Answer 1

Answer:

side = 7.5 cm

Step-by-step explanation:

7x-3 = 3(x+1)

7x-3 = 3x+3

reduce:

4x = 6

x = 1.5

side = 3(1.5)+3 = 7.5 cm

Student Council is selling tickets to the Winter
Dance. Tickets cost $5 per person or $8 per
couple. To cover expenses, at least $1200
worth of tickets must be sold. No more than 500
students can fit in the gym where the dance is
being held.
List two combinations of tickets that could be sold, so
that Student Council makes a profit, yet stays under the
room capacity.

Answers

Answer:

Two possible combinations are;

1) 200 single and 30 couples

2) 150 single and 57 couples

Step-by-step explanation:

The given parameter in the question are;

The cost of ticket per person = $5

The cost of tickets per couple = $8

The minimum worth of tickets to be sold = $1,200

The maximum number of students that can fit in the gym = 500

Let 'x' represent the number of single persons that attend the dance and let 'y' represent the number of couple that attend, we have;

5·x + 8·y ≥ 1,200

x + y ≤ 500

Making 'y' the subject of both equations gives;

y ≥ 150 - 5·x/8

y ≤ 500 - x

From the graph of the inequalities created with Microsoft Excel, we have;

When x = 200, and y = 30, we get;

5 × 200 + 8 × 30 = 1240 > 1200

200 + 30 × 2 = 460 < 500

We also have;

x = 150, and y = 57, we get

Equating both values of 'y', we get;

5 × 150 + 8 × 57 = 1206 > 1200

150 + 57 × 2 = 264 < 500

Therefore, from the acceptable region in the graph, we have the following two possible combinations

1) 200 single and 30 couples

2) 150 single and 57 couples

Answers

Answer: Choice B

==========================================

Explanation:

Here's a slightly more detailed breakdown of what's going on

3x + 2y = 15 ... start with the first equation

3x + 2( y ) = 15 .... the parenthesis don't change the expression

3x + 2( 3x+5) = 15 ... replace y with 3x+5; since y = 3x+5

From here, you solve for x like you would any other single variable equation. Once you know x, you can determine y through y = 3x+5.

City y is 10 miles north of city x city z is 24 miles east of city x how long is the straight roads connecting cities y and z?

Answers

Answer:

26 miles

Step-by-step explanation:

Using Pythagoras rule :

d = straight road connecting city Y and Z :

d = sqrt(xy² + xz²)

d = sqrt(10² + 24²)

d = sqrt(100 + 576)

d = sqrt(676)

d = 26 miles

Complete the square
to find the vertex
of this parabola.
x?+8y+2x - 23=0

Answers

Answer:

The vertex of the parabola is;

([-1], [3])

Step-by-step explanation:

The given quadratic equation is presented as follows;

x² + 8·y + 2·x - 23 = 0

The equation of the parabola in vertex form is presented as follows;

y = a·(x - h)² + k

Where;

(h, k) = The vertex of the parabola

Therefore, we have;

x² + 8·y + 2·x - 23 = 0

8·y = -x² - 2·x + 23

y = 1/8·(-x² - 2·x + 23)

y = -1/8·(x² + 2·x - 23)

y = -1/8·(x² + 2·x + 1 - 23 - 1) = -1/8·(x² + 2·x + 1 - 24)

y =  -1/8·((x + 1)² - 24) =  -1/8·(x + 1)² + 3

Therefore, the equation of the parabola in vertex form is y =  -1/8·(x + 1)² + 3

Comparing with y = a·(x - h)² + k, we have;

a = -1/8, h = -1, and k = 3

Therefore, the vertex of the parabola, (h, k) = (-1, 3).

When would you use a pictograph? to compare change over time if the data is numerical to save space for a large set of data if the data is categorical

Answers

Answer:

to save space for a large set of data

if the data is categorical

Step-by-step explanation:

The pictograph is used if the data is categorical

What is a pictograph?

A pictograph is a type of graph that uses pictures or symbols to represent data. It is best used when the data is categorical or non-numerical. For example, a pictograph can be used to show the favorite types of fruits of a group of people or the most popular colors of a group of cars.

Pictographs are useful for presenting data in a visually appealing way that is easy to understand, especially for younger or less experienced readers. They are less useful for comparing change over time or for presenting large sets of numerical data, as they can become cluttered and difficult to read.

Given data ,

Let the pictograph be represented as A

Now , pictographs are less useful for comparing change over time or for presenting large sets of numerical data, as they can become cluttered and difficult to read.

For example, if you want to show how the population of a city has changed over the years, a line graph or a bar graph would be a better choice than a pictograph

Hence , pictographs are useful if there is categorical data
