Single digit primes are 2, 3, 5 and 7. Only 3 is 3-primable
Two digit numbers that are 3-primable are
27, 33, 57, 72, 75
The 3 digit numbers that are 3-primable are
222, 333, 555, 777
225, 252, 522
237, 273, 327, 372, 723, 732

The cost of 24 bottles of water is $6. Which expression shows how to find the cost of 10 bottles of water?
yaroslaw [1]
So first you need to find out how much one water bottle cost. 
6/24= 0.25 
Okay now you need to find how much it would cost for 10. 
so you would times 10 by $0.25: 
10*0.25= $2.50 
So $2.50 would be you answer. 
Hope that helps!!

Jonathan can throw a baseball 10 1/3 yards. His brother Joey can throw a baseball 13 1/2 yards. How much father can Joey throw t
butalik [34]

let's firstly convert the mixed fractions to improper fractions, and then subtract.


\bf \stackrel{mixed}{10\frac{1}{3}}\implies \cfrac{10\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{31}{3}}~\hfill \stackrel{mixed}{13\frac{1}{2}}\implies \cfrac{13\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{27}{2}} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \cfrac{27}{2}-\cfrac{31}{3}\implies \stackrel{\textit{using the LCD of 6}}{\cfrac{(3)27~~-~~(2)31}{6}}\implies \cfrac{81~~-~~62}{6}\implies \cfrac{19}{6}\implies 3\frac{1}{6}

The waiting times between a subway departure schedule and the arrival of a passenger are uniformly distributed between 0 and 8 m
rusak2 [61]

Answer:

0.59375

Step-by-step explanation:

In a uniform distribution the probability that the time t is greater than any given value, X, is:

P(t\geq X)=1-\frac{X}{b-a}

In this problem, the limits of the distribution are a = 0 and b = 8 minutes.

For X =3.25 minutes:

P(t\geq 3.25)=1-\frac{3.25}{8-0} \\P(t\geq 3.25)=0.59375

The probability that a randomly selected passenger has a waiting time greater than 3.25 minutes is 0.59375.

According to all known laws
of aviation,

there is no way a bee
should be able to fly.

Its wings are too small to get
its fat little body off the ground.

The bee, of course, flies anyway

because bees don't care
what humans think is impossible.

Yellow, black. Yellow, black.
Yellow, black. Yellow, black.

Ooh, black and yellow!
Let's shake it up a little.

Barry! Breakfast is ready!

Ooming!

Hang on a second.

Hello?

- Barry?
- Adam?

- Oan you believe this is happening?
- I can't. I'll pick you up.

Looking sharp.

Use the stairs. Your father
paid good money for those.

Sorry. I'm excited.

Here's the graduate.
We're very proud of you, son.

A perfect report card, all B's.

Very proud.

Ma! I got a thing going here.

- You got lint on your fuzz.
- Ow! That's me!

- Wave to us! We'll be in row 118,000.
- Bye!

Barry, I told you,
stop flying in the house!

- Hey, Adam.
- Hey, Barry.

- Is that fuzz gel?
- A little. Special day, graduation.

Never thought I'd make it.

Three days grade school,
three days high school.

Those were awkward.

Three days college. I'm glad I took
a day and hitchhiked around the hive.

You did come back different.

- Hi, Barry.
- Artie, growing a mustache? Looks good.

- Hear about Frankie?
- Yeah.

- You going to the funeral?
- No, I'm not going.

Everybody knows,
sting someone, you die.

Don't waste it on a squirrel.
Such a hothead.

I guess he could have
just gotten out of the way.

I love this incorporating
an amusement park into our day.

That's why we don't need vacations.

Boy, quite a bit of pomp...
under the circumstances.

- Well, Adam, today we are men.
- We are!

- Bee-men.
- Amen!

Hallelujah!

Students, faculty, distinguished bees,

please welcome Dean Buzzwell.

Welcome, New Hive Oity
graduating class of...

...9:15.

That concludes our ceremonies.

And begins your career
at Honex Industries!

Will we pick ourjob today?

I heard it's just orientation.

Heads up! Here we go.

Keep your hands and antennas
inside the tram at all times.

- Wonder what it'll be like?
- A little scary.

Welcome to Honex,
a division of Honesco

and a part of the Hexagon Group.

This is it!

Wow.

Wow.

We know that you, as a bee,
have worked your whole life

to get to the point where you
can work for your whole life.

Honey begins when our valiant Pollen
Jocks bring the nectar to the hive.

Our top-secret formula

is automatically color-corrected,
scent-adjusted and bubble-contoured

into this soothing sweet syrup

with its distinctive
golden glow you know as...

Honey!

- That girl was hot.
- She's my cousin!

- She is?
- Yes, we're all cousins.

- Right. You're right.
- At Honex, we constantly strive

to improve every aspect
of bee existence.

These bees are stress-testing
a new helmet technology.

- What do you think he makes?
- Not enough.

Here we have our latest advancement,
the Krelman.

- What does that do?
- Oatches that little strand of honey

that hangs after you pour it.
Saves us millions.

Oan anyone work on the Krelman?

Of course. Most bee jobs are
small ones. But bees know

that every small job,
if it's done well, means a lot.

But choose carefully

because you'll stay in the job
you pick for the rest of your life.

The same job the rest of your life?
I didn't know that.

What's the difference?

You'll be happy to know that bees,
as a species, haven't had one day off

in 27 million years.

So you'll just work us to death?

We'll sure try.

Wow! That blew my mind!

"What's the difference?"
How can you say that?

One job forever?
That's an insane choice to have to make.

I'm relieved. Now we only have
to make one decision in life.

But, Adam, how could they
never have told us that?

Why would you question anything?
We're bees.

We're the most perfectly
functioning society on Earth.

You ever think maybe things
work a little too well here?

Like what? Give me one example.

I don't know. But you know
what I'm talking about.

Please clear the gate.
Royal Nectar Force on approach.

Wait a second. Oheck it out.

- Hey, those are Pollen Jocks!
- Wow.

I've never seen them this close.

They know what it's like

The Johnson twins were born nine years after their older sister. This year, the product of the three siblings" Ages is exactly 2
larisa [96]

Answer:

ages of the twins are 11 years

Step-by-step explanation:

let the age of the twins each be X

Age of the older sister = X+9

This current year;

(X)(X)(X+9) - (X+X+X+9) = 2378

X³+9X² - 3X-9 = 2378

Solving the polynomial

X = 11

Hence ages of the twins are 11 years
