We know that 6 concrete broks weigh 90 kilograms so we can fin hoy much weigh each brok like this:
\(\frac{90}{6}=15\)Now we can complete the table with this factor so:
\(\begin{gathered} 1\to15 \\ 2\to30 \\ 3\to45 \\ 4\to60 \\ 5\to75 \\ 6\to90 \\ 7\to105 \end{gathered}\)the constant of proportionality will be:
\(k=\frac{y}{x}=\frac{105}{7}=15\)And the number next to the one will be 15 and that means that 1 brick weigh 15 kilograms

Step-by-step explanation:
5. Based on recent results, scores on the SAT test are normally distributed with a mean of 1511 and a standard deviation of 312. Scores on the ACT test are normally distributed with a mean of 21.1 and a standard deviation of 5.1. Assume that the two tests use different scales to measure the same aptitude. If someone gets an SAT score that is in the 95th percentile, find the actual SAT score and the equivalent ACT score.
Answers
Answer:
The actual SAT score is 2024.
The equivalent ACT score is 29.49.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
SAT score that is in the 95th percentile
Scores on the SAT test are normally distributed with a mean of 1511 and a standard deviation of 312, which means that \(\mu = 1511, \sigma = 312\)
95th percentile is X when Z has a pvalue of 0.95, so X when Z = 1.645. The score is:
\(Z = \frac{X - \mu}{\sigma}\)
\(1.645 = \frac{X - 1511}{312}\)
\(X - 1511 = 1.645*312\)
\(X = 2024\)
The actual SAT score is 2024.
Equivalent ACT score:
The equivalent ACT score is the 95th percentile of ACT scores.
Scores on the ACT test are normally distributed with a mean of 21.1 and a standard deviation of 5.1, which means that \(\mu = 21.1, \sigma = 5.1\). So
\(Z = \frac{X - \mu}{\sigma}\)
\(1.645 = \frac{X - 21.1}{5.1}\)
\(X - 21.1 = 1.645*5.1\)
\(X = 29.49\)
The equivalent ACT score is 29.49.

*A tree that is 3 feet tall is growing at a rate of 2 1/2 feet each year. A tree that is 6 feet tall is growing at a rate of 2 feet each year.
* Enter the number of years it will take the two trees to reach the same height.
Answers
Using Linear equations, In 6 years of time, both two trees reach the same height.
Linear equation:The concept used in this problem is the application of linear equations to find the number of years it will take for the two trees to reach the same height. To solve this problem using linear equations, we can assume the number of years as 'x' and form two linear expressions and solve them from 'x' i.e the number of years.
Here we have
A tree that is 3 feet tall and is growing at a rate of 2 1/2 feet each year.
Here 2 1/2 = 5/2 feet = 2.5 feet
A tree that is 6 feet tall is growing at a rate of 2 feet each year.
Let both trees reach the same height after 'x' years
The height of first tree= [ 3 + 2.5(x) ]
The height of the second tree = [ 6 + 2(x) ]
As we assumed both sides are equal
=> [ 3 + 2.5x ] = [ 6 + 2x ]
Subtract 3 from both sides
=> 3 - 3 + 2.5x = [ 6 - 3 + 2x ]
=> 2.5x = 2x + 3
Subtract 2x from both sides
=> 2.5x - 2x = 3
=> 0.5x = 3
Divide by 0.5 into both sides
=> 0.5x/0.5 = 3/0.5
=> x = 6
Therefore,
In 6 years of time, both two trees reach the same height.

Select a personal or professional example of a measurement you use routinely. Convert the measurement either from U.S customary units to metric units, or from metric units to U.S. customary units. You may choose more than one measurement and may choose among weight, length, temperature, etc. Show each step of your conversion and be sure to include all units from the original and converted measurements (for example, yards to meters, degrees Celsius to degrees Fahrenheit).
Answers
A personal example of a measurement I use routinely is converting weight from U.S. customary units to metric units. Let's convert pounds to kilograms.
To convert pounds to kilograms, we use the conversion factor of 1 pound = 0.453592 kilograms.
For example, if I have a weight of 150 pounds, I can calculate the equivalent weight in kilograms as follows:
150 pounds * 0.453592 kilograms/pound = 68.0388 kilograms
Therefore, 150 pounds is approximately equal to 68.0388 kilograms.
In this conversion, we multiply the weight in pounds by the conversion factor to obtain the weight in kilograms. By using the appropriate conversion factor, we can accurately convert weights from U.S. customary units to metric units.
It's important to note that conversion factors may vary slightly depending on the rounding used and the exact value of the conversion factor.

The two numbers whose sum is 25 and product is 136 are 17 and 8
What is simultaneous equation?
Simultaneous equations are equations whose unknown values are determined together because the equations are dependent.
In this case, we assume the two number are X and Y, which means X plus Y is 25
X+Y=25 .........(equation 1)
In the same vein, the product of X and Y is 136
XY=136 ......(equation 2)
In equation 1, we can make X the subject
X=25-Y
Let us substitute for the value of X in equation 2
(25-Y)*Y=136
25Y-Y^2=136
Y^2-25Y+136=0

Keller Construction is considering two new investments. Project E calls for the purchase of earthmoving equipment. Project H represents an investment in a hydraulic lift. Keller wishes to use a net present value profile in comparing the projects. The investment and cash flow patterns are as follows: Use Appendix B for an approximate answer but calculate your final answer using the formula and financial calculator methods.
Answers
Based on the net present value profile, Project H has a higher NPV than Project E.
To compare the net present value (NPV) of Project E and Project H, we need to calculate the present value of cash flows for each project and determine which one has a higher NPV. The cash flow patterns for the two projects are as follows:
Project E:
Initial investment: -$100,000
Cash flows for Year 1: $40,000
Cash flows for Year 2: $50,000
Cash flows for Year 3: $60,000
Project H:
Initial investment: -$120,000
Cash flows for Year 1: $60,000
Cash flows for Year 2: $50,000
Cash flows for Year 3: $40,000
To calculate the present value of cash flows, we need to discount them using an appropriate discount rate. The discount rate represents the required rate of return or the cost of capital for the company. Let's assume a discount rate of 10%.
Using the formula method, we can calculate the present value (PV) of each cash flow and sum them up to obtain the NPV for each project:
For Project E:
PV = $40,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $60,000/(1 + 0.10)^3
PV = $36,363.64 + $41,322.31 + $45,454.55
PV = $123,140.50
For Project H:
PV = $60,000/(1 + 0.10)^1 + $50,000/(1 + 0.10)^2 + $40,000/(1 + 0.10)^3
PV = $54,545.45 + $41,322.31 + $30,251.14
PV = $126,118.90
Using the financial calculator method, we can input the cash flows and the discount rate to calculate the NPV directly. By entering the cash flows for each project and the discount rate of 10%, we find that the NPV for Project E is approximately $123,140.50 and the NPV for Project H is approximately $126,118.90.
