Choose the best answers to complete the statements below. every employee works 7 hours per day. every employee works 5 days per week. every employee works 49 weeks per year. every employee works days per year every employee works hours per year

We have the following affirmations:

 Every employee works 7 hours per day.

 Every employee works 5 days per week.

 Every employee works 49 weeks per year.

 We now seek to complete the last affirmations.

 To do this, we must make use of the three statements given.

 We have then:

 Every employee works days per year:

 For this case we can make the following rule of three:

 5 days ---> 1 week

 X > 49 weeks

 Clearing x we have:

 X = (49/1) * (5)

 X = 245 days

 Then, we have:

 Every employee works hours per year:

 For this case we can make the following rule of three:

 7 hours ---> 1 day

 X > 245 days

 Clearing x we have:

 X = (245/1) * (7)

 X = 1715 hours

 Every employee works 245 days per year

 Every employee works 1715 hours per year

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.

let x and 400 - x be the two numbers.  

==> 0.80x + 0.85(400 - x) = 400 - 68 from the statement of the problem.  

< ==> 0.80x + 0.85(400 - x) = 400 - 68  

==> 340 - 0.05x = 332  

< ==> -0.05x = -8 ==> x = 160, the first number ==> 400 - x = 240, the second number.
