Answer:

Step-by-step explanation:

You are being asked for the decimal equivalents of 0, 4/5, and 2 2/5.

You have correctly noted that the decimal equivalent of 0 is 0, or 0.0.

__

The decimal equivalents you want are apparently in hundredths. To find the fractional part, solve the proportion ...

  (your fraction) = x/100   ⇒   x = 100×(your fraction)

So, for the decimal equivalent of 4/5, you have ...

  x = 100(4/5) = 80

and the decimal is

 80/100 = 0.80 . . . decimal representing Marsha's shading

__

Similarly, the decimal equivalent of 2/5 is ...

  x = 100(2/5) = 40

  2 2/5 = 2 40/100 = 2.40 . . . decimal equivalent of Grace's shading

Answer:

answer is E

Step-by-step explanation:

4 x 12 i= 48

square root of 4=2

12= 4x3

square root of 4 again = 2

2x2 =4

so left with 4 square root 3

The equivalent expressions are (a) [tex]4\sqrt 3 = \sqrt{24} \cdot \sqrt{2}[/tex],  (d) [tex]4\sqrt 3 = \sqrt{12} \cdot \sqrt{4}[/tex] and (e) [tex]4\sqrt 3 = \sqrt{48}[/tex]

Equivalent expressions are expressions that have equal values

The expression is given as:

[tex]4\sqrt 3[/tex]

Express 4 as the square root of 16

[tex]4\sqrt 3 = \sqrt{16} \times \sqrt 3[/tex]

Combine the roots

[tex]4\sqrt 3 = \sqrt{16\times 3}[/tex]

[tex]4\sqrt 3 = \sqrt{48}[/tex]

Express 48 as the product of 12 and 4

[tex]4\sqrt 3 = \sqrt{12 \cdot 4}[/tex]

Split, into factors

[tex]4\sqrt 3 = \sqrt{12} \cdot \sqrt{4}[/tex]

Express 48 as the product of 24 and 2 in [tex]4\sqrt 3 = \sqrt{48}[/tex]

[tex]4\sqrt 3 = \sqrt{24 \cdot 2}[/tex]

Split

[tex]4\sqrt 3 = \sqrt{24} \cdot \sqrt{2}[/tex]

Hence, the equivalent expressions are (a), (d) and (e)

Answer:

1/192

Step-by-step explanation:

So, lets go over what we know:

There are 24 different sections on the circle.

3 of them are 500$.

1 of them are lose a turn.

Now, to find the answer, here is what we have to remember.

There are two different things you work with when solving this area of geometry.

"and" and "or"

When they say "or", you have two seperate chances, these chances need to be added together.

When they say "and", like in this question, you have two chances in the same thing. These chances need to be multiplyied together.

If this is a bit confusing, think of this another way:

When "or" = add one chance from the other.

In this case:

3/24 + 1/24=4/24.

However, "and" = multiply one chance by the other.

In this case:

3/24*1/24 = 3/576

This question is using "and". So our answer is:

3/576

This can be simplyfied as:

1/192

So this is our answer!

Hope this isnt to confusing and helps! :D

Answer:

r=s+5

Step-by-step explanation:

So, letsgo over what we know:

The regular price is r

The sale price is s

Now lets compare the difference between r and s:

10r = 5s

20r = 15s

30r = 25s

What is the difference between the r and s value in each situration?

Well, from what I can see, r is always 5 more than s.

This can be writen as:

r = s+5\

So this is our equation, for if you plug in any number for s, you will get an accurate r value.

For instance, if you say s is 25:

r=25+5

=

r=30

This looks just like the 30r=25s in the table above.

So:

r=s+5

Answer:

Hours slept = 6 hours

Hours awake = 18 hours

Step-by-step explanation:

Sasha got 1 hour of sleep for every 3 hours she was awake.

So,

This means:

Slept : Awake = 1 : 3

Total hours in a day = 24 hours

Let

Hours slept = 1x and hours awake = 3x

Hence,

1x + 3x = 24 hours

4x = 24

Divide both sides by 4

x = 24 / 4

x = 6

So,

Hours slept = 1(6) = 6 hours

Hours awake = 3(6) = 18 hours

What type of line the picture represent

Answer:

145

Step-by-step explanation:

So lets recall what a supplementary angle is. A suppelemenatry angle is  two angles that make up 180 degrees.(half circle)

This is different from a complenenary angle with is two angles that make up 90 degrees(quarter circle)

Ok, so we can write the equation for the supplementary angle as:

35+b=180

Lets subtract the angle we knwo from both sides:

b=145

Now we know that B(second angle) must be equal to 145 degrees.

Hope this helps!

Answer:

slope: 4

Y-intercept: -7

Step-by-step explanation:

you would have to solve for y so you subtract the 7 on both sides. then it is in slope-intercept form which is y=mx+b where m is slope and b is the y-intercept. the slope would be 4 and the y-intercept would be -7

Answer:

  +14, -3

Step-by-step explanation:

If x represents one of the numbers, then the equation can be written as ...

  x(11 -x) = -42

  x^2 -11x -42 = 0 . . . . quadratic equation whose solutions are the numbers

__

If we are to solve this by factoring, we look for factors of -42 that have a sum of 11 (the original problem). The factorization in integers can be any of ...

  -42 = 42(-1) = 21(-2) = 14(-3) = 7(-6)

The sums of these factor pairs are 41, 19, 11, 1. Clearly the numbers we're interested in are 14 and -3.

__

There are ways to solve quadratics that don't involve searching for integer factors by trial and error. A graphical solution is attached. The quadratic formula can also be used.

The solution to ax^2+bx+c = 0 is ...

  x = (-b±√(b^2-4ac))/(2a)

Then the solution to our quadratic is ...

  x = (-(-11)±√((-11)^2-4(1)(-42)))/(2(1)) = (11±√289)/2 = (11±17)/2

  x ∈ {-3, 14}

_____

Additional comment

When the solutions are integers, sometimes the easiest way to find them is to look for the factors of the product that have the correct sum. If the numbers are such that finding factor pairs is difficult or tedious, the more direct approach of graphing or using the quadratic formula may be preferred.
