Answer:

It Depends

Step-by-step explanation:

If the image is the scale, the answer is 1/3, since its width of 3 is 1/3 the width of the actual book.

If the book is the scale, the answer is 3, since its width of 9 is 3 times the width of the image.

If one pound of cement cost r dollars, what is the price of z pounds in cents
slavikrds [6]

Answer:

100rz cents.

Step-by-step explanation:

The price of cement with respect to its weight is proportional.

So, we can write p ∝ w  

where p is the price in dollars and w is the weight of the cement in pounds.

⇒ p = kw  ............... (1) {Where, k = proportionality constant}

Given that, one pound of cement cost r dollars.

So, from equation (1), we can write

r = k(1)

⇒ k = r

So, the equation becomes p = rw .............. (2)

Now, for w = z pounds, the price will be p = rz dollars. {From equation (2)}

Therefore, the price of z pounds in cents will be 100rz cents. (Answer)

What is the length of segment AB? (1 point) Coordinate grid shown from negative 8 to positive 8 on both x axis and y axis at int
Marina CMI [18]

Answer:

<h2>The distance between points A and B is 8.5 units, approximately.</h2>

Step-by-step explanation:

In the image attached you can observe a representation of the problem.

We have to find the distance between points A and B, which have coordinates (6,0) and (0,6), respectively.

The definition of distance between to given points is

d=\sqrt{(y_{2} -y_{1} )^{2} +(x_{2} -x_{1})^{2} }

Using points A and B, the distance between is

d_{AB}=\sqrt{(6-0)^{2} +(0-6)^{2} }  =\sqrt{36+36}=\sqrt{72} \\ d_{AB} \approx 8.5

Therefore, the distance between points A and B is 8.5 units, approximately.
