Answer:
76,800
Step-by-step explanation:
Given the following :
Length = 20 kilometers
Width = 12 kilometers
Population density = 320 people per sq km
Population =?
Recall:
Area of rectangle = Length × width
Therefore,
Area of Rectangleville = 20 km × 12 km = 240km^2
Population is related to population density and Area by the formula ;
Population density = population ÷ Area
Therefore,
Population = population density × Area
Population = 320 × 240 = 76,800
Therefore, the population of Rectangleville is 76,800 people
<h2>
Answer:</h2>
- 9 3 x 7 5
<h2>
Step-by-step explanation:</h2>
To get the combination that would yield the greatest result if the true number are multiplied,
<em>i. multiply each given combination</em>
73 x 95 = 6935
79 x 53 = 4187
97 x 35 = 3395
93 x 75 = 6975
<em>ii. get the largest result from the results calculated above in (i)</em>
The greatest of the results is 6975, therefore the digits should be placed like so;
<u> 9 </u> <u> 3 </u>
<u> 7 </u> <u> 5 </u>

<u />
39. 8 -0.7 are multiplied together so the answer is
(-0.7)^8
= 0.05765 to nearest 100 thousandth. ( using a calculator).
40. 10^4 + 0^12 = 10,000 + 0
= 10,000
The slope is 5/7
4-(-1)=5 which is the Y value
5-(-2)=7 which is the X value
Slope =Y/X
16 / 2 = 8
8 - 1 = 7
4 x 7 = 28
Hope this helps :)
