Answer:
=0.3 per km²
Step-by-step explanation:
Population density is the population per uni area.
Area=πr² Where A is area and r is the radius of the circle.
A=3.14×34
=106.76km²
Population density = Population/Area
=32 antelopes/106.76 km²
=0.3 per km²
The population of antelopes within the given radius is 0.3 per km²
Answer:
a. 2x -3
b. 7
Step-by-step explanation:
a. The expression that represents the difference is sales between the two sales will be:
9x - (7x + 3) = 9x - 7x - 3 = 2x - 3
b. What we do here is to simply substitute the value of 5 for x
mathematically, we have to substitute the value of 5 in the expression above
We have this as:
2(5) -3
= 10-3 = 7
Answer:
Monthly Living Expense = 2375
Monthly Fixed Expense = 1975
Step-by-step explanation:
Let monthly living expense be "x"
and monthly fixed expense be "y"
<u>"monthly living expenses were 400 more than his monthly fixed expenses":</u>
x = 400 + y
<u>"Richard total monthly expenses were 4350":</u>
x + y = 4350
Putting Equation 1 in Equation 2:
(400 + y) + y = 4350
400 + 2y = 4350
2y = 3950
y = 1975
Now, x = 400 + y = 400 + 1975 = 2375
Answer:
65°
Step-by-step explanation:
A triangle always will ad up to 180°. Therefore, if you subtract 130° from 180° you'll probably get 50° but that's the closest one to it.
Hope this helps :)
