Answer:

yes youre right it is point D

Step-by-step explanation:

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

The scale model of the sports arena has a height of 12 inches.

Unit rate is the amount of something at a rate of one amount to another amount.

If 2 inches = 30 feet, then a sports stadium's height is 180 feet.

A man can walk 6 kilometers in 2 hours.

A man can cover 3 miles by walking in an hour.

A machine can cut 10 potatoes in five minutes.

A machine can cut two potatoes in a minute.

30 feet equals 2 inches.

Add 30 to both sides.

1 foot equals 2/30 inches.

1 foot equals 2/30 inches today.

Add 180 to both sides.

180 feet equals 180 x 2/30 inches.

6 × 2 inches times 180 feet.

12 inches equal 180 feet

Since the height of the sports stadium is 180 feet, 2 inches would equal 30 feet.

The scale model of the sports arena has a height of 12 inches.

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

The linear equation is:

y = 2x + 8

For 8 customers, the time will be:

y = 2*8 + 8

y = 24

It will take 24 minutes to serve 8 people.

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.

Step-by-step explanation:

We can create a system of inequalities by using the Triangle Inequality Theorem. This theorem states that the sum of two sides on a triangle is greater than the other sides.
1.) Figure out the first inequality. This would be 300+200>x, or x<500.

2.) Figure out the second inequality. This would be x + 200 > 300, or x>100.
3.) Figure out the third inequality. This would be x + 300 > 200, or x > -100.

4.) Combine these inequalities. By combining these inequalities, we would get 100<x<500.

Answer:3.71 miles

Step-by-step explanation:

(a) The Explicit Rule for f(n) is 0.1 × 3n The Recursive Rule for f(n) is f(n-1) × 3.  (b) The Explicit Rule for f(n) is 100 × 0.1ⁿ The Recursive Rule for f(n) is f(n-1) × 0.1

The explicit rule states that the value of the sequence at each term is 0.1 multiplied by 3 raised to the power of n. The recursive rule states that the value of the sequence at each term is equal to the value of the preceding term multiplied by 3. This can be seen in the table of values where each value is 3 times the preceding value.

Given,        

n = 0,1,2,3,4…        

f(n) = 0.1,0.3, 0.9, 2.7, 8.1

(b) The Explicit Rule for f(n) is 100 × 0.1ⁿ, The Recursive Rule for f(n) is f(n-1) x 0.1

Given,      

n= 0,1,2,3,4..      

f(n) = 100, 10, 1,0.1, 0.01

The explicit formula is the formula to calculate the value of the sequence directly without using any previous terms. The recursive formula uses the previous term to calculate the value of the current term.

In this example, the explicit formula is 100 × 0.1ⁿ and the recursive formula is f(n) = f(n-1) × 0.1. This means that each term in the sequence is equal to the previous term multiplied by 0.1.

For example, the third term in the sequence is 1, so the fourth term is 1 × 0.1 = 0.1.

(c) The Explicit rule for f(n) is 1000 × 0.1⁽ⁿ ⁻ ¹⁾, The Recursive rule for f(n) is f(n-1) x 0.1    

To solve,

f(5) = 1000 × 0.1⁽⁵ ⁻ ¹⁾(5-1)

     = 1000 × 0.1⁴

     = 1000 × 0.0001

     = 0.1

Given,        

n= 1,2,3,4,5…        

f(n) = 1000, 100, 10, 1, 0.1

The explicit and recursive rules for this geometric sequence are both written as f(n) = 1000 × 0.1⁽ⁿ ⁻ ¹⁾.  This means that the value of the sequence at any given point n will be equal to 1000 multiplied by 0.1 raised to the power of n-1. This means that the value of the sequence decreases by a factor of 0.1 for every increase in n.

In this case,

f(5) = 1000 x [tex]0.1^4[/tex]

     = 0.1.

(d) The Explicit Rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence.

The Recursive Rule for this geometric sequence is f(n) = f(n-1) ÷ 10³, where f(n) is the value for the nth term of the sequence and f(n-1) is the value for the (n-1)th term of the sequence.

Given,    

n= 1,2,3,4,5..    

f(n) = 10⁵⁰,10⁴⁷, 10⁴⁴, 10⁴¹, 10³⁸….

The value for the 5th term of the sequence is f(5) = 10⁽⁵⁰ ⁻ ³⁽⁵⁾⁾ = 10³⁸. The explicit rule for this geometric sequence is f(n) = 10⁽⁵⁰ ⁻ ³ⁿ⁾, where n is the term number of the sequence. This means that the value of each term is determined by taking 10 to the power of 50 minus 3 multiplied by the term number.

The recursive rule for this geometric sequence is [tex]\frac{f(n-1)}{10^3}[/tex] which means that the value of each term can be calculated by dividing the previous term by 10 cubes. We can use

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.

Congruent triangles under the SSS (Side Side Side postulate) condition.

Congruent triangles criterion according to the SAS (Side Angle Side postulate).

Congruent triangles are a requirement of the ASA (Angle Side Angle postulate).

The congruent triangles criterion of the AAS (Angle Angle Side postulate).

Answer:

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.

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]
