False.
For the first part, 4(3 + 5) needs to be added first so its 4 * 8. This is 32 - 10.
The second part will have 4 * 3 which is 12 + 5 which is 17. Finally subtract 10 and its 7.
And 22 is not equal to 7
Resistances in series add algebraically.
Therefore the total resistance of R₁=150 Ω, R₂=60 Ω, and R₃=620 Ω is
R = R₁ + R₂ + R₃ = 150+60+620 = 830 Ω
Answer: 830 Ω
V=BA×h
A(triangle)=(4×3.5)/2=7cm²
V(prism)=7×10=70cm³
Hope this helped!
Answer:
24 cubic inches
Step-by-step explanation:
The formulas for the volume of a cylinder and cone are ...
volume of a cylinder = πr^2·h
volume of a cone = (1/3)πr^2·h
For the same radius and height, the cone has 1/3 the volume of the cylinder. Your cone's volume is ...
(1/3)·(72 cubic inches) = 24 cubic inches
Answer:
B.
