The 1st and 3rd choices are irrational. The other 2 are rational. Irrational numbers are numbers that you can't make a simple fraction out of.
Answer:
Step-by-step explanation:
The smallest angle is opposite to the smallest side.
<u>Use the law of cosines to find the angle opposite to side with the length of 10 cm:</u>
- cos A = (b² + c² - a²)/(2bc)
- cos x = (11² + 13² - 10²)/(2*11*13)
- cos x = 190/286
- cos x = 0.664 (rounded)
- x = arccos (0.664)
- x = 48.4° (rounded)
Answer:
$221.44
Step-by-step explanation:
As the bank charges a <em>monthly </em>interest, we cannot calculate a simple or compound interest over the 8 month period. As the balance will decrease each month as Kylie makes payments, the interest applied each month will also decrease. Therefore, we have to use:
<u>Monthly Payment Formula</u>

where:
- PMT = monthly payment
- P = loan amount
- i = interest rate per month (in decimal form)
- n = term of the loan (in months)
Given:
- P = $1,700
- i = 0.925% = 0.00925
- n = 8 months
Substituting the given values into the formula and solving:

Therefore, the monthly payment to the nearest dollar will be $221.44
Answer:

Step-by-step explanation:
Since the angles are equal the equation to solve would be:

you will subtract 3x from 5x and get 2x

subtract 20 from 50 to get 30

divide each side by 2
