A pottery factory purchases a continuous belt conveyor kiln for $68,000. A 6.3% APR loan with monthly payments is taken out to purchase the kiln. If the monthly payments are $765.22, over what term is this loan being paid?
Answers
Based om the cost of the continuous belt conveyor kiln and the monthly payments, as well as the APR of the loan, the term this loan will be paid is 120 months or 10 years.
How to find the term of the loan?When given the cost of a loan, the APR, and the monthly payments, you can find out the term of the loan by using the NPER function on a spreadsheet.
The Rate would be:
= 6.3% / 12 months in a year
= 0.525%
The Pmt is the payment of $765.22. This amount should be in negatives.
The Present Value or Pv should be the loan amount of $68,000.
The term on the loan would then be 120 months which is 10 years.

If the time to climb the mountain took an hour more than the time to hike down how long was entire hike?
Answers
4.8 mi
Explanation
[tex]\text{time}=\text{ }\frac{\text{distance}}{\text{rate}}[/tex]
Step 1
Set the equations
a) uphill
let
rate1= 1.5 miles per hour
time= unknow= t1
distance = x
b) down hille
rate=4 miles per hour
time=time2=one hour less than the time to climb = t1-1
distance = x
so
replacing
[tex]\begin{gathered} t_1=\frac{x}{1.5\frac{mi}{\text{hour}}}\rightarrow t_1=\frac{x}{1.5}\rightarrow equation(1) \\ t_2=\frac{x}{4\frac{mi}{\text{hour}}} \\ \text{replace t}_2=t_1-1 \\ t_1-1=\frac{x}{4} \\ \text{add 1 in both sides} \\ t_1-1+1=\frac{x}{4}+1 \\ t_1=\frac{x}{4}+1\rightarrow equation(2) \end{gathered}[/tex]Step 2
solve the equations
[tex]\begin{gathered} t_1=\frac{x}{1.5}\rightarrow equation(1) \\ t_1=\frac{x}{4}+1\rightarrow equation(2) \end{gathered}[/tex]set t1= t1
[tex]\begin{gathered} t_1=t_1 \\ \frac{x}{1.5}=\frac{x}{4}+1 \\ \frac{x}{1.5}=\frac{x+4}{4} \\ 4x=(x+4)1.5 \\ 4x=1.5x+6 \\ subtract\text{ 1.5 x in both sides} \\ 4x-1.5x=1.5x+6-1.5x \\ 2.5x=6 \\ \text{divide both sides by 2.5} \\ \frac{2.5x}{2.5}=\frac{6}{2.5} \\ x=2.4 \end{gathered}[/tex]it means the distance to the top of the mountain is 2.4 miles, so the entire hike is twice that amount
total distance=2.4 mi*2
total distance=4.8 miles
Step 3
now, the times
[tex]\begin{gathered} t_1=\frac{x}{1.5} \\ t_1=\frac{2.4}{1.5} \\ t_1=1.6\text{ hours} \\ t_2=t_1-1 \\ t_2=1.6-1=\text{ 0.6 hours} \end{gathered}[/tex]table

The total net operating income (NOI) of both divisions is $1,03,500.
What is net operating income?Real estate professionals use the formula known as Net Operating Income, or NOI, to quickly determine the profitability of a specific investment. After deducting required operating costs, NOI calculates the revenue and profitability of investment real estate property. Let's say, for illustration purposes, that you own a duplex with a gross monthly income of $2,000 and monthly operating expenses of $400. You would start with your annual gross income ($24,000) and deduct your operating expenses ($4,800) to arrive at your net operating income.So, the total net operating income:
The formula for net operating income: NOI = Gross Income - Operating ExpensesNow, substitute the values and get the NOI as follows:
NOI = Gross Income - Operating ExpensesNOI = (Sales+Sales) - [(variable expenses + variable expenses) + (fixed expenses + fixed expenses) + 137,200] NOI = (320,000+630,000) - [(158,100 + 343,800) + (72,300 + 135,100) + 137,200]NOI = 9,50,000 - (5,01,900 + 2,07,400 + 137,200)NOI = 9,50,000 - 8,46,500NOI = 1,03,500Therefore, the total net operating income (NOI) of both divisions is $1,03,500.

