Answer:
Step-by-step explanation:
Triangle ABC is a right angle triangle that is made up of 2 right angle triangle.
To determine y, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side²
15² = y² + 12²
225 = y² + 144
y² = 225 - 144 = 81
y = √81 = 9
To determine z,
20² = z² + 12²
400 = z² + 144
z² = 400 - 144 = 256
z = √256 = 16
If the CPI for 1989 was 124, the rate of the inflation between the base period and 1989 was 24%!
Hi,
The total amount is 17.91608
How I got my answer:
100 + tip%/100 * 14.56 = amount with tips
100 + 15/100 * 14.56
115/100 * 14.56
1.15 * 14.56 = 16.744
100 + tax%/100 * amount with tips = total amount
100 + 7/100 * 16.744 = total amount
107/100 * 16.744
1.07 * 16.744
17.91608 = total amount
Hope this Helps you.
Answer:
