so it's 28000 feet above ground, to start with, then every passing minute "m" is dropping by 2000 feet, let's see,
1 minute.........................28000 - 2000(1)
2 minutes......................28000 - 2000(2)
3 minutes......................28000 - 2000(3)
4 minutes......................28000 - 2000(4)
m minutes.....................28000 - 2000(m)
h = 28000 - 2000m.
12+12+12 =36
but
10+12+14=36
10 could be the smallest consecutive even number
Because if x is greater than y, then x-y wouldn’t be below 0 like it’s shown, so x must be less than y.
And if x is less than y, any negative y would mean x is negative as well since it’s always less than y. And as shown, x+y is positive so it’s impossible for y to be negative.
Answer:
Volume: 2000 cm^3 Surface Area: 1360cm^2
Step-by-step explanation:
Ok, so we know the formula for volume is length x width x height, so we can substitute in the numbers given, so we end up with:
25 x 4 x 20
when we multiply them together, we get:
2000cm^3. That's the volume.
The formula for Surface Area is:
S.A.=2(lw+wh+lh) . Now we substitute in the numbers given
S.A.=2( (25 x 4)+(4 x 20)+(25 x 20)) . Then we add and multiply, so we get:
S.A. = 1360cm^2
The Surface Area is 1360cm^2.
Hope this helped, sorry if I was wrong somewhere!

Answer:
Step-by-step explanation:
y = 4.8x + C
53.8 = 4.8(4) + C
53.8 = 19.2 + C
C = 34.6
