Answer to number 1: You would chose the even numbers because there are more even numbers and two odd numbers equals an even number. There is a less chance to get an odd number. Answer for number 4: You would need a total of 1,369 cubes. To get the answer multiply 37*37 because the number of steps are squared to equal the number of cubes. If you have the number of cubes then you would find the square root to get the steps. Ex: 9 cubes would equal to 3 steps, 16 cubes equals 4 steps. If you have 16 steps you have 256 cubes.

How may different arrangements are there of the letters in ALASKA? 7 of 10 (5 complete) HW Score: 26.15% E Que The number of pos

Lubov Fominskaja [6]

<h2>Answer:</h2>

The number of possible arrangements is : 120

<h2>Step-by-step explanation:</h2>

We know that in order to find the different arrangements which are possible we need to use the method of permutation.

The arrangement of a given word is calculated as the ratio of the factorial of number of letters to the product of factorial of numbers the number of times each letter is repeating.

The word is given to be:

ALASKA

There are a total of 6 letters in the given word

Out of which a letter "A" is repeating 3 times.

Hence, the number of arrangements possible are:

$=\dfrac{6!}{3!}\\\\\\=\dfrac{6\times 5\times 4\times 3!}{3!}\\\\\\=6\times 5\times 4\\\\\\=120$

On Monday, a factory used 11/15 a ton of grapes to make grape juice. Tuesday required 14/30 a ton more than the amount on Monday

Rudiy27

Answer:

1 ton on wednesday!

Step-by-step explanation:

We need to go step by step for this one.

On monday the factory used 11/15 of a ton, while tuesday required 14/30 a ton more than that. To find tuesday's amount we must take 11/15 and add 14/30 to that.

11/15 + 14/30 = 1 1/5

Tuesday = 1 1/5 of a ton

On wednesday the factory uses 5/6 of the amount used on tuesday, which is 1 and 1/5 of a ton.

1 1/5 times 5/6 = 6/5 times 5/6

Anything multiplied by their reciprocal is 1, so the answer is 1. On wednesday 1 ton of grapes was used on wednesday!

Five years ago, a typical 70” TV cost about $2400. Now a similar TV costs approximately $1680. What is the percent decrease in T

Archy [21]

Answer:

The percentage decrease in TV price after five years is 6.89

Step-by-step explanation:

Given as :

The cost of TV five years ago = $ 2400

The present cost of TV = $ 1680

Let The decrease percentage in five years = x

So, The cost of TV after T year = Present cost × $(1-\frac{Rate}{100})^{Time}$

Or, $ 1680 = $ 2400 × $(1-\frac{Rate}{100})^{5}$

Or, 0.7 = $(1-\frac{Rate}{100})^{5}$

Or, $(0.7)^{\frac{1}{5}}$ = 1 - $\frac{x}{100}$

Or, 0.9311 = 1 - $\frac{x}{100}$

Or, $\frac{x}{100}$ = 1 - 0.9311

∴, $\frac{x}{100}$ = 0.0689

I.e x = 0.0689 × 100 = 6.89

Hence The percentage decrease in TV price after five years is 6.89 Answer
