add all known angles:
90 + 107 + 144 + 138 = 479
the interior angles of a 5 sided polygon need to equal 540
540 - 479 = 61
x = 61 degrees
1) function 2) not a function
the first one is a function because its y values are the same number (3), which means it is a horizontal line and horizontal lines are functions.
the second one is not a function because the coordinates cannot have different inputs but different outputs. each input must have only one output.
the coordinates for the second one are:
(2,5); (1,1); (1,2); (3,2)
and <u>a function cannot have two same x-coordinates</u>. it must pass the vertical line test which is a way to tell if something is a function or not. since the second graph does not pass the vertical line test, it is not a function
hope this helps :)
Answer:
$697
Step-by-step explanation:
Given that :
Weekly earning = $375 plus 7% commission on sales
Earning if she sold $4600 worth of merchandise
Commision on sales = 7% of 4600
Commission = 0.07 * 4600
Commission on sales = $322
Total earning = $375 + $322
Total earning = $697
Answer: 8 is the answer
Step-by-step explanation:
Divide 27 by 60, then multiply by 100:
27 /60 = 0.45
0.45 x 100 = 45%
