The kangaroo's speed in feet per second is 58.67 feet per second

<h3>What was the kangaroo's speed in feet per second?</h3>

The speed is given as:

Speed = 40 mph

Rewrite properly as

Speed = 40 miles per hour

1 mile = 5280 feet

So, we have

Speed = 40 * 5280 feet per hour

Evaluate

Speed = 211200 feet per hour

1 hour = 3600 seconds

So, we have:

Speed = 211200 feet per 3600 seconds

Evaluate the quotient

Speed = 58.67 feet per seconds

Hence, the kangaroo's speed in feet per second is 58.67 feet per seconds

An investor puts $2,500 into a life insurance policy that pays 8.5% simple annual interest. If no additional investment is made

Answer:

$2125 interest accumulated at the end of 10 years .

Step-by-step explanation:

Formula

$Simple\ inerest = \frac{Principle\times Rate\times Time}{100}$

As given

An investor puts $2,500 into a life insurance policy that pays 8.5% simple annual interest.

Principle = $2500

Rate = 8.5 %

Time = 10 years

Putting all the values in the formula

$Simple\ inerest = \frac{2500\times 8.5\times 10}{100}$

$Simple\ inerest = 25\times 8.5\times 10$

Simple interest = $ 2125

Therefore the $2125 interest accumulated at the end of 10 years .

Paula says that 2/3 is equivalent to 4/9 because 4 is a multiple of 2 and 9 is a multiple of 3. explain her error.

valentina_108 [34]

Answer:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

Step-by-step explanation:

Paula is wrong because, in order to be equivalent, the nominator and denominator of a fraction must have to be multiplied by the same number.

4/9 is basically obtained when we multiply the denominator of 2/3 by 2 and denominator by 3, which is wrong.

Thus, the correction is as follows:

Given the fraction

$\frac{2}{3}$

Multiply the nominator and denominator of the fraction by 2

$\frac{2\times 2}{3\times 2}=\frac{4}{6}$

Thus, the 4/6 is the correct equivalent expression of 2/3.
