5/9 to a decimal would be .5 repeated

The answer is .5 repeated

Do not put your answer as .5 because .5 is 5/10

A proper answer can be something like "0.5 repeated, 0.5555..., or .5 with a line over the 5"

Answer:

  (a) 1. Distributive property 2. Combine like terms 3. Addition property of equality 4. Division property of equality

Step-by-step explanation:

Replacement of -1/2(8x +2) by -4x -1 is use of the distributive property, eliminating choices B and D.

In step 3, addition of 1 to both sides of the equation is use of the addition property of equality, eliminating choice C. This leaves only choice A.

_____

Additional comment

This problem makes a distinction between the addition property of equality and the subtraction property of equality. They are essentially the same property, since addition of +1 is the same as subtraction of -1. The result shown in Step 3 could be from addition of +1 to both sides of the equation, or it could be from subtraction of -1 from both sides of the equation.

In general, you want to add the opposite of the number you don't want. Here, that number is -1, so we add +1. Of course, adding an opposite is the same as subtracting.

In short, you can argue both choices A and C have correct justifications. The only reason to prefer choice A is that we usually think of adding positive numbers as addition, and adding negative numbers as subtraction.

Answer:

x = 40.3

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

sin theta = opp / hyp

sin x = 11/17

Taking the inverse sin of each side

sin ^-1 ( sin x) = sin ^-1( 11/17)

x = 40.32

Rounding to the nearest tenth

x = 40.3

Answer:

x = 6+b

Step-by-step explanation:

-6 = -x+b

Subtract b from each side

-6-b = -x+b-b

-6-b = -x

Multiply each side by -1

6+b = x

=========================================================

Explanation:

Think of unwrapping a present and doing so without any unnecessary tearing. That means there aren't any little small pieces thrown away. There are many ways to unwrap a 3D box, and this diagram shows one of many ways. This flat layout is the 2D version of the 3D surfaces.

To find the surface area of the 3D figure, we simply need to find the area of each rectangle in this 2D flat net. Once we know all the little areas, we add them up to get the surface area.

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

The lowest rectangle is 3 cm by 5 cm, so its area is 3*5 = 15 cm^2. Let A = 15 so we can use it later.

Let's move to the middle row of four rectangles. From left to right, we have these four rectangular areas

I'll call these results B,C,D,E in the order given above. So B = 21, C = 35, etc.

The rectangle up top has area of 3*5 = 15 cm^2. I'll let F = 15

Lastly, we'll add up the sub-areas to get the grand total

A+B+C+D+E+F = 15+21+35+21+35+15 = 142 cm^2 is the surface area

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

Another pathway to the answer:

If you can picture how this flat diagram would fold up, then you would see that we'd get a 3D block with the following dimensions

The order of L,W,H doesn't really matter.

Then we can use the 3D block surface area formula like so

SA = 2*(LW + LH + WH)

SA = 2*(7*5 + 7*3 + 5*3)

SA = 2*(35 + 21 + 15)

SA = 2*71

SA = 142 cm^2 is the surface area

As you can see from the third step, we have "35", "21" and "15" show up again. The 2 out front is because we have 2 copies of each item mentioned.

Answer:

B Y=1

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

What is the greatest value that sin(x) + 1 can have? It isn't 1.

f(90) = sin(90) + 1

f(90) = 1 + 1 = 2

What is the smallest value that sin(x) + 1 can have? It still isn't one.

f(-90) = sin(-90) + 1

f(-90) = -1 + 1 = 0

So the midline is (2 + 0)/2 = 1

y = 1 is the answer.

Answer:

hard quiz

Step-by-step explanation:

The value of the expression | m^2+n^2 | at m = -5 and n = 3 is 34.

Given,

| m^2+n^2 |

We need to find the value of this expression at m = -5 and n = 3.

The modulus of x is given as |x|.

The modulus of a negative x is also positive.

|-x| = x

Example:

x + 2  at x = 1

= 1 + 2

= 3

Find the value of | m^2+n^2 | at m = -5 and n = 3.

| m^2+n^2 |

= | (-5)² + (3)² |

= | 25 + 9 |

= | 34 |

= 34

Thus the value of the expression | m^2+n^2 | at m = -5 and n = 3 is 34.

Answer:

y = x + 2

Step-by-step explanation:

The slope of the given points (6, 8) and (2, 4) is m = 1.

The y-intercept found through the slope, m = 1, is b = 2.

So, m = 1 and b = 2, right?

Let's put this together into the formula y = mx + b, we'll get: y = x + 2

Step-by-step explanation:

hope it can work for you mark me as brain liest

Since the problem stated the weight and price are in a linear relationship, we can use y=mx+b.

First, let's calculate our slope.

m = (4950-3700)/(0.75-0.5) = 5000

Now, let's solve for b.

3700 = 5000(0.5) + b

Simplify the right side of the equation.

3700 = 2500 + b

Subtract 2500 from both sides

1200 = b

Now our equation looks like this:

y  = 5000x + 1200

Let's plug 2.5 in for x to solve for the diamond cost.

y = 5000(2.5) + 1200

Simplify the right side.

y = 13700

The average price of a 2.5 carat diamond is $13700

Answer:

20 x 6

Step-by-step explanation:

23 x 6 = 138

We already have 3 x 6 on the right side, however, so subtract 3 x 6 or 18 from 138:

138 - 18 = 120

Now we have to fill in the blank with an answer that, when multiplied, equals 120 so that the equality is true.

The only option that works out to 120 is the second option, 20 x 6.

Answer:

(20×6)

Step-by-step explanation:

23×6=(20×6)+(3×6)

138=120+18

138=138

Answer:

y=3, 0; 9x-3y=18, 3; line through (5, 7) and (5, – 8), undefined; the line through ( – 4, – 1) and (-1,–7), -2;

Step-by-step explanation:

y=3 is a horizontal line so the slope is 0

9x-3y=18 can be written as 3y=9x-18 or y=3x-6 so the slope is 3

the line through (5,7) and (5,-8) is a vertical line since the x value didnt change between the two points so the slope is undefined

we have to find the slope of the line through ( – 4, – 1) and (-1,–7). to do this use the formula (y_2-y_1)/(x_2-x_1)=(-7-(-1))/(-1-(-4))=(-7+1)/(-1+4)=-6/3=-2 so the slope is -2
