What is unitary method ?Unitary method is a mathematical way of first deriving the value of a single unit then multiplying the given unit to obtain the required result.
According to the given question we have to compare the results where in first case we put actual values and on the second case we round the values.
In the first case
You're going on a 1211 mile trip, and your car gets about 29 miles per gallon.
So, the total fuel consumption will be (1211/29) gallons which is
= 41.76 gallons.
Given 1 gallon of gas costs 3.10 dollars.
∴ 41.76 gallons of gas will cost ( 41.76×3.10) dollars which is
= 129.456 dollars.
= 129.46 dollars.
In the second case
It is a 1200 mile trip and the fuel economy of the car is 30 miles per gallon.
So, the total fuel consumption will be
= 1200/30
= 40 gallons.
Given 1 gallon of gas costs 3 dollars.
∴ 40 gallons of gas costs (40×3) dollars which is
= 120 dollars.

LeAnn wants to gift wrap a present she got for her little brother. How many square inches of gift wrap will be needed to cover a box that is 4 in x 6 in x 2 in ? In your final answer, include all of your calculations.
All calculations for answer in picture form
Answer:
There are 88 square inches needed to cover a box that is 4 in • 6 in • 2 in
Step-by-step explanation:
In order to cover the box you need to find the surface area of it. The formula for finding the surface area of a rectangular prism is 2 • ((w•l) + (h•l) + (h•w)). The dimensions of the box is 4 inches in length, 6 inches in width, and 2 inches in height.
Apply the dimensions into the formula of the rectangular prism when the numbers are plugged in it results in 2 ( (6•4) + (2•4) + (2•6) )Multiply the dimensions the area of length• width is 24 (six times four is twenty-four), the area of height•width is 8 (two times four is eight), and the area of height•width is 12 (two times six is twelve). At the end of this step it becomes 2 • ((24) + (8) + (12))Add all the numbers inside the parentheses then it becomes 2 • (44) Multiply the number in parentheses by 2 the final answer is 88 in²An isolated agricultural country has two distinct regions: a lowland plain and an upland of rugged hills. On one unit of land on the PLAIN, a farmer can raise 10 bushels of grain or graze 10 sheep. On one unit of land in the HILLS, a farmer can raise 2 bushels of grain or graze 4 sheep.
Determine which region has the absolute advantage for sheep production. Explain your answer.
Hills region has the advantage for sheep production because when a farmer raised 2 bushels of grain, then gaze 4 sheep.
The most popular animal fiber is sheep's wool, which is often gathered by shearing. In Commonwealth nations, ovine meat is referred to as lamb when it comes from younger animals and mutton when it comes from older ones; in the United States, meat from both older and younger animals is often referred to as a lamb.
Today, sheep are still farmed for their meat and wool, as well as on occasion for their pelts, as dairy animals, or as scientific model organisms. Most of the world's populated areas engage in sheep farming, which has been a foundational activity for several civilizations.

answer, include all of your calculations.
y= x/x^2-1
Step-by-step explanation:
the y-intercept is the y value when x = 0.
the x-intercept is the x value when y = 0.
for x = 0
y = 0 / (0² - 1) = 0/-1 = 0
this automatically answers also our question about the x value when y = 0. we found this out already with the y-intercept.

Give A || B, find each of the indicated angle measures. Given: m<3=63 Find:m<6,m<7
m<6 = 117° based on the same-side-interior angles theorem
m<7 = 63° based on the corresponding angles theorem
What is the Same-Side Interior Angles Theorem?Angles 3 and 6 are same-side interior angles, therefore, based on the same-side-interior angles theorem, their sum equals 180 degrees because they are supplementary to each other.
Thus:
m<3 + m<6 = 180
Substitute
63 + m<6 = 180
m<6 = 180 - 63
m<6 = 117°
m<7 = m<3 [corresponding angles theorem]

Can anyone explain this?
Answer:
0.250
Step-by-step explanation:
Given from the question, we know that the summation (adding all values together) of all P(x) values is equal to 1.
And, we do know that P(2) = P(4).
This means , we will subtract all the known P(x) values from 1 to get the value of P(2) + P(4).
P(2) + P(4) = 1 - 0.0425 - 0.3750 - 0.0625 - 0.0200 = 0.500
Since P(2) = P(4), we divide 0.500 by 2 to get the value of P(2) and P(4).
P(2) = P(4) = 0.500 ÷ 2 = 0.250

