Step-by-step explanation:
56 + (-56) is the same as 56 - 56 which equals zero
27/50 is a proper fraction because the numerator is less than the denominator.
Answer:
x = 18
Step-by-step explanation:
To write a proportion, we need to write down the data we have.
Shorter side of rectangle 1 = 6
Longer side of rectangle 1 = 13
Shorter side of rectangle 2 = x
Longer side of rectangle 2 = 39.
A proportion representing this would be:
Solving this proportion for x, we would have:
Therefore, the shorter side of the second rectangle is 18.
Answer:
t = 1.47 s
Step-by-step explanation:
y(x,t) = 0.6 sin (8 x – 24 t )
compare it with
y = A sin (k x - ω t)
now, A = 0.6
k = 8
ω = 24 rad/s
we know ω = 2πf
we know that
time taken
t = distance/time
= 4.4 / 3
t = 1.47 s
72
Explanation:
Volume of cuboid = 2 x 4 x 6 = 48 in3
Volume of pyramid = 1/3 x (4 x 6) x 3 = 24 in3
Total volume = 48 + 24 = 72 in3
