Answer:
$34.5
$5,951.5
Step-by-step explanation:
P(x)=27+x
Quantity (x)=210-5x
Income(y)=price×quantity
=(27+x)(210-5x)
=5670-135x+210-5x^2
y= -5x^2+75x+5670
dy/dx= -10x+75=0
-10x=-75
x=-75/-10
=7.5
x=7.5
Maximum income=27+x
=27+7.5
=$34.5
Total income=(27+x)(210-5x)
=(27+7.5){210-5(7.5)}
=(34.5)(210-37.5)
=(34.5)(172.5)
=$5,951.25
The answer is 40, since 25(2) is 50 and 130-50 is 80. 80/2 is 40
Answer:
12
Step-by-step explanation:
4:1:1, from the ratio, you know that there are 6 in total (4+1+1)
so set up a proportion
(4/6) = (48/x)
so... (6 x 48) / 4 = x
x = 72, the total
now repeat to find the value for Pip
(1/6) = (x/72)
72 / 6 = 12
Answer:
-3p+21≥21
Step-by-step explanation:
Answer:
72 ft
Step-by-step explanation:
let height of brob.. (whatever that long name is) be equal to h.
=> h/g = g/l
=> h = 6 x 6 / 0.5
=> h = 36 / 0.5
=> h = 72 ft
