Step-by-step explanation:
Law of Cosines
x = √(40²+12² - 2·40·12·cos(37°)) ≅ 31.3 units
Step-by-step explanation:
The first thing we have to do before we can actually do the problem is turn the words into a math equation.
If we use <em>x </em>as our "number," we see that "The sum of a number and 2" can also be written as <em>x</em>+2. The word "Is" almost always means (=), so now we have (<em>x</em>+2) = . The very last part, "6 less than twice that number," means 2<em>x - </em>6.
So, our whole equation is, (<em>x </em>+ 2) = (2<em>x </em>- 6), which simplifies to -<em>x </em>= -8, or
<em>x</em> = 8
Answer:
$206
Step-by-step explanation:
The amount that would be in the account = amount deposited + interest earned on deposit
interest earned on deposit can be determined by determining the simple interest
Simple interest = principal x time x interest rate
principal = the amount deposited = $200
Time = the duration of the deposit = 1 year
interest rate = the percentage on deposit that would be earned = 3%
200 x 0.03 x 1 = $6
The amount that would be in the account = $200 + $6 = $206
200 because 20 times 10 is 200
