Salesperson receives 6.5 percent commission. Sells for $23,999, how much money did he make in commission
VLD [36.1K]

Answer:

$ 1,559.935

Step-by-step explanation:

Given that the salesman receives 6.5% of total sale made as commission

Total amount of sale = $23999

Therefore, commission received by salesman = 6.5% of 23999

When a number is decreased by 4%, the result is 93. What is the original number
romanna [79]

Answer:

<u>The original number is 96.875</u>

Step-by-step explanation:

Let's find the original number using the Direct Rule of Three, this way:

       Percentage          Number

              100                       x

               96                       93

***********************************************

96x = 93 * 100

96x = 9,300

x = 9,300/96

x = 96.875

<u>The original number is 96.875</u>

Determine whether a triangle with given side lengths will be a right triangle?
mr Goodwill [35]

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorrem.  Find the sum of the squares of the two shortest sides and determine whether this sum equals the square of the longest side:

#19:  5^2 + 12^2 = ? = 13^2

 25  +  144  = ? = 169    This is true, so you do have a right triange in #19.

#21:  2^2 + 4^2 = ? = 7^2, or 4 + 16 = ? = 49     This is false.  Not a right

                                                                            triangle.

Apply this same approach (Pythagorean Theorem) to the remaining problems.

Simplify. 2+35x−1−15x 1+25x 3−45x 1−25x 3+25x
Lelu [443]

Answer:

Option A is correct.

1+\frac{2}{5}x

Step-by-step explanation:

Simplify: 2+\frac{3}{5}x - 1 -\frac{1}{5}x                ......[1]

Like terms are those terms who have same variable to the same power.

Combine like terms in [1] ,we have;

1+(\frac{3}{5}x- \frac{1}{5}x)

Simplify:

1+\frac{2}{5}x

Therefore, the simplified form of  2+\frac{3}{5}x - 1 -\frac{1}{5}x  is, 1+\frac{2}{5}x
