What's your question????

Just like this.......(4+5/8)/2

Then, hit "="

how many numbers between 1 and 100 (inclusive) are divisible by 3 and 5.

-----------------------------------------------------------------------------------------------------------------------------

Since 3 and 5 are relatively prime (they have no common divisors except 1) this should be easy to determine.

The first multiple of 3 and 5 is 15 = 3*5*1 = 15*(1)

The second one is 30 = 3*5*2 = 15*(2)

Then by solving this inequality....... 15(n) ≤ 100....you should be able to determine how many numbers between 1 and 100 (inclusive) are divisible by 3 and 5. If you get a "remainder," just ignore it - "n" is an integer.

(-2.9 + 4.4)a + (6.8 - 7.3) = 3.9a - 2.9

$$radians = \pi \dfrac {degrees} {180}$$

$$x^{-a} = \dfrac 1 {x^a}$$

other than that I'm not sure what you are asking.

a book falls off the top of an 8-foot shelf. Theodore is 4-feet tall. if is takes theodore 2 seconds to respond to the fall and get out of the way, does the book hit him?

Let's see how much Physics I can remember.

The position "y"  of any object at time t is given by:

y = -16t² + v_ot + h

Where v_o is the original velocity ( 0, in our case) and h is the original height (8 ft.). Note that y = 4 feet above the ground. So we have...

4 = -16t² + 8  which simplifies to

0 = -16t² + 8  and solving for t, we get

t = ± (1/2) second

Rejecting the negative, we get that the book falls 4 ft. in (1/2) second !!

Move faster, Theodore !!

3.14 is pi

What is the quotient of (9.184×10−4)÷(2.87×10−2) written in scientific notation?

----------------------------------------------------------------------------------------------------------------------------

So we really have  (9.184/2.87) X (10^-4/10^-2)

This simplifies to (3.2) X (10²) /(10⁴) =

(3.2) X 10^-2

And that's it.........

Do you mean 9 times the square root of 3?

If that's the case, just put in:

9* sqrt(3)

The calculator on this website also has buttons for inputting roots and powers of numbers. Just click/type in the number, then click the button:) 

what is the next atep in solving this equation?.... 61=3341-2900cosX 

you are solving for X

---------------------------------------------------------------------------------------------------------------------------

OK......first, let's subtract 3341 from each side   This gives

-3280 = -2900cosX

Divide both sides by -2900   We have

1.131 = cosX

Do you see the problem here??

The cosine function only returns values between -1 and 1, inclusive.

Thus, this problem has no solution !! 

60mm in cm

----------------------------------------------------------------------------------------------------------------------------

There are 10 mm in each cm

Then

60mm x (1cm)/(10 mm) = 6 cm  (The mm units "cancel" each other out, and I'm just left with cm)

yus just use yo feet. grip it wid da toez

60mm in cm would be 6 cm. just divide the number of mm by 10 to convert to cm.

you must move back instead of forward. if i remeber correctly, then you divide multiple times. Sorry its kinda hard to explain. if you didnt find this useful, just google it.

True, because:

66 2/3% of a number is the same as 2/3 of it, so

A  66 2/3% decrease of the number (say, x) would be:

1x - (2/3 * x) 

Which would equal: 

1/3x

Therefore, one third of a number is a 66 2/3% decrease of a number.

Greg made 9 gallons of chili dinner.Each bowl can hold 2 full ladles of chili.A full ladle holds 10 ounces. what is the greatest number of bowls he can fill with chili?

----------------------------------------------------------------------------------------------------------------------------

Well....if he just dumped all of it into my SuperSized bowl, we wouldn't have to worry about it !!

OK....I'll get serious......

Let's see...each bowl holds 20 ounces (2 ladles full)

If we're in the U.S., we have 128 ounces to a gallon. So 9 gallons X nimber ounces in each gallon (128) = 1152 ounces. So dividing 1152 ounces by the number of ounces each bowl will hold (20), we get 57.6 bowls.

If we're in the U.K., we have 160 ounces to a gallon. So 9 gallons X nimber ounces in each gallon (160) = 1440 ounces. So dividing 1440 ounces by the number of ounces each bowl will hold (20), we get 72 bowls!!

Moral of the story........I'm moving to the U.K.

csc138 degrees 23 inches

-----------------------------------------------------------------------------------------------------------------------------

I believe you have been asked to find this:   csc (138°0′23″)

The little   ″   means "seconds" (not "inches")......To be fair, I always wondered why this symbol was adopted, too!!  It IS a little confusing, if we don't know the context!!

Well, anyway....1 second = 1/3600th of a degree. We need to find a decimal value for 23 of them.

That's easy...it's just 23 x (1/3600) = .00639

Now....we're ready to rock and roll!!

So, we want to find csc(138.00639°)

And, using the on-site calculator, we have:

csc(138.00639°) ≈ 1.49

Also, note that the  ′ symbol means "minutes" (not "feet")    1 minute = 1/60th of a degree

Hey.....good thing they didn't divide degrees up into "yards," as well, huh??? I don't know what symbol we could have used for that !!

I think that's all ....  

a triagle is not a shape that exists

If you like the equation solved for x, the answer is x=(y+5)/4. however, if you would like it solved for y, then the answer is y=-5+4x. If there are initial conditions given for this problem, then they can be plugged in to get a specific number answer for the equation

a^b=b where a and b are different numbers

-----------------------------------------------------------------------------------------------------------------------------

Let a = √(2) .....let b = 2

Then....... (√(2))² = 2

Note that a, b ARE "different," since √(2) ≠ 2

(You didn't specify that "a" had to be an integer, only a "number"!!) 

54,100,000 can be rewritten as 5.41*10^(7). An easy way to conver to scientific notation in the future is to simply take the decimal place, which is at the end of the number, and shift it left, count up as you go, until a singal digit remains on the left side. Then multiply this new number by 10^(n), where n is the number of places over you counted. This works for small numbers as well such as .000000541, which would be 5.41*10^(-7). Simply move the decimal to the right and remember to put a negative sign in front of the n
