The given equation is
[tex]\rightarrow 9r+16=\frac{\pi}{5}[/tex]
The value of π is 3.14 or [tex]\frac{22}{7}[/tex] that is a fixed Value.
[tex]\rightarrow 9r +16=\frac{3.14}{5}\\\\9r+16=0.628\\\\9r=0.628-16\\\\9r=-15.372\\\\r=\frac{-15.372}{9}\\\\r=-1.708[/tex]
So, the given equation is Literal ,because variable value is Known.
A literal equation is an equation that has at least one letter or one unknown variable.
[tex]9r + 16= \frac \pi 5[/tex] is a literal equation because it has letter r
Given that:
[tex]9r + 16= \frac \pi 5[/tex]
By analyzing the equation, we have:
[tex]9, 16, 5 \to[/tex] number
[tex]r \to[/tex] letter
[tex]\pi \to[/tex] constant
Because r is a letter, then the equation is a literal equation

Answer:
the answe is 60 on usapreptest
Step-by-step explanation:
The rate at which Ebony driving is 60 miles per hour.
The given coordinate point is (3, 180).
Average rate is a measure of how much the function changed per unit, on average, over that interval.
Here, 180/3 = 60 miles per hour
Therefore, the rate at which Ebony driving is 60 miles per hour.

Name the property illustrated by the statement:
If d+1=f, then d=f-1 .
It's a property of equality, but I'm not sure which one. Please explain which one it is and why it's that one. Thanks! :-)
Answer:
subtraction property of equality.
Step-by-step explanation:
IF any number is added on both sides of equation then it is addition property of equality.
If any number is subtracted from both sides of the equation then it is subtraction property of equality.
If d+1=f, then d=f-1 .
[tex]d+1=f[/tex]
To get 'd' alone , 1 is subtract from both sides
[tex]d=f-1[/tex]
1 is subtract from both sides of the given equation.
So it subtraction property of equality.

The graph shows the cost of purchasing T-shirts. Find the constant rate of change for the graph. Then explain what points (0,0) and (1,9) represent
Answer:
Constant rate of change is 9
Step-by-step explanation:
To find the constant rage of change we pick 2 points from the graph
points (0,0) and (1,9)
Rate of change is the slope
[tex]slope =\frac{y_2-y_1}{x_2-x_1}[/tex]
[tex]slope =\frac{9-0}{1-0}=9[/tex]
Slope = 9/1
Constant rate of change is 9
points (0,0) and (1,9) represent 9 units up from (0,0) and 1 units the right

Cupcakes are packed 6 to a box. If Abby only buys full boxes of cupcakes give two possible numbers of cupcakes that she could buy.
Answer:
The two possible numbers of cupcakes that she could buy can be 6,12,18 etc.
Step-by-step explanation:
As given:
Cupcakes are packed 6 to a box.
Abby only buys full boxes of cupcakes.
So, basically if she only wants full boxes, then she must get cupcakes in multiples of 6. Like : 6,12,18,24....
Therefore, any number that is a multiple of six is acceptable here.

[Statistics and Probability] How to find if something is mutually exclusive given a sample space?
To find if events A and B are mutually exclusive given a sample space, check if they can occur at the same time. If P(A AND B) = 0, they are mutually exclusive. If they share common outcomes, they are not mutually exclusive.
To determine if two events in a sample space are mutually exclusive, you need to evaluate if the two events can occur simultaneously. If two events, A and B, are mutually exclusive, this means that they cannot happen at the same time, and therefore the probability of A AND B occurring together, denoted as P(A AND B), is zero.

A park district has 25 elm trees and 20 oak trees to be planted.They are separating the trees for different areas.They want each area to have the same number of elm trees and the same number of oak trees. What is the greatest number of areas that can be created?
Answer: There are 5 number of areas that can be created.
Step-by-step explanation:
Since we have given that
Number of elm trees = 25
Number of oak trees = 20
According to question, They want each area to have the same number of elm trees and the same number of oak trees.
So, the greatest number of areas that can be created is H.C.F. of 25 and 20 = 5.
Hence, there are 5 number of areas that can be created.

In a lab, a 30% acid solution is being mixed with a 5% acid solution to create a 10% acid solution. What is the ratio of the amount of the 30% solution to the amount of 5% solution used to create the 10% solution?
1:3
1:4
1:5
1:6
1:4 is the answer to the question.
Answer:
Option B. 1 : 4.
Step-by-step explanation:
In a lab 30% acid solution and 5% acid solution were mixed to prepare 10% acid solution.
We have to calculate the ratio of both the acids should be mixed to prepare 10% acid solution.
Let the volume of 30% solution was used = x ml
and the volume of 5% acid was used = y ml
Therefore the equation will form as
30%.x + 5%.y = 10%.(x + y)
0.30x + 0.05y = 0.10(x + y)
Now we transfer the similar terms in one side of the equation.
0.30x - 0.10x = 0.10y - 0.05y
0.20x = .05y
[tex]\frac{x}{y}= \frac{.05}{0.20}[/tex]
x : y :: 1 : 4
Therefore solutions will be mixed in a ratio of 1 : 4
Option B. 1 : 4 is the right answer.

The perimeter of a rectangle is 24 feet. The length is 3 feet less than twice the width. Which of the following systems would be used to solve this problem ???
The system of equations are 24 = 2(l + w) and l = 2w - 3 option third is correct.
What is the area of the rectangle?It is defined as the area occupied by the rectangle in two-dimensional planner geometry.
The area of a rectangle can be calculated using the following formula:
Rectangle area = length x width
Let l be the length and w be the width of the rectangle
By the formula of perimeter:
24 = 2(l + w)
l = 2w - 3 (The length is 3 feet less than twice the width)
The system of equations:
24 = 2(l + w)
l = 2w - 3
Thus, the system of equations are 24 = 2(l + w) and l = 2w - 3 option third is correct.
