Answer:
46
Step-by-step explanation:
The complete square starting with 
would be 
, since the square would be

So,
Normally a unit rate will be x per 1y. Example: 60 miles/1hr.
Therefore, the option with the denominator as 1 would be the unit rate.
The correct option is C.
Answer:
DCB = 84
Step-by-step explanation:
Here, we want to calculate the value of the angle
To do this, we use an important parallelogram angle property
The adjacent sides are supplementary, meaning they add up to 180
We have this as;
180-96 = 84 degrees
Answer:
The easiest approach is to realise that one hour is 3 times longer than 20 minutes. The longer the time, the more they will pave.
215 of a mile, in 20 minutes, how much in 60 minutes?#
They will pave 3 times more.
215×31=615 of a mile
615=25 of a mile
You could also use the 'unitary method' where you find out how much they pave in ONE minute (divide by 20) and them multiply by 60 to find how much in one hour.
Look at what happens:
215÷20×60
=215×120×603
=215×3 ← exactly the same maths.
=25
