Step-by-step explanation:

The two errors that Sterling made in the proof include:

In this case, it should be noted that the step 6. statement must be that LEO is equal to NEO. This is due to the substitution property of equality.

The substitution property of equality states that one value can be substituted for another in an expression or equation and the result will be the same. If the values of x and y are equal, then x and y can be substituted for one another.

Also, the step 7 should be that OLE is identical to ONE. The reason is due to the angle-side-angle postulate. According to the AAS Postulate, if two angles and the non-included side of one triangle are congruent to two angles and the non-included side of another, the triangles are congruent.

What is the Equation of line?

The equation of the line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

we have given that;

After 13 minutes, the airplane has 32,882 gallons of fuel. After 31 minutes, the airplane has 34,902.5 gallons of fuel.

Now,

Since, After 13 minutes, the airplane has 32,882 gallons of fuel. After 31 minutes, the airplane has 34,902.5 gallons of fuel.

Hence, The equation of line passes through the points (13, 32882) and (31, 34902.5)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (32882 - 34902.5) / ((31 - 13)

m = 2020.5 / 18

m = 112.25

Thus, The equation of the line with slope 112.25 is,

⇒ y - 32885 = 112.25 (x - 13)

⇒ y - 32885 = 112.25x - 1459.25

⇒ y = 112.25x - 1459.25 + 32885

⇒ y = 112.25x + 31.425.75

Therefore, The function in f(t) form that describes the amount of fuel in the plane at time t will be:

Step-by-step explanation:

You want to know the tax rate if the added tax brings the cost of $45 purchase to a total of $54.

The multiplier applied to a purchase cost to add the tax is ...

   (1 +r)

where r is the tax rate.

Here, that means ...

  45(1 +r) = 54

  1 +r = 54/45 = 1.20

  r = 1.20 -1 = 0.20 = 20%

Triangles ΔAEC, ΔECD are congruent.

Three angles and three sides, or the six measuring components, specify the requirements for the congruence of triangles. But if three of these are correctly satisfied, the other three are also satisfied automatically. Axioms for congruency are four such instances.

At year-end, Factory Overhead is debit of $34000.

What is profit and loss?

A profit and loss (P&L) statement could be a monetary report that has a outline of a company’s revenue, expenses and profit. It provides investors and alternative interested parties an insight into however an organization is working and whether or not it's the flexibility to get a profit.

Main Body:

Estimated total overhead costs = $456,000

Estimated direct labor costs = $2,280,000

Actual overhead costs= $422,000

Actual direct labor costs= $1,940,000

To calculate the factory overhead, we need to first calculate Estimated overhead rate.

Estimated overhead rate = Estimated total overhead costs / Estimated direct labor costs

= $456,000 / $2,280,000

= 0.2

= 20%

Therefore;

Actual Factory overhead = Actual direct labor cost × application rate

= $1,940,000 × 20%

= $388,000

We can get the balance in the overhead account as shown below;

Balance = Actual overhead cost - Actual cost that should be applied

= $422,000 - $388,000

= $34,000 (Debit).

Hence there is debit of $34000.

What is the absolute maximum of an equation?

The highest conceivable values for f are represented by the absolute maximum (sometimes called the global maximum) of a function f(x) (x). Let's imagine the function's critical value, x=c, is present within its domain. If the inequality f(c) [tex]\geq[/tex] f(x), x is a domain, then the function f(x) is said to satisfy an absolute maximum when x=c.

To find the critical points, we find the value of f'(x) and equate to 0.

[tex]\frac{d}{dx} (\sqrt[11]{x^{2}+64} )=0[/tex]

we get x=0.

We see that f'(x) exists for all x between [-8,9].

We also find the endpoints, that is -8 and 9.

Then we calculate f(x) at critical points and endpoints.

We calculate f(x) at 0, -8, and 9.

We get,

for x=0, f(x)= [tex]2^{\frac{6}{11} }[/tex]

for x=-8, f(x)= [tex]2^{\frac{7}{11} }[/tex]

for x=9, f(x)= [tex]\sqrt[11]{145}[/tex]

We see that the value is maximum at x=9, and f(x) becomes [tex]\sqrt[11]{145}[/tex].

Hence we get the absolute maximum is [tex](x,f(x))\\[/tex] = [tex](9,\sqrt[11]{145} )[/tex] = [tex](9,1.6)[/tex]

By finding an evaluating a linear equation we will see that it takes 24 minutes to serve a group of 8 people.

Let's assume that the relation between the number of people and the time it takes to serve them is linear.

A general linear equation is written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

If the line passes through two points (x1, y1) and (x2, y2), then the slope is:

a = (y2 - y1)/(x2 - x1)

Here we have two points:

1 person, 10 minutes, written as (1, 10)

5 people, 18 minutes, written as (5, 18)

Then the slope is:

a = (18 - 10)/(5 - 1)

a = 8/4 = 2

Then the linear equation is:

y = 2x + b

To find the value of b, we can replace the values of one of the points, I will use (1, 10) so we will get:

10 = 2*1 +b

10 = 2 + b

10 - 2 = b

8 = b

Answer:

Step-by-step explanation:

The mean of numbers is the sum of the numbers divided by the number of numbers. By this definition, we first have to add up all of these numbers. If we do, we get 48. Now, we figure out the number of numbers, which is 6. Finally, we divide 48 by 6 to get 8.

Step-by-step explanation:

we know that the two angles with x are equal since they are made with the same lines

so

8x+36=5x+51

solve for x

a. subtract 36 from both sides

8x=5x+15

b. subtract 5x on both sides

3x=15

c. divide by 3

x=3

now to find z

we know a line equals 180

so

(8x+36)+z=180

plug in 3

8(3)+36+z=180

24+36+z=180

60+z=180

z=120

Arc QR = 48°

Arc RS = 96°

Arc QPS = 216°

Arc PSR = 186°

Arc SRQ = 144°

The inscribed angle theorem state that the measure of an intercepted arc is equal to twice the measure of the inscribed angle.

Find arc PSR:

Arc PSR = 2(93) [based on the inscribed angle theorem]

Arc PSR = 186°

Find arc QR:

Arc QR = 360 - arc PQ - arc PSR

Arc QR = 360 - 126 - 186

Arc QR = 48°

Arc RS = arc PSR - arc PS

Arc RS = 186 - 90

Arc QPS = 126 + 90

Arc QPS = 216°

Arc PSR = arc PS + arc RS

The “edge” effect of a tetrahedral container with edge length of 1,000 mm would be 2*r*√3 (r = radius of ball, see diagram below). For a ping pong ball with a diameter of 40 mm, the edge effect would be 2*20*√3 = 69.28 mm. Subtract that from 1,000 mm and you get 930.72 mm of “available space” along the bottom row. Divide 930.72 mm by 40 mm per ball and you get 23.27. So you wouldn’t be able to fit 24 balls along the base, you’d only be able to fit 23 balls. With 23 balls, the total number that a tetrahedron could contain (T) would be T = n(n+1)(n+2)/6 = 2,300 balls, not 2,600.
