Answer:

5/72

Step-by-step explanation:

dividing is equivalent to multiplying by the reciprocal

5/8×1/9

multiply the fraction

8×9=72

5×1=5

Answer: 5/72

Answer:

5/8 / 9 = 5/72

Step-by-step explanation:

5/8 / 9 = 5/72

Anytime you divide with a fraction remember this:

Same, change, flip:

You keep the first fraction, which is 5/8, the same.

Then you change the division sign to a multiplication sign.

After that, you flip the 9/1 (which is the same thing as 9) to 1/9.

So it would be 5/8 x 1/9.

If you multiply that, you can 5/72.

Therefore, 5/72 is your answer.

I hope this helped.

Answer:

After eight hours 6,561 people will know the rumor.

Step-by-step explanation:

Since each hour, every person who knows a rumor tells two other people, so that if one person starts the rumor, then after the first hour, three people know the rumor, and the next hour, those three people each tell two more people, to determine after eight hours, how many people will know the rumor, the following calculation must be performed:

Hour 0 = 1

Hour 1 = 1 + 2 = 3

Hour 2 = 3 + 2 x 3 = 9

Hour 3 = 9 + 2 x 9 = 27

Hour 4 = 27 + 2 x 27 = 81

Hour 5 = 81 + 2 x 81 = 243

Hour 6 = 243 + 2 x 243 = 729

Hour 7 = 729 + 2 x 729 = 2,187

Hour 8 = 2,187 + 2 x 2,187 = 6,561

Therefore, after eight hours 6,561 people will know the rumor.

Answer:

|8|a + |35|     or      = |-8|a+|-35_|

Step-by-step explanation:

8(a+5)=8•a+8•5

         =8a+35

         = |8|a + |35|     or      = |-8|a+|-35_|

Answer:

14 eggs

Step-by-step explanation:

150 grams need 6 eggs

1 gram need 6 ÷ 150 eggs

350 grams need 350×6÷ 150 =  14 eggs

Answer:

The volume is 210 cm³

Step-by-step explanation:

The way to solve volume is LxWxH, so you would do 6x5x7 and you get 210.

Answer:

mode = 2

Step-by-step explanation:

mode is the most frequently seen number.

median is the average so 5+4+2+2+2+2+1+1+3+2+2+3+3+2+1/15= 2 1/3

Answer:

Median is 2, Mode is 2

Step-by-step explanation:

1,1,1,2,2,2,2,2,2,2,3,3,3,4,5 to get the median you put the number from smallest to large then you x one out on each side until there is only one number left which would be 2

The mode is 2 because it is the most common number (aka it appears the most in the list)

Answer:

Option 4: y -x

Step-by-step explanation:

Option 1

Multiplying a positive and a negative number will result in a negative number.

For example, if x= -1 and y=5,

x(y)= -1(5)= -5 (a negative number)

Thus, option 1 is incorrect.

Option 2

In this option, we are essentially multiplying -1 to y, a positive number, before adding the result with x.

Since y is a positive number, -y is a negative number and hence x -y (when x is a negative number) will result in a negative number. Let's plug in values into x and y to check this.

For example, x= -2 and y=3.

x -y= -2 -3= -5

Option 2 is thus incorrect.

Option 3

Dividing a positive number with a negative number will result in a negative number.

For example: 6÷(-2)= -3

Option 3 is also incorrect.

Option 4

Subtracting a negative number from a positive number will result in a positive number.

For example: x= -1, y= 8

y -x= 8 -(-1)= 8 +1= 9

As seen from the example above, when the negative number is multiplied to negative 1, a positive sign results.

In summary, when a positive number is multiplied to a positive number, the resulting number is positive.

When a negative number is multiplied to a negative number, the resulting number is positive.

When a positive number is multiplied to a negative number, the resulting number is negative.

+(+)= +

-(-)= +

+(-)= -

This applies to division too.

Answer:

$80 interest will be owed for 4 months

Step-by-step explanation:

P is the principal amount, $4000.00.

r is the interest rate, 8% per year, or in decimal form, 8/100=0.08.

t is the time involved, 3....month(s) time periods.

Since your interest rate is "per year" and you gave your time interval in "month(s)" we need to convert your time interval into "year" as well.

Do this by dividing your time, 3- month(s), by 12, since there's 12 months in 1 year.

So, t is 0.25....year time periods.

To find the simple interest, we multiply 4000 × 0.08 × 0.25 to get that

Answer:

option (4)

Step-by-step explanation:

Calculate the length using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = A(2, 2) and (x₂, y₂ ) = B(- 6, 4)

AB = [tex]\sqrt{(-6-2)^2+(4-2)^2}[/tex]

      = [tex]\sqrt{(-8)^2+2^2}[/tex]

      = [tex]\sqrt{64+4}[/tex]

      = [tex]\sqrt{68}[/tex]

       ≈ 8.25 ( to 2 dec. places )
