20.09 → only one with decimal in the hundreds, not tens
Answer:
Step-by-step explanation:
The Hypotenuse of triangle, H = 25 cm
Base = 15 cm
Height = 20 cm
We need to find the area of the triangle. The area of a right-angled triangle is given by :
So, the area of the triangle is equal to 
.
X-3y=18
X always has a 1 in front of it so
1x-3y=18
-1x -1x You will have to get -3y by its self.
-3y=-1x + 18 when you move 1x over the = it turns into a -1x
/-3 /-3 /-3 divided everything by -3 to get y by its self
Y= 1/3 - 6 and that is you answer
So 1/8 per month
1/8 * 12 months = 3/2
Reduced is 1 1/2 inches per year
100%-20%= 80%=0.8
115(0.8)= 92
92(1.075)= 98.9
The final price of the coffee table is $98.90.
Hope this helps!
