Answer:
Number of logs:
1. 48
2. 14
3. 90
4. 48
5. 100
Total: 300
Step-by-step explanation:
Just multiply the height with the number of trees then divide by 6. This is in theory if the length of all the trees were conjoined, as there would most likely just be less, then 300. This is because the remainder would be that of the multiplied trees height instead of getting the remainder of wood from each tree. So in case you want to try doing that option, simply divide the height first in feet by 8, then multiply that by the number of trees to give you an accurate answer of logs.
Answer:
see attached
total: 300 logs
Step-by-step explanation:
When calculations are repetitive, it is convenient to let a spreadsheet do them.
Here, the number of logs per tree is found by dividing the tree height by 8 feet. The number of logs from trees that height will be found by multiplying the number of trees by the number of logs that height will give.
The total number of logs is the sum of the numbers from all the tree heights.

The total number of logs is 300. (The rightmost column of the attached spreadsheet matches the rightmost column of your table.)

The displacement of a 500 g mass, undergoing simple harmonic motion, is defined by the function :
x=-3.5sin(π/2t+(5π)/4)
Find
a. maximum kinetic energy
b. maximum potential energy
c. maximum mechanical energy
To solve this problem, we have to write out the simple harmonic motion equation and then use the respective formula to solve. The maximum kinetic energy, maximum potential energy and the maximum mechanical energy is equal to 7.56J.
Simple Harmonic MotionThe given equation of the simple harmonic motion is
[tex]x = 3.5sin(\frac{\pi}{2t} + \frac{5\pi}{4})\\[/tex]
Data;
ω = π/2k = 1.254N/mSolving this
[tex]\frac{dx}{dt} = \theta = -3.5 * \frac{\pi}{2} cos (\frac{\pi }{2}t + \frac{5\pi}{4})\\[/tex]
Let's calculate the maximum velocity.
[tex]V_m = \frac{3.5\pi}{2}[/tex]
This is only possible when cos θ = -1
The maximum kinetic energy is
[tex]K_m = \frac{1}{2}mv_m^2 = \frac{1}{2}* \frac{500}{1000} * (\frac{7\pi}{4} )^2\\K_m = 7.56J[/tex]
The maximum kinetic energy is 7.56J
The maximum potential energy can be calculated as
[tex]\omega^2 = \frac{k}{m} \\k = \omega^2 m \\k = \frac{\pi^2}{4} * \frac{500}{1000}\\ k= 1.254 N/m[/tex]
Using the value of spring constant, we can find the maximum potential energy
[tex]P.E = \frac{1}{2}kx^2\\P.E = \frac{1}{2} * 1.234 * 3.5^2\\P.E = 7.56J[/tex]
The maximum potential energy is 7.56J
The maximum mechanical energy is equal to the sum of maximum potential energy and the maximum kinetic energy.
[tex]ME = P.E + K.E\\ME = 7.56J[/tex]
The reason ME is equal to 7.56J is because when x is at maximum, v = 0 and makes kinetic energy equal to zero.
ME = 7.56J
From the calculations above, the maximum kinetic energy, maximum potential energy and the maximum mechanical energy is equal to 7.56J.

A jar contains 100 marbles. There are 7 blue marbles, 4 green marbles,
46 red marbles, and 43 yellow
marbles. What is the probability of
randomly selecting a yellow marble?
Enter the correct answer.
Answer:
43%
Step-by-step explanation:
If there are 43 yellow marbles out of 100 total, the fraction that will be used is 43/100. The percentage is found by dividing the numerator (top) by the denominator (bottom). The percentage is the first two numbers in the decimal. For future reference, if a decimal were to have more than 2 or 3 digits, the number would be rounded to the 4th and the decimal point would be placed between the 2nd and 3rd digits.
A manufacturer knows that their items have a normally distributed lifespan, with a mean of 11.5 years, and standard deviation of 1.9 years.
If you randomly purchase one item, what is the probability it will last longer than 12 years?
Answer:
39.74 %
Step-by-step explanation:
12 years - 11.5 = .5 years
.5 / 1.9 = .2631 S.D above the mean
From z-score table this corresponds to .6026
60.26 are BELOW this life span
39.74 % are above 12 years

What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
