Answer:
255 seconds
Step-by-step explanation:
60 seconds x 1.30 = 78.78 seconds
78.78 seconds x 1.5 = 117 seconds
117+78+60= 255 seconds
hope this helps ^D^
The answer to this problem would be B. Here are the steps:
So, the dimensions of the prism are: 9,3, and 7.
Multiply them all: 9×3×7=189
Lastly: you multiply 189×1/3=63 yd^3
Incase you are wondering, since each cube is 1/3 in length you multiply that by the volume of the prism.
Hope this helps (:
Radius = sqrt(18) = 3*sqrt(2)
diameter = 2(3sqrt(2)) = 6sqrt(2)
i mean ig but 129.... ehh
