It took everly 55 minutes to run a 10-kilometer race last weekend. If you know that 1 kilometer equals 0.621 mile, how many mintues did it take everly to run 1 mile during the race?

Answers

Answer:

8.9 minutes

Step-by-step explanation:

Converting Everly Kilometer race to miles

1 km = 0.621 miles

10 km =

10 × 0.621 miles

= 6.21 miles

Hence,

6.21 miles = 55 minutes

1 mile = x minutes

Cross Multiply

6.21 × x = 55 × 1

x = 55 minutes/6.21

x = 8.8566827697 minutes

Approximately = 8.9 minutes

Answers

Answer: it’s D

Step-by-step explanation:

mr cadwell wants to purchase a motorcycle. he has financing options a and b to chose from, as shown below.
Option A-
Down Payment: $1,000
Monthly payment for 3 years: $85

Option B-
Down payment: $1,200
Monthly Payment for 3 years: $85

The purchase of the motorcycle is $3,500, including tax. Based on the info provided in the table, which statement is true?

Option B is better
Option A is better

Answers

Answer:

Option A is better.

Step-by-step explanation:

We will observe both plans one by one to determine which one is better i.e. which one will has less interest to pay.

So,

Option A:

Down Payment: $1,000

Monthly payment for 3 years: $85

The total amount in installments will be:

[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]

The total price of bike will be:

[tex]Total\ price = Downpayment +Installments\\= 1000+3060\\= 4060\\Interest = Total\ price - Purchase \\= 4060-3500\\=560[/tex]

Option B:

Down Payment: $1,200

Monthly payment for 3 years: $85

The total amount in installments will be:

[tex]=Amount\ per\ month * months\\= 85*36\\=3060[/tex]

The total price of bike will be:

[tex]Total\ price = Downpayment +Installments\\= 1200+3060\\= 4260\\Interest = Total\ price - Purchase \\= 4260-3500\\=760[/tex]

We can see that interest in Option A is less than interest in Option B that means Mr. Cardwell will have to pay less amount in Option A.

Hence,

Option A is better.

PLEASE HELP! ILL GIVE YOU BRAINLIEST

Answers

Answer:

In the first picture is B

In the second is C

Step-by-step explanation:

Answer:

the first one is A. 2n + 2 and the second is C. 3(y + 2)

Step-by-step explanation:

So for the first one, 5n + 2 - 3n, is basically combining the factors with the variable n, so you subtract 3n from 5n, giving you 2n + 2, or A.

The second one is kinda reverse. You have to find the one that makes the most sense via Distributive Property. So what you do is separate 3 from the others and put y + 6 in parentheses, like this:

3(y + 6)

But this isn't the answer, as if you do the distributive property with this answer, you would get 3y + 18, and that's not what we want to get. So what we have to do is divide 6 by 3, giving us 2, thus giving us our answer of C.
