Answer:
B. 73°
Step-by-step explanation:
<em>m</em><em>L</em><em> </em>HLK = ½ × <em>mL</em><em> </em>HJK = ½×146=73°
To estimate the volume, you will use the formula for finding volume of a pyramid.
You will need to convert the height, given in feet, to yards.
(48 x 10)/3= 160 yards
You also need to convert the area of the base to square yards.
571536 ft.²/ 9 ft.² (1 square yd)= 63,504 yd.².
V = 1/3 BH, where B is the area of the base.
V = 1/3 x 63504 x 160
V = 3,386880 cubic yards
The approximate volume of The Great Pyramid is 3,386,880 yd.³.
D=dog's weight
c=cat's weight
d=7c
d+c=72
sub 7c for d
7c+c=72
8c=72
divide both sides by 8
c=9
d=7c
d=7(9)
d=63
dog=63lb
