the width of a large, rectangular-shaped tree farm is 1.9 kilometers. The length of the farm is 4.4 kilometers. What is the best estimate of the area of the farm ?
Answer:- The best estimate of the area of the farm is 8 kilometers.
Explanation:-
Given:- Width of the rectangular shaped tree farm= 1.9 kilometers
⇒Estimated width of the farm=2 kilometers [2 is the nearest integer to 1.9]
Length of the rectangular shaped tree farm=4.4 kilometers
⇒Estimated length of the farm=4 kilometers [4 is the nearest integer to 4..4]
To make estimates, we usually round the numbers the nearest integer.
Now, Estimated Area of the Farm= estimated width × estimated length
= 2×4 kilometers = 8 kilometers.
∴the best estimate of the area of the farm =8 kilometers.
If your expenses are more than your income, then you have a positive net cash flow. Please select the best answer from the choices provided T F
Answer:
No, it is not a positive net cash flow. Because they are spending more than they even have which is creating debt.
Step-by-step explanation:
If your expenses are more than your income, then you have a positive net cash flow, which is false.
What is cash flow?The cash balance of liquid assets coming into and going out of a business is referred to as cash flow. Money spent and money received reflect inflows and outflows, respectively.
The cash flow is the difference between outflow and inflow.
Cash flow = out flow - inflow
If the value of the cash flow is negative that means the expense is more.
If the value of the cash flow is positive that means the income is more.
If your expenses are more than your income, then you have a positive net cash flow, which is false.

Karla is mowing her lawn. She knows 2/5 of the lawn before stopping for a snack. She resumes mowing after her snack and mows another 1/3 of her lawn before stopping. What total fraction of the lawn does Karla mow before lunch?
Karla mows a total of 11/15 of her lawn before lunch after adding the fractions 2/5 and 1/3 with a common denominator of 15.
The student's question has two parts where Karla mows her lawn in fractions, first 2/5 and then another 1/3. To find the total fraction of the lawn that she mows before lunch, these two fractions need to be added. However, since they do not have the same denominator, we first need to find a common denominator to combine these fractions properly.
The least common denominator (LCD) for 5 and 3 is 15. We convert the fractions to have this common denominator:
(2/5) becomes (6/15) after multiplying both the numerator and denominator by 3.(1/3) becomes (5/15) after multiplying both the numerator and denominator by 5.Now we add the fractions:
(6/15) + (5/15) = (11/15)
Thus, Karla mows a total of 11/15 of her lawn before lunch.

Why do the functions f(x) = sin−1(x) and g(x) = cos−1(x) have different ranges?
In this exercise we want to explain why two more similar functions have different ranges, like this:
the values of the range are different because the domain in which the inverse function exists are different .
In this exercise we know that we are dealing with two distinct functions, like this:
What is the function of sine?The sine function is considered an odd function, as there is a symmetry in the graph with respect to the bisector of the odd quadrants. When a function is considered odd, we have that f (x) = -f (x), that is, sin (-x) = -sin (x).
What is the function of cosine?Cosine is a trigonometric function, used in a right triangle to define the ratio of the side adjacent to and the hypotenuse of this triangle.
So we can see that the reason the two functions have different ranges is associated with them having different domains.

Jimmy is a partner in an internet-based coffee supplier. The company offers gourmet coffee beans for $14 per pound and regular coffee beans for $7 per pound. Jimmy is creating a medium-price product that will sell for $9 per pound. The first thing to go into mixing bin was 18 pounds of the gourmet beans. How many pounds of the less expensive regular beans should be added?
To create a blend that sells for $9 per pound, when Jimmy has already added 18 pounds of the gourmet beans, he needs to add approximately 36 pounds of the regular coffee beans.
Explanation:This is a problem of mixtures in mathematics. Jimmy is attempting to create a new blend of coffee for his business that will have a price point between the regular beans and the gourmet beans.
First, let's understand the goal: A new blend worth $9 per pound. He has already added 18 pounds of gourmet beans which costs $14 per pound. To bring the overall cost down to $9 per pound, we need to add cheaper beans, worth $7 per pound.
Let's denote the weight of the regular beans needed as 'x'. We set up the equation based on weights and costs:
(18*$14 + x*$7) / (18 + x) = $9
Solving this equation, we find x to be around 36 pounds. So, Jimmy should add approximately 36 pounds of the regular beans to his mixture to reach the target price of $9 per pound.

Luka’s measurements are more precise, but Anja’s measurements are more accurate. Luka’s measurements are more accurate, but Anja’s measurements are more precise.
Luka’s measurements are more precise, but Anja’s measurements are more accurate.
What is measurement?In the study of science and mathematics, measurement is a fundamental concept. The characteristics of an object or event that we can compare to other things or events are quantified by measurement. When discussing the division of a quantity, the term "measurement" is the one that is used the most frequently. Also, when it takes a certain number of things to complete a certain task. We frequently encounter various length, weight, and time measurement types in our daily lives.
Given actual height of their friend is 59 inches
Luka recording 59 in, 58 in, 58in
Anja recording 59.3 in, 59.6 in, 58.2 in,
Accuracy is how close a measured value is to the actual value.
Precision is how close the measured values are to each other.
Accuracy:
Luka: ( 59 + 58 + 58 ) / 3 = 58.33
Anja: ( 59.3 + 59.6 + 58.2 ) / 3 = 59.03 ( closer to 59 )
Precision:
Luka : 59 - 58 = 1 ( subtract the lowest from the highest result )
Anja: 59.6 - 58.2 = 1.4
Luka's measurements are more precise, but Anja's measurements are more accurate.

