Gracie Shay wants to buy a new Hummer in five years. Gracie estimates the cost of the Hummer will be $28,000. If she invests $12,000 now at a rate of 6% compounded semiannually, she:

Answers

Answer:

Option 4 is correct

Step-by-step explanation:

The complete question is as follows:

Gracie Shay wants to buy a new Hummer in 5 years. Gracie estimates the cost of the Hummer will be $28,000. If she invests $12,000 now, at a rate of 6 percent compounded semiannually, she:

1.Will have enough money

2.Will have exactly $16,000

3.Will have $18,000

4.Will have $16,126.80

5.None of these

Solution:-

- The plan is to buy a new Hummer that costs C = $28,000 in t = 5 years.

- She invests P = $12,000 now at an interest rate i = 6% compounded semi-annually.

- We will calculate the amount of money, (compound interest formula), that Gracie has at the end of 5 years:

A = P*( 1 + i )^n

- Where, A : Amount after n periods.

n : Compounding period in years.

- The compounding period (n) is denoted as the number of time the interest in compounded over the time period t. Since the interest is compounded semi-annually then the compounding period would be:

n = t* ( 2 periods / year )

n = 5*2 = 10 periods.

- Now use the above "compounded interest" formula for i to be distributed for the whole year i.e half of 6%:

A = (12,000)*( 1 + 6/200)^10

A = 12,000*(1.03)^10

A = $16126.99

Here is the solution of the given problem above.
Given that the estimated cost of the Hummer is $28,000, and that she invests $12,000 with a 6% rate compounded semiannually. Semiannually, that would be twice a year, so it is the rate every 6 months. Let's get the 6% of $12,000 and it would be $720. Therefore, she will pay a total of $13,440 in a year. Hope this answer helps.

In which of the following units is acceleration expressed? A. Kilograms
B. Meters per second squared
C. Foot-pounds
D. Newtons

Answers

The question is,' in which of the following unit is acceleration expressed. The correct option is B. Acceleration is defined as the rate of change of velocity per unit time. The unit of velocity is meter per second while the unit of time is second, therefore, the unit of acceleration is meter per second per second or meter per second squared [m/s2].

your answer is B. Meters per second squared

The table below shows the ticket rates for whale watching trips offered by Orca Magic Tours: Age Ticket Price Under 3 years free 3 to 12 years $32 Over 12 years $44 On a certain day, the company took 82 people on whale watching trips. There were 54 children aged 12 and under, of which some children were under 3 years. If x represents the number of children under three years, which equation can be used to find the value of x, where C represents the total amount of money collected from tickets that day? (54 + x)32 + (82 − A: (54 + x)) ⋅ 44 = C

B: (54 − x)32 + (82 − 54) ⋅ 44 = C

C: (82 + x)32 + (82 − (54 + x)) ⋅ 44 = C

D: (82 − x)32 + (82 − 54) ⋅ 44 = C

@Taskmasters @Kamariasutton @Zainabdalrazzaq ShootingStar28

Answers

Their are 82 people. 54 are 12 and under. The rest are adults ($44 dollars each)

Cost of all people = (12 and under's cost) + (adults cost)

Adults cost = (82 - 54) * 44

Cost of children 3 - 12 = (54 - # of children under 3 or x) * 32

Cost = (54 - x) * 32 + (82 - 54) * 44

The answer is C.

There are 25 students in Mrs. Venetozzi’s class at the beginning of the school year, and the average number of siblings for each student is 3. A new student with 8 siblings joins the class in November. What is the new class average for number of siblings? Round your answer to the nearest hundredth.

Answers

It is 25/3 which gives you 8.3 but let's say it is 8. So 8 students have 3 siblings and 9 have 2-0 siblings and 8 have 4-any number higher siblings. So if that kid joins there would be an avg of 3.63 siblings so 3.63 is the answer.
