Step-by-step explanation:
multyply both like 10 x 6 then 11 x 7 after that subtrac the numbers that you múltiple and you will get the answer
A--width b--length b=864 Divided by a b=3a divided by 2 864 divided by a = 3a divided by 2 a =24 b=864 divided by 24 = 36 Answer= the length of the basement is 36 feet
Answer:
Answer with explanation and steps are in the following attachment.
Step-by-step explanation:
For prisms: V = Bh where B is the area of the Base of the prism and h is the height of the prism.
B = 12(20)
B = 240
Now let's substitute into:
V = Bh
4800 = 240h divide both sides by 240
20 = h
So the height of the prism is 20 cm
Answer:
∠BCD = 34°
Step-by-step explanation:
∠FCE + ∠FCA + ∠ACB = 180° ( straight angle ), thus
∠FCE + 90 + 56 = 180, that is
∠FCE + 146 = 180 ( subtract 146 from both sides )
∠FCE = 34°, hence
∠BCD = ∠FCE = 34° ( vertical angles )
