Answer:

Each sample has a volume of 0.70 L.

Step-by-step explanation:

Let

  • v = volume of ocean water = 70 litres
  • s = number of samples = 100 samples

To find the volume of ocean water in each sample we have to perform the following division.

v/s = 70 L/100 sample = 0.70 L/sample

Each sample has a volume of 0.70 L.

Which of the following lists is in order from smallest to largest?
Stells [14]

Answer:

The following list is in order from smallest to largest is 17\%,0.175,\frac{2}{11},\frac{1}{5}

Step-by-step explanation:

Let the numbers be \frac{2}{11},\frac{1}{5},17\%,0.175

To find the list in order from smallest to largest:

\frac{2}{11},\frac{1}{5},17\%,0.175

Rewritting the above numbers as below

0.18,0.5,\frac{17}{100},0.175

0.18,0.5,0.17,0.175

Now arranging the numbers in order from smallest to largest

0.17,0.175,0.18,0.5

\frac{17}{100},0.175,\frac{2}{11},\frac{1}{5}

The arranged numbers can be written as

17\%,0.175,\frac{2}{11},\frac{1}{5}

The following list is the order from smallest to largest is 17\%,0.175,\frac{2}{11},\frac{1}{5}

An actor invests some money at 7%, and $24000 more than four times the amount at 8%. The total annual interest earned from the i
natita [175]

Answer:

  • $70,000 at 7%
  • $304,000 at 8%

Step-by-step explanation:

<u>Given</u>:

  Total interest earned on two investments is $29,220.

  An amount is invested at 7%.

  $24,000 more than 4 times that amount is invested at 8%.

<u>Find</u>:

  The amount invested at each rate.

<u>Solution</u>:

  Our strategy will be to define a variable representing the amount invested at 7%, use that variable to write an expression for the amount invested at 8%, then write an equation for the total return on the investments.

Let x represent the amount invested at 7%. Then (24,000+4x) will be the amount invested at 8%. The total interest earned will be ...

  interest on 7% account + interest on 8% account = total interest

  0.07x + 0.08(24000+4x) = 29220

  0.39x + 1920 = 29220 . . . . . . . . . . . simplify

  0.39x = 27300 . . . . . . . . . . . . . . . . . .subtract 1920

  x = 27300/0.39 = 70000 . . . . . . . . . divide by the coefficient of x

  24,000 +4x = 24,000 +280,000 = 304,000 . . . . amount invested at 8%

He invested $70,000 at 7% and $304,000 at 8%.

<u><em>Check</em></u>

The answer must satisfy ...

  7% interest + 8% interest = 29,220

  0.07×70,000 +0.08×304,000 = 4,900 +24,320 = 29,220 . . . . as required
