Answer:

<em>412 adults </em>

Step-by-step explanation:

Let the number of adults be x

Let the number of children be y

If a total of 1,236 people attended the concert, then;

x + y = 1236 .....1

If there were twice as many adults as children who attended the concert, then;

y = 2x

Substitute y = 2x into 1

x + 2x = 1236

3x= 1236

x = 1236/3

x = 412

<em>Hence 412 adults attended the concert.</em>

Find the exact value of tan A in simplest radical form.
spin [16.1K]

Answer:

tan(A) = \frac{2\sqrt{15}}{11}

Step-by-step explanation:

Given:

Right ∆ABC

AB = 61

BC = 60

AC = 11

Required:

Value of tan A in radical form

SOLUTION:

tan(A) = \frac{opposite}{adjacent}

Opposite = 60

Adjacent = 11

tan(A) = \frac{60}{11}

tan(A) = \frac{\sqrt{4*15}}{11}

tan(A) = \frac{2\sqrt{15}}{11}

A survey asked people of different ages whether they get their news by reading the paper. What is the probability that a person
Bingel [31]

C. 60%

The probability that a person surveyed is 40 or older and gets the news by reading the paper is 60%.

Step-by-step explanation:

In our case, we have to find the probability of a person getting their news by reading the paper. But we are given with a condition that the person must be 40 or older.

The survey is conducted among 80 people.

Number of people aged 40 or older = 40

No of people aged 40 or older and read paper = 24

Probability formula is the ratio of number of favorable outcomes to the total number of possible outcomes.

Probability of a person aged 40 or older reads a paper =

(No. of People aged 40 or older and read paper)/(No. of people aged 40 or older)

= 24/40

= 0.6

= 60%

x=13

Step-by-step explanation:

Supplementary angles add to 180 degrees

x+167 = 180

Subtract 167 from each side

x+167-167= 180-167

x = 13

Identify the domain of the exponential function shown in the following graph. Explain how you know.
Dmitriy789 [7]

Answer:

The domain of the function is R i.e. any real value.

Step-by-step explanation:

The given figure is a graph on the coordinate plane of the function y = 10^{x}

Now, the domain of a function means that the values of x (Independent variable) for which the function is valid i.e. the y values are real.

It is clear from the equation given above that for any real value of x there will be a real corresponding value of y.

Therefore, the domain of the function is R i.e. any real value. (Answer)
