you were planning to use a ceramic tile design in your new bathroom. The towels are blue and white equilateral triangle of you d

Sonja [21]

I found the image that should have accompanied this problem.

Given:
equilateral triangle with sides that measures 7cm.
hexagonal shape meaning 6 sides or 6 equilateral triangles used.

Area of an equilateral triangle = √3/4 * a²
A = √3 /4 * (7cm)²
A = 1.73/4 * 49cm²
A = 21.20 cm²

21.20 cm² * 6 tiles = 127.20 cm² ARea of the hexagon.

Can someone please help me on this problem? I need help on it please!!

8_murik_8 [283]

Answer:

60 m/h

Step-by-step explanation:

1. the basic formula is Time=Distance/Speed;

2. total time is time1 (for 84 miles)+time2 (for 130 miles)=time (4 hours);

3. the time for the first 84 mi. is time1=84/S;

4. the time for the rest 130 mi. is time2=130/(S-10);

5. using all the data of items 2-4, it is possible to substitute into the basic formula and resolve an equation:

$\frac{84}{s} +\frac{130}{s-10} =4; \ => \ 2s^2-127s+420=0;$

$\left[\begin{array}{ccc}s=60\\s=3.5\end{array}$

note, that the value of speed has one condition: s>10. It means, the only value is true: 60 miles per hour.

An art project has an area of 63.6 square inches. What is the width, in inches, of the project?

Flura [38]

Answer:

The width of the art projects of area 63.6 square inches is 7.97 inches .

Step-by-step explanation:

Given as :

The area of the square art project = 63.6 square inches

Since The shape of the art project is square

So, The Area of square = A = side × side = side²

Now, let the measure of the width of art project = w inches

I.e side = w inches

or , A = side²

Or , A = w²

Or, 63.6 = w²

So, w = $\sqrt{63.6}$

I.e w = 7.97 inches

So, the width of the projects = w = 7.97 inches

Hence The width of the art projects of area 63.6 square inches is 7.97 inches . Answer
