So you have to solve for "donation" - so let's call that X. And the things we know are what the grandfather donated, as a function - meaning based upon - Theo's donation. We'll call that Y.

So Y is equal to 1/2 of $4 plus Theo's donation...... 0.5*(x+4).

So... 4.25 = 0.5(X+4), solving for X

4.25=0.5x + 2

-2            -2

2.25=0.5x - divide each side by 0.5 to get x alone.

x = 4.50

Plugging back in:

(4.50 + 4.00)*0.5 = 4.25!

A bank is offering you an introductory credit card promotion. Your interest for the first year is 8%. But, at the beginning
Art [367]

Answer:

  • c) $22.50

Explanation:

<u>1. Calculate the monthly interest owed during year 1</u>

<u />

  • <em>Interest for first year: 8%</em>

  • The monthly rate is the yearly rate divided by 12: 8% / 12 = 0.08/12

  • The monthly interest owed is the monthly rate times the balance: (0.08/12)×$1,800 = $12.00

<u>2. Calculate the monthly interest owed during year 2</u>

<u />

  • <em>Interest for second year: 23%</em>

  • The montly rate is the yearly rate divided by 12: 23% / 12 = 0.23/12

  • The monthly interest owed is the monthly rate times the balance: (0.23/12)×$1,800 = $34.50

<u>3. Calculate the difference</u>

  • Difference in the monthly interest owed during year 1 and year 2 = $34.50 - $12.00 = $22.50

Hence, the answer is the option c) $22.50

6^4 • 3^4 and 18^8, Are the expressions equivalent? I’m only talking about C in the photo.
Afina-wow [57]

Hey there!

6^4 * 3^4 = ?

6^4

= 6 * 6 * 6 * 6

= 36 * 36

= [1,296]

3^4

= 3 * 3 * 3 * 3

= 9 * 9

= [81]

1,296 * 81

= [104,976]

6^4 * 3^4 = [104,976]

Now let’s see if 18^8 is equivalent to 18^8

18^8

= 18 * 18 * 18 * 18 * 18 * 18 * 18 * 18

= 324 * 324 * 324 * 324

= 104,976 * 104,976

= [11,019,960,576]

Therefore, 11,019,960,576 ≠ 104,976 because It is way too big to be equations answer

Answer: [NO], they aren’t equivalent because 18^8 is too big to equal to 6^4 * 3^4

Good luck on your assignment and enjoy your day!
