Since a pelidisi below ( 100 ) is considered undernourished and a pelidisi greater than ( 100 ) indicates overfeeding, with a pelidisi of ( 114 ), this individual is considered to be overfed.
Let's denote the pelidisi as ( P ), the weight in grams as ( W ), and the sitting height in centimeters as ( H). According to the given information, the pelidisi varies directly as the cube root of the person's weight and inversely as the person's sitting height. This relationship can be expressed mathematically as:
[tex]\[ P = k \times \frac{\sqrt[3]{W}}{H} \][/tex]
where ( k ) is the constant of variation.
We are given that a person with a weight of ( 48,820 ) g and a sitting height of ( 78.7 ) cm has a pelidisi of ( 100 ). We can use this information to find the value of ( k ):
[tex]\[ 100 = k \times \frac{\sqrt[3]{48820}}{78.7} \][/tex]
Solving for \( k \):
[tex]\[ k = \frac{100 \times 78.7}{\sqrt[3]{48820}} \]\[ k \approx \frac{7870}{36} \approx 218.611 \][/tex]
Now that we have the value of \( k \), we can find the pelidisi for a person with a weight of \( 54,688 \) g and a sitting height of \( 72.6 \) cm:
[tex]\[ P = 218.611 \times \frac{\sqrt[3]{54688}}{72.6} \][/tex]
Calculating \( P \):
[tex]\[ P \approx 218.611 \times \frac{38}{72.6} \]\[ P \approx 218.611 \times 0.522 \]\[ P \approx 114.14 \][/tex]
Rounded to the nearest whole number, the pelidisi of a person with a weight of ( 54,688 ) g and a sitting height of ( 72.6 ) cm is ( 114 ).
Since a pelidisi below ( 100 ) is considered undernourished and a pelidisi greater than ( 100 ) indicates overfeeding, with a pelidisi of ( 114 ), this individual is considered to be overfed.
the hypotenuse of a right triangle is 24ft long. The length of one leg is 20ft more than the other. Find the length of the legs.
We can find the lengths of the legs of the right triangle using the Pythagorean theorem. One leg is x and the other leg is x+20. A quadratic equation can be solved to find x.
Explanation:The problem involves a right triangle, and we are given the length of the hypotenuse and a relationship between the lengths of the legs. We can solve it using the Pythagorean theorem, which for a right triangle with legs of lengths 'a' and 'b' and hypotenuse 'c' is stated as a² + b² = c².
Let's assign 'x' to the shorter leg. Given that the other leg is 20ft longer, it would be 'x + 20'. The hypotenuse is given as 24, hence the equation becomes: x² + (x + 20)² = 24².
By solving this equation, we find two potential values for 'x', but since a length can't be negative, we exclude the negative value. Hence, the length of the shorter leg is 'x' and of the longer leg is 'x + 20'.

Solve for t
The value of t in the simple interest formula P = Irt is t = P / (Ir).
To solve the simple interest formula P = Irt for t, we need to isolate the variable t on one side of the equation.
The formula can be rearranged as follows:
P = Irt
First, divide both sides of the equation by I:
P/I = rt
Next, divide both sides of the equation by r:
(P/I) / r = t
Simplifying further:
t = P / (Ir)
Therefore, the value of t in the simple interest formula P = Irt is t = P / (Ir).

What is 345,876 in short word form?
A baseball is hit with an initial upward velocity of 70 feet per second from a height of 4 feet above the ground. The equation h= −16t^2 +70t + 4 models the height in feet t seconds after it is hit. After the ball gets to its maximum height, it comes down and is caught by another player at a height of 6 feet above the ground. About how long after it was hit does it get caught?
By setting the given height (6 feet) in the height equation and using the quadratic formula to solve for time 't', we get two solutions. Since the ball reaches 6 feet twice in its ascension and decension, the latter value of t = 3.79 seconds would be the time it is caught.
Explanation:The question is regarding the time at which a baseball, hit with an initial upward velocity and caught at 6 feet above the ground, is caught. Firstly, input the given height of 6 feet into the height equation h= -16t^2 + 70t + 4 and solve for
t
. Based on the quadratic formula, we receive two solutions: t = 3.79 s and t = 0.54 s. Since the ball has two points at which it reaches the height of 6 feet during its trajectory - once while going up and once while coming down - the time when it is caught would be the larger value,
t = 3.79 s
. Therefore, approximately 3.79 seconds after being hit, the ball is caught.

Crystal reads 25 pages in 1/2 hours write an equation to represnets the relationship between the number of pages crystal reads and how much time she spends reading.
Crystal would read 37.5 pages in [tex]\( \frac{3}{4} \)[/tex] hour.
To represent the relationship between the number of pages Crystal reads and the time she spends reading, we can use the formula:
[tex]\[ \text{Pages Read} = \text{Reading Rate} \times \text{Time Spent Reading} \][/tex]
In this case, Crystal reads 25 pages in 1/2 hour, so her reading rate can be calculated as follows:
[tex]\[ \text{Reading Rate} = \frac{\text{Pages Read}}{\text{Time Spent Reading}} \][/tex]
[tex]\[ \text{Reading Rate} = \frac{25 \text{ pages}}{\frac{1}{2} \text{ hour}} \][/tex]
[tex]\[ \text{Reading Rate} = 25 \times 2 \][/tex]
[tex]\[ \text{Reading Rate} = 50 \text{ pages per hour} \][/tex]
Now, we can substitute this reading rate into the equation to represent the relationship:
[tex]\[ \text{Pages Read} = 50 \times \text{Time Spent Reading} \][/tex]
This equation describes the relationship between the number of pages Crystal reads and the time she spends reading.
To illustrate how to use this equation, let's say Crystal reads for [tex]\( \frac{3}{4} \)[/tex] hour. We can plug this value into the equation to find out how many pages she reads:
[tex]\[ \text{Pages Read} = 50 \times \frac{3}{4} \][/tex]
[tex]\[ \text{Pages Read} = 37.5 \][/tex]
So, Crystal would read 37.5 pages in [tex]\( \frac{3}{4} \)[/tex] hour.

