Answer:
The correct answer is C) 5
Step-by-step explanation:
7 + (2x - 7)
2 x 5 - 7 = 3
7+3 = 10
x+5
5+5 = 10
It's 14 3/10 as a mixed number.
Answer:
18 + √3
Step-by-step explanation:
The product of a surd and its conjugate gives a rational number. Hence;
(18 - √3) (18 + √3)
=324 + 18√3 - 18√3 - 3
=321
A rational number does not contain any surd, hence the answer.
Answer:
$12320
Step-by-step explanation:
Given data
Cost of car= $17500
rate of depreciation= 11%
duration= 2003 - 2006= 3 years
Let us apply the compound interest formula
A= P(1-r)^t
Note the negative sign(this is because of the depreciation)
A=17500(1-0.11)^3
A= 17500(0.89)^3
A= 17500*0.704
A= $12320
Hence the value of the car is $12320
