Since the base is a regular quadrilateral, each of its 4 sides must have length
s = P/4
s = (60 cm)/4 = 15 cm
The area of one lateral face is the product of side length and height.
A = s×h
105 cm² = (15 cm)×h
Then the height of the prism is
h = (105 cm²)/(15 cm) = 7 cm
The area of the base is then
B = s²
B = (15 cm)² = 225 cm²
The volume of the prism is the product of its base area and height.
V = Bh
V = (225 cm²)×(7 cm) = 1575 cm³
The volume is 1575 cm³.
7/13 = about 0.54
-1 1/2 = -1.5
The answer is
-1.7, -1 1/2, 0.04, 0.1, 7/13
You might know this property of parallelogram that "<span>Consecutive angles are supplementary" i.e A + D = 180. So 6x + 20 + 4x + 10 = 180. 10x = 150. x= 15. Therefore </span>∠A = 6x + 20 = 6( 15) + 20 = 110°. so option C is correct.

He has $170 minus the $25.50 fee= $144.50 left. If each session is $10.50, then divide 144.50 by $10.50 and you get 13.76. He will have enough for 13 help sessions
