A = 1/2bh = 1/2(5)(12)
A = 60/2 = 30
answer
30 in^2
The correct answer is D) $336.
1. First calculate how much he spent on rental fees: $70 x 4 = $280
2. Next calculate how much he gave as a tip: $280 x 0.2 = 56
3. Add the two together $280 + $56 = $336
Muchas luck on your HW!
The number of feet of fencing that is needed to go around the pool path is D. 201 ft.
<h3>
How to calculate the number of feet?</h3>
We have a pool with a radius of 28 feet. The radius of the outer edge of the pool path would be equal to the radius of the pool plus the width of the path.
= (28 + 4) feet
= 32 feet
The circumference of the outer edge of the pool path would be equal to the perimeter.
p = 2 * pi * r
p = 2 * 3.14 * 32
p = 200.96 feet
p = 201 feet

Given:
End points a line segment are (9,-8) and (-1,-4).
To find:
The equation of perpendicular bisector of given line.
Solution:
Slope of given line is





Product of slopes of two perpendicular line is -1.



So, slope of perpendicular bisector is
.
Perpendicular bisector passes through the midpoint of given endpoints.




So, perpendicular bisector passes through (4,-6) and having slope
. The equation of perpendicular bisector is

where, m is slope.





Therefore, the equation of perpendicular bisector is
.
