Sο the cοrrect οptiοn is: 12.94%.
What is the percentage decrease?Percentage decrease is the percentage by which a quantity οr value has decreased cοmpared tο its οriginal οr previοus value. It is calculated by taking the difference between the οriginal value and the new value, dividing that difference by the οriginal value, and then multiplying by 100 tο cοnvert the result intο a percentage. The fοrmula fοr percentage decrease is:
Percentage decrease = [(Original value - New value) / Original value] x 100%
The fοrmula fοr the amοunt οf radiοactive element remaining, r, in a 100-mg sample after d days is given as:
[tex]r = 100(1/2)^{(d/5)[/tex]
Tο find the daily percent οf decrease, we need tο find the difference between the amοunt οf the element at the start οf a day and the amοunt at the end οf that day, and then express this as a percentage οf the starting amοunt.
Let's assume that we start with 100 mg οf the radiοactive element. After οne day, the amοunt remaining is:
[tex]r = 100(1/2)^{(1/5)[/tex] ≈ 87.06 mg
The difference between the starting amοunt and the amοunt at the end οf the day is:
100 - 87.06 = 12.94
Tο express this as a percentage οf the starting amοunt, we divide this difference by the starting amοunt and multiply by 100:
12.94/100 * 100% = 12.94%
Therefοre, the daily percent οf decrease is 12.94%.

The inequality (x + 2)/(x - 7)>0 can be solved algebraically by first subtracting 2 from both sides. This results in the inequality (x - 7) > 2. By dividing both sides by (x-7), the inequality can be simplified to 1>2/x-7. This simplifies further to -7>2/x, or x>-7/2. Therefore, the solution to the inequality is x>-7/2.
In plain terms, this means that a value of x must be greater than -7/2 in order for the inequality to be true. This implies that the value of x must be a number greater than -3.5, since -7/2 is the same as -3.5. Thus, if x is any number greater than -3.5, then the inequality (x + 2)/(x - 7) > 0 will be satisfied.

Part A: Write an expression to represent the length of the rectangular space. Show all work to find the length
Length of Rectangular Space
Part B: Prove your answer from Part A is correct by multiplying the length and width of the rectangle.
Write the expression in standard form:
Answer:
Part A: To find the expression for the length of the rectangular space, we can use the formula for the area of a rectangle, which is length multiplied by width. We have the expression for the area as 8x² - 12x, and the expression for the width as 4x. So, we can write:
Area = Length × Width
8x² - 12x = Length × 4x
Simplifying the right side by multiplying, we get:
8x² - 12x = 4x × Length
2x² - 3x = Length
Therefore, the expression for the length of the rectangular space is 2x² - 3x.
Part B: To prove that the expression for the length from Part A is correct, we can multiply it by the expression for the width and simplify:
Length × Width = (2x² - 3x) × (4x)
= 8x³ - 12x²
= 4x(2x² - 3x)
= 4x(2x(x - 3))
This is in fact the same as the expression for the area of the rectangular space, 8x² - 12x, in standard form.

Krystal throws a rappelling rope at a speed of 10 m/s down a 50 m cliff.
When will the rope hit the ground?
Use the drop-down to put the correct order to solve for when the rope will hit the ground.
With speed = 10 m/s, the rope will hit ground after 3.36 seconds.
What exactly is speed?Speed is a measure of how fast an object is moving, usually measured in units of distance per unit time, such as meters per second (m/s) or kilometers per hour (km/h). It is a scalar quantity, meaning it only has magnitude and no direction.
Mathematically, speed is defined as the distance an object travels per unit time. The formula for calculating speed is:
Speed = Distance / Time
where Distance is the distance traveled by the object, and Time is the time taken to cover that distance.
Now,
To find when the rope will hit the ground, we can use the kinematic equation:
y = vi * t + (1/2) * a * t²
where:
y = 50 m (the height of the cliff)
vi = 10 m/s (the initial velocity of the rope)
a = 9.8 m/s² (the acceleration due to gravity, acting downward)
t = time it takes for the rope to hit the ground
We can solve for t by setting y=50 and solving for t:
50 = 10t + (1/2) * 9.8 * t²
50 = t(10 + 4.9t)
t = 50/14.9=3.36 s
Therefore, the rope will hit the ground after 3.36 seconds.

write an equation in point slope form for a line that passes through(-2,5) and (-1,1)
The equation of line is y = -4x - 3 and the slope is m = -4
What is an Equation of a line?The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of line be represented as A
Now , the value of A is
Let the first point be P ( -2 , 5 )
Let the second point be Q ( -1 , 1 )
Now , the slope of the line is m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values in the equation , we get
Slope m = ( 1 - 5 ) / ( -1 - ( -2 ) )
On simplifying , we get
Slope m = ( -4 ) / 1
Slope m = -4
Now , the equation of line is y - y₁ = m ( x - x₁ )
y - 5 = -4 ( x - ( -2 ) )
y - 5 = -4 ( x + 2 )
y - 5 = -4x - 8
Adding 5 on both sides , we get
y = -4x - 3
Hence , the equation of line is y = -4x - 3

