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.
Answer:
x = 18
Step-by-step explanation:
When two parallel lines are intersected by a transversal, then same-side exterior angles are supplementary, meaning their angle measures add up 180 degrees. Applying this knowledge here, one can state that;
( 6x - 3 ) + 75 = 180
Simplify,
6x - 3 + 75 = 180
6x + 72 = 180
Inverse operations,
6x + 72 = 180
-72 -72
6x = 108
/6 /6
x = 18
Answer:
i am correct :))))))))))) hope this helped
<span>y = |x − 1|→y=x-1, if x-1>=0
y=-(x-1), if x-1<0
Then if x-1>=0→x>=1, y=x-1
if x-1<0→x<1→y=-(x-1)=-x+1→y=-x+1
For x>=1
y=x-1
y=3x+2
Solving for x by equaliting's method:
y=y→3x+2=x-1→3x+2-x-2=x-1-x-2→2x=-3→2x/2=-3/2→
x=-3/2<1 No solution
For x<1
y=-x+1
y=3x+2
</span>Solving for x by equaliting's method:
y=y→3x+2=-x+1→3x+2+x-2=-x+1+x-2→4x=-1→4x/4=-1/4→
x=-1/4<1 Ok
<span>
y=-x+1
y=-(-1/4)+1
y=1/4+1
y=(1+4)/4
y=5/4
The approximate solution of this system of equations is
(x,y)=(-1/4,5/4)=(-0.25,1.25)
