Answer:
(C)
Step-by-step explanation:
If can't have a meaning as something can't decrease more than 100% of itself.
The statement that is meaningless is
There was a 120% decrease in the amount of water in a dam.
Option C is the correct answer.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
A percentage increase can be of any number.
A percentage decrease can not be below 100%.
Now,
A.
There was a 3% decrease in the price of sugar.
This is possible.
B.
There was a 200% increase in the population of the town.
This is possible.
C.
There was a 120% decrease in the amount of water in a dam.
This is not possible.
The highest percentage decrease can be up to 100%.
D.
There was a 0% change in the temperature in the room after 1 hour.
This is possible.
Thus,
There was a 120% decrease in the amount of water in a dam is meaningless.

Answer:
The ratio of side lengths is 4:15
The ratio of areas as a fraction is 16/225
Step-by-step explanation:
We can probably assume the triangles are similar. If that is the case, the smaller triangle is 4/15s the size of the blue triangle. That makes the ratio 4:15.
As for the ratio of areas, areas are expressed in length^2. Inches squared, centimeters squared, meters squared, or whatever length. It is always a length squared.
Similarly, the ratio of the length can be squared to give the ratio of the areas. The ratio of the areas is 4^2 / 15^2 = 16/225
You plan to retire in 30 years. After that, you need $75,000 per year for 20 years (first withdraw at t=31 ). At the end of these 20 years, you will enter a retirement home where you will stay for the rest of your life. As soon as you enter the retirement home, you will need to make a single payment of 2 million. You want to start saving in an account that pays you 8% interest p.a. Therefore, beginning from the end of the first year (t=1), you will make equal yearly deposits into this account for 30 years. You expect to receive $350,000 inheritance at t=30 from your late uncle and you will deposit this money to your retirement account. What should be the yearly deposits?
6587.25
7198.40
8066.36
8744.81
The yearly deposit needed to achieve the retirement goal is approximately $17,650.23. None of the given options match this amount, so the correct answer is not provided in the given options.
To calculate the yearly deposits needed, we can use the concept of future value of an annuity. The future value formula for an annuity is given by:
FV = P * [(1 + r)^n - 1] / r
Where:
FV = Future value of the annuity
P = Yearly deposit amount
r = Interest rate per period
n = Number of periods
In this case, the future value needed is $2 million, the interest rate is 8% (0.08), and the number of periods is 30 years. We need to solve for the yearly deposit amount (P).
Using the given formula:
2,000,000 = P * [(1 + 0.08)^30 - 1] / 0.08
Simplifying the equation:
2,000,000 = P * [1\(.08^3^0 -\) 1] / 0.08
2,000,000 = P * [10.063899 - 1] / 0.08
2,000,000 = P * 9.063899 / 0.08
Dividing both sides by 9.063899 / 0.08:
P = 2,000,000 / (9.063899 / 0.08)
P ≈ 2,000,000 / 113.298737
P ≈ 17,650.23
Therefore, the yearly deposit needed to achieve the retirement goal is approximately $17,650.23. None of the given options match this amount, so the correct answer is not provided in the given options.

a rational expression is undefined if the numerator is zero T/F
The given statement "a rational expression is undefined if the numerator is zero" is false because a rational expression is undefined if the denominator is zero, not the numerator.
When the denominator of a rational expression becomes zero, the expression becomes undefined because division by zero is not defined in mathematics.
If the numerator of a rational expression is zero, it does not make the expression undefined. Instead, it results in the value of the expression being zero, regardless of the value of the denominator.

Answer:
ADE = 63°
Step-by-step explanation:
One thing at a time. We can start telling that triangle ADE is isosceles, of baseAD. Means the two angles EAD e ADE are congruent, and each measures \(\frac {180-54}2 = 63°\).
Now look at angles EDA and ECB. They are corresponding angles relative to the parallels DA and CB, so they are congruent. Measure of angle C is the same of measure of angle ADE = 63°
Edit: I've been asked for the rest of the measures. Purple ones are the one you find during the exercize. Red ones are the remaining. External ADC is supplementary to ADC (it's an external angle) angle BAD is alternate to ADE respect to the two parallels AB and CE, so they are congruent. Angle ABC is supplementary to angle BCD since they're internal conjugate relative to the same two parallels.
A pillar is fixed in the centre of a circular meadow with diameter of 60 metres. The angle of elevation of its top was found to be 60%, when observed from a point of the circumference of circular meadow. Find the height of the pillar from the ground.
Answer:
17 meters
Step-by-step explanation:
|\ angle = 60 degrees here of triangle
| \ <-- digitaly drawn triangle
|___\
cirlcle diameter is 60 meters, since pillar is at the center then the distance of the pillar to the edge of the circlular meadow is (60/2) 30 meters.
30 meters is opposite of the angle.
The height of the pillar is adjacent to the angle so use tangent to solve
Tan(60) = 30/x
Tan(60) = 1.7; make sure that calculator is in degrees and not in radians to not get an incorrect value
1.7 = 30/x --> 1.7x = 30
x = 30/1.7
x = 17.3205 meters
using 2 significant figures gives us 17 meters
How many coins are in one pouch? Post the strategies you used to find the other number of coins in one pouch.
Answer:
6
Step-by-step explanation:
First, make an equation out of this diagram. Replace the coin pouches with the variable of x, and replace the number of coins with numerical values. You get the equation 2x + 21 = 5x + 3. Subtract 3 from both sides to get 2x + 18 = 5x. Then, subtract 2x from both sides to get 3x = 18. Divide both sides by 3 to get 6 coins per pouch.

