Answers

Answer 1
Answer:

Given the average speed of Serena during her trainingand the time elapsed, the total distance that she ran is 16km.

Option D) 16km is the correct answer.

What is speed?

Speed is simply referred to as distance traveled per unit of time.

It is expressed as;

Speed = distance ÷ time

Hence,

Distance = Speed × time; d = r × t

Given the data in the question;

  • Speed or rate r = 8km/hr
  • Time elasped t = 2hr
  • Distance travelled d = ?

From the given formula;

d = r × t

We substitute our given values into the expression above.

d = 8km/hr × 2hr

d = 16km

Given the average speed of Serena during her trainingand the time elapsed, the total distance that she ran is 16km.

Option D) 16km is the correct answer.

During unusually cold weather, the temperature in Miami beach was 10'C. This was 12 degrees more than in Tallahassee. What is the temperature Tallahassee

Answers

Answer:

-2°

Step-by-step explanation:

We have that the temperature in Miami beach was 10° C.

Also, this temperature is 12° more than the temperature in Tallahassee.

So, we get that,

Temperature in Miami = 12°  + Temperature in Tallahassee

i.e. Temperature in Tallahassee = Temperature in Miami - 12°

i.e. Temperature in Tallahassee = 10° - 12°

i.e. Temperature in Tallahassee = -2°

Hence, the temperature in Tallahassee is -2°.
The answer is -2'C !! ^_^

Megan took a cab ride and was charged a fare of $1.50 per mile and an additional charge of $5 for her luggage. If Megan traveled x miles, which expression gives her total fare?

Answers

For example let's say Megan has to pay the cab driver $50. Here's the equation 50=1.50x + 5First you want to get x by itself on one side. So subtract 5 on both sides50=1.50x + 5-5 -5---------------------------45=1.50xNow that you have x on one side; however, you want to divide to get the answer.45=1.50x-----------------------1.50x = 30So if Megan pay $50 that mean she rode 30 miles~by the way I'm sorry if you are looking at the answers and it isn't in the right place, I'm answering this on a tablet~

Brian wants to buy a motorcycle and is planning to get motorcycle insurance. Suppose the average accident rate is 0.1, and the average expenses incurred on accidents is $38,000. The insurance plan has a yearly premium of $1,000 and a deductible of $4,000.If after 4 years of insuring 100 people, 9 motorcycle drivers had an accident, where does the company stand after money has been taken in and paid out for this group of 100 insured people?

$85,500
-$36,000
$94,000
$58,000

Answers

Answer:

The correct option is $94,000

Step-by-step explanation:

Yearly premium under the insurance plan = $1,000

Total premium from single motorcycle driver in 4 years = $1,000 * 4 = $4,000

Number of people insured = 100

Total premium collected from 100 motorcycle drivers = $4,000 * 100 = $400,000

Average expenses incurred on accident = $38,000

Deductible = $4,000

Net expenses incurred per accident = $38,000 - $4,000 = $34,000

In 4 years , 9 motorcycle drivers had an accident

Total expenses incurred for accident = $34,000 * 9 = $306,000

Net savings of Insurance Company = total premium - total expenses = $400,000 - $306,000 = $94,000

Hope it helps.

Thank you !!

It's $94,000
 
1,000 X 100 X 4 = 400,000
