James is looking into life insurance. He currently makes $50,000 a year and has two children, ages 15 and 11. How much coverage and how long a term of life insurance would you recommend to James?

Answers

  • The coverage amount is $500,000
  • The recommended term of life insurance is 10-year term.

Based on the information given i would recommend insurance coverage amount of $500,000 and a term of life policy of 10-year term.

James will need a coverage amount of $500,000 until the two children are financial independent and can cater for themselves.

Using a long term policy of 10 years term of life insurance is recommended as the older will be 25 years and the youngest will be 21 years by then.

Coverage insurance amount:

Insurance coverage=Salary× Term of life

Insurance coverage=$50,000×10 year

Insurance coverage=$500,000

Inconclusion:

  • The coverage amount is $500,000
  • The recommended term of life insurance is 10-year term.

Step-by-step explanation:

If James wants to cover both of his children at his current salary until they both can support themselves on their own, he would need a 10-year term policy (if the youngest moves out when he/she is 21) with a face value of $500,000 (current salary-$50,000*10 years).

Line SU bisects angle RST. Which statement is NOT true?A) ∠RST = ∠RSU
B) ∠RSU = ∠UST
C) ∠SQU = ∠SPU
D) PS = QS

Answers

In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle.
so the answer is B

Answer : The incorrect option is, (A) ∠RST = ∠RSU

Step-by-step explanation :

As we are given that, line SU bisects angle RST and SPUQ is a rhombus.

First we have to determine that ΔSQU and ΔSPU are congruent triangles.

Proof:

Side SU = Side SU (common side)

∠SQU = ∠SPU (In rhombus opposite angle are always equal)

∠RSU = ∠UST (angle bisector)

ΔSQU ≅ ΔSPU (By ASA congruency)

So, Side PS = Side QS

∠RST = ∠RSU this option is wrong because \angle RSU=(1)/(2)\angle RST

Thus, the incorrect option is, (A) ∠RST = ∠RSU

The number that rode in columns was 3 2/3 times the number that rode in rows. If 2200 rode in columns, how many rode in rows?

Answers

Answer:

600

Step-by-step explanation:

Given parameters:

    Number that rode in columns = 3(2)/(3) times the number that rode in rows.

       2200 rode in columns

Unknown:

Number of people that rode in rows = ?

Solution:

  Let the number of people that rode in columns  = C

   Let the number of people that rode in rows  = R

                 C = (11)/(3)R

Number of people that rode in rows  = 2200;

            2200 =  (11)/(3)R

             11R  = 2200 x 3

                R  = (2200 x 3)/(11)

                R = 200 x 3

               R  = 600

Number of people that rode in rows  = 600

A survey found that 3 out of 100 people have red hair.On the basis of this survey, how many people in a group of 12,000 people are likely to have red hair?

A.4000

B.360

C.36

D.3

Answers

B is the answer because you cross multiple the two fractions.
(3)/(100) (x)/(12000)
3 *12,000=36,000
36,000/100=360

Answer:

THE ANSWER IS 360

please deal with it lol :)

good luck on the test

Julie drives 100 mi to Grandmother's house. On the way to Grandmother's, Julie drives half the distance at 33.0 and half the distance at 80.0 . On her return trip, she drives half the time at 33.0 and half the time at 80.0 . What is Julie's average speed on the way to Grandmother's house? What is her average speed on the return trip?

Answers

Average speed is ALWAYS calculated as total distance / total time 
total distance is 100mi 
total time is (50mi / 33) + (50mi / 80) 
total time is = 1.52 + 0.625 = 2.145 
so average speed going to grandmothers house is 100mi / 2.145 hrs = 46.62 mph 

on her return trip 
x = V1 x t/2 + V2x t/2 
100 = 33t/2 + 80t/2 
100 = 113t/2 
t = 100x2/113 = 1.7699hrs 
average speed = 100mi/1.7699hrs = 56.60mph
