Answer:
Step-by-step explanation:
First, lets simplify everything in the parenthesis.
(3×10^2 )×(2×10^−4 )=
In the parenthesis, since exponents come before multiplication in the order of operations, we need to do the exponents first.
(3 • 100) • (2 • 1/10^4)
Now, we can just multiply everything from left to right to get:
6*10^-2
Or
.06

Answer:
Length is 26, width is 7
Step-by-step explanation:
Supposing y= width and x= length
We know from the question that
y= 1/2x -1
And the perimeter of any rectangle is 2y + 2x
Substitute y for 1/2x-1
2(1/2x-1) + 2x = 46
x - 2 + 2x = 46
3x = 48
x= 16
y= (1/2*16)-1
y=7
