Answer:
There could be any number of dimensions as long as the two dimensions multiply to 8/9
Step-by-step explanation:
One example of this would be 2 by 4/9
2 * 4/9 = 8/9
First you need to set up a formula. Underline all of your givens:
<u>Spent 1/2 on clothes
$6 more for washing windows
Ended with $10.
</u>
now you need to set up an equation.
<u>
</u>You know she ended up with $10. So that will be what it equals. Then you know that she earned $6 in addition to her allowance. So this would be (x= allowance) (x+6)/2 = 10.
<u>
</u>Now you need to solve for x.
Multiply both sides by 2.
<u>
</u>x+6=20<u>
</u>Now subtract both sides by 6 to get x alone:
<u>
</u>x=$14<u>

Answer:
Brian will have £817.8
Step-by-step explanation:
Principal = £4700
interest = 5.5% = 0.055
n = 3 years
Amount = [(Principal * (1 + interest)ⁿ) - Principal]
Amount = [(4,700 * (1 + 0.055)³) - 4,700]
Amount = [(4,700 * (1.055)³) - 4,700]
Amount = [(4,700 * 1.174) - 4,700]
Amount = [5,517.8 - 4,700]
Amount = £817.8
