From March 10 to May 12 = 63 days.

63 days / 365 days = 0.1726 years.


Simple interest formula = Interest = Principal X interest rate x time


Interest = 15305.50 - 15000 = 305.50

Principal = 15000

Time = 0.1726 years


Replace the values into the formula:

305.50 = 15000 x Interest rate x 0.1726

Simplify:

305.50 = 2589.041 x interest rate

Solve for interest rate:

interest rate = 305.50 / 2589.041

interest rate = 0.11799 x 100

Rate = 11.80%

Step-by-step explanation:

Count the number of times you have to move the decimal point to the right until it is to the right of the 1st nonzero number.

a) You have to move the decimal point 11 times until it gets to the right of the 1st nonzero number, which is 7. You then rewrite this number as

7.2×10^{-11}

The exponent of 10 is a negative number because you moved the decimal point to the right.

b) Similarly, you have to move the point 9 times to the right so the answer is

9.5×10^{-9}

Factor completely 18x2 − 21x −15. 3(2x 1)(3x − 5) 3(2x − 5)(3x 1) 3(2x − 1)(3x 5) 3(6x 1)(x − 5).
sergeinik [125]

The factor of the 18x^{2} -21x-15 will be 3(3x-5)(2x+1).

<h3>What will be the factor of  18x^{2} -21x-15 ?</h3>

Given quadratic equation is 18x^{2} -21x-15

By taking 3 common from whole of the equation it becomes.

3(6x^{2} -7x-5)

now by factorization equation will be.

3(6x^{2} -10x+3x-5)

3[(2x(3x-5)+1(3x-5)]

Taking (3x-5) common from whole equation it will become

3(3x-5)(2x+1).

Hence the factor of the 18x^{2} -21x-15 will be 3(3x-5)(2x+1).

To know more about factorization follow.

 Solve the system of inequalities and indicate all the integers which are in the solution set:
elena-s [515]
1.) a>10
2.) a<3.5
How I got it: 1.) Subtract 3 from both sides, leaving -2a<10.
2.) Divide by -2 from both sides, remember to flip the inequality sign when dealing with negatives. This leaves you with a>10.
For number 2.) I divided both sides by 5, leaving a<3.5, though this answer may be wrong.
