Answer:
B.
Step-by-step explanation:
-5/-7×-11/-6
= (-5 * -11) / (-7*-6)
= 55 / 42.
A. = - (6/-11) = 6/11
-5/7 * 6/11 = -30/77.
B. - (-11/7) = 11/7
5/6 * 11/7
= 55/42.
-17/2
Step-by-step explanation:
30-8(8)+4y
30=64+4y
30-64=4y
-34=4y
y= -34/4
y= -17/2

Answer: A cardboard box without a lid is to have a volume of 32,000 cubic cm. Find the dimensions that minimize the amount of cardboard used
. ans: base 40 x 40, height = 20
Solution:
The typical box might look like the one below
where . In addition we have xyz = 32000 ,so we need to minimize .
We have,
From the geometry of the problem so y = x. So or x = 40.
Finally, y = x = 40 and z = 32000/(xy)=20.
