Answer:
220.5 in³
Step-by-step explanation:
<u>Volume = L×W×H</u>
Volume = 10.5 in × 7 in × 3 in
Volume = 220.5 in³
By Pythagoras AB^2 = 12^2 - 6^2 = 108
AB = sqrt 108 = 10.39 to nearest hundredth
The perpendicular from M to DC will be parallel and equal to AB so it = 10.39.
Also AB^2 = CB * DB
108 = 6 * DB
DB = 108/6 = 18
so DC = 18-6 = 12
MD^2 = (1/2*12)^2 + 108 = 144
so MD = 12
Answer:
Y=2x+2
Step-by-step explanation:
Y=0.5x-1
To find inverse, switch and y
x=0.5y-1
0.5y=x+1
Y=2x+2
He switched the 5 and 6 into different places
I think the answer would be 32 degrees
