In ΔNOP, the measure of ∠P=90°, the measure of ∠N=83°, and NO = 83 feet. Find the length of OP

Answers

Answer 1
Answer:

Answer: Length OP = 82.38 feet

Step-by-step explanation: Given that the ΔNOP, the measure of ∠P=90°, the measure of ∠N=83°, and NO = 83 feet.

We can find the length of OP by using trigonometry ratio since it is a right angle

NO = hypothenus and

OP = opposite

Sin 83 = OP/NO

Sin83 = OP/83

OP = 83sin83

OP = 82.38 feet

How can you change linear equation in form ax+by=c to y=mx+b form and vice versa

Answers

Arithmetic operations can be used to change linear equations in form ax+by=c to y=mx+b form and vice versa and this can be determined by simple subtraction and division operation.

Given :

ax + by = c

y = mx + c

The following steps can be used to change the linear equation in form (ax+by=c) to (y=mx+b) form:

Step 1 - Write the equation.

ax + by = c

Step 2 - Subtract ax from both the sides in the above equation.

ax + by - ax = c - ax

by = c - ax

Step 3 - Divide by 'b' from both sides in the above equation.

y = (-a)/(b)x+(c)/(b)

By following the above steps equation (ax + by = c) can be converted into (y = mx + c).

The following steps can be used to change linear equation in form (y = mx + c) to (ax + by = c) form:

Step 1 - Write the equation.

y = mx + c

Step 2 - Subtract mx from both sides in the above equation.

y - mx = c + mx -mx

y - mx  = c

By following the above steps equation (y = mx +c) can be converted into (ax + by = c).

For more information, refer to the link given below:

You simply have to take the linear equation form (ax + by = c) and solve for y. So you get:
by = c - ax
y = c/b - ax/b

Since c/b will be a constant, you can replace it with any variable (i.e. b), and so that represents the y-intercept and a/b will also be a constant, so that can also be replaced by any variable (i.e. m), and it represents the slope.

A salesperson receives a 2.5% commission on sales, what commission does the salesperson receive for $8,000 in sales

Answers

Percentage of commission received by the salesperson = 2.5%
Amount of sales made by the salesperson = $8000
Then
The amount of commission received by the salesperson = (2.5/100) * 8000 dollars
                                                                                             = 2.5 * 80 dollars
                                                                                             = 200 dollars
So the salesperson receives a commission of $200 on the total sales made. I hope the procedure is clear enough for you to understand. You can use this method in future for solving similar problems without requiring any help from outside.
