The order of operations is : 1.) parenthesis. 2.) exponents. 3.) multiplication 4.) division 5.) addition 6.) subtraction. an easy way to remember this is PEMDAS. or Please Excuse My Dear Aunt Sally. so for this equation it would be 7+2 =9 soo 8(9)+6(8-7) which would then be 8(9)+6(1) then 72+6= 78 < is the final answer.

8(7+2)+6(8−7)

=(8)(9)+6(8−7)

=72+6(8−7)

=72+(6)(1)

=72+6

The table below shows the typical hours worked by employees at a company. A new employee is offered an annual salary of $37,000.

Mademuasel [1]

Answer:

Salaried pay is preferable for a new employee

Step-by-step explanation:

<u>As per table, hours worked per week:</u>

0+ 8.5+ 9.5+ 7.5+ 8+ 8.5+ 4 = 46

<u>Employee gets paid for 46 hours per week:</u>

$40*14 + (46- 40)*$21 = $686

<u>Average yearly salary would be:</u>

$686/7*365 = $35770

<u>Comparing with annual salary, we see:</u>

$37000 > $35770

As we see, hourly employees get paid less, so the new employee should choose annual salary option

Show that the triangles are similar by comparing the ratios of the corresponding sides. Simplify your answer completely in order

kirill [66]

Answer/Step-by-step explanation:

AC = 1.2

AB = 4

BC = 2.6

DF = 3

DE = 10

EF = 6.5

Thus:

$\frac{DE}{AB} = \frac{10}{4} = \frac{5}{2}$

$\frac{DF}{AC} = \frac{3}{1.2} = \frac{3*10}{1.2*10} = \frac{30}{12} = \frac{5}{2}$

$\frac{EF}{BC} = \frac{6.5}{2.6} = \frac{6.5*10}{2.6*10} = \frac{65}{26} = \frac{5}{2}$

The ratio of their corresponding sides are all equal to ⁵/2. Therefore, both triangles are similar.
