The lot costs 5000 dollars.
<u>Step-by-step explanation:</u>
The cost of a House and the lot = $40,000.
Let us assume the cost of lot as 'x'
Given that, The cost of the house is 7 times as much as the lot.
Therefore, The cost of the house= 7x
The cost of both the house and the lot= x + 7x
$40,000 = x + 7x
40,000 = 8x
x = 40,000/8
x = 5,000
The lot costs $5000.
Answer:
The distance from sea level in mm is 0.5494 mm.
Step-by-step explanation:
Consider the provided information.
It is given that Our scale is that 100 mm on the map is equal to 6371 km in Earth.
This can be written as:
100 mm = 6371 km
Divide both the sides by 6371.
100/6371 mm = 1 km
We need to find the distance from sea level in mm, if the distance is 35 km.
Multiply both sides by 35.
100/6371 × 35 mm = 1 × 35 km
0.5494 mm = 35 km
Hence, the distance from sea level in mm is 0.5494 mm.
Kx+9=7
Kx=-2 (subtract 9 from both sides)
X=-2/k (divide k from both sides.