Today, the sum of Caroline's age and Cameron's age is 73. 5 years ago Cameron was 2 times older than Caroline.
The answer of Caroline is 19.33 years old and Cameron is 53.67 years old
Let's start by assigning variables to represent Caroline's age and Cameron's age. We'll use C for Caroline's age and M for Cameron's age.
According to the problem, the sum of their ages today is 73, so we can write the equation:
C + M = 73
Five years ago, Cameron was 2 times older than Caroline. so we can write the equation:
M - 5 = 2(C - 5)
Now we can use the first equation to solve for one of the variables. Let's solve for C:
C = 73 - M
Next, we can substitute this value of C into the second equation:
M - 5 = 2(73 - M - 5)
Simplifying the equation gives us:
M - 5 = 146 - 2M - 10
3M = 161
M = 53.67
Now we can use this value of M to find C:
C = 73 - 53.67
C = 19.33
So Caroline is 19.33 years old and Cameron is 53.67 years old.

The two legs of a right triangle are 11 inches and 24 inches.
Find the hypotenuse of the triangle
To find the hypotenuse of a right triangle, we can use the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. The formula for the Pythagorean theorem is:
c^2 = a^2 + b^2
Where c is the hypotenuse, and a and b are the other two sides of the triangle.
In this case, we are given the lengths of the two legs of the triangle, 11 inches and 24 inches.
We can plug these values into the formula and solve for the hypotenuse:
c^2 = 11^2 + 24^2
c^2 = 121 + 576
c^2 = 697
c = √697
c ≈ 26.4 inches
Therefore, the hypotenuse of the triangle is approximately 26.4 inches.

If \( y \) varies directly as \( x \) and inversely as \( z \) and \( y=24 \) when \( x=120 \) and \( z=16 \), then what is the value of \( y \) when \( x=4 \) and \( z=15 \) ?
Y= 3.2
When \( y \) varies directly as \( x \) and inversely as \( z \), the equation is given by:
\( y = \frac{kx}{z} \)
Where \( k \) is a constant.
Substituting the given values of \( x \), \( y \) and \( z \), we get:
\( 24 = \frac{k(120)}{16} \)
Solving for \( k \):
\( k = \frac{24*16}{120} = 4.8 \)
Substituting the values of \( k \), \( x \) and \( z \) into the equation, we get:
\( y = \frac{(4.8)*4}{15} \)
Therefore, the value of \( y \) when \( x=4 \) and \( z=15 \) is \( 3.2 \).

At a grocery store, Ethan buys 4 bananas and 5 oranges for $5.60. The total cost of one banana and one orange is $1.20.
How much does each orange cost?
Answer:
The answer to your problem is, $0.60
Step-by-step explanation:
1 banana and 1 orange = 1.20.
We divide next:
1.20 / 2 = 0.60.
We know that because in the question it says one banana and one orange is 1.20. Next we divide because two items are sharing the same number.
1.20 / 2 = ? ( ? = 0.60 or 0.6 )
Thus the answer to our problem is, $0.60
According to a random sample taken at 12 A.M., body temperatures of healthy adults have a bell-shaped distribution with a mean of 98.33°F and a standard deviation of 0.67°F. Using Chebyshev's theorem, what do we know about the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean? What are the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean?
Question content area bottom
Part 1
At least enter your response here% of healthy adults have body temperatures within 2 standard deviations of 98.33°F
At least 75% of healthy adults have body temperatures within the range of 96.99°F to 99.67°F.
What is standard deviations?
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
Chebyshev's theorem states that for any distribution (not just the normal distribution), regardless of shape, at least 1 - 1/k^2 of the data values will be within k standard deviations of the mean, where k is any number greater than 1.
In this case, we want to know the percentage of healthy adults with body temperatures that are within 2 standard deviations of the mean. So we need to use Chebyshev's theorem with k = 2.
At least 1 - 1/2^2 = 1 - 1/4 = 0.75, or 75%, of the healthy adults have body temperatures within 2 standard deviations of the mean.
To find the minimum and maximum possible body temperatures that are within 2 standard deviations of the mean, we can use the formula:
Minimum = Mean - k * Standard deviation
Maximum = Mean + k * Standard deviation
Plugging in the values for this problem, we get:
Minimum = 98.33 - 2 * 0.67 = 96.99°F
Maximum = 98.33 + 2 * 0.67 = 99.67°F
Therefore, we can say that at least 75% of healthy adults have body temperatures within the range of 96.99°F to 99.67°F.
