The simple interest formula is A = P(1 + rt) in which A is the total of money after interest, P is your principal (starting) amount, r is the interest rate, and t is the amount of time.
For 1), plug in your variables to get A = 1500(1 + (7/100*1.5)). Simplify, and you'll get A = 1500*1.105, and finally your answer, $1,657.50.
<span>For 2), add your interest and principal amount, then plug in your variables to get 676 = 520(1 + 5r). Distribute to get 676 = 520 + 2600r. Subtract 520 from 676 to get 156 = 2600r, then divide both sides by 2600 to get a rate of 0.06, or 6%.
For 3), add your interest and principal amount, then plug in your variables to get 1599 = 1300(1 + 5.75t). Distribute to get 1599 = 1300 + 7475t. Subtract 1300 from both sides to get 299 = 7475t, and then divide both sides by 7475 to get .04 = t, or a time period of four years.
The other two problems can be solved using the formula and steps described above. If you still need help with them, leave a comment and I will solve those as well. </span>
Answer:
c = 7√2
Step-by-step explanation:
Apply pythagorean theorem to find the third side.
Thus, c² = a² + b²
where, c is the third side and a and b are the other sides.
Plug in the values
c² = 8² + (√34)²
c² = 64 + 34
c² = 98
c = √98
c = √(49 * 2)
c = 7√2
Answer: 3 the actual answer is 2.995421844
Step-by-step explanation:
1 ) 116/17 = 7.1875 which is 5.1875 from 2, 17/8 is 2.125 which is 0.125 from 2 and 63/32 is 1.968 which is 0.032 from 2. 63/32 is the closest to 2.
Answer:
the balance after 5 years is: 26540.744
Step-by-step explanation:
Given the information:
- P = initial balance = $ 20,000
- r = interest rate (decimal) = 5% = 0.05
- n = number of times compounded annually = 4
- t = time = 5
We have the compound interest function ta model the situation is:
<=> A = 
<=> A = $26540.744
Hence, the balance after 5 years is: $26540.744
