Answer:
$141,557.76
Step-by-step explanation:
Chao bought a boat for 160,000
The value of the boat reduces by 4% every year
Therefore the value of the most at the end of three years can be calculated as follows
= 100%- 4%
= 96%
= 160,000 × 96/100^3
= 160,000 × 0.96^3
= 160,000 × 0.884736
= 141,557.76
Hence the price of the boat after 3 years is 141,557.76
#1.
[4x = -12y + 16 and x + 3y = 4]
One answer
#2.
Here, y = 4x + 3
y - 4x = 3
Multiply by 2,
2y - 8x = 6
Compare with second equation,
6 ≠ 3
In short, System of Equation does not have any solution. [ Option D ]
#3.
2y=6
3x-6y=18
Divide first equation by 2: y=3
Substitute y=3 into second equation: 3x-6(3)=18
Solve for x: 3x=36 x=12
Therefore there is only one solution: x=12 y=3
#4.
y - 7x = -14
7y - 49x = -2
Rewrite the first equation as "y =" so that it can be substituted into the second equation and solve for x.
y = 7x - 14
7(7x - 14) - 49x = -2
49x - 98 - 49x = -2
-98 = -2
Since the variables cancel and the equation is not true there is no solution.
The lines are parallel and will not intersect.
Answer:
Step-by-step explanation:
The weight of an object is the magnitude of the force of gravity acting on the object. It is equal to the product between mass of the object (m) and acceleration of gravity (g):
In this problem, we have 100 sharks; the weight of each shark is
When we have n objects, the total weight of the n object is n times the weight of each object:
Therefore, since in this case
n = 100
The total weight of the 100 sharks is:
