Answer:
Step-by-step explanation:
Rewrite 2x-5y< 15 as follows: Add 5y to both sides. Then 2x < 15 + 5y.
Next, subtract 15 from both sides: 2x - 15 < 5y.
Finally, divide all terms by 5: (2/5)x - 3 < y
Now find the y-intercept of this line. Let x = 0. Then y = -3. Plot (0, -3) on graph paper. Now, starting at (0, -3), move your pencil point 5 spaces to the right and 2 spaces up. Plot this new point, (5, -1). Now draw a dashed line through both (0, -3) and (5, -1). Shade the area ABOVE this dashed line.
Area of the middle rectangular section = length x width = 35 x 20 = 700 square cm.
The radius of the circular sections is 25 cm
Area of a full circle is pi x r^2 = 3.14 x 25^2 = 1962.5 square cm.
There are two quarter circles which is 1/2 of a circle. The area of those would be 1962.5/2 = 981.25 square cm.
Total area of the figure = 700 + 981.25 = 1681.25 square cm
Answer:
Each zoo covers 95 acres.
Step-by-step explanation:
Given data:
Ranch covers = 825,000 acres
Zoo fitted inside the ranch = 8,684
Leftover acres = 20
Acres covered by each zoo = ?
Solution:
Let's suppose that the acres covered by each zoo is donated by a symbol "A"
According to the given condition, we develop a mathematical equation as follow:
8,684 A + 20 = 825,000
8,684 A = 825,000 - 20
8,684 A = 824,980
A = 824,980 / 8,684
A = 95
So, the acres covered by each zoo is 95.
