Answer:

9.) 6.5 ft

10.) 36 ft²

11.) 770 cm²

12.) 10,087 cm³

Step-by-step explanation:

9.) Find the height:

V = lwh

234 = 8(4.5)h

234 = 36h

/36 /36

6.5 = h

10.) Area of base:

B = lw

B = 8(4.5)

B = 36

11.) Area of the base:

B = lw

B = 35(22)

B = 770

12.) Volume of the pyramid:

V = Bh/3

V = 770(39.3)/3

V = 30,261/3

V = 10,087

C= 44+(p-1)(32)/2 what is p?

Vilka [71]

Answer: $\bold{p=\dfrac{c-28}{16}}$

<u>Step-by-step explanation:</u>

$c=44+\dfrac{(p-1)(32)}{2}\\\\c=44+(p-1)(16)\quad \rightarrow\quad \text{simplified}\ (32\div2=16)\\\\c=44+16p-16\quad \rightarrow\quad \text{distributed 16 into p - 1}\\\\c=28+16p\quad \rightarrow\quad \text{added like terms (44 - 16)}\\\\c-28=16p\quad \rightarrow\quad \text{subtracted 28 from both sides}\\\\\dfrac{c-28}{16}=p\quad \rightarrow\quad \text{divided 16 from both sides}$
