Which rates are unit rates? Check all the apply.

Mathematics
1 answer:
GalinKa [24]3 years ago
5 0

Answer:

  • 9 students : 1 table
  • 87 pebbles per aquarium
  • 10 slices for each child

Step-by-step explanation:

A "unit" rate is one that has a denominator of 1 unit.

12 apples : 3 baskets has a denominator of 3, so is not a unit rate. It could be made into a unit rate of 4 apples : 1 basket by dividing the numbers by 3.

Similarly, $5 for 4 muffins has a denominator of 4, so is not a unit rate. The equivalent unit rate is ($5/4) per muffin, or $1.25 per muffin.

All of the other offered choices are unit rates. (See list above.)

Find the slope:

(-4 - (-2))/(-3 - (-1))

Which type of transformation is described by (x, y)<br> -&gt;<br> + (x + 3, y — 2)?
creativ13 [48]

Answer:

(x, y) → (x+3, y-2) means Translation 3 units left and 2 units down.

Step-by-step explanation:

Given the rule of transformation:

(x, y) → (x+3, y-2)

If we move horizontally 3 units to the right, 3 is added to the x-coordinate of any given point, and then 2 units down.

In other words,

(x, y) → (x+3, y-2) means Translation 3 units left and 2 units down.

For example,

Let say if we have the point A(4, 5)

Using the translation rule:

(x, y) → (x+3, y-2)

A(4, 5) → A'(4 + 3, 5 - 2) → A'(7, 3)

Therefore, the new position of A(4, 5) after translating 3 units left and 2 units down would be: A'(7, 3)
