Which of the following is NOT true about unit rates? 1. A unit rate relates a quantity to

2. Unit rates can be used to compare two rates.

3. Any rate is equivalent to its unit rate.

4. A unit rate always relates quantities with the same units.

1,2,3,4 is the correct option

4

Step-by-step explanation:

For different problems or situations, the unit might be different (dollars, miles, crocodiles, etc). However, a unit rate can be used to compare two rates and is always equal to any other rate you can write for the same problem. (since 4 is clearly false, I assume 1 is correct, even though it seems to have been cut off).

i am sure it will be 90 degrees.

step-by-step explanation:

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
