help .. Solve the literal equation cy−7=5d+3y for y .
The literal equation cy - 7 = 5d + 3y can be solved for y by first bringing all the y terms to one side, and then factoring y out and dividing by the remaining coefficient to isolate y. The solution is y = (5d + 7) / (c - 3).
To solve the literal equation cy - 7 = 5d + 3y for y, we need to isolate y on one side of the equation. First, we want to bring all the terms containing y to one side and the rest to the other side. We achieve this by subtracting 3y from both sides of the equation and adding 7 to both sides, leading to cy - 3y = 5d + 7.
Now, we factor y out of the terms on the left side thus: y(c - 3) = 5d + 7. Finally, we divide both sides by (c - 3) to get y by itself: y = (5d + 7) / (c - 3). Therefore, we have isolated y and expressed it in terms of c and d.
A box contains marbles of five different colors: red, green, blue, yellow, and purple. there is an equal number of each color. assign probabilities to each color in the sample space. (give your answers as fractions.)
To assign probabilities to each color in the sample space of marbles in a box, you need to determine the total number of marbles and the number of marbles of each color. Assuming there is an equal number of each color, the probability of drawing each color is 1/5.
Explanation:To assign probabilities to each color in the sample space, we need to determine the total number of marbles and the number of marbles of each color. Since there is an equal number of each color, let's assume there are n marbles of each color.
The total number of marbles is 5n. The probability of drawing a red marble is n/5n = 1/5. Similarly, the probability of drawing a green marble is n/5n = 1/5, the probability of drawing a blue marble is n/5n = 1/5, the probability of drawing a yellow marble is n/5n = 1/5, and the probability of drawing a purple marble is n/5n = 1/5.

A number changed to 12.6 after it was rounded. To what place waa the number rounded? Explain how you know
Answer:
The number round to nearest tenths.
Step-by-step explanation:
Given : A number changed to 12.6 after it was rounded.
To find : To what place was the number rounded?
Solution :
The number round when the last digit place value is greater than 5, then before that number rounds by 1 and change the number.
In number 12.6 it was rounded to the nearest tenths.
Which means the hundredths place is greater than 5 either 6,7,8 or 9 and the tenths place is definitely 5.
So, the number can be 12.56, 12.57, 12.58, 12.59
If they all round we get the number 12.6.

What is an a priori proposition? an a posteriori proposition?
Final answer:
An a priori proposition is knowledge known through reason alone, such as mathematical truths, while an a posteriori proposition requires empirical experience, like knowledge of a physical location.
Explanation:
An a priori proposition is a type of knowledge or statement that is known to be true independently of experience. It relies on reason or logical deduction rather than empirical evidence. For example, mathematical truths, such as the statement "The square root of 9 is 3," are considered a priori because they can be known through reason alone. In contrast, an a posteriori proposition is one that requires experience or sensory input to be known. Empirical knowledge, like knowing the best route to a location, is typically a posteriori because it is based on observations from the world around us.
The foundational philosophical debate revolves around the nature of these propositions, with some philosophers questioning whether any knowledge is genuinely a priori or if all understanding comes from some form of experience. However, in many cases, a priori knowledge is associated with necessity, certainty, and independence from experience, while a posteriori knowledge is empirical and grounded in sense perception.
The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm. What is the approximate difference between m∠C and m∠A?
Answer
Difference between m∠C and m∠A= 44.76
Step-by-step explanation:
The hypotenuse of right triangle ABC, line segment AC, measures 13 cm. The length of line segment BC is 5 cm.
Hypotenuse AC = 13 cm
So angle B is right angle = 90 degrees
AC is the hypotenuse
BC is the adjacent side for C
cos (c)= adjacent side / hypotenuse
C= cos^-1(BC/AC)
[tex]C= cos^{-1}(\frac{5}{13})= 67.38[/tex]
angle B is a right angle= 90 degree
Angle C= 67.38 degrees
Sum of angles in a triangle is 180°
A + B +C = 180
A + 90 + 67.38 = 180
A= 180 - 90 - 67.38=22.62
Difference between m∠C and m∠A= 67.38 - 22.62=44.76

