Width of the actual barrier = 1.2 miles
Width of the barrier in the blueprint = 2 inches
2 inch dimension of blueprint = 1.2 miles of original
So, 1 inch dimension of blueprint = 1.2/2 = 0.6 miles.
Since the length of the barrier in the blueprint = 9 inches,
length of the actual barrier = 9(0.6) = 5.4 miles.
Answer:
729 * 10^-45
Step-by-step explanation:
Here, we want to expand the value based on the exponent
We have the power multiplying every term in the bracket
That would be;
9^3•10^-45
= 729 * 10^-45
x = -14, y = -6
x = ?, y = -4
We can cross multiply
-14/ -6 = ?/ -4
First, -4 x -14 = 56
Then 56/ -6 = -9.3
so if x= -14 and y= -6 then x= -9.3 when y = -4
