Answer:
Break-even point is at quantity 220.
Step-by-step explanation:
Given the rent amount that is fixed cost for the store = $550
The average cost of the goods = $3
The average price of the goods = $5.50
Let the total number of break-even items = Q
Thus, total revenue = 5.50 x Q = 5.50Q
At break-even, TR = TC
5.50Q = FC + VC
5.50Q = 550 + 3Q
5.50Q - 3Q = 550
2.50Q = 550
Q = 550 / 2.50
Q = 220
Thus break-even point is at quantity 220.

Lydia bought a car for 20,000. It is expected to depreciate at a rate of 10% per year. What will be the value of the car in 2 years? use y=a(1-r)^t and round to the nearest dollar
Answer:
$16,200
Step-by-step explanation:
y = 20,000(1 - 0.1)^2
y = 20,000(0.9)^2
y = 20,000(0.81)
y = 16,200

Step-by-step explanation:
the smaller triangle is the larger triangle divided by 4 so 16÷4 is 4.
Find the measure of a single exterior angle of the regular polygon shown below. If necessary, round to the nearest tenth.
Answer:
32.7°
Step-by-step explanation:
Applying,
The measure of single exterior angle(S') = sum of exterior angle(S)/number of sides of the polygon(n)
S' = S/n................... Equation 1
If the sum of the exterior angle of a convex polygon(S) = 360°
From the diagram in the question,
Given: n = 11 sides
Substitute into equation 1
S' = 360/11
S' = 32.7°
The sum of three consecutive even numbers is 24 , find the numbers.
Answer:
three consecutive even integers whose sum is 24 are 6, 8 and 10.
Divide the total by amount of numbers. This will be the middle value:
24/3 = 8
The numbers are consecutive even numbers so use the even number below and above 8, which are 6 and 10.
6 + 8 + 10 = 24
The 3 consecutive even numbers are 6, 8 and 10

What is the volume of the following rectangular prism? 1 3/4 1/2 i need a direct answer
Answer:
V = 0.375 units³
Step-by-step explanation:
The volume of a rectangular prism is V = lwh.
Where l is the length, w is the width, and h is the height.
Given 1 unit(s) for the length, ¾ unit(s) for the width, and ½ unit(s) for the height.
V = lwh
V = (1)(¾)(½) units
V = (⅜) units
V = 0.375 units

Hi there!
We are given the set of ordered pairs below:
[tex] \large \boxed{(3, - 1),(2, - 2),(0,2),(2,1)}[/tex]
1. What is the domain?
Domain is a set of all x-values in one set of ordered pairs. So what are the x-values that I am talking about? In ordered pairs, we define x and y which both have relation to each others which we can write as (x,y). That's right, the domain is set of all x-values from ordered pairs.Therefore, we gather only x-values from (x,y). Hence, the domain is {3,2,0,2}. Whoops! Something is not right. As we learn in Set Theory that we don't write the same or repetitive in a set. Hence, the actual domain is {0,2,3}
2. What is the range?
Because domain is set of all x-values. Then what do you think the range is? That's right! The range is set of all y-values. If you got this right before looking up the underlined words then a handclap for you! So how do we find range? Simple, we just do like finding the domain in the Q1, except we gather the y-values in (x,y) instead and make sure that we don't write same number!Therefore, gather y-values from the ordered pairs. Hence, the range is {-2,-1,1,2}
3. Is the relation a function?
All functions are relations but not all relations are functions. Function is a set of ordered pairs where domain is not repetitive or in a set, there cannot be more than one same value. Consider the following relation: (1,1),(1,2) - Oh, looks like in a set of ordered pairs, there are two same domains which make it only a relation, and not a function. On the other hand, (1,1),(2,2) - Looking good! No same or repetitive domain, making it indeed a function.Consider the domain from Q1 and see if there are two same values of x in a set. Looks like the relation is not a function since there are same x-values which are 2 in a set, making it only a relation. Hence, the relation is not a function.
These are all 3 answers along with an explanation. Let me know if you have any doubts regarding Relations and Functions.
From the Q1's answer, there are two bold texts, please choose the second bold text to answer (the one with underline) and not the first one (the one with same 2's).
Good luck on your assignment, have a nice day!
What is the output of y=23x−4 when the input is 18?
Enter your answer as a number, like this: 42
Answer:
410
Step-by-step explanation:
Inputs are x's
Substitute the 18 where you see the x
y = 23(18) - 4
y= 414 - 4
y = 410
An electrician leans an extension ladder against the outside wall of a house so that it reaches an electric box 28 feet up. The ladder makes an angle of 64 ∘with the ground. Find the length of the ladder. Round your answer to the nearest tenth of a foot if necessary.
Answer:
31.2 ft
Step-by-step explanation:
sin = opp/hyp
sin64 = 28/hyp
hyp = 28/sin64
use calculator
hyp = 31.15285433330529
Rounded
31.2 ft
The length of the ladder needed to reach an electric box 28 feet up is 31.2 feet.
The ladder, the distance from the wall to the base of the ladder and the distance from the ground to the electric box forms a right angled triangle.
Trigonometric ratios shows the relationship between the sides and angles of a right angled triangle.
Let x represent the length of the ladder, hence:
sin(64) = 28 feet/x
x = 28 feet / sin(64)
x = 31.2 feet
Hence the length of the ladder needed to reach an electric box 28 feet up is 31.2 feet.

