Answer:
Step-by-step explanation:
Amount deducted for Medicare = $725
Amount deducted for state income tax = $3000
Amount deducted for Social security = $3100
To find: Total amount deducted from Alton's pay for FICA last year
Solution:
Total amount deducted from Alton's pay for FICA last year = Amount deducted for Medicare + Amount deducted for state income tax + Amount deducted for Social security =
On adding 725 and 3000, we get
On adding 3725 and 3100, we get
So, amount deducted =
The graph that would best fit an exponential function is the fourth graph.
Answer:
The maximum area of one square plot is 144
Step-by-step explanation:
Start by looking at what are the greater common factor of both provided dimensions (840 and 396) to find what the numbers are they both can be divided by evenly:
therefore, both numbers can be divided by
Which then gives:
Then, one can divide the longest side (840 m) into 70 sections of 12 meters each, and the shortest side of the piece of land (396 m) into 33 sections of 12 meters each.
Then we can have a total of 33 * 70 = 2310 smaller lots of 12 m by 12 m
That is smaller plots of a total area 144 square meters