A new sidewalk will be 4 ft wide, 280 ft long, and filled to a depth of 9 inches (0.75 ft) with concrete. How many cubic yards of concrete are needed?
Answer:
Volume of the pit is [tex]31.11[/tex] cubic yards.
Step-by-step explanation:
First lets change all the values to yards.
1 yard = 3 foot
Width in yards = [tex]\frac{4}{3}[/tex] yards
Length in yards = [tex]\frac{280}{3}[/tex] yards
Depth in yards = [tex]\frac{0.75}{3}[/tex] yards

There are 50 dimes in a roll of dimes, 40 nickels in a roll of nickels, and 40 quarters in a roll of quarters. Rob has 12 rolls of coins with a total value of $70.00. He has 3 more rolls of nickels than dimes. How many rolls of each coin does he have?
a collection of dimes and nickels is worth $4.70 there are 60 coins in all how many of each are there?
Answer:
26 nickels34 dimesStep-by-step explanation:
If all were nickels, the value would be 60×$0.05 = $3.00. Their $4.70 value is $1.70 more than that. For each nickel replaced by a dime, the value goes up by $0.05, so there must be 1.70/0.05 = 34 replacements. That is, ...
... there are 34 dimes and 60-34 = 26 nickels.
_____
Using an equation
In mixture problems, it often works well to let the variable represent the quantity of the largest contributor. Here, we can let "d" represent the number of dimes, the coin with the greatest value. Then 60-d will be the number of nickels, and the total value of the coins (in dollars) is ...
... (60 -d)×0.05 + d×0.10 = 4.70
... 0.05d + 0.05×60 = 4.70 . . .simplify
... 0.05d = 4.70 -3.00 . . . . . . . subtract 3.00
... d = 1.70/0.05 = 34 . . . . . . . . divide by the coefficient of d
There are 34 dimes and 26 nickels.
The sequence of math steps should look a lot like the sequence of steps described in words, above.
_____
As a mixture problem
The average coin value is 4.70/60 = 0.07833... = 7 5/6¢. Then the proportion that are dimes is given by ...
... (7 5/6 - 5)/(10 - 5) = (2 5/6)/5 = 17/30 . . . . . 10 and 5 are the cents values of the coins in the mix
Multiplying by the 60 coins, we find (17/30)×60 = 34 are dimes. The remaining 26 are nickels.
- - -
The formula used above is ...
... proportion of highest contributor = ...

A woman has 7 keys. only one of them will open her door. when seh arrives at the door there is no sufficient light for her to find the correct key. if she tries one key at a time and discards the keys that don't work, what is the probability that she will open the door with the first key she picks? what is the probability that it will take exactly three attempts to open the door? suppose that the first three attempts to open the door have been unsuccessful. what is the probability that she will pick the right key the fourth time?
The chance of the woman opening the door with the first key she picks is 1/7, or approximately 14.29%. The probability that it takes exactly three tries to find the correct key is also 1/7 or 14.29%. If the first three tries are unsuccessful, the probability that the fourth key is the correct key is 1/4, or 25%.
The probability that the woman will open the door with the first key she picks is 1 out of 7 keys, or about 14.29%. This is because each key has an equal chance of being the correct one, and there is only one correct key among the seven.
For the probability that it will take exactly three attempts to open the door, we need to consider the sequence of events: She picks a wrong key first (6 out of 7 chances), and then picks another wrong key from the remaining six (5 out of 6 chances), and then finally picks the correct key from the remaining five (1 out of 5 chances). We multiply these probabilities: (6/7) * (5/6) * (1/5) = 1/7 or about 14.29%.
If the first three attempts have been unsuccessful, we are now left with four keys, one of which is the correct one. Therefore, the probability that she will pick the right key on the fourth attempt is 1 out of 4, or 25%.

A plumbing contractor receives proceeds of $4,713.54 on a 12.5% simple discount note with a face value of $5,000. Find the time of the note in days. (Assume a 360-day year.) Do not round intermediate calculations!
The time of the note in days is calculated using the simple discount formula, and by substituting the values of proceeds, face value, and discount rate, the result is 164.99856 days.
The question involves finding the time in days for which a simple discount note is held, given the proceeds, face value, and discount rate. The note's face value is $5,000 and the proceeds received are $4,713.54. The simple discount rate is 12.5%. Assuming a 360-day year, we need to calculate the time period for the note.
Firstly, we need to determine the amount of the discount, which is the difference between the face value and the proceeds: $5,000 - $4,713.54 = $286.46. The discount, given the simple discount formula, is equal to the face value multiplied by the discount rate and the time (in years). The simple discount formula can be expressed as: Discount = Face Value × Discount Rate × Time. Rearranging this formula to solve for time, we get: Time = Discount ÷ (Face Value × Discount Rate).
Substituting the known values we have: Time = $286.46 ÷ ($5,000 × 0.125) = $286.46 ÷ $625 = 0.458336 years. To convert years to days, we multiply the time in years by the number of days in a year (assuming a 360-day year): 0.458336 years × 360 days/year = 164.99856 days. Since we're instructed not to round intermediate calculations, the time of the note is 164.99856 days.
