A. You would use base*height (bh). You would multiply 4 and 5. The answer is 20in.
B. It would be 1/3*bh. The answer would be 6.6.
Answer:
B
Step-by-step explanation:
Given
sinΘ = 
, then
Θ = 
( ) = 45° → B
SA=2H(L+W)+LW for open box
20=2H(4+W)+4(W)
distribute
20=8H+2WH+4W
divide both sides by 2
10=4H+WH+2W
solve for 1 variable, pick W
10-4H=WH+2W
10-4H=W(H+2)
(10-4H)/(H+2)=W
V=LWH
subsitute 4 for V, subsitute H for H and (10-4H)/(H+2) for W
V=(4)(H)(10-4H)/(H+2)
V=(40H-16H²)/(H+2)
find max value
take deritivitive of this thing
V'=-16(H²+4H-5)/((H+2)²)
using sign chart
sign changes from positive to negative at H=1
so at H=1
find W
W=(10-4H)/(H+2)
W=2
the dimeionts are
length=4ft
width=2ft
height=1ft
(the volume is 8 cubic feet)
I have no idea I’m doing the same thing rn but good luck bro bro
Answer:
6 days
Step-by-step explanation:
I know this because you would divide 6 women by 3 to get two women so you would multiply the two days by 3 to get 6 days
