A stack of boards is 24 inches high. each board is 3/4 of and inch thick. How many boards are in the stack?

Answer:

15 oz.

Step-by-step explanation:

Rounding to the nearest ounce:

14.853

Rounding notes:

If the number one place to the right of the rounding number is greater than 5, the number increases by 1.

If the number one place to the right of the rounding number is less than 5, the number stays the same and anything to the right of the rounding number changes to 0.

Work:

4 represents the 'ounces' place value.

To identify the rounding of 4, we need to determine if the value 8 is greater than 5, or less than 5.

8 > 5, meaning 4 increases to 5.

New rounded number = 15 oz.

Answer:

v = 10

Step-by-step explanation:

Isolate the variable by subtracting both sides by 11

v/2 = 5

multiply both sides by 2 to get rid of the fractions and to get the variable by itself

v = 10

Check

(10)/2 + 11 =16

5 + 11 = 16

16 = 16

Answer:

$14.88

Step-by-step explanation:

Ria earns 1.2 times more than Peter does

Peter earns $12.40

To solve, you have to multiply the amount peter has by 1.2

12.40(1.2) = 14.88

Therefore, Ria earns $14.88

Answer:

We can round off 198.5565097 cm as 199cm

Step-by-step explanation:

The appropriate degree of accuracy of the area of the circle she got is approximately a whole number which is; 199 cm²

We are told that;

Diameter = 15.9 cm

Area = 198.5565097 cm²

Now, we are told that was the are she got from the calculator. That is calculator value and as such for accurate approximation we have to approximate to the nearest whole number.

198.5565097 cm² ≈ 199 cm²

Answer:

5.  [tex]\frac{2}{8}[/tex]

6. [tex]\frac{10}{12}[/tex]

7. [tex]\frac{11}{20}[/tex]

Step-by-step explanation:

5.  [tex]\frac{1}{2} - (\frac{1}{8} +\frac{1}{8} )\\[/tex] = [tex]\frac{2}{8}[/tex]

Step 1: Solve for the fractions in the parentheses.

[tex]\frac{1}{8} +\frac{1}{8}[/tex]

This will be easy because they both have the same denominator.

= [tex]\frac{2}{8}[/tex]

Now we have:

[tex]\frac{1}{2} -\frac{2}{8}[/tex] =

Find the common denominator and change the numerator accordingly:

[tex]\frac{4}{8} -\frac{2}{8} = \frac{2}{8}[/tex]

6. [tex]\frac{3}{4} +(\frac{1}{4} -\frac{1}{6} )[/tex]

Step 1: Solve for the fractions inside the parentheses

Find the Common Denominator of both and change the numerators accordingly

[tex]\frac{1}{4} -\frac{1}{6} = \frac{3}{12} -\frac{2}{12}[/tex]

Then just subtract them

[tex]\frac{1}{12}[/tex]

Now we have:

[tex]\frac{3}{4} +\frac{1}{12}[/tex]

Find the common denominator:

[tex]\frac{9}{12} + \frac{1}{12}[/tex]

Then just add them

[tex]\frac{10}{12}[/tex]

7. [tex](\frac{1}{2} +\frac{3}{20} )-\frac{2}{20}[/tex]

Step 1: Solve the fractions in the parentheses

[tex]\frac{1}{2} +\frac{3}{20} =\frac{10}{20} +\frac{3}{20}[/tex]

Then solve

[tex]\frac{10}{20} +\frac{3}{20} =\frac{13}{20}[/tex]

Now we have

[tex]\frac{13}{20} -\frac{2}{20}[/tex]

Subtract

= [tex]\frac{11}{20}[/tex]

Answer:

Answer:

There are integers that are not rational numbers is false

There are whole numbers that are not rational numbers is false

There are integers that are not whole numbers is true

All rational numbers are integers is false

Step-by-step explanation:

Integers are whole numbers, or numbers that aren't fractions. For example, 1 and 2 are integers, while 5/2 isn't. Integers will always be rational, as rational means that it can be represented as a fraction and the integer 2 can be represented as 2/1 as can 4/2.

Whole numbers are just positive integers.

Not all integers are whole numbers though, since negative integers would not fit the definition of whole numbers (whole numbers have to be positive)

All rational numbers are integers is false, as rational numbers include fractions such as -3/7 or 2/5, which don't cover integers.

Answer:

4 root 5

Step-by-step explanation:

assume / to be root sign

/10 x /8

simply both roots so that one of numbers is a square number

/10= /2 x /5

/8= /2 x /4

so

/4=2 and /2 x /2= 2

2×2=4 and you have /5 left over so

4/5

Answer:

[tex]\sqrt{11}[/tex]

Step-by-step explanation:

well first you have to plug in a and c in the Pythagorean theorem.

[tex]a^2+b^2=c^2\\(2\sqrt{2})^2+b^2 =(\sqrt{15})^2[/tex]

then squaring the square roots cancels them out sooo it becomes

[tex]4 +b^2=15[/tex]

and then isolate b

[tex]b^2 = -4 +15\\\\\\b=\sqrt{-4+15} \\b=\sqrt{11}[/tex]

and there you have it. b is [tex]\sqrt{11}[/tex]

Answer: 2/4 or 1/2

Step-by-step explanation: The amount of bananas to the amount of fruits in general i 2/4 or 1/2 because the person with the fruits has 4 fruits in general, so 2 out of 4 is 2/4 or just 1/2.

Answer:

1/2

Step-by-step explanation:

4 fruit and 2 of them are banana so 2/4

banana goes on top and the total number of fruit go on the bottom

to simplify divide numerator and denominator by 2

2/2          1

------ = ---------

4/2          2        

Hope this helps you!!! :D
