\(-\frac{5}{9}\) is not a irrational number.

Divide them to get .83333333333333333333333333 and it would be 83% for short

\(\frac{10}{12}\)into a percent

\(\frac{10}{12}\times100\)

\(0.833333333333333...\times100\)

Ya you are

Hi Matt, you have asked me to comment on this so I will.

This is a international forum.  I am from Sydney, New South Wales, Australia. 

All our schools teach Calculus.  Students do not have to take it of course but any student who intends to have a science type degree is encouraged very strongly to do Advanced or extension mathematics.  These are 2 year courses and I'd say approximately 1 of those years is entirely calculus.  :)

donno. i know the answer tho. its 42.

If a ship's path is mapped on a coordinate grid, it follows a straight-line path of slope 5 and passes through point (2, 3).

Part A: What is the equation of the path?

Part B: Does the ship pass through point (6, 25)?

Part C: A second ship follows a straight line, with the equation x + 5y − 15 = 0. Are these two ships sailing perpendicular to each other? Justify your answer.

A) Equation  of the ship's path is

y - 3 = 5(x - 2)

y - 3  = 5x - 10      add 3 to both sides

y =  5x - 7

B)  (6, 25)  ???

Put 6 in the equation and see id it produces 25...so we have.... 

y = 5(6) - 7   =   30 - 7   = 22   =  point (6, 22)

So...it does not pass through the point   (6,25)

C)  x + 5y - 15 = 0

Rearrange as

5y  = -x + 15     divide both sides by 5

y = (-1/5)x + 3

Yes....the ships are sailing on perpendicular pahs because the slope in the equation of the second ship's path is the negative reciprocal of the slope in the equation of the first ship's path.

In mathematics, the logarithm is the inverse operation to exponentiation. That means the logarithm of a number is the exponent to which another fixed value, the base, must be raised to produce that number. In simple cases the logarithm counts repeated multiplication.

Incase you didn't know the highlighted word:

Exponentiation is an expression that involves exponents. When the base is a positive integer, exponentiation is also a mathematical operation that involves a finite number of multiplication problems involving the same number or variable. For example: 2*2*2*2*2.

This is from Google, since I haven't learned it yet! :)

A linear equation is an equation between 2 variables that gives a straight line when plotted on a graph

Example: y = 2x+1

Thank you, CPhill! :)

160/3 x 3.14

For this, you can either change the fraction to a decimal, or change the decimal to a fraction. Since 160/3 is repeating as a decimal, I'm going to change 3/14 into a fraction

3.14 = 314/100

Plug it in

160/3 x 314/100

Multiply across

50240/300

Simplify

628/15

There's your answer!

Good answer, saseflower....!!!

We have 3 choices for each ball, and each choice is independent. So 3^6 = 729 ways to place the b***s.

tan y = 8/15

Since you don't know the angle, you use inverse tangent!

It looks like this:

tan^-1

So, your equation would become:

tan^-1(8/15)=y

Then solve for y! The y would be the angle

Hopefully this helps. :)

WRONG. im sorry, but WRONG. that would be the coorect answer for this problem though: 

How many ways are there to put 6 b***s in 3 boxes if the b***s are distinguishable and the boxes are distinguishable? 

now THAT would be 729.

It is possible to take the square root of a negative number, but you don't get a real number.

If you can write the number whose square root you want as the product of two equal factors, the square root of that number will be one of those factors. For example, 4 = 2*2, so the square root of 4 is 2. Every positive number has two square roots: a positive square root and a negative square root. The symbol √n is taken to mean the principal or positive square root. The cube root of a number (positive or negative) is one of three equal factors of that number, so 3√27=3, since 27 = 3*3*3. Similarly, 3√−8=−2 since -8 = (-2)(-2)(-2). Real numbers have only 1 real cube root.

These aren't my words!! I just copied and pasted, since I honestly had no idea either. :) It's been a while! Hopefully this helps

Here might be an even easier solutiion :

Let B be her base salary, C be the commission, S be the total sales for a particular month, and E be her earnings for the month

Thus, we have

B + C*(S)   = E      ...and....we have this system for the two months

B + C*(405000)  =   31200    (1)

B + C*(600000)   =  39000    (2)

Subtract (1) from (2)

C* (195000)  = 7800       divide both sides by 195000

C = 7800/ 195000  = .04  = 4%  = her commisiion

34 x 3/8

Turn 34 into a fraction

34/1 x 3/8

Multiply across

102/8

Simplify

51/4

There's your answer!

-2x-10=12

-2x=22

x=-11

2(-x - 5) = 12

Distribute

-2x - 10 = 12

Add 10 to both sides

-2x = 22

Divide by -2 on both sides

x = -11

(3x+1)(3x+1)

9x²+3x+3x+1

9x²+6x+1

x=3 x=3

     or

x=3 multiplicity of 2 

SORRY, ANSWER #2 WASN'T MEANT FOR YOU!!!!.

I'm procastining on studying for the GAMSAT so why not. 

Do you know how to do basic addition? 

7 + 7 = 14. 

7 + 7 + 7 = 21

7 + 7 + 7 + 7 = 28

Multiplication is simply a quick way of adding numbers together. 

So 7 x 4 = 7 + 7 + 7 + 7

It is simply asking you to add 7 four times. 

Here is a more elegant solution to this problem:

Let her salary be=x

Solve for x:
(39000-x)/(31200-x) = 40/27

Cross multiply:
27 (39000-x) = 40 (31200-x)

Expand out terms of the left hand side:
1053000-27 x = 40 (31200-x)

Expand out terms of the right hand side:
1053000-27 x = 1248000-40 x

Subtract 1053000-40 x from both sides:
13 x = 195000

Divide both sides by 13:
Answer: |  x = 15,000. This is her salary, so that:

31,200 - 15,000=16,200 This is her commission for Jan.2014. Therefore:

16,200/405,000=4% This is her commission rate.
