By finding the Least Common Multiple (LCM) of 4 and 10, we can discover that the math club and Spanish club will coincide every 20 days.
Explanation:This query relates to the concept of the Least Common Multiple (LCM). As the math club convenes every 10 days and the Spanish club convenes every 4 days, we need to find when these meetings will coincide again. In other words, we are finding the LCM of 4 and 10. This tells us the least common multiple days that the two clubs meet.
Let's breakdown the calculation:
First, list the prime factors of each number. For 4, that would be 2x2, and for 10, it would be 2x5.Next, take all the unique prime factors and multiply them together. So, 2x2x5 = 20.Therefore, the Spanish club and the math club will meet on the same day every 20 days.

Solve 3a+4b=1-2c/d for c.
(Can you please show all your steps?)
Hello!
To solve for c, we will need to use SADMEP. SADMEP is strictly used to solve algebraic equations. It is an acronym for subtraction, addition, division, multiplication, exponents, and parentheses. There are some cases in which we need to divide or multiply before subtracting/adding terms, like in this problem. Our main goal is to isolate c.
3a + 4b = (1 - 2c)/d (multiply both sides by d)
d(3a + 4b) = 1 - 2c (subtract 1 from both sides)
d(3a + 4b) - 1 = 2c (divide both sides by 2)
d(3a + 4b)/2 - 1/2 = c
We can simplify still this equation.
(3ad + 4bd)2 - 1/2 = c (distribute d)
3ad/2 + 4bd/2 - 1/2 = c (divide 3ad and 4bd by 2)
3ad/2 + 2bd - 1/2 = c (simplify)
Therefore, c is equal to 3ad/2 + 2bd - 1/2.
Final answer:
c = -d(3a + 4b - 1)/2
Explanation:
To solve for c in the equation 3a+4b=1-2c/d, rearrange the terms to isolate c, multiply both sides by d to eliminate the fraction, and then divide by -2.
To solve 3a+4b=1-2c/d for c, we will isolate the variable c by following these algebraic steps:
First, we need to move all the terms involving c to one side of the equation. The equation should look like this:3a + 4b - 1 = -2c/dNext, multiply both sides by d to get rid of the fraction:d(3a + 4b - 1) = -2cFinally, divide both sides by -2 to solve for c:c = -d(3a + 4b - 1) / 2This is how we derive the expression for c in terms of a, b, and d.

What is the value of k?
Answer:
k=2
Step-by-step explanation:
We have got a right triangle LNO with sides = m,4 and 8
By Pythagorean theorem
m^2=4^2 +8^2
Or m^2 = 80 ... i
IN triangle NOM, 4^2 +k^2 = l^2
i.e. 16+k^2 = l^2... i
In triangle LNM, m^2+l^2 = (8+k)^2
Substitute for m^2 as 80,
i.e. 80+l^2 = 64+k^2 +16k ... iii
From i, l^2 = 16+k^2
Substitute in iii
80+16+k^2 = 64+k^2 +16k
16k = 32 or k =2

You can represent this problem as a linear equation 100 + 20x = 175. Solving for x gives you 3.75, hence with $175, you can rent the jet ski for 3.75 hours.
Explanation:To solve this problem, you need to set up a linear equation. Let's represent the number of hours of the jet ski rental as x. The jet ski rental company charges a $100 rental fee plus $20 per hour, so we can write this as a equation: 100 + 20x = 175.
Next, we need to solve for x. First, subtract 100 from each side of the equation, you obtain 20x = 75. Then, divide each side by 20 to solve for x. You'll find that x = 3.75. Therefore, with $175, you can rent the jet ski for 3.75 hours.

Determine the domain of the function h(x)=9x/x(x^2-49)
Final answer:
The domain of the function h(x)=9x/x(x²-49) is all real numbers except for x = 0, x = -7, and x = 7, where the function is undefined due to division by zero. There are no additional nondifferentiable points within the domain, as the nondifferentiable points coincide with the excluded values.
Explanation:
To determine the domain of the function h(x)=9x/x(x^2-49), we need to identify all values of x for which the function is defined. Since this is a rational function, the function will be undefined where the denominator is zero. Thus, we set up the equation x(x² - 49) = 0 and solve for x.
First, factor the quadratic expression: x(x + 7)(x - 7) = 0. The solutions of this equation are x = 0, x = -7, and x = 7, which are the points where the function will be undefined.
Therefore, the domain of the function h(x) is all real numbers x except for x = 0, x = -7, and x = 7. These are the excluded values from the domain because they make the denominator equal to zero, which would result in division by zero.
Nondifferentiable Points
Aside from the excluded values, there may also be nondifferentiable points within the domain where the derivative does not exist or is not continuous. However, since all nondifferentiable points in this case coincide with the excluded values (the points where the denominator is zero), there will be no additional nondifferentiable points within the domain of the function.

