A rectangular park is 50m long and 35m broad.A 3.5m broad pavement runs along the boundary of the park .Find the cost of cementi
2 answers:
Solution:
<u>Step-1: Find the area of the park.</u>
- 50 x 35 = Area of park
- => 1750 m² = Area of park
<u>Step-2: Find the area of the inside rectangle.</u>
- (50 - 7)(35 - 7) = Area of inner park
- 43 x 28 = Area of inner park
- 1204 m² = Area of inner park
<u>Step-3: Subtract the area of the inner park from the area of the park.</u>
- 1750 - 1204 = Area of pavement
- => 546 m² = Area of pavement
<u>Step-4: Find the cost per square.</u>
- $400 = 8 m²
- => 1 m² = $50
<u>Step-5: Multiply 546 and 50 to find the cost.</u>
- 546 x 50 = Cost of pavement
- => $27300 = Cost of pavement

Answer:
The line equation in slope-intercept form is:
Hence, option D is true.
Step-by-step explanation:
Given the points
- (0, 4)
- (5, 2)
Finding the slope between the points
As the y-intercept is obtained by setting the value x = 0.
As we know that when x = 0, the vale of y-intercept y = 4
so the y-intercept is b = 4.
As the slope-intercept form is
substituting the slope m = -2/5 and the y-intercept b=4
Therefore, the line equation in slope-intercept form is:
Hence, option D is true.
Answer:
units I THINK
Step-by-step explanation:
using the distance formula, -2 - 1 = -3
-3 x -3 = 9
-5 - 4 = -9 x -9 = 81
81 + 9 = 90
sqrt 90 simplified is .
so im pretty sure that's the answer.
