Answer:

1/2, 4/8, 2/2, 4/3, 3/2

Step-by-step explanation:

If you put the fractions into decimals it would easier to see which ones are greater and leasts.

4/3 = 1.333...

1/2 = 0.5

4/8 = 2/4 = 1/2 = 0.5

3/2 = 1.5

2/2 = 1

Am not sure if 1/2 go first or 4/8.

Answer:

y= 5/3 which is 1 2/3

Step-by-step explanation:

trust me

y=5/3

Answer:

1/2 is 0.5 so -1/2=-0.5

-0.5 is greater than -1

use a number line

Step-by-step explanation:

By looking at the number line we can easily tell which integers are greater (larger) than a certain number and which are less (smaller) than the number. When two numbers are located on a number line, the number to the right is larger than the number to the left. –1 is less than –1/2 because it is to the left of –1/2.

Answer: 0.067 litres of water

Step-by-step explanation:

The mode is:

Concentration of new solution = Moles of acid in original solution / (Volume of original solution + Volume of water added)

Assume volume of water added is w.

12 = 16 (0.2) / (0.2 + w)

(0.2 + w) * 12 = 3.2

0.2 + w = 3.2 / 12

w = (3.2 / 12) - 0.2

w = 0.067 litres of water

The amount of water you should add to the solution is 0.067 liters.

Given

You have 0.2 liters of an acid solution whose acid concentration is 16 moles per liter.

You want to dilute the solution with water so that its acid concentration is only 12 moles per liter.

You can also use the solution dilution calculator in order to calculate the concentration of ions in a diluted solution.

The amount of water you should add to the solution is given;

[tex]\rm Concentration \ of \ new \ solution =\dfrac{\text{Moles of acid in original solution } }{\text{Volume of original solution + Volume of water added}}\\\\12=\dfrac{16(0.2)}{0.2+w}\\\\12 (0.2+w)=16(0.2)\\\\2.4 +12w=3.2\\\\12w=3.2-2.4\\\\12w=0.8\\\\w=\dfrac{0.8}{12}\\\\w=0.067[/tex]

Hence, the amount of water you should add to the solution is 0.067 liters.

Answer:

x<110

Step-by-step explanation:

-x/10>-11

-x>-11*10

-x>-110

x>110

x<110

Answer:

x > - 110

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the greater than a sign from both sides of the inequality :

       x / 10 - ( -11 ) > 0

                  x

Simplify   ——

                 10

   x    

 —— -  -11  > 0

  10

Subtracting a whole from a fraction

Rewrite the whole as a fraction using  10  as the denominator :

              -11                -11 • 10

   -11 =  ———  =  ————————

               1                     10  

Equivalent fraction: The fraction thus generated looks different but has the same value as the whole

Common denominator: The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

  x - (-11 • 10)               x + 110

———————  =  ———————

      10                            10

       x + 110

 ———————  > 0

          10

Multiply both sides by  10

Subtract  110  from both sides

           x > -110

Inequality plot for

0.100 x  + 11.000  >  0

x > -110

Write the problem as an equation:

5n <65

Solve for n by dividing both sides by 5:

n <13

Because the inequality does not contain an equal sign, n (13) is not included in the answer so there would be an open circle on the number 13

The correct answer would be A.

Answer:

  m = 1/2

  b = -7

Step-by-step explanation:

The formulas for these can be used.

  m = (y2 -y1)/(x2 -x1) . . . . . . . . . formula for slope given 2 points

  m = (-9 -(-11))/(-4-(-8)) = 2/4

  m = 1/2

__

  b = y1 -m·x1 . . . . . . . . . . . . formula for y-intercept given slope and point

  b = -11 -(1/2)(-8) = -11 +4

  b = -7

Answer:

C

Step-by-step explanation:

Remark

There are probably a couple of ways that you could do this. I'm going to pick the most obvious way.

Givens.

KN = 2.5

NO = 10

LM = 3

MP = x

Equation

NO/KN = PM / LM

Solution

10 / 2.5 = x / 3              Cross multiply

2.5x = 10 * 3                 Combine

2.5x = 30                      Divide by 2.5

x = 30/2.5

x = 12

That looks like it should be the answer, and it almost is, but you are asked for LP.

LP = LM + MP

LP = 3 + 12

LP = 15

The answer is 15
