Answer:

Answer:

52.48

Step-by-step explanation:

find the cross sectional area which is the triangle

triangle = 1/2 x 8.2 x 6.4 = 26.24

then, use the area to multiply by the extended length of 2

26.24 x 2 = 52.48

As part of a community service project at your high school, you are organizing a fund-raiser at the neighborhood movie theater. Money raised will benefit a summer camp for children with special needs. The admission charge is $10.00 per person, $5.50 of which is used to pay the movie theater’s rental fee. The remainder is donated to the summer camp fund.There are two variables involved in this problem. Which variable can best be designated as the dependent variable? As the independent variable?
a.
Independent variable - number of persons attending (or number of tickets sold);
Dependent variable - the amount donated
b.
Independent variable - the amount donated;
Dependent variable - number of persons attending (or number of tickets sold)
c.
Independent variable - number of persons attending (or number of tickets sold);
Dependent variable - the amount of the admission per person
d.
Independent variable - number of persons attending (or number of tickets sold);
Dependent variable - the amount paid towards the movie theater’s rental fee.

Answers

Independent variable is number of persons attending (or number of tickets sold) and Dependentvariable  is the amount donated

What is Statistics?

Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.

The number of persons attending (or number of tickets sold) is the independent variable because it is the variable that we can control or manipulate.

The amount donated, on the other hand, depends on the number of persons attending and is thus the dependent variable.

The more people that attend the fund-raiser, the higher the amount donated to the summer camp fund.

Independent variable - number of persons attending (or number of tickets sold);

Dependent variable - the amount donated

Hence, Independent variable is number of persons attending (or number of tickets sold) and Dependent variable  is the amount donated

The answer is
A.
Independent variable - number of persons attending (or number of tickets sold);
Dependent variable - the amount donated

Because, the number of persons attending is independent. No one knows how many people are attending. But the amount donated is depended upon the number of people attending.

Point M with coordinates (3,4) is the midpoint of the line AB and A has the point (-1,6). What is thepoint of B?

Answers

The midpoint of a line segment divides the line segment into equal halves. The point of B is (7,2)

Given that:

A = (-1,6)

M = (3,4)

Point B is represented as:

B = (x_2,y_2)

To calculate the coordinate of B, we use the following midpoint formula:

M = ((x_1 + x_2)/(2),(y_1 + y_2)/(2))

So, we have:

(3,4) = ((-1 + x_2)/(2),(6 + y_2)/(2))

Multiply through by 2

2 * (3,4) = (-1 + x_2,6 + y_2)

(6,8) = (-1 + x_2,6 + y_2)

By comparison:

6 = -1 +x_2  and

8 = 6 + y_2

So, we have:

6 = -1 +x_2

x_2 =6 + 1

x_2 =7

8 = 6 + y_2

y_2 = 8 - 6

y_2 = 2

Hence, the coordinate of B is (7,2)

How much time has elapsed between 12:11:30 and 15:24:55

Answers

Time elapsed = Final time - initial time

= 15:24:55 - 12:11: 30

= 3:13: 25

or, 3 hours, 13 minutes and 25 seconds has been elapsed.
We'll 15-12 = 3 , 24-11 =13 , and 55-30 = 25 so 3:13:25

Can a trapezoid and a square ever have the same area?

Answers

Answer:You can make a square have any area you want it to, by making its sideslonger or shorter. You just have to keep all the sides the same length andone of its angles 90 degrees, otherwise you won't have a square any more.-- You can make a trapezoid have any area you want it to, by making its sideslonger or shorter. You just have to keep one pair of sides parallel, otherwiseyou won't have a trapezoid any more.-- Since you can make a square with any area you want, and you can make atrapezoid with any area you want, there's no reason why you can't make oneof each, that both have the same area.-- And while you're at it, you could also make a circle that has the same areaas the square and the trapezoid.

Step-by-step explanation:

Final answer:

Yes, a trapezoid and a square can have the same area. Area is the measure of the space inside a shape and two different shapes can occupy the same amount of space. An example is provided to illustrate this.

Explanation:

Yes, a trapezoid and a square can have the same area. Area is simply a measure of the space inside a shape, and it's entirely possible for two different shapes to occupy the same amount of space. For instance, consider a square of side length 4 units. Its area would be 16 square units. Now consider a trapezoid with base lengths of 3 units and 5 units, and a height of 4 units. The area of a trapezoid is calculated as ((base1+base2)/2)*height, which would also give us 16 square units in this case. So, these two shapes - the square and the trapezoid - have the same area.
