Answer:
C. 33 square feet.
Step-by-step explanation:
to get the area of irregular polygon.
divide the area into two parts (see attached image)
total area = A1 + A2
where A = 1/2 base x height
total area = ( 1/2 * 6 * 8) + (1/2 * 6 * 3)
total area = 24 + 9
total area = 33 square feet.
therefore the answer is C. 33 square feet.
ANSWER
to the nearest thousandth.
EXPLANATION
The given irrational number is
We use the calculator to evaluate this to obtain,
To round to the nearest thousandth means we are rounding to 3 decimal places.
The third decimal place is 5.
The next number is 5 so we round up.
To find which ratio is higher, we can first convert the ratios into fractions (that makes it easier, at least for me) and then simplify the fractions and see which one is greater.
Since ratios are basically division, 15:20 = , and
12:16 =
Now we simplify these fractions. 15 and 20 have a GCF of 5, so taking out the common number gives us the simplified fraction of .
12 and 16 have a GCF of 4, so taking out the common number gives us the simplified fraction of . Since
=
, these ratios are the same.
