Answer:
Step-by-step explanation:
Let the number of dimes be d and quarters be q
<u>The value is $8.80 = 880¢, so:</u>
- 10d + 25q = 880 ⇒ 2d + 5q = 176
<u>If the dimes were quarters and the quarters were dimes, the coins' total value would be $7.30 or 730¢</u>
- 25d + 10q = 730 ⇒ 5d + 2q = 146
<u>Now we have 2 equations. Solving the system by elimination, subtract 5 times the second equation from twice the first equation:</u>
- 2(2d + 5q) - 5(5d + 2q) = 2(176) - 5(146)
- 4d - 25d = -378
- -21d = -378
- d = -378/-21
- d = 18
The answer is 8.5% interest compounded daily.
EXPLANATION
Regardless of your rate, the more often interest is paid, the more beneficial the effects of compound interest.
A daily interest account, which has 360 compounding periods a year, in this case, will generate more money than an account with an annual compounding, which has one compounding period per year.

I just took this lesson
Answer:
Let A be the area of the dilated triangle.
Given the statement: A triangle with an area of 2/3 cm2 is dilated by a factor of 6.
⇒ Pre-image triangle has an area =
Scale factor(k) states that the dimension of the Dilated-image is 6 times longer than the dimensions of the pre-image.
i.e,
Substitute the given values to find the value of area of dilated triangle.
or
Multiply both sides by 2 we get;
Divide both sides by 3 we get;
Therefore, the area of the dilated triangle is,
Hi.
For this, you do:
4% of 7500 = 300
He is given $300 per year, for two years.
1st year= 7500+300= 7800
2nd year= 7800+300= 8100
answer= $8100
Hope this helps:)
