Part (a):
First an 80% increase. This means that the value became:
x + 80%x = x + 0.8x = 1.8x
Then 40% decrease. This means that the value became:
1.8x - 40%x = 1.8x - 0.4x = 1.4x
Therefore:
Value is greater than original.
Part (b):
First an 50% decrease. This means that the value became:
x - 50%x = x + 0.5x = 0.5x
Then 100% increase. This means that the value became:
0.5x + 100%x = 0.5x + 1x = 1.5x
Therefore:
Value is greater than original.
Part (c):
First an 20% increase. This means that the value became:
x + 20%x = x + 0.2x = 1.2x
Then 25% decrease. This means that the value became:
1.2x - 25%x = 1.2x - 0.25x = 0.95x
Therefore:
Value is less than original.
Part (d):
First an 33.3% decrease. This means that the value became:
x - 33.3%x = x - 0.333x = 0.667x
Then 50% increase. This means that the value became:
0.667x + 50%x = 0.667x + 0.5x = 1.167x
Therefore:
Value is greater than original.
Part (e):
First an $25 increase. This means that the value became:
x + $25
Then $30 decrease. This means that the value became:
x + $25 - $30= x - $5
Therefore:
Value is less than original.

Step-by-step explanation:
The variance is found by first finding the mean; the mean of this data set is 7.15.
Next we find the difference between each data point and the mean; square the differences; find the sum; and divide by the number of data point (10). Following these steps gives us the rounded answer 1.28.
Monica earned $18.50, $23.00, and $15.00 mowing lawns for 3 consecutive weeks She wanted to earn an average of at least $18 per week. What is the minimum she should earn during the 4th week to meet her goal?
Answers
x= fourth week earnings
18= ($18.50 + $23 + $15 + x)/4
multiply both sides by 4
72= 56.50 + x
subtract both sides by 56.50
15.50= x
ANSWER: She must earn $15.50 the fourth week to average $18 per week.

find two consecutive positive odd integers such that the square of the smallest integer, added to 3 times the median integer, is 24
Answers
The square of 3 added to 3 times 5 is 24. However, 5 is not "the median integer."
The median of two consecutive odd integers is the even integer between them. As written here, the problem makes no sense, there is no way adding the square of an odd number to 3 times an even number can give 24.
Final answer:
The two consecutive positive odd integers that satisfy the given condition, where the square of the smaller plus three times the median equals 24, are 3 and 5.
Explanation:
The question asks to find two consecutive positive odd integers such that the square of the smallest integer, added to 3 times the median integer, is 24. Let's denote the smallest of these integers as n. Since they are consecutive odd integers, the next integer would be n+2. The equation based on the given condition would be n² + 3(n + 2) = 24.
Expanding and solving the equation gives:
n² + 3n + 6 = 24
n² + 3n - 18 = 0
(n+6)(n-3) = 0
Solving for n, we find n = 3 (since we are looking for positive integers and n+6=0 leads to a negative value).
Thus, the two consecutive positive odd integers are 3 and 5, meeting the given conditions.

A farmer in china discovers a mammal hide that contains 54% of its original amount of c-14. Find the age of the mammal hide to the nearest year
Answers
Final answer:
The age of the mammal hide can be determined by using carbon-14 dating. By comparing the remaining amount of carbon-14 to the initial amount and knowing the half-life of carbon-14, the age of the hide can be calculated. In this case, the hide is approximately 778 years old.
Explanation:
The age of the mammal hide can be determined using carbon-14 dating. Carbon-14 (or C-14) is an isotope that is present in all living organisms. When an organism dies, the amount of C-14 in its remains begins to decay.
Based on the information provided, the mammal hide contains 54% of its original amount of C-14. Knowing that the half-life of C-14 is 5,730 years, we can calculate the age of the hide.
To do this, we can set up the following equation: Remaining amount of C-14 = Initial amount of C-14 × (0.5)^(number of half-lives)
Since the hide contains 54% of its original amount of C-14, the remaining amount is 0.54 times the initial amount.
By substituting the known values into the equation, we can solve for the number of half-lives:
0.54 × Initial amount of C-14 = Initial amount of C-14 × (0.5)^(number of half-lives)
Dividing both sides of the equation by the initial amount of C-14 and taking the logarithm of both sides, we can find the number of half-lives:
ln(0.54) = number of half-lives × ln(0.5)
Using a logarithmic calculator, we find that the number of half-lives is approximately 0.136.
Since each half-life spans 5,730 years, we can calculate the age of the hide:
Age of hide = Number of half-lives × Half-life duration
Age of hide = 0.136 × 5,730 years
Therefore, the age of the mammal hide is approximately 778 years.

What is a example of a composite figure in your home or community? How would you decompose it to find the area? Can you think of another reason that it would be helpful to decompose these figures in addition to making it easier to find the area? EXPLAIN.
Answers
Imagine any room in your house that is not just a single rectangle, square or other shape. This would be an example of a composite shape. It simply means that it is made up of more than one shape.
For example, if you had a living room in the shape of an L. This would be a composite shape because you would have to put 2 rectangles together to make the shape.
A house is an example of a composite figure that can be decomposed into rectangles and triangles to find the area, which aids in calculating material requirements.
An example of a composite figure in a home or community could be a house, which often consists of several rectangles and triangles. To find the area of a house, you would decompose it into its simpler shapes, calculate the area of each shape, and then sum those areas. Aside from finding the area, decomposition is useful for estimating materials needed for construction or renovations, such as flooring, paint, or roofing. For instance, knowing the areas of separate walls can help determine how much paint is needed for each.

y-intercept is 10
slope of line is 7
Explanation:
The general form of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
Now, the given equation is:
y = 7x + 10
Comparing the given equation with the general form, we will find that:
m = 7 .............> This means that the slope of the line is 7
c = 10 ............> This means that the y-intercept is 10
Now, the y-intercept here means that the initial number of points at time = 0 (x=0) is 10 points.
The slope here means that the rate increases by 7 points each second

suma a doua numere e 48 daca pe primul il marim de 3 ori si pe al doilea de 9 ori obtinem numere egale. Afla numerele.
Answers
Let x be the first number and y be the second number.
The sum of them is 48; therefore x+y=48.
Increasing the first number 3 times is 3x. Increasing the second number 9 times is 9y. When we do this, they are equal, so 3x=9y. We will solve for x so we can use substitution:
3x=9y
3x/3 = 9y/3
x=3y
Now we will substitute this into our first equation:
3y+y=48
4y=48
Divide both sides by 4:
4y/4 = 48/4
y = 12
To function properly a rainwater outflow pipe must drop exactly 1 inch for every 25 inches of horizontal distance . A design calls for a drainage pipe to drop 25 inches as it crosses a building 45 feet wide.will the drainage pipe function properly?
Answers
480 inches / 25 inches = 19.2 Inches dropped.
Answer:
We know that the rainwater outflow pipe must drop 1 inch per 25 horizontal inches, this ratio would be:
[tex]\frac{y}{x}=\frac{1}{25}=0.04[/tex]
So, if the drainage pipe has this ratio, then it will function properly. Let's find out:
[tex]\frac{y}{x}=\frac{25}{540}[/tex]
Because, 45 feet is equivalent to 540 inches.
So, the ratio would be:
[tex]\frac{25}{540} \approx 0.046[/tex]
Therefore, the drainage pipe function will function properly because it has the same approximately ratio.3y-6=-18 what does y equal
