Multiply and simplify. 3/9 x 5/9
Answer:
5/27
Step-by-step explanation:
3/9 x 5/9
= ( 3 x 5 )/( 9 x 9 )
9 can be splitted as 3 x 3
= ( 3 x 5 )/( 3 x 3 x 9 )
= 5/( 3 x 9 )
= 5/27
Answer:
\(\frac{5x}{27}\)
Step-by-step explanation:
Cancel the number 3/9 = 1/3
= 1/3 x 5/9
Apply the function rule
1 · x · 5
3 · 9
Multiply the numbers 1 · 5 = 5
\(\frac{5x}{3 }\)· \(9\)
Now just Multiply the numbers: 3 · 9 = 27
= \(\frac{5x}{27}\)

A family bought a total of 12 adult and child tickets to a magic show. Adult tickets are $8.50 each and child tickets are $5.50 each. The family paid a total of $90. How many adult tickets, x, and child tickets, y, did they buy?
Answer: They bought 8 adult tickets and 4 child tickets.
Step-by-step explanation:
x = amount of adult tickets bought
y= amount of child tickets bought
1. Set up a system
8.5x+5.5y = 90
x+y = 12
2. Solve for a variable (I'll do x for example)
y=12-x
3. Substitute y into the first equation
8.5x+5.5(12-x)=90
8.5x+66-5.5x=90
3x=24
x=8
4. Substitute x back into the second equation
8+y=12

(a). The Tanakas paid a total of $523,906.40 for the townhome.
(b). The Tanakas paid $206,906.40 in interest on their mortgage over the 15-year period.
What is simple intresst?Simple interest is the type of interest that is calculated on the principal amount only.
It is a fixed percentage of the principal amount that is charged or earned over a certain period of time, without any compounding of interest.
(a) The total amount they ended up paying for the townhome is the sum of the down payment and the total amount of the mortgage payments.
Down payment = $41,000
Total amount of mortgage payments = monthly payment x number of payments = $2675.04 x 12 months/year x 15 years = $482,906.40
Total amount paid = down payment + total amount of mortgage payments = $41,000 + $482,906.40 = $523,906.40
(b) The amount of interest paid on the mortgage can be calculated by subtracting the principal (the amount borrowed) from the total amount paid.
Principal = Total cost of townhome - Down payment = $358,000 - $41,000 = $317,000
Total interest paid = Total amount paid - Principal = $523,906.40 - $317,000 = $206,906.40

list seven advantages that aluminum parallel-flow plate-and-fin evaporator has over a standard round copper tube plate-and-fin evaporator.
The aluminum parallel-flow plate-and-fin evaporator has several key advantages over the standard round copper tube plate-and-fin evaporator are Lighter Weight, Improved Heat Transfer Efficiency.
An evaporator is a device used in air conditioning and refrigeration systems to remove heat from the refrigerant, which helps to cool down the air. There are two main types of evaporators: the aluminum parallel-flow plate-and-fin evaporator and the standard round copper tube plate-and-fin evaporator.
The parallel-flow design of the aluminum evaporator provides a larger surface area for heat transfer, which results in more efficient cooling. This means that less energy is required to achieve the same cooling effect.
Reduced Pressure Drop: The parallel-flow design also reduces the pressure drop in the refrigerant, which can improve the overall efficiency of the air conditioning or refrigeration system.
Aluminum is lighter than copper, which makes the aluminum evaporator easier to handle and install. This can be especially important in large air conditioning or refrigeration systems where weight and handling can be a significant concern.
Increased Durability: Aluminum is a more durable material than copper, which means that the aluminum evaporator is less likely to suffer from corrosion or other types of damage over time.
Better Resistance to Leakage: The parallel-flow design of the aluminum evaporator provides a tighter seal, which reduces the risk of refrigerant leakage. This helps to maintain the efficiency of the air conditioning or refrigeration system.
Lower Maintenance Costs: The increased durability and better resistance to leakage of the aluminum evaporator can help to lower maintenance costs over time.
Improved Environmental Performance: The improved efficiency and reduced pressure drop of the aluminum evaporator can help to lower the energy consumption of the air conditioning or refrigeration system. This can result in a reduction in greenhouse gas emissions and other environmental impacts.

