Show how to solve 378*6 using place value with regrouping. Explain how you knew when to regroup.

Answers

To regroup 378 x 6, you must first establish the place values of each digit. 3 has a place value of 300, because it is in the hundreds column; 7 has a place value of 70 because it is in the tens column; 8 has a place value of 8 because it is in the units column. This means you can regroup 378 x 6 as (300 x 6) + (70 x 6) + (8 x 6). This makes 2,268.

Jade invested $13,500 at 5.2% interest, compounded semiannually, and she wants to know how much her investment will be worth in 8 years
Part 1: What is the periodic interest rate of jade investment
Part 2:  How many compounding periods does jades investment offer in a year? how about in 8 years?

Answers

Part 1: What is the periodic interest rate of jade investment?

Each compounding period is done semi-annually, which means twice a year. Since the given interest rate is annual, then 5.2% divided by half should yield the period interest rate, which is 2.6%

Part 2: How many compounding periods does Jade's investment offer in a year? how about in 8 years?

In 1 year, there are 2 compounding periods. In 2 years, there are 16 compounding periods.

Answer:

Part 3: What expression can Jade write to figure out how much her investment will be worth in 8 years?   F = $13,500.00 * (1 + .052/2) ^ (2*8)

Part 4: How much will Jade's investment be worth in 8 years?  $20,355.96

Step-by-step explanation:

Time = 8 yearsInterest rate = 14%
Principal = $1,010

Step-by-step explanation:

Brooke and Lamont ran a half marathon. Brooke finished in 1 hour 40minutes. Lamont finished in 95 minutes. Who had the faster time?
A. Brooke finished in 140 minutes, so Lamont was faster.
B. Brooke finished in 100 minutes, so Lamont was faster.
C. They had the same time, so they tied.
D. Brooke finished in 90 minutes, so she was faster.

Answers

Answer:

B. Brook finished in 100 minutes, so Lamont was faster.

Step-by-step explanation:

1 hour = 60 Minutes

60 minutes + 40 minutes = 100 Minutes.

If you run and you have more minutes then someone else that means you ran for a longer time and your a little bit slower?
