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>
<span>idk if this exactly correct but i tried
1 Find and add the lengths of all the polygon's sides
2.Multiply the lengths of equal sides by the number of equal sides.
3 Multiply a regular polygon's side length by the number of sides.
4 Alternatively, use the area and apothegm of the polygon.

Answer:
The result after adding a set of numbers or is called a sum.
Step-by-step explanation:
Consider the provided information.
The four mathematical operations are:
The sign + is used to add numbers.
The sign - is used to subtract the numbers.
The sign × is used for the product of the numbers.
The sign ÷ is used for division of the numbers.
When we add two or more number by using the operator + the obtained number or value is called the sum of the numbers.
For example:
Consider the number: 2 + 5 if we add the number the resulting value will be 7.
The number 7 is the sum of 2 and 5.
Thus, the result after adding a set of numbers is called a sum.
Answer:
B and D
Step-by-step explanation:
Geometric sequences and series. A geometric sequence is a sequence of numbers that follows a pattern were the next term is found by multiplying by a constant called the common ratio, r.
an = ar^(n-1)
d) 1/3, 2/3, 4/3, 8/3, 16/3, . . . .
1/3 * 2 = 2/3
2/3 * 2 = 4/3
4/3 * 2 = 8/3
where r = 2, constant multiplier is 2. //Answer
b) 320, 80, 20, 5, 1.25, . . . . .
320 * 1/4 = 80
80 * 1/4 = 20
20 * 1/4 = 5
r = 1/4 //Answer
Answer: B and D
//Hope this helps.
