Answer:
480 m²
Step-by-step explanation:
A = bh/2
A = 64 m × 15 m / 2
A = 480 m²
Divide botoh sides by 7
x-12=-3
add 12 to both sides
x+12-12=12-3
x+0=9
x=9
Answer:

Step-by-step explanation:
Given data
P= 45,000

Recall the expression for the compound interest

Since we are talking of depreciation

Substitute

Hence the exponential function is

The land bridge (Bering strait) and the crossing from Canada
Answer:
9 : 1
Step-by-step explanation:
given a linear ratio = a : b, then the corresponding area ratio is
a² : b²
Here the linear ratio of their edges = 3 : 1, hence
ratio of surface areas = 3² : 1² = 9 : 1
