Steve and Michelle Neely are celebrating their 30th anniversary by having a reception at a local reception hall. They have budgeted $4,000 for their reception. If the reception hall charges a $80 cleanup fee plus $39 per person, find the greatest number of people that they may invite and still stay within their budget.
Answer:
100 people.
Step-by-step explanation:
$4,000 (total budget) - $80 (clean-up fee) = $3,920
$3,920 divided by $39 per person = 100.51
A total of 100 people could be invited for the Neely's to stay within their budget.
The greatest number is 100 people that they may invite and still stay within their budget.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
We have been given that they have budgeted $4,000 for their reception. If the reception hall charges an $80 cleanup fee plus $39 per person.
We have to determine the greatest number of people that they may invite and still stay within their budget.
Here total budget = $4,000
And clean-up fee = $80
Apply the subtraction operation,
⇒ 4,000 - 80
⇒ 3,920
We need 3,920 divided by $39 per person for finding the greatest number of people that they may invite.
⇒ 3,920/39
⇒ 100.51
Therefore, the greatest number is 100 people that they may invite and still stay within their budget.

A recipe that makes 18 cookies calls for 3/4cup of sugar how much sugar is needed to make 2 dozen cookies using this recipe
Answer:
Use 1 cup sugar to make 2 dozen (24) cookies.
Step-by-step explanation:
Recall that 1 dozen = 12 pieces
Write and solve an equation of ratios: # of cookies on one side and # of cups of sugar on the other side:
18 cookies (3/4) cup sugar
--------------------- = ------------------------
24 cookies x
Cross-multiplying results in:
18x = 18, so that x must be 1.
Use 1 cup sugar to make 2 dozen (24) cookies.

Find the y and x and the given slope of the given line: Line E.
Answer:
change in y: 0
change in x: 5
slope: 0
Step-by-step explanation:
Sub these two points from Line E into the gradient formula (you can search this up on the internet) and you would get 0/5
Points: (1,3) and (6,3)
Rise over run
3-3 over 6-1
0/5 and the answer is 0
Generally, when it asks you to find the slope of a horizontal line, its always 0

how to solve this sum with detailed explaination
Answer:
A = (- 1, 0 ) and B = (4, 0 )
Step-by-step explanation:
Given
y = x² - 3x - 4
To find the x- intercepts, let y = 0, that is
x² - 3x - 4 = 0
Consider the factors of the constant term (- 4) which sum to give the coefficient of the x- term (- 3)
The factors are - 4 and + 1 , since
- 4 × 1 = - 4 and - 4 + 1 = - 3, thus
(x - 4)(x + 1) = 0
Equate each factor to zero and solve for x
x - 4 = 0 ⇒ x = 4 ⇒ point B
x + 1 = 0 ⇒ x = - 1 ⇒ point A

1 pts Question 5 3.c. A map of a rectangular park has a length of 4 inches and a width of 6 inches. It uses a scale of 1 inch for every 30 miles. The map needs to be reproduced at a different scale so that it has an area of 6 square inches and can fit in a brochure. At what scale should the map be reproduced so that it fits on the brochure? 1 inch to___ miles
Answer:
The actual area 21600 miles²
Step-by-step explanation:
Lets explain how to solve the problem
- A drawing that shows a real object with accurate sizes reduced or
enlarged by a certain amount called the scale
- Drawing scale is a ratio between the drawing length and the
actual length
- To find the actual dimensions from the drawing dimensions use the
scale drawing
* Lets solve the problem
- A map of a rectangular park has a length of 4 inches and a width
of 6 inches
∴ The drawing dimensions are:
# length = 4 inches
# width = 6 inches
- The scale of the map is 1 inch foe every 30 miles
∴ The scale drawing is 1 : 30
- To find the actual area find the actual dimensions
∵ The scale drawing is 1 : 30
∵ The length = 4 inches and the width = 6 inches
- By using cross multiplication
∴ 1 : 30
4 : actual length
6 : actual width
∴ Actual length = (4 × 30)/1 = 120
∴ Actual length = 120 miles
∴ Actual width = (6 × 30)/1 = 180
∴ Actual Width = 180 miles
∴ The actual dimensions are 120 miles and 180 miles
∵ The area of any rectangle = length × width
∴ The actual area = 120 × 180 = 21600
∴ The actual area 21600 miles²

Answer:
The third one(-20+(n-1)*)
Step-by-step explanation:
It's correct because when you plug in one of the numbers in the list, it makes the equation equal. Example Below.
n=4
n=-20+(n-1)8
4=-20+(4-1)8
4=-20+3*8
4=-20+24

Daryl has a total of 120 national football league (NFL) trading cards from both the American football conference(AFC) and the national football conference (NFC). The number of AFC cards is 5 more than four times the number of NFC cards . Which system of equations can be used to find how many AFC cards, A and NFC cards,N, Daryl has?
Answer:
A = 4N + 5
A + N = 120
Step-by-step explanation:
Given that
A = Number of AFC cars
N = Number of NFC cards
And, Total cards is 120
Now
the equation would be
A + N = 120
Also
The number of AFC is 5 more than 4 times the number of NFC cards
So,
A = 4N + 5
Therefore
A = 4N + 5
A + N = 120
Hence, the system of equations that should be used is A = 4N + 5 and A + N = 120 respectively
Perimeter 94 cm and length 39. What’s the width
Answer:
8
Step-by-step explanation:
Take the length and multiply it by 2. then take your answer and multiply it by the perimeter. Then, take that answer and divide it by 2. Hope this helps :)
Hello.
To find the perimeter of a rectangle, use the formula P = 2(l + w).
Input 39 as l.
94 = 39 + 39 + w + w
Simplify
94 = 78 + 2w
Subtract the two known numbers
94 - 78 = 16
16 = 2w
So that means w = 8.
The width is 8.

Answer:
k = 3
Step-by-step explanation:
Assuming the values in the table are in direct proportion, then
y = kx ← is the equation relating x and y with k the constant of proportion, thus
k = [tex]\frac{y}{x}[/tex]
To find k substitute (28, 84 ) into the equation
k = [tex]\frac{84}{28}[/tex] = 3