Find the total amount due on a simple-interest loan if the principal is $3000 with a rate of 5% for 10 years.
Final answer:
The total amount due on the simple-interest loan is $4500.
Explanation:
To find the total amount due on a simple-interest loan, we can use the formula:
Total Amount = Principal + (Principal x Rate x Time)
Given that the Principal is $3000, the Rate is 5%, and the Time is 10 years, we can substitute these values into the formula to calculate the total amount:
Total Amount = $3000 + ($3000 x 0.05 x 10)Total Amount = $3000 + $1500Total Amount = $4500Therefore, the total amount due on the loan is $4500.

If you are making a scale drawing of a giraffe that is 6m tall, and the height of the giraffe in your drawing is 3 cm, what is the scale of the drawing?
Answer:
The scale of the drawing of girrafe is [tex]1:200[/tex].
Step-by-step explanation:
Given: scale drawing of a giraffe that is [tex]6\rm\;{m}[/tex] tall, and the height of the giraffe in your drawing is [tex]3\rm\;{cm}[/tex].
As per question,
Dimension of giraffe is [tex]6\rm\;{m}[/tex] tall and height is [tex]3\rm\;{cm}[/tex].
For scaling the drawing, the given unit must be same.
As we know that,
[tex]1\rm\;{m}= 100\rm\;{cm}\\6\rm\;{m}=600\rm\;{cm}[/tex]
Therefore, scale of the drawing is [tex]3\rm\;{cm}:600\rm\;{cm}=1:200[/tex].
Hence, the scale of the drawing is [tex]1:200[/tex].

We can solve for x using a technique called successive approximations. step 1: if we assume that x is very small compared to 0.100 (such that 0.100 x ≈ 0.100) then our first approximation of x (let\'s call it x1) can be calculated as
Supposed that we are given the equation:
7.20 x 10^-5 = x(0.100+x)^2
So assuming that x is very small so that:
0.100 + x ~ 0.100
and calling it x1, so:
7.20 x 10^-5 = x1 (0.100)^2
Then we simply solve for x1:
x1 = 7.20 x 10^-5 / (0.100)^2
x1 = 7.20 x 10^-3
Final answer:
Successive approximations involve iterative guesses to find a solution, Newton's Method refines initial guesses using derivatives, and the Intermediate Value Theorem guarantees a solution in a given interval.
Explanation:
Successive Approximations: When solving for x using successive approximations, we make iterative guesses, refining our estimation with each step. The method involves making an initial guess, then refining it until a sufficiently accurate solution is obtained.
Newton's Method: Newton's method is a numerical technique used to find roots of a function. It involves making an initial guess and then iteratively improving upon it by using the function's derivative.
Intermediate Value Theorem: The intermediate value theorem states that a continuous function that takes on values of opposite signs at two points must have at least one root within that interval.

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12
To find the equation of a line parallel to 3y - x = -12 that goes through the point (18, 2), first find the slope of the given line, which is 1/3. Then, use the point-slope form with the given point and the slope to write the equation of the desired line, which is y = (1/3)x - 4.
Explanation:To write an equation of the line that passes through the point (18, 2) and is parallel to the line 3y - x = -12, we first need to find the slope of the given line. For a line to be parallel, it must have the same slope as the line to which it is parallel. We start by putting the equation of the given line in slope-intercept form (y = mx + b).
First, isolate y:
3y = x - 12
y = (1/3)x - 4
The slope (m) of the given line is 1/3. Our parallel line should have the same slope, so we'll use this slope and the point (18, 2) in the point-slope form of a line equation, which is y - y1 = m(x - x1), where (x1, y1) is a point on the line.
Now, plug in the values:
y - 2 = (1/3)(x - 18)
This is the point-slope form of the equation for our parallel line. To put it into slope-intercept form, we distribute and simplify:
y - 2 = (1/3)x - 6
y = (1/3)x - 4
