What is Addition?Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.
The process of doing addition is also called as finding the sum.
The given is,
∑n=18(3n−1)
The top number is 8 and the bottom number is 1.
Finding the sum,
Sum = [18(3 - 1)] + [18(6 - 1)] + [18(9 - 1)] + [18(12 - 1)] + [18(15 - 1)] + [18(18 - 1)] + [18(21 - 1)] + [18(24 - 1)]
= 36 + 90 + 144 + 198 + 252 + 306 + 360 + 414
= 1800

Answers
You own a hamburger franchise and are planning to shut down operations for the day, but you are left with 15 buns, 21 defrosted beef patties, and 17 opened cheese slices. Rather than throw them out, you decide to use them to make burgers that you will sell at a discount. Plain burgers each require 1 beef patty and 1 bun, double cheeseburgers each require 2 beef patties, 1 bun, and 2 slices of cheese, while regular cheeseburgers each require 1 beef patty, 1 bun, and 1 slice of cheese. How many of each should you make? plain burgers:______ double cheeseburgers:_______ regular cheeseburgers:_______
Answers
With the remaining items, you would make 5 cheeseburgers and 4 hamburgers if you want to use up the remaining items.
The goal here is to have the same number of buns and burger remaining after the double cheeseburgers.
Final answer:
To use the ingredients efficiently, the franchise should make 4 plain burgers, 8 double cheeseburgers, and 1 regular cheeseburger, effectively utilizing all available buns, beef patties, and cheese slices.
Explanation:
To solve the problem of how many plain burgers, double cheeseburgers, and regular cheeseburgers you should make, you need to consider the ingredients as your limiting factors. Starting with the resources available: 15 buns, 21 beef patties, and 17 cheese slices. The recipes are as follows: plain burgers require 1 beef patty and 1 bun; double cheeseburgers require 2 beef patties, 2 cheese slices, and 1 bun; regular cheeseburgers require 1 beef patty, 1 cheese slice, and 1 bun.
First, notice that the number of buns is the overall limiting factor for the maximum number of burgers you can make, which is 15.Second, consider maximizing the use of cheese slices by making as many double cheeseburgers as possible, which would be 8 (consuming 16 beef patties and 16 cheese slices, leaving 5 buns, 5 beef patties, and 1 cheese slice).With the leftovers, you can make 1 regular cheeseburger (using 1 more beef patty, 1 cheese slice, and 1 bun) and then 4 plain burgers with the remaining 4 beef patties and buns.Therefore, you should make 4 plain burgers, 8 double cheeseburgers, and 1 regular cheeseburger to utilize the ingredients efficiently without waste.
For each of the following determine the 1-unit growth factor.
The 1-unit percent change is -56.25%.
Please help explain so I can figure one out and do the rest on my own. Thanks!
Answers
A 1-unit growth factor with a -56.25% change means the quantity decreases by 43.75% when it decreases by 1 unit, resulting in a factor of 0.4375.
The 1-unit growth factor represents the factor by which a quantity changes when it increases by 1 unit.
A 1-unit percent change of -56.25%. A negative percent change indicates a decrease rather than an increase.
To find the 1-unit growth factor when the percent change is -56.25%,
use the formula:
Growth Factor = Final value / Initial value
let's assume the initial value is "I" and the final value is "F."
The percent change of -56.25% means that the final value is 56.25% less than the initial value, or 43.75% of the initial value remains:
F = I - 0.5625I
= 0.4375I
Now, calculate the growth factor:
Growth Factor
= Final value / Initial value
= F /I
= 0.4375I /I
=0.4375
Therefore, the 1-unit growth factor when the percent change is -56.25% is 0.4375, which indicates a decrease of 43.75% when the quantity decreases by 1 unit.

Greek architects considered a rectangle whose length was approximately 1.6 times its width to be the most visually appealing. find the length and width of a rectangle constructed in this manner if the sum of the length and width is 130ft
Answers
Final answer:
The length and width of the rectangle constructed in this manner are approximately 64ft and 40ft respectively.
Explanation:
To find the length and width of a rectangle constructed in this manner, we can use the given information that the length is approximately 1.6 times the width and the sum of the length and width is 130ft.
Let's say the width is represented by 'w', then the length would be approximately 1.6w.
Based on the given conditions, we can write an equation: w + 1.6w = 130ft. Solving this equation, we get w = 40ft and the length is approximately 64ft.

Answers
If the slope is the same for both equations, it is most likely parallel.
If it's the reciprocal (Where you flip the number and add change the signs. For example, the reciprocal of 1/2 is -2)
If the slope is not the same or the reciprocal, then it is neither.
So for the first equation, your slope is:
3x+2y=6
2y=-3x+6
y=-3/2x+3 The equation y=mx+b can help you here, where m is the slope.
Your slope is -3/2
For the second equation, your slope is -3/2 since y=-3/2x+5 is already in y=mx+b form and m is the slope.
Since both slopes are -3/2, then you have parallel equations!
(Be careful though, sometimes it will have the same slope but there will also be the same y-intercept. If that happens, it's no longer parallel, but it's the same equation. Such as y=-3/2x+1 and y=-3/2x+1. In this case there will be infinite solutions, but parallel equations have no solutions.)

what is the area of this
Answers
The total area of the figure, calculated by summing the areas of three rectangles, is 81 square yards.
The figure in the image is composed of three rectangles. To find the total area, we calculate the area of each rectangle and then sum them up.
The first rectangle has a length of 13 yards and a width of 5 yards. Using the formula for the area of a rectangle, which is length times width, we get an area of 13 yd * 5 yd = 65 square yards.
The second rectangle extends upwards with a length of 2 yards and a width of 5 yards. Its area is 2 yd * 5 yd = 10 square yards.
The third rectangle extends to the right with dimensions of 2 yd by 3 yd. Its area is 2 yd * 3 yd = 6 square yards.
Adding these areas together, we get a total area of 65 sq yd + 10 sq yd + 6 sq yd = 81 square yards.
The question probable may be:
Find the area of the figure. (sides meet at right angles.)
The area of the piecewise rectangular figure is 59 square yards.
How the area is determined:
The first rectangle:
Length = 13 yards
Width = 5 yards
Area of the first rectangle = 65 square yards (13 x 5)
The second rectangle:
Length = 13 yards
Width = 2 yards
Area of the second rectangle = 6 square yards (3 x 2)
Since the second rectangle reduces the first rectangle, we subtract:
Area of the piecewise rectangle = 59 square yards (65 - 6)
Thus, we can conclude that the area of the piecewise rectangular figure is 59 square yards.

A drawbridge in Jacksonville, FL, allows an average of 22 boats per day to pass. What does the point (4,88) on the graph mean in this situation?
Answers
Answer: This shows, 'After 4 days, 88 boats will have passed under the bridge'.
Explanation:
Since, According to the question, Jacksonville allows an average of 22 boats per day to pass.
Thus we can say that number of boats is dependent on days and both are varying.
And, a function is the type of y=f(x), where x is independent variable while y is dependent variable.
So, we can take x for representing number of days and y for representing number of boats.
Thus, according to the question, y= 22x.
if we take 4 days i.e. x=4 then y=22×4=88
⇒It takes 4 days for an average of 88 boats.
Which is showing by (4,88) on the given graph.
