x - price of adult tickets, y - price of child tickets, the equation in the standard form is:
15x + 9y = 90 ⇒ 5x + 3y = 30Part By-intercept is obtained when x = 0
15*0 + 9y = 909y = 90y = 10It represents the amount of child tickets if no adult tickets sold
x-intercept is obtained when y = 0
15x + y*0 = 9015x = 90x = 6It represents the amount of adult tickets if no child tickets sold
Part CConverting the equation into slope-intercept form of y = mx + b
5x + 3y = 303y = -5x + 30y = -5/3x + 30/3y = -5/3x + 10Part DThe slope is -5/3. It represents the negative ratio of ticket pricesRelated Questions

Subtract 3 from both sides of the equation.
-5x= 16
Divide by -5 on both sides
X= -3.2
Answer:
x = -3.2
Step-by-step explanation:
First, subtract 3 from both sides of the equation so you're left with
(-5)x = 16
Then, divide both sides by -5
x = -3.2
A community swimming pool is a rectangular prism that is 30 feet long, 12 feet wide, and 5 feet deep. The wading pool is half as long, half as deep, and the same width as the larger pool.
How many times greater is the volume of the swimming pool than the volume of the wading pool?
Answers
Answer:
Answer:
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.
Step-by-step explanation:
By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:
Community swimming pool
V_{c} = l\cdot w\cdot h (1)
Wading pool
V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)
Where:
l – Length of the swimming pool, measured in feet.
h – Depth of the swimming pool, measured in feet.
w – Width of the swimming pool, measured in feet.
V_{c} – Volume of the community swimming pool, measured in cubic feet.
V_{w} – Volume of the wading swimming pool, measured in cubic feet.
The ratio of the volume of the community swimming pool to the volume of the wadling pool is:
\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)
\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }
\frac{V_{c}}{V_{w}} = 4
The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.Step-by-step explanation:
The volume of the swimming pool is 4 times the volume of the wadding pool
What is the volume of a Rectangular box?
The volume of a rectangular box is given by the formula ,
Volume of Rectangular box = Length x Width x Height
where L = length of the rectangular box
W = width of the rectangular box
H = height of the rectangular box
Volume of Rectangle = Area of Rectangle x Height
Given data ,
Let the length of the swimming pool be L = 30 feet
Let the width of the swimming pool be W = 12 feet
Let the height of the swimming pool be H = 5 feet
So , volume of a rectangular box is given by the formula ,
Volume of Rectangular box = Length x Width x Height
Substituting the values in the equation , we get
Volume of Rectangular swimming pool = 30 x 12 x 5
Volume of Rectangular swimming pool = 1800 feet³
Now ,
The length of the wading pool be l = 15 feet
The width of the wading pool be w = 6 feet
The height of the wading pool be h = 5 feet
Volume of Rectangular wading pool = Length x Width x Height
Substituting the values in the equation , we get
Volume of Rectangular wading pool = 15 x 6 x 5
Volume of Rectangular wading pool = 450 feet³
Now , the volume of the swimming pool = N x Volume of Rectangular wading pool
To calculate the value of N ,
1800 = N x 450
Divide by 450 on both sides of the equation , we get
N = 4 times
Therefore , the value of N is 4
Hence , The volume of the swimming pool is 4 times the volume of the wadding pool

Interval or scale on a graph definition
Answers
The interval scale is a quantitative measurement scale where there is order, the difference between the two variables is meaningful and equal, and the presence of zero is arbitrary. It measures variables that exist along a common scale at equal intervals. The measures used to calculate the distance between the variables are highly reliable.

In math, a scale in graphs can be defined as the system of marks at fixed intervals, which define the relation between the units being used and their representation on the graph.

Brianna needs to buy a new backpack for her European trip. The one she wants costs $150. She leaves in 5 months. How much should she save each month? What if she wants to leave in 3 months? How much does she need to save then?
Answers
Answer: she should save 30 dollars a month for 5 months and 50 a month for 3 months
Step-by-step explanation:
150 divided into 5 months = 30
150 divided into 3 months = 50
If she wants to leave in 5 months, then she should save $30 each month and if she wants to leave in 3 months then she should save $50 each month.
What is division?The division is the process of sharing a collection of items into equal parts and is one of the basic arithmetic operations in maths.
We may face different situations every day where we use the division technique.
Given that, Brianna needs to buy a new backpack for her European trip. The one she wants costs $150.
We need to find the amount she should save if she is leaving in 5 and 3 months.
Let she saved $x in each case,
so,
For 5 months =
5x = 150
x = 30
And,
For 3 months =
3x = 150
x = 50
Hence, if she wants to leave in 5 months, then she should save $30 each month and if she wants to leave in 3 months then she should save $50 each month.
