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.

Question 8b , thanks
marta [7]

Answer:

Step-by-step explanation:

a = \frac{2b+1}{3b-1}

b = 2/3

2b + 1 = 2*\frac{2}{3}+1\\\\=\frac{4}{3}+1\\\\=\frac{4}{3}+\frac{3}{3}\\\\=\frac{7}{3}\\\\3b-1 = 3*\frac{2}{3}-1\\\\=2- 1 = 1\\\\\\

a = \frac{2b+1}{3b-1}\\\\a=\frac{\frac{7}{3}}{1}\\\\=\frac{7}{3}\\\\

a = 7/3

b)

\frac{2b+1}{3b-1}=a\\\\

Cross multiply,

2b + 1 = a*(3b - 1)

2b + 1 = a*3b - 3*a

2b + 1 = 3ab- 3a

2b = 3ab - 3a - 1

2b - 3ab = -3a  - 1

b(2 - 3a) = -3a - 1

b =\frac{-3a - 1}{2 - 3a}

Triangle ABC , m∠A=45° and c = 16, find b.
zmey [24]

Using the cosine function:

\begin{gathered} \cos (\theta)=\frac{_{\text{ }}adjacent}{_{\text{ }}hypotenuse} \\ so\colon \\ \cos (45)=\frac{b}{16} \end{gathered}

Solve for b:

\begin{gathered} b=16\cdot\cos (45) \\ b=8\sqrt[]{2} \end{gathered}

Answer:

Graph C with the green dots.

Step-by-step explanation:

y = 0.5x + 5 is a linear equation, so we can rule out A because it is not straight.

5 represents the y-intercept, so we rule out B because that graph doesn't intercept the y-axis at (0,5).

Graph C represents a straight line that passes through (0, 5) & has a 0.5 slope, so that is our answer.

Hope this helps. :0)
