$11,000 will bet the cost in 7 years
Given:
Original cost: $25,000
Depreciation rate: 8%
Term: 7 years
Formula for Depreciation:
A = C ( 1 - ( r ) (t) )
A = Future Value
C = Original Cost
r = rate
t = term
Solution:
Substitute the given values to the formula for depreciation.
A = $25,000( 1 - ( 0.08)(7))
A = $25,000( 1 - .56 )
A = $25,000(0.44 )
A = $11,000
Answer:
3.7feet
Step-by-step explanations
Using the sin rule
A/sin a = B/sin b
Let A = PQ = 8.5feet
B = QR = x feet
a = R = 90°
b = P = 26°
Substitute the values into the Sin rule
8.5/sin90 = x/sin26
8.5×sin 26 = x × sin 90
8.5×0.4383 = x× 1
3.7255 = x
Hence the length of QR to the nearest tenth 3.7feet
X=20
3(x-1)-8=4(1+x)+5
1. Distribute
3x-3-8= 4+4x+5
2. Combine like terms
3x-11=4x+9
3. Add 11 or subtract 9 to both sides
3x-11+11=4x+9+11
or
3x-11-9=4x+9-9
3x=4x+20
or
3x-20=4x
If you did the first step then you subtract 4x from both sides
3x-4x=4x+20-4x
-x=20
Then you would divide by a negative 1 because there is an imagery 1 in front of the x.
-x/-1=20/-1
x=-20
If you did the second way then you would subtract 3x from both sides
3x-20-3x=4x-3x
-20=x
And you get the same answer for both ways