In a recent year a baseball team paid two times as much to their ace pitcher as they paid to their shortstop. If they paid $21 million for the two salaries, what did they pay each player?
The ace pitcher was paid $14 million and the shortstop was paid $7 million.
Explanation:In order to solve this problem, we can set up a system of equations. Let's say the salary of the ace pitcher is x million dollars and the salary of the shortstop is y million dollars. We are given that the ace pitcher was paid twice as much as the shortstop, so we can set up the equation x = 2y.
We also know that the total salaries paid were $21 million, so we can set up the equation
x + y = 21.
Using the first equation, we can substitute 2y for x in the second equation to get 2y + y = 21, which simplifies to 3y = 21. Dividing both sides by 3, we find that y = 7 million.
Substituting this value back into the first equation, we find that x = 2(7) = 14 million.
Therefore, the ace pitcher was paid $14 million and the shortstop was paid $7 million.

Windless Surfing Company’s marketing manager observes that if the price of designer windsocks is $40, then on average 70 windsocks are sold per month. Experience has shown that if the price is raised from $40, then for every $1 increase in price, two fewer windsocks are sold each month.
Answer:
The answer is x ≤ 50.
Step-by-step explanation:
As, A -70 = -2 (P -40)
A = -2P + 80 + 70
A = -2P + 150
Y = -2x + 150.
When y = 0,

how do you decide whick of two numbers is greater when both numbers are positive,both numbers ate negative, and one number is positive and one number is negative
Final answer:
To compare two numbers, understand that positive numbers are greater than negative ones, among positives or negatives, larger numerical values determine greatness, and among two negatives, those closer to zero are greater.
Explanation:
Comparing two numbers to decide which is greater involves understanding their signs and values. Here's how you can determine this:
If both numbers are positive, the one with the higher numerical value is greater. For example, between 3 and 5, 5 is greater because 3 < 5.If both numbers are negative, the one with the lower absolute value is greater because it is closer to zero. For example, between -4 and -2, -2 is greater because -4 < -2.If one number is positive and the other is negative, the positive number is always greater than the negative one. This is because positive numbers are always to the right of negative numbers on the number line, indicating they are greater.Remember, the key to comparing numbers is understanding the role of positive and negative signs and the numerical value of the numbers.

The area of a rectangle is 48 square feet, If the perimeter is 32 feet, find the length and width of the rectangle
the length totals out to 12ft and the width totals out to 4ft.
To find the length and width of the rectangle, set up a system of equations using the given information. Solve for one variable in terms of the other using the equation for the area. Substitute the value of one variable into the equation for the perimeter. Solve the resulting quadratic equation to find the possible values for the width. Choose the appropriate positive value for width and find the corresponding length using the equation for the area.
Explanation:To find the length and width of the rectangle, we need to set up a system of equations using the given information. Let's represent the length as 'l' and the width as 'w'. We know that the area of a rectangle is given by the formula A = lw, and the perimeter is given by the formula P = 2(l + w).
Given that the area is 48 square feet and the perimeter is 32 feet, we can set up the following equations:
A = lw = 48P = 2(l + w) = 32From equation (1), we can solve for one variable in terms of the other. Let's solve for 'l':
l = 48/w
Now, substitute this value for 'l' in equation (2):
32 = 2(48/w + w)
Simplifying further:
16 = 48/w + w
Multiply both sides of the equation by 'w' to eliminate the fraction:
16w = 48 + w^2
Rearrange the equation:
w^2 + 16w - 48 = 0
Factoring the quadratic equation, we get:
(w + 8)(w - 6) = 0
Therefore, the possible values for 'w' are -8 and 6. Since width cannot be negative, we discard the -8 and conclude that the width is 6 feet.
To find the length, substitute the width value of 6 into equation (1):
l = 48/6 = 8 feet
Therefore, the length of the rectangle is 8 feet and the width is 6 feet.
Dario bakes a lasagna containing 2/3 pound of parmesan cheese, 5/4 pounds of ricotta cheese, and 4/3 pounds of mozzarella cheese. Dario cuts the lasagna into several equal slices, each containing exactly 1/4 pound of cheeses (of all types totalled). How many slices are there?
Dario could make 9 slices of lasagna with the provided amount of cheese, as each slice contains 1/4 pound of cheese and he has a total of roughly 2.33 pounds of cheese.
Explanation:To answer this question, we first need to calculate the total weight of the cheese used in the lasagna. This consists of 2/3 pound of parmesan cheese, 5/4 pounds of ricotta cheese, and 4/3 pounds of mozzarella cheese. To total these up, we convert them into fractions with a common denominator. Doing this, we find that, in total, 28/12 or approximately 2.33 pounds of cheese are used. As each slice of lasagna contains 1/4 pound of cheese, we can determine the total number of slices by dividing the total weight of the cheese by the weight of the cheese in each slice. This gives us: 2.33 ÷ 0.25 = 9.32. As we can't have a fractional number of slices, we round down to get 9 slices, which would be the amount of lasagna slices Dario could make with the provided amount of cheese.
