Alicia Bitman, age 30, plans to purchase a $200,000, 5-year term life insurance policy. What is the annual premium?

zhenek [66]

Answer: $770

Step-by-step explanation:

Number of units to be purchased by Alicia:

= 200,000 / 1,000

= 200 units

Alicia is purchasing a 5-year term life insurance policy. At age 30, the cost per $1,000 unit of insurance is $3.85 for a female.

The formula for the annual premium is:

= Number of units purchased * Premium per $1,000

= 200 * 3.85

= $770

ratelena [41]

Answer:

32+q

Step-by-step explanation:

<u><em>The complete question is</em></u>

Jake has 32 quarters on his desk, molly has q quarters in her purse.

Which algebraic expression represents the total number of quarters that Jake and Molly have?

we know that

To find out the total number of quarters that Jake and Molly have, sum the amount of quarters that Jake has plus the amount of quarters that Molly has

Let

x ----> the amount of quarters that Jake has

y ----> he amount of quarters that Molly has

so

x+y

we have

$x=32\ quarters\\y=q\ quarters$

substitute

32+q

Can someone help me out with this question?

3x/4 - x/3

To simplify this, we need to first find a common denominator, or the Greatest Common Factor (GCF) of the two denominators (4 and 3). The GCF of 3 and 4 is 12.

Now, we have to multiply the numerator AND denominator of each individual term by the same factor such that the denominator equals 12.

So for the first term, 3x/4, we know that 12/4 = 3, therefore we need to multiply the fraction by 3/3, which is equivalent to 1.

3x/4 * 3/3 = 9x/12

Now, let's do the same for the other term x/3. We know that 12/3 = 4, therefore we need to multiply the fraction by 4/4, which is equivalent to 1.

x/3 * 4/4 = 4x/12

Now, lets substitute these equivalent fractions back into the original expression.

3x/4 - x/3 = 9x/12 - 4x/12 = 5x/12

Thus, your answer is #4, or 5x/12

Calculate the density of a block of 400g and volume 0.02m3

Dima020 [189]

The density of the block will be 20000 g/m³

<em><u>Explanation</u></em>

Given that, mass $(m)$ of the block is 400 g and Volume $(V)$ is 0.02 m³

<u>Formula for Density is</u>: $D= \frac{m}{V}$

So, plugging the values of $m=400$ and $V=0.02$ into the above formula, we will get.....

$D=\frac{400}{0.02}g/m^3\\ \\ D= 20000 g/m^3$

So, the density of the block will be 20000 g/m³
