Answer:
Salesprice =$25000
Step-by-step explanation:
comission=$ 2300;10
salespreice=x:100
x=2300*100/10=$23000
dealership fee= $2000
salesprice= $25000
Answer:
96.
Step-by-step explanation:
Divide the silver beads by 85=96
Then divide the black beads by 30=96.
Total necklaces that can be made: 96
Answer:
Dimensions :
x (the longer side, only one side with fence ) = 90 ft
y ( the shorter side two sides with fence ) = 45 ft
Total fence used 45 * 2 + 90 = 180 ft
A(max) =
Step-by-step explanation: If a farmer has 180 ft of fencing to encloses a rectangular area with fence in three sides and the river on one side, the farmer surely wants to have a maximum enclosed area.
Lets call "x" one the longer side ( only one of the longer side of the rectangle will have fence, the other will be along the river and won´t need fence. "y" will be the shorter side
Then we have:
P = perimeter = 180 = 2y + x ⇒ y = ( 180 - x ) / 2 (1)
And A (r) = x * y
A(x) = x * ( 180 - x ) /2 ⇒ A(x) = (180/2) *x - x² / 2
Taking derivatives on both sides of the equation :
A´(x) = 90 - x
Then if A´(x) = 0 ⇒ 90 - x = 0 ⇒ x = 90 ft
and from : y = ( 180 - x ) / 2 ⇒ y = 90/2
y = 45 ft
And
A(max) = 90 * 45 = 4050 ft²
Answer:
p^(a-1)
Step-by-step explanation:
The simplified expression can be seen in the picture attached below
As the factors have the same base, we just need to add or substract the exponents
p^(a-3+2) = p^(a-1)
