}{2}, because we have

\cot\left(\dfrac{\pi}{2}\right) = \dfrac{\cos\left(\frac{\pi}{2}\right)}{\sin\left(\frac{\pi}{2}\right)} = \dfrac{0}{1} =0

So, the limit simply becomes

\dfrac{\pi}{2}\cdot 0 = 0

Solve for x? I'm confused
bezimeni [28]
180-145 will give you your answer cause when its a triangle they all = 180
so you add 80 + 65 = 145 
so 180-145
