Answer:
Step-by-step explanation:
Recall that the perimeter of a shape is found by adding each of the sides together.
If the lengths of the sides are , then the perimeter would be
The original price is 30$ because we know that the new price is worth 60% of the old price. We can set up an equation to model this: 0.60x = 18. Dividing both side by 0.60 gives us an original value of 30. If you take 40% off of 30 you get 18 — allowing us to check our work.
Answer:
The balance of the account is $1335.6
Step-by-step explanation:
To find the new balance of the account after 212 years, we use simple interest formula to calculate that.
Principal = 450
Rate = 0.35% quarterly = (0.35*4) annually = 1.4% = 1.4 / 100 = 0.014
Reason why the rate was converted from quarterly to annually is because simple interest are calculated annually
T = 212 years
Simple Interest (S.I) = ?
S.I = PRT
S.I = 450 * 0.014 * 212
S.I = $1335.6
The balance of the account after 212 years is $1335.6
Step-by-step explanation:
The roots of this equation would be -1/3 and -3.
