9.252.063 rounded to the nearest hundredth is 9.252.060
Answer: Ok so first 0.05(6000 - x) + 0.07x = 372
300 - 0.05x + 0.07x = 372
300 + 0.02x = 372
0.02x = 72
x = 3600
He invested $3600 at 7% and $2400 at 5%.

Step-by-step explanation:
Answer:
F = 25
Step-by-step explanation:
Euler's formula for polyhedra states that
F + V - E = 2
Here V = 11, E = 34, thus
F + 11 - 34 = 2
F - 23 = 2 ( add 23 to both sides )
F = 25
We can write a proportion between short and long legs:

Solving for k yields
