Answer:

625 tiles

Step-by-step explanation:

According to the scenario, computation of the given data are as follows,

Total room floor area = 16 × 12 = 192

So, area of one third room = 192 × (1 ÷ 3)

Area of one third room = 64

Length of each tiles = 0.32

As it is a square tile, width = length, = 0.32

o, total area of each tile = 0.32 × 0.32 = 0.1024

So, number of tiles to cover 64 area of room = 64 ÷ 0.1024 = 625 tiles.

Hence, 625 tiles needed to cover one third of room.

I NEED HELP!!! ASAP!!!
omeli [17]

Answer:

A.

Step-by-step explanation:

In the picture, the estimated slope goes down, so it has to be negative, eliminating 2, B and D

It isn't a gradual line, as 6x is, so that is eliminated.

When we look at the estimated line, we can count out on the grid 3 to the right and 4 down, doing that a few times.  If you then connect the dots, it will be a line probably very close to your estimate.

Prove that 3 power p + 1 - 3 power P upon 2 multiply 3 power p is equal to 1 ​
Anit [1.1K]

Answer:

see explanation

Step-by-step explanation:

note that 3^{p+1} = 3^{p} × 3 ( when multiplying exponents are added )

Given

\frac{3^{p+1}-3^{p}  }{2.3^{p} } ← factor out 3^{p} on numerator

= \frac{3^{p}(3-1) }{2.3^{p} }

= \frac{2.3^{p} }{2.3^{p} }

= 1
