Margo will pay $36 in interest after borrowing $600 with a 4% annual interest rate for 18 months. We calculate this using the simple interest formula.
Explanation:The question is asking us to figure out how much interest Margo will pay after borrowing $600 with a 4% annual interest rate, or simple interest rate, over the course of 18 months. A core concept here is understanding how simple interest is calculated.
The simple interest formula we'll be using is: Interest = Principal x Rate x Time. The Principal is the amount of money initially borrowed, Rate is the annual interest rate (in decimal form), and Time is the length of time the money is borrowed for, expressed in years.
So in Margo's case, the Principal is $600, the Rate is 4% (or 0.04 in decimal form), and Time is 18/12 or 1.5 years, because 18 months is equal to 1.5 years.
When we apply these amounts to the formula we get: Interest = $600 x 0.04 x 1.5, which equals $36. So Margo will pay $36 in interest.

passes through A(-3, 0) and B(-6, 5). What is the equation of the line that passes through the origin and is parallel to ?
Answer:
Equation of line , 5x + 3y = 0
Step-by-step explanation:
The slope of a line passing through points (x₁,y₁) and (x₂,y₂) is given by [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Here points are given by (-3,0) and (-6,5)
Slope[tex]=\frac{5-0}{(-6)-(-3)}=\frac{-5}{3}[/tex]
The slope of parallel lines are same. So slope of required line [tex]=\frac{-5}{3}[/tex]
Equation of a line with slope m passing through origin is given by
y =mx
So equation of line, [tex]y=\frac{-5}{3}x\\\\3y=-5x\\\\5x+3y=0[/tex]
Equation of line , 5x + 3y = 0
Answer: -5x -3y = 0

The Sanders family and the Wright family each used their sprinklers last summer. The Sanders family's sprinkler was used for 20 hours. The Wright family's sprinkler was used for 35 hours. There was a combined total output of 1025L of water. What was the water output rate for each sprinkler if the sum of the two rates was 40L per hour?
The water output rate for the Sanders family's sprinkler was 25 liters per hour, and for the Wright family's sprinkler was 15 liters per hour.
Let the water output rate as "x" liters per hour and the water output rate for the Wright family's sprinkler as "y" liters per hour.
Given that the combined total output of water from both sprinklers was 1025L, we can set up the following equation:
20x + 35y = 1025
We also know that the sum of the two rates is 40L per hour:
x + y = 40
x = 40 - y
Substituting this value of x into the first equation:
20(40 - y) + 35y = 1025
800 - 20y + 35y = 1025
15y = 225
y = 15
Substituting this value of y back into the second equation:
x + 15 = 40
x = 25
Therefore, the water output rate for the Sanders family's sprinkler was 25 liters per hour, and for the Wright family's sprinkler was 15 liters per hour.

Kevin has a spinner that has 10 equal sections and 2 sections of each color—red, blue, green, yellow, and purple. Kevin spins the spinner 180 times. Kevin determines about how many times the spinner will land on red or green, and his work is shown below.
Kevin's spinner will land on red or green approximately 72 times out of 180 spins since the probability of landing on red or green per spin is 0.4.
Explanation:The student's question involves determining the expected number of times a spinner will land on specific colors, given that the spinner is spun a large number of times. In this scenario, Kevin has a spinner with 10 equal sections with 2 sections of each color - red, blue, green, yellow, and purple. When Kevin spins the spinner 180 times, he wants to figure out how many times it will land on red or green.
Since there are 2 sections each of red and green out of a total of 10, the probability of landing on either red or green for a single spin is P(red or green) = P(red) + P(green) = 2/10 + 2/10 = 4/10 = 0.4. To find the expected number of times the spinner will land on red or green after 180 spins, we simply multiply the total number of spins by the probability of landing on red or green: 180 spins * 0.4 = 72 spins. Therefore, we can expect the spinner to land on red or green approximately 72 times out of 180 spins.

A friend is planning a trip to Alaska. He purchased a coat that is recommended for outdoor temperatures from −15°F−15°F negative 15 degrees cap f to 45°F
The question is about the temperature range of a coat and its ability to withstand extreme temperatures.
Explanation:The subject of this question is Physics, as it involves understanding the temperature range of a coat and its ability to withstand extreme temperatures.
Given that the coat is recommended for temperatures from -15°F to 45°F, it means that the coat is designed to provide sufficient insulation and protection within this temperature range. The negative symbol in -15°F indicates that it is below freezing point.
This suggests that the coat is designed to keep the wearer warm in sub-freezing temperatures, down to -15°F, and up to 45°F. It is important to note that the recommended temperature range may vary depending on individual tolerance, activity level, and wind chill factors.

What is the domain and range of f(x)=3x?
The required domain and range of the f(x) = 3x is (-∞, +∞) and (-∞, +∞) respectively.
What is a domain?The domain is defined as the values of the independent variable for which there is a certain value of the dependent variable exists in the range of the function.
Here,
The function f(x) = 3x is a linear function where the output (the range) is directly proportional to the input (the domain).
The domain of this function is the set of all real numbers because we can substitute any real number for x and get a valid output.
The range of the function is also the set of all real numbers because we can get any real number as the output by multiplying a real number by 3. Therefore, the range of the function is also all real numbers.
In interval notation, we can represent the domain and range as follows,

we know that
A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form [tex]\frac{y}{x}=k[/tex] or [tex]y=kx[/tex]
where
k is the constant of proportionality
In this problem we have
[tex]y=2.5x[/tex]
so
the constant of proportionality k is equal to
[tex]k=2.5[/tex]
therefore
the answer is
[tex]k=2.5[/tex]
The constant of proportionality in the equation [tex]y = 2.5x[/tex] is [tex]\boxed{2.5}.[/tex]
Further explanation:
The relation is defined as the relationship between the input values and output values.
The x coordinates are the domain of the function and the y coordinates are the range of the function.
Given:

Recall that a prime number is a natural number whose only factors are itself and 1 (for example, 2, 3, 5, . . . ). the goldbach conjecture, posed in 1742, claims that every even number greater than 2 can be expressed as the sum of two primes. for example, 4 = 2 + 2, 6 = 3 + 3, and 8 = 5 + 3. a deductive proof of this conjecture has never been found. test the conjecture for at least 10 even numbers and present an inductive argument for its truth. do you think the conjecture is true? why or why not?
Prime Number is a number whose only factors are itself and one. For example 1,3,5,7,11,13,17,19,23… Now consider the following arguments : Every even number greater than 2 can be expressed as sum of two primes. Now consider the following premises:
Premise 1 : 4 = 2 + 2
Premise 2 : 10 = 5 + 5
Premise 3 : 12 = 5 + 7
Premise 4 : 16 = 5 + 11
Premise 5 : 18 = 5 + 13
Premise 6 : 22 = 11 + 11
Premise 7 : 30 = 7 + 23
Premise 8 : 32 = 3 + 29
Premise 9 : 40 = 3 + 37
Premise 10 : 52 = 5 + 47
Premise 11 : 100 = 3 + 97
Conclusion : every whole number is sum of two prime numbers.
All 11 cases are different, yet the rule applies to all. This outcome offers a strong inductive argument in favor of the conclusion or rule specified. It can be strengthened by additional cases that confirm the rule. Conjecture specified will be true because each number can be specified as sum of two primes. As each whole number will have difference os 1, 2, 3, 5, or 7 between the number and the nearest prime number. Consider the following example :
34 = 31 + 3
36 = 33 + 3
Hence the conjecture “Every number greater than two can ve expressed as the sum of two primes” is true.
