Answer:

1. ¡Cómela!

2. ¡Hazlos!

3. ¡Lávala!

Explanation:

Convert 237 into binary system​
Daniel [21]

Hey there,

I think I may have the answer you are looking for.

Your answer: 11101101

Here are step-by-step instructions on how to convert the decimal number 237 to a binary number.

Step A) Determine if 237 is an even or odd number. If it is even, you assign a 0 and if it is odd you assign a 1.

Step B) Deduct the 1 or 0 in step A from 237 and then divide it by 2. Then, you see if that number is even or odd and then assign a 0 or 1 like step A.

Step C) Repeat step B with the new number until the number you get is 1.

Step D) Put all the 0s and 1s you assigned in reverse order to get the answer.

To illustrate better, we detailed below how we converted 237 decimal to binary using the steps above.

237 → 1

(237 - 1)/2 = 118 → 0

(118 - 0)/2 = 59 → 1

(59 - 1)/2 = 29 → 1

(29 - 1)/2 = 14 → 0

(14 - 0)/2 = 7 → 1

(7 - 1)/2 = 3 → 1

(3 - 1)/2 = 1 → 1

Then you put the binary number above in reverse order and you get the answer: 11101101

I have spent a long time on this answer so please mark it.

Cheers, Jake :)

Ella wrote an opinion piece about eating corn on the cob.
Anastaziya [24]
I think the Answer is A

Explanation:

You’re asking which sentence in the passage explains why she thinks it’s messy......

The reason it’s not B is because she doesn’t justify if it’s messy.. she only says it’s hard

It’s not c because she just isn’t holding it right

And it’s not D because;; just because a lot of people like to eat corn on the cob doesn’t mean it’s messy...

Sorry if it’s not right
