Answer:

C. Round the amount to the nearest $10, remove the zero in the ones place, and double the resulting amount.

Step-by-step explanation:

The percentage is quite present in our day to day, but still generates doubt and confusion at the time of doing the accounts. We use percentages to calculate discounts offered at stores, interest rates on financing, profits obtained from the sale of a particular product, etc.

An easy way to quickly calculate 20% of any invoice value is what is described in letter C.

For example: 20% of 100 dollars is 20 dollars. To calculate this quickly, you must remove the last zero from the number 100 and multiply the remainder by 2.

Removing the last zero from the number 100 will result in the number 10. Multiplying the number 10 by 2, the result will be 20. Thus, one can conclude that the 20% of 100 $ is 20 $.

What is the equation of a line that is perpendicular to y=4x-5 and passes through (-4,6)
lozanna [386]

Answer:

y=-1/4x+5

Step-by-step explanation:

perpendicular lines have slopes that multiply to -1.

Our given line:

y=4x-5

the slope (m) in it is 4. To find the slope of the perpendicular line:

4m=-1

divide by 4

m=-1/4

the slope of the new line is -1/4

here's our equation so far:

y=-1/4x+b

Since the line will pass through the point (-4,6) we can use it to solve for b (y intercept)

so substitute (-4,6) into the equation

6=-1/4(-4)+b

6=1+b

5=b

the y intercept is 5

so our equation is:

y=-1/4x+5

hope this helps! :D
