Milo can run 9 miles in 60 minutes. He needs to reduce his time by 10%. Approximately how many minutes does he have to take off his time? Round to the nearest whole number.

Answers

Multiply 60 minutes by 10 %

60 x 0.10 = 6

Answer: 6 minutes

the answer is 6 minutes because if you multiply 60 * 0.10 you will get 6 and that’s how much Milo has to reduce in her time

Zachary purchased a computer for $1,600 on a payment plan. Two months after he purchased the computer, his balance was $1,370. Four months after he purchased the computer, his balance was $1,140. What is an equation that models the balance y after x months?

Answers

Answer:

Step-by-step explanation:

You are finding out each time how much is the items Zachary bought.

Then inputting a equation

$1,600 - ??? = $1,370

To find the unknown number, you must subtract the 2 original numbers.

$1,600 - $1,370 = $230

Computer costs: $230 leaving Zachary with $1,370 left.

Next, it says he purchased another computer...

$1,370 - ??? = $1,140

Again, we subtract the 2 original numbers to find the unknown.

$1,370 - $1,140 = $230 leaving Zachary with  $1,140 left.

Now we input this data into an equation...

y = -230x + 1600.

Answers

Answer:

A

Step-by-step explanation:

Sila put a wrong number in her calculator

Sila jogged 12 kilometers today and wants to know how far she traveled in feet. What error did Sila make while converting from kilometers to feet ? The correct answer is Option a) Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction = 392,832 feet.

Sila's mistake can be identified in her conversion calculation. She first needs to convert kilometers to miles and then miles to feet. Let's break down the process step by step:

1. Kilometers to Miles:

Start by converting kilometers to miles.

There are 0.62 miles in 1 kilometer.

So, the first fraction is correct:

Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction.

2. Miles to Feet:

Next, convert miles to feet.

There are 5280 feet in 1 mile. Sila's calculation is incorrect at this step. The correct fraction to use here is Start Fraction 5280 feet Over 1 mile End Fraction.

Now, let's put it all together:

- Start Fraction 12 kilometers Over 1 End Fraction times Start Fraction 0.62 miles Over 1 kilometer End Fraction times Start Fraction 5280 feet Over 1 mile End Fraction

Multiply the fractions step by step:

- 12 kilometers * 0.62 miles/kilometer * 5280 feet/mile

- This simplifies to 392,832 feet.

So, Sila's error lies in not using the correct conversion factors for both kilometers to miles and miles to feet.

The correct conversion factors should be applied in sequence, leading to the final answer of 392,832 feet traveled.

Answer:

He has 286 dollars in his bank account at the end of the month.

Step-by-step explanation:

Deposit Meaning- basically to add

Withdrawal- basically to subtract

154+237+45= 436

-125-25= -150

436-150= 286

I think the last answer is wrong. No offense. If he starts with $154 and I deposited 237 bring it Up to 391 then he withdraws $25 so you subtract that and you get 366 then he withdraws another 125 bringing it down to 241 then he deposits $45 bringing him up to 286. 286 is your answer and make sure you put dollars as the unit.
