Is it 0.2 repeating? I'm not sure sorry hon...

No, this is the definition of the cosine.

The sine in a right triangle is the OPPOSITE side divided by the hypotenuse

This is cross multiplying, so basically you're multiplying in a big X. So, 

multiply (1/2) by 4, to get 2, and then multiply 3 by x, to get 3x.

You now have 2 = 3x, and we need to isolate the variable. To do that, we use the opposite operation the "x" is involved in. Here we have 3x (the x is multiplied to the 3) so we will divide 3x by 3. This cancels out the 3, leaving just "x".

What you do to one side of the = sign, you must do to the other, so we will also divde 2 by 3. This will give you 2/3 = x or, 0.67 = x (whichever form your answer must be in).

I know it can be confusing, so I including a picture working it out to help. Good luck! 

16r^2 + 18r + 5

(2r + 1) (8r + 5)

Well if the number is 100 dollars and it increases by four hundred percent it now costs 400 dollars. But if it was 100 dollars after the increase the original price was 25 dollars.

The ratio for this table is 16 ounces: 1 pound. So that means if there are 4 pounds you multiply it my 16 considering there are 16 ounces in 1 pound. Yes, this sounds confusing but it is quite simple once you get the hang of it. So your answers are:
64
40
28
96

The rancher can conclude that his sheep are not proportionately spread out across the 40 acre pasture.

T²+ 2t + 1 = 0

a=1, b=2 & c=1 The formula is x'=[-b+√(b²-4ac)]/(2a)

and====================>x"=[-b-√(b²-4ac)]/(2a)

x' = [-2+√(2²-4(1)] / 2(1) ===> x' = -2/2 ==> x' =-1 & x" = -1
x'=x"= -1

Y= 2/3x-2

-3y= -2x+6
Divide by -3

Answer:

3/42=1/14

Step-by-step explanation:

odd numbers: 3/7 even numbers: 1/6

3/7 x 1/6= 3/42 divided by 3= 1/14

The radius of that circle would be 5

The diameter is two times the radius, and 2 times 5 equals 10, which is the same as 10 divided by 2 being equal to 5.

To find the answer, divide the 6 cookies by the 9 people, and convert that into a fraction and that will give you the answer you need!

If one raw contains 3x-2 trees & if the total trees in the rectangle are 24x-16, that means Horizontal Rows x Vertical Rows =Total number of trees:

(3x-2) * Vertical Rows = 24x-16 ===> Vertical Rows =(24x-16) / (3x-2)

Perform the division & you will find Vertical Rows =8

It would be 5p

5x7 = 35

Circumference= 2*pi*radius
