Answer:
V = 240 
Step-by-step explanation:
To find the volume of a rectangular prism use this equation:
V = l*w*h
l = length (20 cm)
w = width (4 cm)
h = height (3 cm)
Plug all these values into the equation and solve:
V = (20 cm)(4 cm)(3 cm)
V = (80 
)(3 cm)
V = 240
Therefore, the volume of the rectangular prism is 240 .
I hope this helps! Good luck!
Answer:
17.4
Step-by-step explanation:
add it
38 mm to m
38 mm * (0.001 m / 1 mm)
**cancel mm units**
38 * (0.001 m / 1)
0.038 m
you're correct

- sin∅ = opposite over hypotenuse
Step-by-step explanation:
<u>Step 1: Define variables</u>
∅ = 39°
opposite leg = 9
hypotenuse = x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute: sin39° = 9/x
- Multiply <em>x</em> on both sides: xsin39° = 9
- Isolate <em>x</em>: x = 9/sin39°
- Evaluate: x = 14.3011
- Round: x ≈ 14.30
-5 Subtract 8 from -12 and divide -20 by 4 and get -5
