Answer:
$11.250
Step-by-step explanation:
Percentage of Decrease = 25%
To know the cost of the car when she bought it, we must first know the amount of depreciation. After that, we then subtract the value from the new price.
Therefore:
25% of $15,000
= 25 / 100 * $15,000
= 0.25 * $15,000
= $3750.00
The value of the percentage of Decrease is $3750.00.
To know the worth of the car when she bought it:
$15,000.00 - $3750.00
= $11.250.
The worth of the car when she bought is $11.250
Answer:
x = -2π5, x = 2π5
Step-by-step explanation:
The absolute value sign just mean that both the negative and positive value in the |...| would give you the answer. Remember how |7|=7 and |-7|=7 too?
In this case
sin(2π5) = |sin x|
is the same as...
- sin(2π5) = sin(x)
- sin(2π5) = -sin(x)
solve for x in these two cases.
In case (1) sin(2π5)= sin(x)
sin(2π5) = sin(x)
The stuff inside the parentheses must e the same so x=2π5.
In case (2) sin(2π5) = -sin(x)
A property of sine is that it's an odd function. This means you can move the negative sign outside the parentheses and put it inside: sin(-x) = -sin(x). So lets do that to our problem.
sin(2π5) = -sin(x)
sin(2π5) = sin(-x)
as we can see, the stuff inside the parentheses must be so the same, so
2π5 = -x
-2π5 = x
Answer:
Laila gets £470
Step-by-step explanation:
Let John's share=x
Laila's share=x+80
The sum of their individual shares should equal 860
therefore x+x+80=860
2x=860-80
2x=780
x=390
Therefore each person's share:
John-£390,Laila-£470
Answer:
A=0.83 cube root
Step-by-step explanation:
V^3=90=(6*A)^3
so A^3=90/6^3=90/108
so A = 0.83 cube root
