aaliyah compares the heights of two plants to see which plant grows more per day. The table shows the height of Plant 1, in centimeters, over 5 days. The graph shows the height of Plant 2, in centimeters, over 10 days. aaliyah says that since Plant 1 grows 4cm per day and Plant 2 grows 6cm per day, plant 2 grows more per day. Do you agree with aaliyah? Explain your response.
A. I agree that plant 2 grows more per day than plant 1, but I disagree with aaliyahs's reasoning.

What is a proportional relationship?A proportional relationship between two variables is one in which one variable is a multiple of the other.
The possible table in the question is presented as follows;
Plant 1
Week; 2, 3, 4, 5Height; 8, 12, 16, 20The values on the graph are;
Plant 2
Week; 2, 4, 6, 8, 10Height; 4, 8, 12, 16, 20The rate, r1, of growth of Plant 1 is therefore;
r1 = 8 cm/(2 weeks) = 4 cm/week
The rate, of growth, r2, of plant 2 is found as follows;
r2 = 4 cm/(2 weeks) = 2 cm/week
Given that Plant 1 grows faster at 4 cm/week, than Plant 2, that grows at 2 cm/week, the correct statement is since Plant 1 grows 4 cm/week and Plant 2 grows 2 cm/week, Plant 1 grows more per day.
The correct option is therefore;
C. I think that plant 1 grows more per day and I disagree with Aaliyah's reasoning

cos A = - (a² - b² - c²) / (2 · b · c)
cos A = - (25² - 2² - 24²) / (2 · 2 · 24)
cos A = - 0.469

andrew took a handful of change out of his picket adn noticed taht he was only holding dimes adn quarters in his hand. he counted that he had 22 coins that ammounted to $4. how many quarters and how many dimes does andrew have?
Answers
Andrew has 7 dimes and 15 quarters, as obtained from the system of linear equations so formed.
What is a system of linear equations?A system of linear equations is a set of two or more linear equations. Linear equations refer to the equations that involve two or more variables in the form of "ax + b".
Given:
Number of coins = 22; only dimes and quarters.Amount of coins = $4To find: Number of dimes and quarters.
Finding:
Now, 1 dime = 10 cents and 1 Quarter = 25 centsAlso, 100 cents = $1=> By unitary method, $4 = 4(100) = 400 cents
Let the number of dimes be d and number of quarters be q.Now, According to question, a system of linear equations follows:d + q = 22 (Number of coins) => d = 22 - q (eqn1)
and 10d + 25q = 400 (amount of coins)
=> 10 ( 22 - q ) + 25q = 400
=> 220 - 10q + 25q = 400
=> 15q = 400 - 220 = 180
=> q = 12, i.e., number of quarters = 22 upon the solving of this system of linear equations.
On substituting the value of q in eqn1, we get: d = 22 - 15 = 7, i.e., number of dimes = 7.
Hence, Andrew has 7 dimes and 15 quarters, as obtained from the system of linear equations so formed.
