Answer:

The temperature at 1,000 feet will be 56.4ºF; at 2,000 feet it will be 52.8ºF; and at 3,000 feet it will be 49.2ºF.

Step-by-step explanation:

Given that W. Altus is climbing 3,000 feet to the top of a mountain, starting at a temperature of 60ºF, which decreases 3.6ºF every 1,000 feet of elevation, to determine the temperature every 1,000 feet of elevation, the following calculations must be performed:

0 feet = 60ºF

1,000 feet = 60ºF - 3.6ºF = 56.4ºF

2,000 feet = 56.4ºF - 3.6ºF = 52.8ºF

3,000 feet = 52.8ºF - 3.6ºF = 49.2ºF

Thus, the temperature at 1,000 feet will be 56.4ºF; at 2,000 feet it will be 52.8ºF; and at 3,000 feet it will be 49.2ºF.

Kenisha uses the Fermi process to estimate the number of dollar bills that would cover her driveway. Her driveway is rectangular

shepuryov [24]

Answer:

option A

9×10^4/2×10^2

Step-by-step explanation:

Given in the question,

length of dollar bill = 6

width of dollar bill = 3

area of dollar bill = L x W

= 6 x 3

= 18inches²

length of driveway = 30

width of driveway = 20

area of driveway = L x W

= 30 x 20

= 600 ft²

1 ft² = 144 inches²

600 ft² = 86400 inches²

Number of dollar bills that would cover Kenisha driveway = 86400 / 18

Which can also be written as

86400 = 9 x 10 $^{4}$

18 = 2 x 10²

$\frac{9x10^{4} }{2x10^{2} }$
