Answer:
300 Square feet
Step-by-step explanation:
Susan built a rectangular fence around her swimming pool.
Length=15ft
Width(or Breadth)=10ft
Height=6ft
To solve this, picture a cuboid with the top and bottom open, that is the key to finding the Surface Area of the Fence.
Surface Area of a Cuboid= 2(LW+LH+WH)
However since the top and bottom are open, the Surface Area becomes
Surface Area of the fence= 2(LW+WH)
=2((15X6)+(10X6)
=2(90+60)=2 X 150 =300
Susan uses 300 Square feet to build her fence.
Answer:
pi
Step-by-step explanation:
To convert from degrees to radians, we multiply by pi/180
180 * pi/180 = pi
Multiply 3x and -2 by 3 and add 5 to right side of equal sign to get y = -1
Answer: B. A coordinate plane with points in quadrants II and IV.
Step-by-step explanation:
Let's take the point (-1,1) as an example
The point itself is in the second quadrant
the opposite of the point is (1,-1)
This point is in the fourth quadrant
Wouldn’t it be 0 cause 3-3 is 0 and 0 times anything is 0
