Answer:
Let the height of the larger box = h
and length and width of the larger box = l and w , repectively
Now , Let find the volume of the larger box
Volume = length * width * height
So Volume of the larger box = l*w*h = lwh
Now the question says
the height of the smaller box is 80% of the height of the larger box
It means
Height of the smaller box = 80% of h = 0.80*h = 0.80h
and the other two dimensions are same so it means length and width of the smaller box = l and w
so, Volume of the smaller box = l*w*0.80h = 0.80lwh
So the Difference in the volume of the two boxes = Volume of larger box - Volume of smaller box
therefore , Difference in the Volume of two boxes = lwh - 0.80 lwh = 0.20lwh

Answer:
C: 40 degrees
Step-by-step explanation:
50+2y+y+10=180
60+3y=180
3y=120
y=40
Answer:
y = 2x
Step-by-step explanation:
There is a proportional relation between the number of pairs of socks that Jason buys,x, and the total cost (in dollars), y.
Let us assume that the relation is y = kx ..... (1)
{Where k can be assumed to be the constant of proportionality}
Now, given that Jason can buy 2 pairs of socks for $4.
So, from equation (1), we can write 4 = 2k, ⇒ k = 2
Therefore, the equation (1) becomes y = 2x. (Answer)
Answer:
3 miles per hour
Step-by-step explanation:
he runs 1/3 mile in 1/9 of an hour
then
he runs (we multiply both sides by 9)
9×(1/3) mile in 9×(1/9) of an hour
then
he runs
(9/3) mile in (9/9) of an hour
then
he runs
3 mile in 1 hour
