For the given angle 0, identify the reference angle, _
ankoles [38]

Answer:

π\6

Step-by-step explanation:

The reference angle is the smallest angle measured from the terminal side of the angle (where the angle ends) to the x axis. The reference angle is an acute angle (i.e less than 90° or π/2)

For O = 11π/6 = 1.833π

1.833π is in the fourth quadrant between 3π/2 radians and 2π radians. Since it is in the fourth quadrant, the reference angle is given as:

reference angle = 2π - 11π/6 = π\6

What is m∠D? Enter your answer in the box.
Alex73 [517]

Answer:

D = 32

Step-by-step explanation:

A+ B + E = 180 since they form a triangle

14+ 45 + E = 180

E = 180 -14-45

E =121

E on either triangle is the same since they are vertical angles

C+D+E = 180 since they form a triangle

27+ D + 121 = 180

D = 180-121-27

D =32

</span>7 times the sum of a squared and b is given by
</span><span>7(a^2+b)
while 4 times the sum of a squared and b is given by
</span>4(a^2+b)

Therefore, <span>7 times the sum of a squared and b minus 4 times the sum of a squared and b is given by

In​ 2006, the population of the country was 30.4 million. This represented an increase in population of 7.6 % since 2001. What w
Molodets [167]

Answer:

28.25 million

Step-by-step explanation:

Population of the country:

  • in 2001 - x million
  • in 2006 - 30.4 million

Population of the country as percent:

  • in 2001 - 100%
  • in 2006 - 100% + 7.6% = 107.6%

Write a proportion:

\dfrac{x}{30.4}=\dfrac{100}{107.6}

Cross multiply:

107.6\cdot x=30.4\cdot 100

Divide by 107.6:

x=\dfrac{30.4\cdot 100}{107.6}=\dfrac{3,040}{107.6}\approx 28.25

jeds market has a total of 26 employees. Each full time employee makes $275/ week, and each part-time employee makes $140/ week.
I am Lyosha [343]

Answer:

f=17\\p=9\\

Step-by-step explanation:

Let

f= Full-time\\p=Part-time

Full time rates-$275, Part-time rates-$140

The problem can be expressed as:

f+p=26...eqtn1\\275f+140p=5935....eqtn2\\

Express eqtn1 in terms of f,f=26-p

Substitute f value in eqtn 2.

=>275(26-p)+140p=5935\\7150-275p+140p=5935\\1215=135p\\p=9\\f=26-9=17\\

Therefore,  jeds has 17 fulltime and 9 parttime employees.
