Please help with question 6

Answer:

19 gram

Step-by-step explanation:

Formula of mass left after ionising: [tex]\frac{M}{2^{n} }[/tex]  where M is original mass and n is half lives.

Using the equation:

[tex]\frac{150}{2^{3} }[/tex] → 18.75

Therefore, 18.75 g left after ionising.

∵ If rounded to nearest gram then 19 gram.

a²+b²=c²√91²+√78²=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²c=√169

a²+b²=c²√91²+√78²=c²√8281+√6084=c²91+78=c²169=c²c=√169 =13

Answer:

$971

Step-by-step explanation:

To find the median value, place the numbers in value order (from lowest to highest) then find the middle:

So putting the weekly earnings for 2010 in value order:

501, 900, 971,  977, 1071

So the middle value is 971.  Therefore, the median = $971

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: 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

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

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:

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:

5/6

Step-by-step explanation:

Subtract 1/6 from 6/6:

Answer:

50 dollars.

Step-by-step explanation:

Jack has 5/9 of Jafar's money, meaning he has 125 dollars. To have the same amount of money as each other, Jafar needs to balance this out. If he gives jack 50 dollars, both of them will have 175 dollars. Hope this helps you out! Mind giving me brainliest? :)

The amount of money Jafar must give Jack so they would have the same amount of money is  $100.

The first step is to determine the amount that Jack has. In order to determine this amount, multiply 5/9 by $225.

5/9 x 225 = $125

Now, subtract $125 from $225

$225 - $125 = $100

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
