Answers

Answer:

The winning time increased by an average of 0.4 second per year from year 2 to year 4.

Step-by-step explanation:

I just took the quiz

The winning time for a race displayed in the table would be:

A). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

Find the increase in winning time:

Given that,

Year                             Winning Time(seconds)

1                                          27.5

2                                         28.4

3                                         28.7

4                                         29.2

5                                         29.44

The total change in the time = (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, option A is the correct answer.

You open a savings account with a beginning balance of $600. You plan on depositing $50 every month until you have enough money to purchase a car which costs $2500. However, your parents remind you that it's probably not a good idea to empty your entire savings account so they recommend leaving a balance of $500 in your account. How many months will it take you to have enough money saved to purchase the car AND still have a $500 balance? Set up an equation and solve. ​

Answers

Answer:

48 months

Step-by-step explanation:

first take how much you need and add how much you want to leave, so 2500+500=3000. Then delete 600 from 3000, which will give you $2400. divide $2400 by 50 which gives you 48. it will take 48 months to get enough money to purchase a car at $2500 and leave $500 in the account.

Ciara is making a new dance outfit. She needs 2 1/2 yards of fabric for the shawl. She needs 1 3/4 yards of fabric for the dress. If she has 3 yards of fabric, how much more does she need. If each yards of fabric cost 7.98, How much money does she need.

Answers

Answer: See explanation

Step-by-step explanation:

Amount of yards of fabric for the shawl = 2 1/2

Amount of yards of fabric for the dress = 1 3/4

Total amount of yards needed

= 2 1/2 + 1 3/4

= 2 2/4 + 1 3/4

= 3 5/4

= 3 + 1 1/4

= 4 1/4

Since she has 3 yards of fabric, the number of yards needed more will be:

= 4 1/4 - 3

= 1 1/4

If each yard = 7.98, the amount needed will be:

= 1 1/4 × 7.98

= 1.25 × 7.98

= 9.975
