Answer: 2080
Step-by-step explanation: formula for volume of trapezoid prism is bh. 10 times 19 is 190. formula for rectangular prism is lwh. 7 times 30 times 9 is 1890. add 190 and 1890 for both of their volumes.
Answer:
$573
Step-by-step explanation:
955* 0.60=573
or
10% of 955= 95.5
50% of 955=477.5
477.5=95.5=573
If you simply solve the equation for w, rather than "guess and check" using the values in the "replacement set," you find ...
... 6w +6 = 60 . . . . simplify the equation
... 6w = 54 . . . . . . . subtract 6
... w = 9 . . . . . . . . . divide by 6
The appropriate choice is ...
... D. 9
The surface area is A=4(pi)r. The equation for this would be A=4(pi)0.7, which is about 6.16 inches squared (of leather). The volume would be V=4/3(pi)r^3, which is about 1.44 inches cubed. Hope I helped! :-) (I tried :P)
