Answer:
Surface area of cubic box = 376 square inch
Step-by-step explanation:
Given:
Using net diagram
Length of cubic box = 10 inches
Width of cubic box = 6 inches
Height of cubic box = 8 inches
Find:
Surface area of cubic box
Computation:
Surface area of cuboid = 2[(lb) + (bh) + (hl)]
Surface area of cubic box = 2[(10)(6) + (6)(8) + (8)(10)]
Surface area of cubic box = 2[60 + 48 + 80]
Surface area of cubic box = 2[188]
Surface area of cubic box = 376 square inch
Answer:
<h3>A. about 3.4 seconds</h3>
Step-by-step explanation:
Given the volume of air in liters in the human lungs described by the function V(t) = 0.173t +0.15t^2 - 0.035t^3 where t is the time in seconds,
The beginning of this respiratory cycle for the lungs to fill to their maximum volume of air occurs when dV/dt = 0
dV/dt = 0.173 + 0.3t - 3(0.035)t²
dV/dt = 0.173 + 0.3t - 0.105t²
Since dV/dt = 0
0.173 + 0.3t - 0.105t² = 0
multiply through by -1
-0.173 - 0.3t + 0.105t² = 0
0.105t² -0.3t-0.173 = 0
Factorize;
t = 0.3±√0.3²+4(0.105(0.173))/2(0.105)
t = 0.3±√0.09+0.07266/0.21
t = 0.3±√0.16266/0.21
t = 0.30±0.4033/0.21
t = 0.7033/0.21
t = 3.349secs
t ≈ 3.4secs
Hence it will take about 3.4secs for the lungs to fill to their maximum volume of air
I think its option A as u cant answer the other 2, we don't know the chances of getting heads or tails we can only see how many of which we can get in total which is 2 as we can only get an outcome of heads or tails

Answer:
q = 768
Step-by-step explanation:
The proportionality relation is given as ...
q = k(√h)/j³
Then ...
k = q·j³/√h = 24·2³/√16 = 48
For the given values, q is ...
q = 48·(√4)/(1/2)³ = 48·2·8
q = 768
Answer:
FALSE. The correct answer is y = - 30.
Explanation:
3*(30+8) = 2(30)-6
3*38 = 60-6
114 = 54
<em><u>The correct answer is y = -30.</u></em> (Negative 30)
3*(-30+8) = 2(-30)-6
-66 = -66
