Answer:
D
Step-by-step explanation:
To write an expression and equation, define the variables.
Taylor purchased three types of items:
x = number of bags of candy
y = number of picture frames
z = number of stickers.
We know she bought 9 items.
So x+y+z = 9.
Answer:
2x-3y=6
X will = 0 Y will = 0
Therefore the x intercept would be 2 and the y intercept would be 6.
This is what i put lol im not sure, i have an A plus in math so this wont hurt it.
Alrighty
squaer base so length=width, nice
v=lwh
but in this case, l=w, so replace l with w
V=w²h
and volume is 32000
32000=w²h
the amount of materials is the surface area
note that there is no top
so
SA=LW+2H(L+W)
L=W so
SA=W²+2H(2W)
SA=W²+4HW
alrighty
we gots
SA=W²+4HW and
32000=W²H
we want to minimize the square foottage
get rid of one of the variables
32000=W²H
solve for H
32000/W²=H
subsitute
SA=W²+4WH
SA=W²+4W(32000/W²)
SA=W²+128000/W
take derivitive to find the minimum
dSA/dW=2W-128000/W²
where does it equal 0?
0=2W-1280000/W²
128000/W²=2W
128000=2W³
64000=W³
40=W
so sub back
32000/W²=H
32000/(40)²=H
32000/(1600)=H
20=H
the box is 20cm height and the width and length are 40cm
The correct answer is 0.56. Hope this helps.
Answer:
{1,2,3,4,5}
Step-by-step explanation:
Natural numbers are positive integers
1,2,3,4,5.......
We need those that are less than 6
