Determine the seating capacity of an auditorium with 30 rows of seats if there are 20 seats in the first row, 24 seats in the second row, 28 seats in the third row, and so on

Answers

Answer:

The seating capacity of the auditorium is 2,340.

Step-by-step explanation:

This question relates to an Arithmetic Progression (AP).

An Arithmetic Progression (AP) is a sequence of numbers in which the differences of every two consecutive numbers or terms are constant or the same.

Therefore, the seating capacity can be calculated using the an arithmetic progression (AP) formula as follows:

Seating capacity = (n / 2) * (2a_1 + (n - 1)d) ...................... (1)

Where;

n = number of rows = 30

a_1 = Number seats in the first row = 20

d = Common difference = 24 - 20 = 28 - 24 = 4

Substituting the values into equation (1), we have:

Seating capacity = (30 / 2) * ((2 * 20) + ((30 - 1) * 4))

Seating capacity =  15 * (40 + (29 * 4))

Seating capacity =  15 * (40 + 116)

Seating capacity =  15 * 156

Seating capacity = 2,340

Therefore, the seating capacity of the auditorium is 2,340.

Function f gives the temperature, in degrees Celsius, t hours after midnight. Choose the equation that represents the statement: “At 1:30 p.m., the temperature was 20 degrees Celsius.” Group of answer choices f (1:30) = 20 f (1.5) = 20 f (13:30) = 20 f (13.5) = 20

Answers

Answer:

D.

Step-by-step explanation:

The function f gives the temperature in degrees Celsius t hours after midnight.

Therefore, for the temperature at 12:00 AM (exactly midnight), we will have f(0).

For 1:00 AM, 1 hour after midnight, we will have f(1).

And for 12:00 PM (noon), we will have f(12).

We want to find the equation that represents the temperature at 1:30 PM.

1:30 PM is 13.5 hours after midnight or 1.5 hours after noon.

Therefore, the correct statement would be:

f(13.5)=20.

Hence, our answer is D.

The yield of corn in bushels per acre and the amount of rain in the growing season.

Identify the explanatory variable and the response variable, if possible.

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

2. Bushels per acre is the explanatory variable and amount of rain is the response variable.

3. Yield of corn is the explanatory variable and amount of rain is the response variable.

4. Amount of rain is the explanatory variable and bushels per acre is the response variable.

5. Rain is the explanatory variable and corn is the response variable.

Answers

Answer:

1. Amount of rain is the explanatory variable and yield of corn is the response variable.

Step-by-step explanation:

Explanatory Variable is the causal variable, which effects the other variable.

Response Variable is the resultant variable, which is effected by the other variable.

In this case, amount of rain effects the yield of corn (bushels per acre).

So, Amount of rain being causal effecting variable - is Explanatory Variable. Corn yield, being resultantly effected variable - is Response Variable.

Step-by-step explanation:

If the two congruent angles (angles A and B) of an isosceles
triangle are each twice the third, non-equal angle. (angle C)
find the measure of the non equal angle, angle C.

Answers

Answer:

If the third angle is x, the other two angles are 2x

 

The measure of the angles of a triangle must add up to 180 degrees

 

x + 2(2x) = 180

 

x + 4x = 180

 

5x = 180

 

x = 36

 

The other two angles are 2x = 2 * 36 = 72

 

The three angles are 36, 72, and 72 degrees

Step-by-step explanation:

EXAMPLE-

x+2x+2x=180

5x=180

x=180/5

x=36º third angle

the equal angles are each 2*36=72º

The required measure of three angles are 36, 72, and 72 degrees in the given triangle.

What is an Isosceles Triangle?

An Isosceles Triangle is defined as a triangle with two sides of equal length is an isosceles triangle.

Given that the third angle is x, the other two angles are 2x

We know that the measure of the angles of a triangle must add up to 180 degrees.

As per the given question, the equation would be as:

x + 2(2x) = 180

x + 4x = 180

5x = 180

x = 36

So, the other two angles are 2x = 2 × 36 = 72

Therefore, the required measure of three angles are 36, 72, and 72 degrees in the given triangle.
