Let
b-----------> the length side of the square box
h------------> the height of the box
SA---------> surface area of the box
we know that
[volume of the box]=b²*h
volume=256 in³
b²*h=256-------> h=256/b²-----> equation 1
surface area of the box=area of the base+perimeter of base*height
area of the base=b²
perimeter of the base=4*b
surface area=b²+(4*b)*h------> SA=b²+4*b*h-----> equation 2
substitute equation 1 in equation 2
SA=b²+4*b*[256/b²]-----> SA=b²+1024/b-----> SA=(b³+1024)/b
the answer is
the formula of the volume of the box is V=b²*h-----> 256=b²*h
the formula of the surface area of the box are
SA=b²+4*b*h
SA=(b³+1024)/b
Answer:
m∠PNO = 60°
m∠O = 33°
Step-by-step explanation:
∡NPO is 87° because it's a vertical angle with the 87° angle
3) ∡PNO is supplementary to the 120° angle (they must add to 180°)
4) m∠O = 180 - (60 + 87) = 33
Answer:
x + y = 330 and 9x + 16y = 4650
Step-by-step explanation:
At a museum, the admission price for children is $9 and the admission price for adults is $18. The total amount the museum collects in admissions for the day is $4959. The total number of visitors is 319.
x = number of children
y = number of adults
x + y = 330
9x + 16y = 4650
Answer:
<em><u>M(-2,-6)</u></em>
y-axis (-2,6)
x-axis (2,-6)
<u><em>N(4,1)</em></u>
y-axis (4,-1)
x-axis (-4,1)
Step-by-step explanation:
When the point is reflected across the x-axis then the y value will change signs.
When the point is reflected across the y-axis then the x value will change signs
Scientific notation is always less than 1. If you had the decimal at 7.83, then it is less than one. 00000007.83. count from the decimal all the way to the left making it 7 jumps to the left to make 0.000000783. So it’ll be 7.83 x 10 to the power of -7
