Answer:
-41/80, -45/80, -48/80, -51/80, -55/80, -59/80
Step-by-step explanation:
-4/8, -3/4 = -4/8, -6/8
= -40/80, -60/80
∴ Rational numbers between -40/80 and -60/80 = -41/80, -45/80, -48/80, -51/80, -55/80, -59/80.
Answer:
Option C: -$1500 is the correct answer.
Step-by-step explanation:
Given that:
Total amount invested in business = $24,000
Loss suffered in first quarter = $4500
As the amount is shared by Brian, Steve and Rita equally, therefore,
Loss of each person = 
Loss of each person = 
As loss is defined by decrease in the investment,
Loss of each person = -$1500
Hence,
Option C: -$1500 is the correct answer.
4(4a 7 ) 3(2a 5) = 4 ( 4 x 5 x 7 ) x 3 ( 2 x 5 x 5 ) = 560 x 150 = 84000
Answer:
39
Step-by-step explanation:
Yield goes down 1 lb for each tree over 23 per acre, so the yield per tree as a function of x trees per acre is ...
yield per tree = 55 -(x -23) = 78 -x . . . . . pounds of cherries
To get the yield per acre, we multiply the number of trees per acre by the yield per tree:
lb/acre = (x tree/acre)((78 -x) lb/tree) = x(78 -x)
This is a quadratic function that opens downward and has zeros at x=0 and x=78. The vertex (maximum) is on the line of symmetry, halfway between the zeros. The yield per acre will be a maximum when ...
x = (0 +78)/2 = 39 . . . . trees per acre
39 trees should be planted per acre to maximize yield per acre.
