Answer:

part a: 3 6/8

Step-by-step explanation:

part a: you have to find the difference between them. if you find something like this again what I would do is do how many whole numbers there are between the two number in this case 3. then figure out what the fraction is. the fraction isn't how many spaces there are in-between but how many there are counting the final number. so from 12 to 13 there are 7 spaces plus the number 13. then you figure it out from there.

A dinner cost $28.50 which included a 15% tip. How much was the tip?

Answers

Answer: $4.28

Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Round 4.275 to the hundredths, which equals 4.27

Answer: Tip: $4.275 = $4.28

Step-by-step explanation:

Use the formula: Tip = Tip% x Bill Total

In this case, the tip is 15% and the total bill is $28.50.

15% = 0.15

28.50 x 0.15 = 4.275

Round 4.275 to the hundredths, which equals 4.27

Answer:

$4.28

Step-by-step explanation:

15%= 0.15

0.15*28.50= 4.275

Simplified: $4.28

Answer:

8 because if you take a row away from the total, you have 8, and that's how many are hidden

Step-by-step explanation:

Answer: there are eight blocks hidden in the cup.

Step-by-step explanation:

seeing that we don’t know how many blox are in the cup The cup would be a variable in this situation.

x + 4 = 12 cubes

to find your answer you would’ve solve for X, a.k.a. the cup.

x + 4 = 12 cubes

first you would do the inverse operation of addition so instead of adding four you subtract four from four, so that it cancels out. Whatever you do to one side you have to do to the other side so you would have to subtract 4 from The previous 12 cubes.

X = 12 - 4

and your final answer would be 8 cubes

x = 8

there are eight blocks/cubes hidden in the cup

what is 52/7. in need help

Answers

Answer:

52/7 is 7.42857142857 or 7.4.

Step-by-step explanation:

i need help asap!!! I can give brainlist.

Answers

1. P is the principal amount, $630.00.
r is the interest rate, 6.5% per year, or in decimal form, 6.5/100=0.065.
t is the time involved, 4....year(s) time periods.
So, t is 4....year time periods.
To find the simple interest, we multiply 630 × 0.065 × 4 to get that:
The interest is: $163.80

2. =8000 x 9 x 18
=12,960
Total amount = 12960 +8000=
$20,960
3. annual interest rate = 15.9 %
initial charge = $126
to get the annual interest paid = 15.9% of $126
= 0.159 * $126 = $20.03
monthly interest paid would be = annual interest / 12 months
= 20.03 / 12 = $1.67
hence in 2 months Rita will pay = initial charge + monthly interest * 2
= $126 + $ 1.67 *2 = $ 126 + $3.34
= $ 129 .34

4. To find the amount of money in the account after 8.5 years we will first turn 5.6% into a decimal. We'll do that by moving the decimal within the percentage two places to the left. That leaves us with 0.056.
Next, we'll multiply our factors to help us find out how much interest will be accrued within the 8.5 years.
500 x 0.056 x 8.5 = 238.
Margarito will earn $238 within an 8.5 year time frame.
Since her original deposit was $500 and assuming no other deposits/withdrawls occur within the time frame, we will add $238 of interest to the original deposit.
500 + 238 = 738.
This means, that Margarito will have $738 in her savings account after 8.5 years of just accruing interest.

5. $18,260 divided by (/) $220,000 = .083 or .08. The interest is 8%.
Because Kelli is earning $18,260 a year, you need to get the number down to a decimal (which would be the interest) So, you have to divide the smaller number by the larger number. I use
x 18260
____ _______
100 % 220000
multiply 100x18260 and then divide by 220000. You get 8.3, or 8.3%, but if you round up, you get 8%.

1. 163.80
2. 12,960
3. 3.34
4. 738
5. 8.3%

"Hmm. This isn't right," she thought. As she walked to her desk, she noticed that severalstudents were huddled around Leo's desk and that he had red rings around his eyes. He looked upat Hannah and said, "Why are people so mean?" Hannah didn't know what to say and stopped asLeo put his head into his hands. "Are you okay, Leo?" Hannah asked. She knew it was a silly thingto ask; he obviously wasn't okay at all. One of the other students said, "Someone postedsomething nasty about Leo online last night. He's just seeing it now."Hannah felt nauseated. Things like this had happened at her school before, and she knewthat they never ended well. Leo had a very good question. Why are people so mean? That was areal mystery. Someone probably posted something online thinking it to be funny. They didn't thinkabout how Leo would feel when he found out, and they obviously didn't think about how it wouldfeel if anyone did that to them.Just then, the principal walked into the class looking stern and angry. "Will and Emily. Myoffice. Now!" he barked. The two students kept their heads down as they gathered their bags andleft the room, desperate not to look at anyone as they left. Hannah realized that they were alreadyembarrassed about what they'd done. Maybe they were already thinking about how upset theirparents would be when they found out from the principal exactly how callous, thoughtless, andmean they'd been.No one saw Will and Emily at school again that day.The next morning, when Hannah got to her classroom, she saw everyone standing outside,gazing at the lockers. As she approached, she noticed that people were smiling and laughing.There were colored sticky notes on each of the lockers. As she got closer, she began to smile - thepositive energy was contagious, and she hadn't even seen what was on there yet. Each locker had at least two sticky notes on the door. Some sticky notes had silly jokes;some said things like, "What do you call a dinosaur who likes words? A Thesaurus!" Others hadpositive statements, such as, "You are truly wonderful!" Everyone was reading each other's lockernotes and sharing the jokes. Hannah joined in and was pleased to see Leo laughing along witheveryone else. At one point, someone said, "Mine says I am clever and funny," and Leo replied, "No,it says ... ", and then didn't finish his sentence. No one else noticed, but Hannah thought this was abit strange. She caught Leo's eye and smiled at him. He smiled back before turning to someoneelse.Hannah thought about Sherlock Holmes's words. The art of investigating is in seeing whatothers don't see. All of her classmates were looking at the lockers when someone said, "Who didthis?" No one owned up, but everyone kept smiling.It took a while before people realized that Will and Emily were now on the outskirts of thegroup, trying to get to their lockers. Both of them were obviously still humiliated by their actions.Hopefully they regretted their actions. Their heads were bowed, and they didn't try to talk toanyone. Hannah saw them look at the sticky notes on their lockers. On both of them it said, "Be thebest person you can be!" No one else had the same message on his or her locker, apart from Willand Emily. Just then, everyone else moved into the classroom. Just before she went in, Hannahheard Leo say good morning to them both before he went in. Emily and Will looked surprised, notjust at their lockers, but at Leo's greeting, too.When their teacher arrived, he said, "The lockers look great, but I don't think this shouldhappen every day. Does anyone want to own up to this? No? Okay, let's just leave it then." Hannahcaught Leo's eye. He looked at her, gently nodded his head toward her, and smiled. Then he put hisfinger to his lips and looked away. Hannah realized that she'd solved her second mystery, but thistime, she didn't need to share her achievement with others. What Leo had done was very special,and maybe one day, she'd talk to him about it. One day, but not today. You read three mysteries about Hannah, the eleven year old detective.
