Find the value of x in the triangle shown below.
Alekssandra [29.7K]

Answer:

102 degrees.

Step-by-step explanation:

Because the 3.3's are congruent (the same), this triangle is isosceles.

A property of isosceles means that the two angles are congruent.

39+39= 78

This means that the last angle must be 180-78.

Students in a zoology class took a final exam. They took equivalent forms of the exam at monthly intervals thereafter. After t​
juin [17]

Answer:

a. 73; b. 48.9; c. 2; d. 33.8; e. 73

Step-by-step explanation:

Assume the function was

S(t)= 73 - 15 ln(t + 1), t  ≥ 0

a. Average score at t = 0

S(0) = 73 - 15 ln(0 + 1) = 73 - 15 ln(1) = 73 - 15(0) =73 - 0 = 73

b. Average score at t = 4

S(4) = 73 - 15 ln(4 + 1) = 73 - 15 ln(5) = 73 - 15(1.61) =73 - 24.14 = 48.9

c. Average score at t =24

S(24) = 73 - 15 ln(24 + 1) = 73 - 15 ln(25) = 73 - 15(3.22) =73 - 48.28 = 24.7

d. Percent of answers retained

At t = 0. the students retained 73 % of the answers.

At t = 24, they retained 24.7 % of the answers.

\text{Percent retention} = \dfrac{\text{24.7}}{\text{73}} \times 100 \, \% = \text{33.8 \%}\\\\\text{The students retained $\large \boxed{\mathbf{33.8 \, \%}}$ of their original knowledge after two years.}

e. Maximum of the function

The maximum of the function is at t= 0.

Max = 73 %

The graph below shows your knowledge decay curve. Knowledge decays rapidly at first but slows as time goes on.

In a company 70% of the workers are men. If 1590 people work for the company who arent men, how many workers are there in all?
meriva

Answer:

5300

Step-by-step explanation:

1590 people are not men so they are women

so

\frac{100 - 70}{100 }  =  \frac{1590}{x}  \\  \\  \frac{3}{10}  =  \frac{1590}{x}  \\  \\ x = 5300 \: totoal \: workers
