ICE Princess25 [194]

Answer: Red copper = $0.12 per meter

Yellow copper = $0.22 per meter

A blank CD can hold 70 minutes of music. So far you have burned 25 minutes of music onto the CD. You estimate that each song las

zaharov [31]

Answer:

The possible numbers of songs that you can burn onto the CD is 11.

Step-by-step explanation:

The total storage capacity of CD = 70 minutes

Storage already used = 25 minutes

Hence, The available storage = Total available storage - Used Storage

= 70 minutes - 25 minutes = 45 minutes

Hence, the CD has 45 minutes storage left.

Now, each song takes up 4 minutes of storage.

⇒ $\textrm{Total number of songs possible} = \frac{\textrm{Total storage left}}{\textrm{Time taken by each song}}$

= $\frac{45 minutes}{4minutes } = 11.25$

⇒The number of songs possible = 11.25 ≈ 11

Hence, the possible numbers of songs that you can burn onto the CD is 11.

Assume a loan balance of $174,000, a monthly payment of $1,395, and an interest rate of 8%. On next month's payment, how much of

o-na [289]

Given a loan balance of $174,000 and an interest rate of 8%, the interest due for the next months payment is given by

$\frac{0.08(174,000)}{12} \right)= \frac{13,920}{12} =\$1,160$

Therefore, the amount out of the monthly payment of $1,395 that will be applied to the principal is $1,395 - $1,160 = $235.
