How do you express 68,070,000,000,000 in Scientific Notation?

Answers

so since scientific notation is
(a number more than 1 and less than 10) times 10^x

move the decimal place to the left and count the places until the decimal is between the 6 and the 8
the number is 13
6.807 times 10^13 or
6.807e+13

6,807 times 10 to the power of 10

Brian invests £1300 into his bank account. He receives 10% per year simple interest.

How much will Brian have after 3 years?

Give your answer to the nearest penny where appropriate.

Answers

Answer:

£1690

Step-by-step explanation:

Amount invested by Brian = £1300

rate of simple interest = 10%

To find money Brian will have after three years

He will have amount invested in bank and interest earned in three years from that amount.

Simple interest for any principal amount p is given by

SI = P*R * T /100

where SI is simple interest earned

T is time period for which simple interest is earned

R is rate of interest

Substituting value of P , R and T we have

SI = 1300*10* 3 /100 = 390

Therefor interest earned will be £390

Total money with Brian after three years = principal amount invested + interest earned in 3 years

= £1300 + £390 = £1690

Mr Nersin likes to ride his bike. He rode for 1/2 hour. After a short rest, he rode 1/10 hour more. He traveled 4 miles in all. What is his average speed?

Answers

The distance traveled by Mr.Nersin = 4 miles
The time for which Mr.Nersin rode first = 1/2 hour
The time for which Mr.Nersin rode after a short rest = 1/10 hour
Then
The total time for which Mr.Nersin rode = (1/2) + (1/10) hour
= (5 + 1)/10 hour
= 6/10 hour
= 3/5 hour
So
Average speed of Mr. Nersin = Distance traveled / Time taken
= 4/(3/5) miles/hour
= (4 * 5)/3 miles/hour
= 20/3 miles/hour
= 6 2/3 miles/hour
= 6.67 miles per hour
So the average speed at which Mr.Nersin traveled is 6 2/3 or 6.67 miles per hour.

so first add them up
1/2+1/10
convert 1/2 with denomenator of 10
1/2 times 5/5=5/10
5/10+1/10=6/10=3/5
he traveled 3/5 hours
4 miles
4 miles per 3/5 hours
average speed is miles per 1 hour
4 miles =3/5 hours
multly both sides by 5/3 to meake 3/5 equal 1 (3/5 times 5/3=15/15=1)
20/3=1 hour
6 and 2/3=1 hour
6 and 2/3 miles per hour is speed

Convert 55 miles per
hour to feet per minute.

Answers

Answer:55 miles per hour= 4840 feet per minute
