Answer: There are 944 lots the broker will realize from this subdivision.
Step-by-step explanation:
Since we have given that
For 10 acre tract,
Number of lots = 50 by 100 foot = 5000
If the tract has 85600 square feet, we need to find the number of lots.
Since 1 acre = 43560 square feet
so, 10 acres =
square feet
Since there is direct variation, so it becomes,
![\dfrac{453600}{5000}=\dfrac{85600}{x}\\\\90.72=\dfrac{85600}{x}\\\\x=\dfrac{85600}{90.72}\\\\x=943.56\\\\x\approx 944](https://tex.z-dn.net/?f=%5Cdfrac%7B453600%7D%7B5000%7D%3D%5Cdfrac%7B85600%7D%7Bx%7D%5C%5C%5C%5C90.72%3D%5Cdfrac%7B85600%7D%7Bx%7D%5C%5C%5C%5Cx%3D%5Cdfrac%7B85600%7D%7B90.72%7D%5C%5C%5C%5Cx%3D943.56%5C%5C%5C%5Cx%5Capprox%20944)
Hence, there are 944 lots the broker will realize from this subdivision.
Answer:
16,500,000 people
Step-by-step explanation:
If South Africa has a population of 55,000,000 people, and the current spread of the virus may lead to 30% of death, this means that 30% of 55,000,000 people will die. 30% is similar to 30 cents per 1 dollar/100 cents. So this can be represented as 30/100. 30/100 x 55,000,000 = 16,500,000 people.
