Look down For link!

Cmon half way there

jkjk

First part (tip amount)

$6.26

Second part (Total bill)

$41.04

Step-by-step explanation:

Well to find the percentage of a number, convert the percent into a decimal which is basically moving the decimal place 2 places to the left. THen you multiply that amount by the original number an din this case you would get 6.2604. You round that to the nearest penny (or hundreths) and you;d get $6.26. Thats the first part

The second part is simple, you add the tip with the total bill and you would get $41.04.

Eugenia gasto 10 euros en el quiosco, compro 5 bocaditos, un paquete de galletas que costaba 1 euro y pagó 4 euros que debia ¿cuanto cuesta cada bocadito?

Answers

Answer:

the each snack cost is 1

Step-by-step explanation:

Let us assume the each snack cost be x

So according to the question

The following equation would be applied

5x + 1 + 4 = 10

5x + 5 = 10

5x = 5

x = 1

hence, the each snack cost is 1

So the same would be considered and relevant too

The water used by the 12 students during the experiment was poured from a beaker after the water was poured 1/4 gallon of water was left in the beaker What was the total number of fluid ounces of water in the beaker before the water was poured by the 12 students

Answers

Answer:

128 fluid ounces

Step-by-step explanation:

We were told that:

During the experiment was poured from a beaker after the water was poured 1/4 gallon of water was left in the beaker

Hence, this means that the total gallon of water in the beaker is 1 gallon

Convert 1 gallon to fluid ounces

1 gallon =128 fluid ounces

Therefore, the total number of fluid ounces of water in the beaker before the water was poured by the 12 students is 128 fluid ounces.

It was a dark quiet night, Halloween night when Celestia screamed. Celestia was a dragon human hybrid with dark blue hair and kind light blue eyes, dark blue wings, a dark blue tail, her hair was always in what looked like two buns on top of her head the little bit of hair that was too short-covering her ears with her bangs shadowing her face, she was in a witch costume that was black dark purple and dark pink with a black hat. Nikki came running her longish white and purple hair in a messy bun, she was wearing her mad scientist costume but the fake blood looked suspiciously realistic. Wannabe ran in looking like the human form of sans along with Angel a few feet behind him dressed as a fairy. Nikki stood staring trying not to cry. Nikkis friend Emery came in wearing her police uniform on and blue blonde hair up in a ponytail along with Rihanna in her outfit that she wore at her concert the night before, the light baby blue costume made her light pink eyes stand out and her fox tail nearly invisible under a big black bow, her hair in ponytails right behind her fox ears. The two stared in horror at what seemed to have happened, one of their friends had been brutally murdered but their face was unrecognizable from the damage. Nikki stood up and took ad headcount matching names with faces until she realized who it was. Im going to find the person who did this and make them pay, Nikki said in a dark evil angry voice, she was mad and near her breaking point. Nikki left the room unable to look at her friend lying there dead while everyone else looked at each other. Kind convenient YOU found him like this Celie Rihanna said to Celestia glaring at her, the two never liked each other and were always fighting. First of all, I couldnt handle the blood. Second of all, thats my friend! Why would I hurt him!?!? Celestia snapped, angry she was accused of the crime. You found him like this. That's a little suspicious dont you think? Rihanna said giving Celestia looks. I hate to say this but Nikki could have been faking the blood on her costume looks a bit too realistic Angel said her voice trailing off, she hated to accuse Nikki but at this point, they were all suspects except for Angel. She had said before that she'd never been able to kill someone and get away with it shed end up admitting she did it. Nikki came back in a completely different costume, her Sara Sanderson costume to be exact. Why did you change costumes? Angel questioned Nikki, changing costumes because there was what looked like blood on the other was suspicious. You act like I can choose to wear only one costume, heck Ill probably end up wearing a cosplay before we figure out who did this, Nikki answered, it was true Nikki tended to wear up to ten outfits a day so why would today be any different? Emery glared at Nikki, she didnt believe her story. Seems pretty convenient she had to change costumes so soon... She thought suspecting Nikki was hiding something. Lets do this Danganronpa style! Angel shouted, she had always thought how they did the class trials on that anime and in the game was cool. Everyone got to a podium and glared at one another. I was passing out candy to the trick-or-treaters, Rihanna said then turning her head to Celestia who was on her left. I was in the Bathroom, Celestia said, nobody was going to question her now. I was fixing my fursuit, one of the ears fell off, Nikki said with the tail to her fursuit in hand. I was outside sitting on the porch, Emery said pointing at the door. Im too dum.b to pull something like this off you guys know this, Angel stated honestly, she wasnt the brightest bulb. I was in the kitchen when I heard someone yell for help. Wannabe said solemnly.