A store stocked 150 cans of popcorn for a weekend sale.
That weekend, 72 of the cans sold. What percent of the
cans of popcorn stocked were sold that weekend?
Answer:
48%
Step-by-step explanation:
In order to find the percentage we need to divide the sold cans by total cans and multiply the result by 100.
Total cans = 150
Sold cans = 72
→ 72/150 = 0.48
→ 0.48 * 100 = 48
The percentage of the cans of popcorn stocked were sold that weekend is 48%
The given parameters are:
Total can of popcorn = 150
Sold can of popcorn = 72
The percentage of can sold is then calculated as:
[tex]\%Sold = \frac{72}{150} *100\%[/tex]
Multiply 72 and 100
[tex]\%Sold = \frac{7200}{150}\%[/tex]
Divide 7200 by 150
[tex]\%Sold = \%48[/tex]
Hence, the percentage of the cans of popcorn stocked were sold that weekend is 48%

What effect does adding a constant have on a exponential function?
Adding a constant to an exponential function results in shifting the graph vertically or horizontally, depending on where the constant is added. The shift will be positive for a positive constant and negative for a negative constant.
Explanation:In Mathematics, when dealing with an exponential function, adding a constant can affect the function in two different ways, depending on where the constant is being added. If the constant is added to the exponent, this results in shifting the graph horizontally. However, if the constant is added outside the exponent (as in f(x) = 2x + k), this will result in the entire graph being shifted upward or downward vertically, based on whether the constant is positive or negative.
For example, consider the simple exponential function f(x) = 2x. If a constant 'c' is added - resulting in f(x) = 2x + c, the resulting graph will be the same as the original, but shifted 'c' units upward if 'c' is positive and downward if 'c' is negative. This is a fundamental principle of exponential functions.

On average, the merchandise shop sells 80 CDs for every 1 vinyl record. Estimate how many vinyl records they are likely to sell if the merchandise shop sells 760 CDs.
Answer:
10 vinyl records are expected to be sold.
Step-by-step explanation:
On average, the merchandise shop sells 80 CDs per 1 vinyl record. This is our conversion factor. To estimate the number of vinyl records likely to be sold when 760 CDs have been sold we will use proportions.
760 CD × (1 vinyl record/ 80 CD) = 9.5 ≈ 10 (we round it off because you cannot sell half a vinyl record).
10 vinyl records are expected to be sold.

A mother gives birth to a 10 pound baby. Every 4 months, the baby gains 2 pounds. If x is the age of the baby in months, then y is the weight of the baby in pounds. Find an equation of a line in the form y = mx + b that describes the baby's weight.
The equation of the line that describes the baby's weight is y = (1/2)x + 10.
Explanation:To find the equation of the line that describes the baby's weight, we need to determine the slope and y-intercept of the line. The slope represents the rate at which the baby's weight increases, and the y-intercept represents the initial weight of the baby.
Since the baby gains 2 pounds every 4 months, the slope of the line is 2/4 = 1/2. This means that for every month that passes, the baby's weight increases by 1/2 pound.
To find the y-intercept, we can use the initial weight of the baby, which is 10 pounds. So the equation of the line is y = (1/2)x + 10.

∫∫A) | r(u) *r( v) | dudv
The solution is:
A = 10.35×π square units
r ( u , v ) = u×cosv i + u×sinv j +v k
To get
r (u ) = δ(r ( u , v ) ) / δu = [ cosv , sinv , 0 ]
r ( v ) = δ(r ( u , v ) ) / δv = [ -u×sinv , u×cosv , 1 ]
The vectorial product is:
i j k
r (u ) * r ( v ) cosv sinv 0
-u×sinv u×cosv 1
r (u ) * r ( v ) = i × ( sinv - 0 ) - j × ( cosv - 0 ) + k ( u×cos²v + u× sin²v )
r (u ) * r ( v ) = sinv i - cosv j + u k
Now
| r (u ) * r ( v ) | = √sin²v + cos²v + u² = √ 1 + u²
Then
A = ∫₀ (9π) dv ∫₀¹ √ 1 + u² du
∫₀¹ √ 1 + u² du = 1.15
A = 1.15 × v |( 0 , 9π )
A = 10.35×π square units

A sealed rectangle or box measuring 8 x 6 x 18 contains 864 Sugar cubes each measuring one by one by one how many sugar cubes are touching the box
The arrangement of the 864 cubes would be 18 6 by 8 layers.
All 48 would be touching the bottom of the box on the bottom layer and all 48 would be touching the top of the box on the top layer.
The cubes along both lengths would be touching the sides of the box for the remaining 16 layers. That would be16 cubes per layer or 256 cubes after counting both sides.
The cubes along the width would be touching the ends of the box for those 16 layers. Those need to be eliminated from the count since the corner cubes were already counted as part of the ones touching the sides. 4 cubes have not been previously counted for each width of 6 cubes. Both ends of the 16 layers has 8 cubes per layer or 128 cubes.
Therefore, that is 256 (sides) + 128 (ends) + 48 (top) + 48 (bottom) and that totals to 480 cubes touching the box.
