Illusion [34]3 years ago
7 0

A "unit rate" has a denominator of 1. That will often simplify any subsequent math operations.

_____

The choice of the form of a ratio should be made based on what you need to do with it. Sometimes, a denominator other than 1 is appropriate to follow-on operations you may need to perform.

Part 2. Identify whether the red figure is a translation or rotation of the black figure​
Iteru [2.4K]

Answer:

So a rotation means that it will be rotated, a translation means that it will be drawn the same thing without rotation but in a different place. So we can easily see here that the red figure is the exact same thing as the black figure so its a translation

solmaris [256]

Answer:

the correct answer is 24 quarters

Step-by-step explanation:

Since Ben parks for 3 hours and one hours costs $2

Therefore 3 hours = $2.00 × 3 hours = $6.00

Next, note that 1 quarter = 25 cents (same as One-quarter of a dollar)

∴ 1 quarter = 1/4 dollar

= 1 quarter = 0.25 dollars.

$0.25 = 1 quarter

∴ $6 = (1/0.25) × 6 = (6 ÷ 0.25) = 24 quarters

Make a table of values for the following equation:
mars1129 [50]

Answer:

Step-by-step explanation:

We choose arbitrary values for x and in each case calculate y = 2x + 5.

If x = 0, y = 5; if x = 3, y = 11, and so on.  

How?  when x = 3, y = 2(3) + 5 = 6 + 5 = 11.

The table, with rows and columns suitable to this problem, would look like:

x  y

0  5

3  11

10 25

and so on

the length of a rectangle is twice it's width. if the perimeter of the rectangle is 48 cm, find it's length and width.
Vilka [71]

Let L represent the length of the rectangle.

Let W represent the length of the rectangle.

We know that the perimeter of the rectangle is 48cm, which is equal to 2(L + W).

Therefore, L + W = 24cm.

We also know that L = 2W.

Hence, Length = 16cm and Width = 8cm.
