I cant really figure it out even though I sing the 7 song like this"7,14,21,28,35,42,49,56,63,73. I dont know what else to do.So what should I do?

Kaitlyn

Divide by using pencil and paper...

or use google.

and i believe it is 8 and 2/7

First of all you need a scientific calculator, one with sin cos, tan, log etc. If you do have one, look for a key marked **EE **(Texas Instruments) or **x10^x** (Casio) or **EXP (Casio, Sharp, Canon).**

To enter 5.10*10^(-7) ,

type in 5.10[EXP] (-)7 then ?nter, Exe, or =.

Both numbers are even, so let's start by dividing by 2.

$9.08 to $8.24

Both numbers still even, divide by 2 again.

$4.54 to $4.12

Both numbers still even, divide by 2 again!

$2.27 to $2.06

One number is not even, so we don't need to divide by an even number again.

To see if 3 goes into the numbers evenly, add up the digits of the number and see if 3 goes into the total evenly. If yes, the number is divisible by 3.

2+2+7= 11, 1+1 = 2. 3 does not go evenly into 2, therefore 3 does not go evenly into $2.27.

Numbers don't end in 0 or 5, so 5, 10 and 15 do not go into them evenly.

7 does not go in evenly

To see if 9 goes into the numbers evenly, add up the digits of the number and see if 9 goes into the total evenly. If yes, the number is divisible by 9.

We added up the digits and got 11, so 9 does not go in evenly into $2.27.

See if 13 goes into the numbers evenly. No.

See if 17 goes into the numbers evenly. No.

When do we stop? 17 squared is 289, which is higher than both numbers so we can stop!

We have the number in lowest terms at $2.27 to $2.06.

Good luck.

Make sure your calculator is set to the desired angular mode.

The quotient of 120 divided by the tangent of 68 radians is about -58.82, as your calculator is giving you.

The quotient of 120 divided by the tangent of 68 degrees is about 48.48 . The quotient of 120 divided by the tangent of 68 grads is about 65.97 .

This calculator does not have a key that you can use to find the prime factor of an integer.

You can however use the calculator to find the factors

1.** If number is even divide it by 2**

Keep dividing by 2, while keeping track of how many times you divided by 2.

If you divided 5 times by 2 before getting an odd number, then your first factor is 2^5

2.**Now try dividing by 3**, keep track of the number of times you divided by 3 before you could not divide by 3 any more. If you divided 0 times by 3, your second factor is 3^0, or 1 and 3 is not a factor.

If you divided 4 times by 3, your second factor is 3^4

3.**Divide by 5,** until you can't any more. Keep track of the number of times you divided by 5.

4. Divide by all other prime numbers 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, etc. For each prime number, keep track of how many times you divided by it, until you could not any more.

**Example: 23100**

*Division by 2*

23100/2=11550 ---------> 1 division by 2

11550/2=5775 ----------> 2 divisions by 2

Note that 5775 is not divisible by 2.** No more divisions by 2. **

First factor is 2^2

*Division by 3:*

5775/3=1925 ----------> 1 division by 3

1925/3=641. 66667 Not an integer. No more divisions by 3.

**2nd factor is 3^1**

*Division by 5 (number ends in 5)*

1925/5 =385 -------> 1 division by 5

385/5=77 ----------> 2 divisions by 5 and no more (quotient does not end in 0 or 5)

**3rd factor is 5^2**

*Division by 7 *

77/7=11 --------> 1 division by 7, and no more

**4th factor is 7^1=7**

*Division by 11*

11/11=1

**5th factor is 11^1=11**

Assembling the factors 2^2, 3^1, 5^2, 7, 11

Prime factorization of 23100 is

**23100=(2^2)(3)(5^2)(7)11**

Without knowing exactly what you're doing I can't be sure, but I suspect you're entering the 10^9 as something like 1 0 EE 9 .

1 0 EE 9 gives you 10 * 10^9, which is 10^10. You should be doing this as 1 5 0 0 / 1 EE 9 = .

It is unclear whether your equation is:

a: ((SQRT61) - 7) / 2

or

b: ((SQRT61) / 2) - 7

For a:

Type 61 SQRT.

Subtract 7.

Equals.

Divide by 2.

Equals. (Should be 0.4051248...)

For b:

Type 61 then SQRT.

Then divide by 2.

Equals.

Then subtract 7.

Equals. (Should be -3.094875...)

Good luck.

You do it with lots of parentheses.

Type ((58+2/3)*(18+1/2)*(3/4))/27

Then press MATH button then 1 to get the frac. Then press ENTER. You should get 814/27.

Type ((58+2/3)*(18+1/2)*(3/4))/27

Then press MATH button then 1 to get the frac. Then press ENTER. You should get 814/27.