I need a thorough explanation on how you got your answer and the graphing calculator/equation you used to solve it.
We will need to use the following formulas
\(\begin{gathered} X=\frac{1}{N}\sum ^N_{i=1}x_i \\ Y=\frac{1}{N}\sum ^N_{i=1}y_i \\ m=\frac{\sum^N_{i=1}(x_i-X)(y_i-Y)}{\sum^N_{i=1}(x_i-X)^2} \\ \text{and} \\ r=\frac{\sum^N_{i=1}(x_i-X)(y_i-Y)}{\sqrt{\sum^N_{i=1}(x_i-X)^2\sum^N_{i=1}(y_i_{}-Y)}^2^{}} \\ \text{and} \\ Y=mX+b \end{gathered}\)In our case, using a calculator
\(X=5.5,Y=555.6\to\text{ means of the values of x and y, respectively}\)Therefore,
\(\begin{gathered} SS_x=\sum ^N_{i=1}(x_i-X)^2=82.5 \\ SP=\sum ^N_{i=1}(x_i-X)(y_i-Y)=1153 \\ \Rightarrow m=\frac{1153}{82.5}=13.975\ldots \\ \Rightarrow m\approx14 \end{gathered}\)Finding b,
\(\begin{gathered} Y=mX+b \\ \Rightarrow b=Y-mX \\ \Rightarrow b=555.6-\frac{1153}{82.5}\cdot5.5=478.73\ldots \\ \Rightarrow b\approx479 \end{gathered}\)Thus, the equation of the line of best is y=14x+479.
As for the correlation coefficient,
\(\begin{gathered} \sum ^N_{i=1}(x_i-X)(y_i-Y)=1153 \\ \sum ^N_{i=1}(x_i-X)^2=SS_x=82.5 \\ and \\ \sum ^N_{i=1}(y_i-Y)^2=SS_y=16118.4 \end{gathered}\)Therefore,
\(\begin{gathered} \Rightarrow r=\frac{1153}{\sqrt[]{82.5\cdot16118.4}}=0.9998\ldots\approx1 \\ \Rightarrow r=1 \end{gathered}\)Then, the Correlation Coefficient is r=1.
The r is practically 1, the model is considered a good fit; in fact, it is a perfect fit (strong relationship)
Summation Notation
Consider the expression
\(\sum ^N_{i=1}x_i\)Notice that there are 10 values of x in the table, order them in the following way
\(x_1=1,x_2=2,\ldots,x_{10}=10\)Then, after setting N=10,
\(\sum ^{10}_{i=1}x_i=x_1+x_2+\cdots+x_{10}=1+2+\ldots+10=55\)Another example,
\(\begin{gathered} \sum ^N_{i=1}y_i,N=10 \\ \Rightarrow\sum ^{10}_{i=1}y_i=y_1+y_2+\cdots+y_{10}=492+507+\cdots+618 \end{gathered}\)We found that X=5.5 (see above); then,
\(\begin{gathered} \sum ^{10}_{i=1}(x_i-X)^2=(x_1-X)^2+(x_2-X)^2+\cdots(x_{10}-X)^2=(1-5.5)^2+(2-5.5)^2+\cdots(10-5.5)^2 \\ \Rightarrow\sum ^{10}_{i=1}(x_i-X)^2=(1-5.5)^2+(2-5.5)^2+\cdots(10-5.5)^2 \end{gathered}\)Number of Computers

are produced in 5 days.
Find the unit rate of computers per day using the graph.
Unit rate:
computers per day
The unit rate of computers per day using the graph is that 12 computers are made per day.
What is a unit rate?The unit rate is how many units of quantity correspond to the single unit of another quantity. We say that when the denominator in rate is 1, it is called unit rate. Unit rates is said to be the amount of something in each unit or per unit.
How to find the unit rate of computers per dayTo obtain the unit rate of computers sold per day using the graph, we need to obtain the slope of the graph, which is the change in y per change in x
So, it is given by:
\(\text{Slope} = \dfrac{\text{change in y}}{\text{change in x}}\)
\(\text{Slope} = \dfrac{\text{y}_2-\text{y}_1}{\text{x}_2-\text{x}_1}\)
\(\text{y}_2 = 60 , \ \text{y}_1 = 36 , \ \text{x}_2 = 5, \ \text{x}_1 = 3.\)
\(\text{Slope} = \dfrac{(60 - 36)}{(5 - 3)} = \dfrac{24}{2} = 12\)
\(\bold{Slope = 12}\)
Unit rate = 12 computers per day.

A student measures the mass of a sample is 2.7 grams. What is the percent error, given that the correct mass is 2.58 grams? Round to the nearest hundredth of a percent.
Answer:
the percent error in the student's measurement is 4.65%.
Step-by-step explanation:
The percent error can be calculated using the formula:
| (measured value - actual value) / actual value | * 100%
In this case, the measured value is 2.7 grams and the actual value is 2.58 grams. Substituting these values into the formula, we get:
| (2.7 - 2.58) / 2.58 | * 100% = 4.65%

And please clarify your answers in a simple language
Given the equations a × b = 5742 × 6368, a × c = 5748 × 6362, and c × b = 5738 × 6372, we need to determine the relationship between the three variables a, b, and c.
By comparing the given equations, we notice that the numbers on the right-hand side of each equation are very close to each other, differing only by small amounts. This suggests that a, b, and c are approximately equal.Since a × b, a × c, and c × b involve the same numbers with slight variations, we can conclude that a, b, and c are all very close in value.
Therefore, the inequality we can infer from this information is a ≈ b ≈ c, indicating that a, b, and c are approximately equal.
In simple terms, based on the given equations, it suggests that the values of a, b, and c are very similar or approximately equal to each other.
