Options A, C, and D are all correct.

0.05x + 0.10y = 1.00 ------------------------- (option A)
 
Multiply by 100 through:
5x + 10y = 100.00    ------------------------- (option C)

DIvide by 5 through:
x + 2y = 20.00         ------------------------- (option D)<span>


The question asked for the standard form, so the answer is Option D.

Answer: Option D

While both a and c work the most likely answer that they want would be A because it represent the cents already and it shows all possible ways that those two values can be split among 1 dollar

If you multiply 2/3 * 6/10, would the product be more than 6/10 or less than 6/10?
Gwar [14]

Answer:

Less than.

Step-by-step explanation:

I have included the explanation in bullet points so it is easier to understand.

We don't even need to solve the problem in order to find out.

  • We know that any number times one is itself
  • We know that any number times less than one would be less than itself.
  • In order to get a product more than 6/10 we would need to multiply it by something more than 1.
  • 2/3 is not more than one, which means the product would be less than 6/10

Hope this helps!

Cam and Madison were investing money into two different accounts. They both invested $550
Arlecino [84]

Answer:

After 5 years, Cam's account will have $ 616.04 while Madison's account will have $ 638.53.

Step-by-step explanation:

Given that Cam and Madison were investing money into two different accounts, both investing $ 550 each, and Cam invested into an account at an annual interest rate of 2.7% compounded monthly while

Madison invested into an account that had an annual interest rate of 3% compounded quarterly, to determine the balances of both accounts after 5 years, the following calculations must be performed:

Cam

X = 550 (1 + 0.027 / 12) ^ 5x12

X = 550 (1 + 0.027 / 12) ^ 60

X = 616.04

Madison

X = 550 (1 + 0.03 / 3) ^ 5x3

X = 550 (1 + 0.03 / 3) ^ 15

X = 638.53

Thus, after 5 years, Cam's account will have $ 616.04 while Madison's account will have $ 638.53.

I need the answer to these problem...I’ve been stuck on it the most.
crimeas [40]

Answer:

1. 2x + 30° = 180°

2x = 150°

x = 75°

2. (2x - 24)° + (x + 12)° + (x - 8)° = 180°

4x - 20 = 180°

4x = 200

x = 50°
