Answer:
x = 2.5
Step-by-step explanation:
4( x + 7) = 38
step 1 distribute the 4 to the x and 7
4 * x = 4x
4 * 7 = 28
we now have 4x + 28 = 38
step 2 subtract 28 from each side
28 - 28 cancels out
38 - 28 = 10
we now have 4x = 10
step 3 divide each side by 4
4x / 4 = x
10 / 4 = 2.5
we're left with x = 2.5
Let x be the resistance of the wire with the larger diameter.
x = (0.456 x (0.01)^2)/(0.0401)^2 = 0.0284 ohms
The answer is 0.0284 ohms.

Answer:
Option d. 75 times.
Step-by-step explanation:
Side length of a square pyramid of Pyramid A = 9 inches
height of pyramid A = 4 inches
where,
a = sides, h = height
= 27 × 4
= 108 inches³
and the volume of pyramid B = 8100
Now we will divide volume of pyramid B by the volume of pyramid A
= 75
Therefore, the volume of pyramid B is 75 times bigger than pyramid A.
Option d is the answer.
