Answer:
We can easily see that 45% is larger than 1/3, so the second option is better, and to calculate it 45 percent of 90 is 40.5, and 1/3rd of 90 is 30, so Laura would pay 49.5 and 60, the 2nd option would have her pay 10.5 dollars less than the 1st option

Answer:
37.5
Step-by-step explanation:
First you have to realize that these are similar triangles.
You can do a easy cross multiplication with these types of questions by forming an equation with the similar angles.
put the smaller above the decimal and the bigger one below like this.
[tex]\frac{8}{25}[/tex]=[tex]\frac{12}{x}[/tex]
Now cross multiply
8x=300
x=37.5

The area of ABC is 72 square centimeters. find area of DEF
Answer:
800
Step-by-step explanation:
Set up your proportion first (6/20 = 72/x). Then, square 6 and 20 (36/400 = 72/x). Cross multiply and divide (36x = 28800). Divide 28800 by 36 and that gives you 800 as your answer.

In its first two months, a small business had profits of -$402 and -$390. If
the total profit for the first five months was -$1038, what was the average
profit for months 3-5? Show your work.
Answer:
-$82
Step-by-step explanation:
-402 + -390 = -792
-1038 - -792 = -246
Since you are trying to find it for the remaining 3 months you divide by 3.
-246/3 = -$82

A student need to fill a tank with 9 liters of water. How many 1/3 liters will it take to fill the tank?
Answer:
Number of [tex]\frac{1}{3}[/tex] liters required to fill the tank = 27
Step-by-step explanation:
Amount of water needed to fill the tank = 9 liters
Measure of water to fill a vessel = [tex]\frac{1}{3}[/tex] liters
Number of [tex]\frac{1}{3}[/tex] liters vessels required to fill the tank = [tex]\frac{9}{\frac{1}{3}}[/tex]
= 9 × [tex]\frac{3}{1}[/tex]
= 27
Therefore, number of [tex]\frac{1}{3}[/tex] liters required to fill the tank = 27

Exponents that are the being raised by another exponent get multiplied, so 6 times -3 is -18.
When a number/variable has a negative exponent, the number/variable will be put under 1, and the exponent will change to be positive.

Write a function to represent the set of ordered pairs.
{(2, -1), (4, 5), (6, 15), (8, 29)}
Step-by-step explanation:
ES6 has a new Set data structure for storing sets of unique objects. However it is based on object references as opposed to value comparisons. As far as I can tell this makes it impossible to have a set of pairs of numbers without stringifying.
For example, typing in Chrome's console (needs Chrome 38+):
> var s = new Set(); < undefined > s.add([2, 3]); < Set {[2, 3]} > s.has([2, 3]) < false <--- was hoping for 'true'
This appears to be by design: since I passed a different array of [2, 3] to has(), it returns false, because although the contents is the same it only looks at object references, and I allocated a new and different array to pass to has(). I would need to store a reference to the original array I passed to add() to check with has(), but this is not always possible. For example if the number pairs represent co-ordinates, I might need to check if the set has [obj.x, obj.y], but this will always return false since it allocates a new array.
The workaround is to stringify the arrays and key on strings like "2, 3" instead. However in something performance-sensitive like a game engine, it is unfortunate if every set access needs to make a string allocation and convert and concatenate number strings.
Does ES6 provide any feature to solve this problem without stringifying, or is there any feature on the horizon with ES7 that could help as well?

As you've noted [2, 3] === [2, 3] is false, meaning you can't use Set like this; however, is Set really the best option for you?
You may find that using a two-level data structure like this will be better for you
var o = {}; function add(o, x, y) { if (!o[x]) o[x] = {}; o[x][y] = true; } function has(o, x, y) { return !!(o[x] && o[x][y]); } function del(o, x, y) { if (!o[x]) return; delete o[x][y]; // maybe delete `o[x]` if keys.length === 0
its a angle question.
