Answer:
960cm³
Step-by-step explanation:
Find the base of the triangle (use phytagoras theorem)
c²= a²+b²
20²= 16²+b²
400=256+b²
b²=400-256
b²= 144
b=
base= 12
Volume: (1/2×b×h)×l
= (1/2×12×16)×10
=(6×16)×10
=96×10
=960cm³
Answer:
8
Step-by-step explanation:
The equation of the parabola can be represented as
for some constant a.
Since the coefficient of x² is 2, a = 2, so
So, the answer is 8.
The price of car is $18000
Step-by-step explanation:
Given
Sales tax on car = $1080
Rate = 6%
Let x be the price of the car
We know that as the rate of sale tax is 6%, 6% of x is 1080
Using mathematical notation
0.06x = 1080
Dividing both sides by 0.06
Hence,
The price of car is $18000
