The complete question is added as an attachment

From the question, we have the following parameters that can be used in our computation:

The points on the line are

(-3, 2) and (2, -1)

So, the slope (m) is

m = (-1 - 2)/(2 + 3)

Evaluate

m = -3/5

The equation of the perpendicular line is then calculated as

y = -1/m(x - x1) + y1

Where

X + Y = 33

It is assumed that two times the number of employees at the larger location is three times the number at the smaller location. The equation for this is as follows:

2Y = 5X + 3

Because we already know that X + Y = 33, we can write it as X = 33 - Y.

Let us now plug X into the above equation.

2Y = 5*(33 - Y) + 3

2Y = 165 - 5Y + 3

7Y = 168

Y = 168 / 7

Y = 24

Let us now compute the value of X.

Answer: 2,380 people attend the game

Step-by-step explanation:

Using the strategy below, we can identify the lightest heart (the pure-hearted person) using the balance only twice, as required by the puzzle.

we can use the following strategy:

Divide the 8 people into 3 groups of 3, and leave 2 people aside.

Weigh any two of the three groups against each other using the balance.

If the two groups weigh the same, then the pure-hearted person must be in the remaining group of two that we left aside. Weigh one of the remaining people against another one from this group.

If they weigh the same, then the remaining person is the pure-hearted one. If one is heavier, then that person is a sinner, and the lighter one is the pure-hearted person.

If the two groups from step 2 are not of the same weight, then the pure-hearted person must be in one of these two groups. Take any two people from the group that weighs more and weigh them against each other.

If they weigh the same, then the pure-hearted person is in the remaining group that was not weighed, and we can find them by weighing one person from that group against another.

If one of the two people weighed in step 5 is lighter, then that person must be the pure-hearted person. If they are the same weight, then the pure-hearted person is in the other group that was not weighed, and we can find them by weighing one person from that group against another.

Step-by-step explanation:

The correct statements are: B and C.

What is the linear functions?

linear functions, specifically comparing their rate of change and y-intercepts.

To compare the properties of Function A and Function B, we need to first determine the equations for both functions.

From the table, we can see that Function A has a rate of change of 3 and a y-intercept of 4. Therefore, the equation for Function A is y = 3x + 4.

To find the equation for Function B, we can use two of the given points to calculate its rate of change and y-intercept. Using the points (1, 2) and (4, 14), we get:

rate of change = (14 - 2) / (4 - 1) = 4

y-intercept = 2 - 4(1) = -2

Therefore, the equation for Function B is y = 4x - 2.

Now we can compare the properties of the two functions:

A. The rate of change of Function A is greater than the rate of change of Function B. False, since the rate of change of Function A is 3, which is less than the rate of change of Function B, which is 4.

B. The rate of change of Function A is less than the rate of change of Function B. True, since the rate of change of Function A is 3, which is less than the rate of change of Function B, which is 4.

C. The y-intercept of Function A is greater than the y-intercept of Function B. True, since the y-intercept of Function A is 4, which is greater than the y-intercept of Function B, which is -2.

D. The y-intercept of Function A is equal to the y-intercept of Function B. False, since the y-intercept of Function A is 4 and the y-intercept of Function B is -2.

E. The y-intercept of Function A is less than the y-intercept of Function B. False, since the y-intercept of Function A is 4, which is greater than the y-intercept of Function B, which is -2.

F. The rate of change of Function A is equal to the rate of change of Function B. False, since the rate of change of Function A is 3 and the rate of change of Function B is 4.

[tex]x = 180 - 111[/tex]

[tex]x = 69[/tex]

Answer:

69°

Step-by-step explanation:

An angle is a measure of a turn, measured in degrees or °. Angles are made up of two rays, making the sides of the angle.

There are right angles (exactly 90 degrees), acute angles (less than 90 degrees), obtuse angles (more than 90 degrees), and reflex angles (more than 180 degrees).

We can see that if there is a straight line, the angles must add up to 180°. To solve for the value of x, we can use this equation:

Therefore, the measure of angle x = 69°

The number 25 can be represented as a decimal by simply writing it as 25.0 or 25.00

The number 25 can be represented as a decimal by simply writing it as 25.0 or 25.00. This is because decimal notation is a way of writing numbers that uses a decimal point to separate the whole number part from the fractional part.

In this case, since 25 is a whole number and has no fractional part, we can represent it in decimal form by adding a decimal point and a zero or two zeros after it to indicate that there are no decimal places.

Alternatively, we can also represent 25 as a decimal by dividing it by 1, which does not change its value, and then expressing the quotient as a decimal. Since 25 divided by 1 equals 25, we can write 25 as a decimal by dividing 25 by 1 and writing the quotient as follows:

25 ÷ 1 = 25.000000... (with the decimal places repeating indefinitely)

However, in most cases, it is sufficient to represent 25 as 25.0 or 25.00, since these notations convey that the number has no fractional part.

Note that the angle indicated by the question mark is 75°. See the explanation below.

Given that the angle at the vertex that they (the equilateral triangle and the square share) is a right angle or 90 degrees.

This means that the middle angle of the equilateral triangle is 60° this is because an "equilateral" triangle has 3 equivalent sides and, therefore, 3 equivalent angles.

Since the sum of the 3 angles of ANY triangle is 180°, then 180/3 = 60° for each angle.

Because the angle at the vertex is "splitting" a right angle, or 90 degrees which belongs to the square, then that leaves 2 smaller angles on each side of the 60° angle,

or 90 - 60

=30/2

The solution of the given problem of surface area comes out to be Tara and Veronica will need about 15.26 bottles of paint to cover the banner.

Its surface area is a reliable indicator of its overall size. When figuring out the right triangle squared, the environment is taken into account. The surface area of everything determines its overall size. The total of the volumes from each of the twelve vertical sides makes up the water volume inside a cuboid. Utilize the following formula to get the box's dimensions: The region is represented by 2lh, 2lw, & 2hW. (SA). The area is represented by the flexible shape's entire surface area.

Here,

To calculate the number of paint bottles needed, we need to first find the area of the parallelogram-shaped banner.

Area = base × height

The apothem is given as 9.52 cm, which is also the height of one of the triangles. The base of each of these triangles is half of the length of the banner, which is 6.8/2 = 3.4 cm. Using the Pythagorean theorem, we can solve for the height "h" of each triangle:

h² = (9.52)² - (3.4)²

h ≈ 8.56 cm

So the total height of the parallelogram is twice this value, or approximately 17.12 cm. Therefore, the area of the banner is:

Area = b × 17.12

864 × 2.54² ≈ 5574.14 cm²

So the area of the banner is:

Area = b × 17.12 = 2(6.8 + b) × 8.56 - 5574.14

Simplifying this expression, we get:

Area = 17.12b - 226.67

Now we can solve for "b" by setting this expression equal to the area of the banner that can be painted:

16(24) = 384 square feet = 384 × 144 ≈ 55302.74 cm²

17.12b - 226.67 = 55302.74

17.12b = 55402.41

b ≈ 3232.87 cm

Finally, we can calculate the area of the painted portion of the banner:

Area painted = (6.8 + b) × 17.12 - 6

Area painted ≈ 5826.24 cm²

To find the number of paint bottles needed, we divide the area painted by the coverage of one bottle:

Number of bottles = Area painted / (16 × 24)

Number of bottles ≈ 15.26

So Tara and Veronica will need about 15.26 bottles of paint to cover the banner.