You decide to invest $800 for 6 years and you have a choice between two accounts. The first
pays 7% per year compounded monthly. The second plan pays 6.85% per year, compounded
continuously. Which is the better investment? Explain. *
Answer:
the first plan is better
this is because the effective annual interest of the first plan is 7.23 which is higher than that of the second plan which is 7.09. this means that the interest rate of the first option would be higher
2. the future value of option 1 is higher than that of option 2
Step-by-step explanation:
The effective annual rate can be used to determine which option is better
the option with the higher effective annual rate is the better option
Effective annual rate = (1 + APR / m ) ^m - 1
M = number of compounding
(1 + 0.07/12)^12 - 1 = 7.23%
option 2
EAR = e^r - 1
2.7182818^0.0685 - 1 = 7.09%
2nd method of determining the better investment is to determine the future value of each option
Option 1 : 800( 1 + 0.07/12)^(12 x6) = 1216.08
option 2 = 800e^(0.0685 x 6) = 1206.60
option 1 has the higher future value
Answer:6757.62
Step-by-step explanation:

Russell, Sarah, and Terry share money in the ratio 2:5:8. In total they have £120. Work out how much each gets.
Answer:
£16, £40, £64
Step-by-step explanation:
sum the parts of the ratio, 2 + 5 + 8 = 15 parts
Divide the amount by 15 to find the value of one part of the ratio.
£120 ÷ 15 = £8 ← value of i part of ratio , then
2 parts = 2 × £8 = £16 ← amount Russell gets
5 parts = 5 × £8 = £40 ← amount Sarah gets
8 parts = 8 × £8 = £64 ← amount Terry gets
Answer:
$16, $40, $64
Step-by-step explanation:
The ratio is 2:5:8. Altogether, this adds up to 15. So they divided $120 into 15 portions. 120/15=8.
Russel got 2 portions of 8 dollars, Russel got $16
Sarah got 5 portions of 8 dollars, Sara got $40
Terry got 8 portions of 8 dollars, Terry got $64

The equation y1=x^2−4x represents Function 1. The graph of Function 1 is shown
Function 2 is represented by the equation y2=x−6. Which values are solutions to y1=y2? Select each correct solution.
x=−6
x=0
x=1
x=2
x=3
x=6
Answer:
x = -1, 6
Step-by-step explanation:
Equation of function 1 is,
y₁ = x² - 4x
Equation of function 2 is,
y₂ = x - 6
If y₁ = y₂
x² - 4x = x - 6
x² - 4x - x + 6 = 0
x² - 5x + 6 = 0
x² - 6x + x + 6 = 0
x(x - 6) + 1(x + 6) = 0
(x + 1)( x - 6) = 0
x = -1, 6
Answer:
x = 2 and x = 3
Step-by-step explanation:
y1 = 2^2 - 4(2)
2 x 2 - 8= -4
y2 = 2 - 6 = -4
y1 = 3^2 - 4(3)
9 - 12 = -3
y2 = 3 - 6 = -3