Answers
Answer
Option B is correct.
9.56556555... is an irrational number.
Step-by-step Explanation
Rational numbers are numbers that can be expressed as a clear fraction consisting of the numerator and the denominator both being integers.
The decimal form or decimal expansion of a rational number terminates after a particular/finite number of digits (e.g., 0.25, 0.762 etc.) or begins to repeat/recur the same sequence over and over again (e.g., 0.333..., 0.267267... etc)
Anything other than these two rules, the number is regarded as an irrational number.
The number given is 9.56556555...
The dots indicate thst the numbers after the decimal point conbtinue till eternity.
Observing the numbers after the decimal point for the given number, one can see that 565 repeats once and then the number after the second 565 is 55, indicating that the 565 doesn't recur till infinity.
Since the numbers after the decimal point doesnt contain a finite number of digits and the numbers don't recur till infinity, we can conclude that 9.56556555... isn't a rational number.

μ = 782.02 is the mean of the distribution of scores by standard deviation.
What is standard deviation in math?
A statistical measurement called standard deviation examines how far away from the mean a set of statistics is. Standard deviation, to put it simply, gauges the degree of dispersion between numbers in a data collection. The variance's square root is used to generate this metric.we have from standard normal table that
P(Z > 1.282) = 0.1
Therefore the given Z score of a score of 700 is given thus 1.282.
the z score is given:
x - μ / α = 1.282
700 - μ / 90 = 1.282
Therefore μ = (700 - 90)*1.282 = 782.02
So we have that μ = 782.02

• a =10
,• b = 4
Explanation:
An isometry is a rigid transformation that preserves length and angle measures, as well as perimeter and area.
This means that the two right triangles are congruent.
Thus, we have that:
[tex]\begin{gathered} 3a=30 \\ 10b=40\degree \end{gathered}[/tex]Next, we solve for a and b.
[tex]\begin{gathered} 3a=30 \\ \text{Divide both sides by 3} \\ \frac{3a}{3}=\frac{30}{3} \\ a=10 \end{gathered}[/tex]Likewise:
[tex]\begin{gathered} 10b=40\degree \\ \text{Divide both sides by 10} \\ \frac{10b}{10}=\frac{40\degree}{10} \\ b=4 \end{gathered}[/tex]The values of a and b are 10 and 4 respectively.

Given the table in I which represents function I.
x y
0 5
1 10
2 15
3 20
4 25
• Graph II shows Item II which represents the second function.
Let's determine the increasing and decreasing function.
For Item I, we can see that as the values of x increase, the values of y also increase. Since one variable increases as the other increases, the function in item I is increasing.
For the graph which shows item II, as the values of x increase, the values of y decrease, Since one variable decreases as the other variable decreases, the function in item I is decreasing.
Therefore, the function in item I is increasing, and the function in item II is decreasing.
ANSWER:
A. The function in item I is increasing, and the function in item II is decreasing.

We can convert a measure from radians to degrees by taking into account that π radians is equivalent to 180°.
Then, we can convert a measure in radians into degrees by multiplying by 180°/π.
We can convert 7π/11 into degrees as:
[tex]\frac{7\pi}{11}\cdot\frac{180\degree}{\pi}=\frac{7\cdot180\degree}{11}\approx114.55\degree[/tex]Answer: 114.55°

We have an algebraic problem where we have to solve for "w"
[tex]3x+2k=\frac{15y}{9w-18v}[/tex]Solving for "w"
[tex]\begin{gathered} 9w-18v=\frac{15y}{3x+2k} \\ w=\frac{\frac{15y}{3x+2k}}{9}+\frac{18v}{9} \\ w=\frac{15y}{27x+18k}+2v \end{gathered}[/tex]The previous result is the solution to the problem without simplifying, the error is that you have in the image, in the denominator the factor "23x" in reality this is "27x"
Now we can simplify this by taking out the third part of the whole fractional term
For him we divide everything by 3, being the third part of 15, 27, and 18 respectively 5, 9, and 6.

If agardener wants to calculate the costofgrass seed required to plant the lawn,what additional information wouldhe need to know?A the location of the walkwayBthe perimeter of the lawnс the weight of one bag of grass seedD the area that can be covered byone bag of seed
Answers
He needs option D. Because the perimeter is not the total area (it is only the distance in meters/centimeters that surround the lawn, we need to know how much area a bag of grass seeds covers, for us to know how many to buy. Also, we need the area of the walkway, since it is not covered by grass
The area of a triangle is:
[tex]Area\text{ = }\frac{b(h)}{2}[/tex]But, since there is a walkway that isn't covered in grass, we need to subtract the circle area from the triangle area
Area of circle:
[tex]Area\text{ = }\pi r^2[/tex]Then the total area of the lawn :
[tex]Area\text{ Lawn = }\frac{b(h)}{2}\text{ - \lparen}\pi r^2)[/tex]
