Answer: B
Step-by-step explanation:
-195.79 is the lowest out of all of the numbers.
Answer:
the original is 1080.
Step-by-step explanation:
80%×600=480
480+600=1080
Suppose you cut squares have the side lengths x then we have
length of base box=20-2x
width of base box=30-2x
height of box=x
volume of the box
V=x(20-2x)(30-2x)
V=600x-100x^2+4x^3
then
dV/dx=600-200x+12x^2
set that to zero
600-200x+12x^2=0
apply quadratic formula
x=approx12.97 or 3.92
since you want in whole numbers so x=13 or x=4
so if x=13 then V= -312 but negative number doesn't make a sense so we ignore that
if x=4 then v=1056 this is the greatest volume
the dimensions are
length of a box base=12
width of a box base=22
height of box =4
did u get it ?
Answer:
r=7
Step-by-step explanation:
5r-7=2r+14
add sevento both sides
5r=2r+21
Subtract 2r from both sides.
3r=21
divide both sides by 3
r=7
Answer:
r = -5
Step-by-step explanation:
common ratio (r) is found be dividing one term by its preceding term:
r = 275 ÷ -55 = -5
or, r = -55 ÷ 11 = -5
Therefore, r = -5