The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions) comprising trigonometry are the cosecant, cosine , cotangent , secant , sine , and tangent .
The trigonometric function can be described as being even or odd.
Odd trigonometric functions: A trigonometric function is said to be an odd function if f(-x) = -f(x) and symmetric with respect to the origin.
Even trigonometric functions: A trigonometric function is said to be an even function, if f(-x) = f(x) and symmetric to the y-axis.
Hence, the top of the pole from the ground is 13.314798.

PLS HELP!! Write an equation in point-slope form for a line that passes through the given set of points. (-1,-2)(-3,1)
Write the equation of the line that passes through the points (1,1) and (11,−2).
The equation of the line in slope-intercept form is: y = -3/10x + 13/10.
How to Write the Equation of the Line?Given the points, (1,1) and (11,−2). Follow the steps explained below.
Step 1: Find the slope of the line:
Slope (m) = change in y / change in x = (-2 - 1)/(11 - 1)
Slope (m) = -3/10
Step 2: Substitute m = -3/10 and (a, b) = (1, 1) into y = mx + b to find the value of b
1 = -3/10(1) + b
1 = -3/10 + b
1 + 3/10 = b
b = 13/10
Step 3: Substitute m = -3/10 and b = 13/10 into y = mx + b
y = -3/10x + 13/10

Step-by-step explanation:

Answer:
f^-1(33) = 7
Step-by-step explanation:
As the question is asking for the inverse function we do the following steps:
Change f(x) into y :
y = 9 -6x
Swap x and y :
x = 9-6y
Solve for y :
Subtract 9 from both sides :
x-9 = -6y
Divide both sides by -6 :
(x-9)÷ -6 = y
Change y back into f(x) :
f(x) = (x-9)÷ -6
Now substitute -33 into x :
((-33)-9) ÷ - 6 =

To test the ability of mechanics to identify simple engine problems, a car with a single such problem was taken in turn to 72 different car repair facilities. Only 42 of the 72 mechanics who worked on the car correctly identified the problem. Does this strongly indicate that the true proportion of mechanics who could identify this problem is less than 0.75?
a) Perform the appropriate test of hypothesis using = 0.01. Clearly show the eight (8) steps
Using the z-distribution, it is found that since the p-value is less than 0.01, there is strong indication that the true proportion of mechanics who could identify this problem is less than 0.75.
What are the hypotheses tested?At the null hypotheses, it is tested if there is not enough evidence that the proportion is less than 0.75, that is:
[tex]H_0: p \geq 0.75[/tex]
At the alternative hypotheses, it is tested if there is enough evidence that the proportion is less than 0.75, that is:
[tex]H_1: p < 0.75[/tex]
What is the test statistic?The test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
In which:
[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.For this problem, the parameters are given as follows:
[tex]n = 72, \overline{p} = \frac{42}{72} = 0.5833, p = 0.75[/tex]
Hence the test statistic is given by:
[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]
[tex]z = \frac{0.5833 - 0.75}{\sqrt{\frac{0.75(0.25)}{72}}}[/tex]
z = -3.27.
What is the p-value of the test?Considering a left-tailed test, as we are testing if the proportion is less than a value, with z = -3.27, the p-value is < 0.01.
Since the p-value is less than 0.01, there is strong indication that the true proportion of mechanics who could identify this problem is less than 0.75.

interest rate. What should the length of the loan be? Round your answer to the nearest year.

Then,
[tex]n = \frac{\text{Ln}(A) - \text{Ln}(A-L)}{\text{Ln}(1+i)}\\\\n \approx \frac{\text{Ln}(134116.384787) - \text{Ln}(134116.384787-20000)}{\text{Ln}(1+0.00354)}\\\\n \approx \frac{11.80646 - 11.64497}{0.00353}\\\\n \approx \frac{0.16149}{0.00353}\\\\n \approx 45.74788\\\\n \approx 46[/tex]
It will take about 46 months to pay off the loan.