Sides of a triangle are (x^2-1), (x^2+1) and 10cm. If the area of the triangle is 120cm^2, find x
If the area of the triangle is 120 cm^2, the value of x is equal to 6.
How to calculate the area of a triangle?Mathematically, the area of a triangle can be calculated by using this mathematical expression:
Area of a triangle (A) = 1/2 × b × h
Where:
b represents the base area of a triangle.h represents the height of a triangle.According to Hero's Formula area of triangle by Heron of Alexandria, if a, b, c are the side lengths of a triangle, then, the area of a triangle can be calculated by using this mathematical expression:
Area of a triangle (A) = √[s(s − a)(s − b)(s − c)]
Where:
s = (a + b + c)/2
s = (x + x + 1 + 2x - 1)/2
s = 4x/2
s = 2x
Substituting the parameters into Hero's Formula formula, we have the following;
x√10 = √[2x(2x − x)(2x − x - 1)(2x − 2x + 1)]
x√10 = x√2(x − 1)
√10 = √2(x − 1)
Taking the square of both sides, we have:
10 = 2(x - 1)
10 = 2x - 2
2x = 12
x = 12/2
x = 6.

a quadratic function f(x) is graphed in the xy-coordinate plane in which wuadrant eould the vertex of f (x+3)+2
Answer:
The vertex is located on the x-axis between the second and third quadrants
Step-by-step explanation:
Whereby the function is f(x) = (x + 3)², we have;
f(x) = (x + 3)² = x² + 6·x + 9
The vertex, (h, k), of the quadratic function given in general form, a·x² + b·x + c is found as follows;
h = -b/(2·a) and k = f(h)
Therefore by comparison of the given quadratic function and the general form of a quadratic function, we have;
a = 1, b = 6, c = 9
h = -6/(2 × 1) = -3
k = f(-3) = (-3)² + 6 × (-3) + 9 = 0
The vertex (h, k) = (-3, 0)
Therefore, the location of the vertex is on the x-axis axis between the second and the third quadrant.

18. A ferris wheel has a dimeter of 600 feet. It will tum clockwise continuously, completing a single rotation once every 36 minutes. Passengers board from a platform is 300 feed. Suppose you decide to ride this Ferris whell for two full tums, and that you hop on at time t=0. Let h(t) be your height above the ground, measured in feed. Remember that the notation h(t) means your height is a fuction of t, the number of minutes you have been riding. Sketch the graph of youre height from the ground as you ride the Ferris wheel for two rotations and find the equation.
17. For the equation y = 2 - sin(π/3 x + π/3), the amplitude is 1, the period is 6, and the phase shift is -1. 18. The equation representing your height above the ground, h(t), can be written as h(t) = 300 + 300 sin((π/18)t). The term 300 represents the mean height above the ground, and the sine function accounts for the oscillation of the Ferris wheel as time progresses
17. For the equation y = 2 - sin(π/3 x + π/3), the amplitude is 1, the period is 6, and the phase shift is -1. The amplitude represents the maximum distance from the mean value, which in this case is 2. The period is the length of one complete cycle of the function, and it is determined by the coefficient of x inside the sine function. The phase shift indicates the horizontal translation of the graph and is calculated by finding the value inside the parentheses that makes the argument of the sine function equal to zero.
18. The Ferris wheel has a diameter of 600 feet, so its radius is 300 feet. It completes one rotation every 36 minutes, which means it takes 18 minutes to reach its highest and lowest points. Since you decide to ride the Ferris wheel for two full rotations, your total ride time is 72 minutes. At time t = 0, you board the Ferris wheel. To sketch the graph of your height above the ground, h(t), we need to consider two periods of the Ferris wheel's rotation. During the first 36 minutes, your height will vary from 0 to 600 feet as you reach the highest and lowest points. Then, during the next 36 minutes, your height will again vary from 0 to 600 feet, completing the second rotation. The equation representing your height above the ground, h(t), can be written as h(t) = 300 + 300 sin((π/18)t). The term 300 represents the mean height above the ground, and the sine function accounts for the oscillation of the Ferris wheel as time progresses.

By investing in a particular stock, a person can make a profit of $4,000 in a year with probability 0.3 or take a loss of $1,000 with probability 0.7. What is this person's expected gain?
The person's expected gain from investing in this stock is $500.
The probability of earning a profit is given as 0.3, which means there is a 30% chance of this happening. The probability of taking a loss is given as 0.7, which means there is a 70% chance of this happening.
To calculate the expected gain, we need to multiply the probability of each outcome by its corresponding gain or loss. The expected gain is the sum of these products.
Expected gain = (probability of earning a profit x gain from earning a profit) + (probability of taking a loss x loss from taking a loss)
Expected gain = (0.3 x $4,000) + (0.7 x -$1,000)
