Answers
The solution to the given equation 3/7 divided by 11/21 = (3/7)x is x = 21/11.
What is the solution to the given equation?Given the equation in the question;
3/7 divided by 11/21 = 3/7 x
3/7 ÷ 11/21 = (3/7)x
To divide two fractions, multiply the first fraction by the reciprocal of the second fraction.

3/7 × 21/11 = (3/7)x
( 3 × 21 )/( 7 × 11 ) = (3/7)x
63/77 = (3/7)x
Remove the parenthesis
63/77 = (3/7) × x/1
63/77 = ( 3 × x )/( 7 × 1)

Caroline is the youngest of four siblings whose ages are consecutive odd integers. If the sum of their ages is 9696, find Caroline's age.
Answers
Answer:
2421 or 21
Step-by-step explanation:
Hello!
Consecutive odd integers are set of odd integers that come right after each other.
Let "C" be Caroline's age. Caroline's next older sibling would be C + 2, as odd integers come to every two numbers, and the next would be C + 4, and finally C + 6.
If we add up all the expressions, we should get 9696.
Solve for CC + C + 2 + C + 4 + C + 6 = 96964C + 12 = 96964C = 9684C = 2421The solution to this question does not seem reasonable. I assume that the correct sum of the age should be 96, given 9696.
If this is the case, then Caroline's age would be 21, using the same general logic.

You find 400 mg of a substance that has a half-life of 20 days. What is it's daily rate of decay? Round answers to four decimal places.
Answers
The daily rate of decay is approximately equal to 0.0347 days⁻¹.
What is the rate of decay of a substance?
According to the statement, we find that a substance is under a decay process, whose differential equation is introduced below:
dm(t) / dt = - k · m(t) (1)
Where:
m(t) - Current mass of a substance, in miligrams.k - Rate of decay, in 1 / day.The half-life of the substance is the time needed for a substance to decrease its mass by half. The rate of decay can be found in terms of half-life:
k = (㏑ 2) / t' (2)
Then, the daily rate of decay of the substance is:
k = (㏑ 2) / (20 days)

We create a number line with a range from 0 to 1.0 and divide it into 5 equal segments to demonstrate the equality between 0.200 and 1/5.
What is a Number Line?The visual representation of numbers on a straight line, either horizontally or vertically, is known as a number line. When numbers are written down on a number line, it is straightforward for humans to compare them and perform basic arithmetic operations on them. One might assume that a number line starts at zero (0). There are only negative numbers to the left of zero and only positive numbers to the right of zero. In other words, as we move to the right on a number line, the value of the numbers increases. This shows that the numbers on the right are more numerous than those on the left.
We create a number line with a range from 0 to 1.0 and divide it into 5 equal segments to demonstrate the equality between 0.200 and 1/5.This line will include points at 0.2, 0.4, 0.6, 0.8, and 1.0.Next, we create a second number line that has five equally spaced segments and ranges from 0 to 5/5.This line will have the following points: 1, 2, 3, 5, 4, and 5/5.These values of 0.200 and 1/5 will be equivalent, as demonstrated by the equal segments.To know more about the number line, visit:

Answers
By elimination, the solution of the system of equations, 4x + 2y = 4 and 6x + 2y = 8, is (2 , -2).
A system of equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy all the equations.
There are three methods that can be used to solve system of equations.
1. Elimination
2. Substitution
3. Graphing
Using the elimination method, given two equations in x and y, a variable should be eliminated by adding/subtracting the two equations.
Subtracting the two equations will eliminate the variable y.
6x + 2y = 8 (equation 2)
4x + 2y = 4 (equation 1)
2x + 0y = 4
x = 2
Substitute the value of x to any of the two equations and solve for y.
6x + 2y = 8 (equation 2)
6(2) +2y = 8
2y = 8 - 12
2y = -4
y = -2

The arithmetic mean is the most straightforward and widely used method of calculating a mean or average. It only requires adding up a group of figures, then dividing the result by the entire amount of figures in the series. Consider the numbers 34, 44, 56, and 78 as an example. It totals 212.
The mean or arithmetic average are other names for the arithmetic mean. It is determined by adding up each number in a particular data set, then dividing the result by the overall number of items in the data set.

7-(-4) is 4 units from 7 in the negative direction.
The number line keeps going both ways. You can include 6, 7, and so on, all the way up to the hundreds, thousands, and beyond, because the set of natural numbers only extends to the right.
A number line is a diagram that shows numerical values along a straight line that can be drawn either horizontally or vertically. It's simple for us to compare and compute basic arithmetic operations on numbers when they are written down on a number line. A number line's origin is typically thought to be zero (zero). There are only positive numbers to the right of zero and only negative numbers to the left of zero.
therefore,

The area of a trapezoid is the total space covered by its sides. An interesting point to be noted here is that if we know the length of all sides we can simply split the trapezoid into smaller polygons like triangles and rectangles, find their area, and add them up to get the area of the trapezoid. However, there is a direct formula that is used to find the area of a trapezoid if we know certain dimensions.
Area of Trapezoid Formula :
The area of a trapezoid can be calculated if the length of its parallel sides and the distance (height) between them is given.
The formula for the area of a trapezoid is expressed as,

Answers
Using conversion, Beau can make 48 one-ounce bags of trail mix from the 3-pound trail mix he bought for the hike.
To know how much one-ounce bags of trail mix can he make from the 3-pound trail mix, convert first the amount of trail mix in pounds to ounce.
In mathematics, conversion is the process of changing the value of one form or unit to another. It can be changing ones unit of length, weight, volume or even currency to another.
Converting pounds to ounce,
1 pound = 16 ounces.
If Beau has 3 pounds of trail mix, equivalently, converting pounds to ounces, he has:
1 pound = 16 ounces
3 pounds = 3(16 ounces)
3 pounds = 48 ounces
If he wants to make one-ounce bag of trail mix from the 3-pound of trail mix (= 48 ounces), divide it by one ounce to get how many bags he can make.
number of one-ounce bag = 48 ounces/1 ounce
number of one-ounce bag = 48
