For a regular n-agon with side length "s" and apothem "h", the area will be
.. A = n*(1/2)*s*h
Your area is
.. A = 10*(1/2)*(3.25 m)*(5 m) ≈ 81.3 m^2

Which statements are true about a rectangular pyramid with a height of 9 centimeters and a base with the dimensions of 4 centime

Semmy [17]

Answer:

B. The area of the base of the pyramid, B, is 24 centimeters squared.

C. A rectangular prism with the dimensions of 9 centimeters by 4 centimeters by 6 centimeters will have 3 times volume of this pyramid.

Step-by-step explanation:

Given a rectangular pyramid with:

Height=9 cm

Base Dimensions = 4 centimeters by 6 centimeters

Base Area B=4 X 6 =24 Square cm.

Therefore, Option B (The area of the base of the pyramid, B, is 24 centimeters squared) is correct.

Volume of a pyramid = $\frac{1}{3} $ X Base Area X Height$

$=\frac{1}{3} X 24X9=72 cm^3$

Volume of a Prism with the dimensions of 9 centimeters by 4 centimeters by 6 centimeters

=Base Area X Height

=24 X 9

$=216 cm^3$

Now, 216/72=3

Therefore, A rectangular prism with the same dimensions will have 3 times volume of this pyramid

Therefore, <u>Option C is correct.</u>

Determine the value of x in the equation x+5x=5x+7

12345 [234]

$\text{Hey there!}$

$\mathsf{Determine\ the\ value\ of\ x\ in\ the\ equation\ x+5x=5x+7.}$

$\mathsf{SIMPLIFY\ both\ sides\ of\ your\ equation}$

$\mathsf{x+5x=5x+7}$

$\mathsf{COMBINE\ your\ like\ terms}$

$\mathsf{(x+5x)=(5x+7)}$

$\mathsf{The\ RIGHT\ side\ DOES\ NOT\ have\ any\ like\ terms\ so\ we\ can}\\\mathsf{can\ leave\ alone}$

$\mathsf{x+5x= 6x}$

$\mathsf{Your\ new\ equation: 6x=5x+7}$

$\mathsf{SUBTRACT\ by\ 5x\ on\ your\ sides}$

$\mathsf{6x-5x}\\\mathsf{=}\\\mathsf{7-5x}$

$\mathsf{SOLVE\ your\ equation\ above\uparrow}$

$\mathsf{If\ you\ SOLVED\ correctly\ you\ SHOULD\ have\ the\ VALUE\ of\ x}$

$\boxed{\boxed{\mathsf{Thus\ your\ answer\ is\ x=7}}}\checkmark$

$\text{Good luck on your assignment and enjoy your day!}$
