(01.02 LC)Simplify negative 3 and 1 over 9 − negative 8 and 1 over 3.

blsea [12.9K]

As we are given with

$-3\frac{1}{9}-(-8\frac{1}{3})\\\\$

we are supposed to simplify this expression. which can be done as below

$\\=-3\frac{1}{9}+8\frac{1}{3}\\\\=\frac{-28}{9}+\frac{25}{3}\\\\=\frac{-28+75}{9}\\\\=-\frac{47}{9}\\$

$=5\frac{2}{9}$

A soundproofing tile is made of 8 identical solid right pyramids with square bases. The length of the whole tile shown is x inch

mylen [45]

Answer:

Option B ⇒ Area of base of each pyramid :

$(\frac{x}{4})^2 in^2$

Option A ⇒ Volume of pyramid :

$\frac{1}{3} x^{2} \cdot y$ cm3

Step-by-step explanation:

One side of tile consists of 4 pyramids and since length of whole tile is x,

So, the base length of each pyramid = $\frac{x}{4}$

⇒ Area of base of each pyramid = side²

⇒ Area =

$(\frac{x}{4})^2 in^2$

Volume of square based pyramid :

$=(Area of base )\cdot \frac{h}{3}\\=\frac{x^2}{3} cm^3$

For 1. The correct Option is B

For 2. The correct option is A
