Answer: 22 tiles

Step-by-step explanation: well if the tiles are 1/4 of a foot then you need 4 of them to equal a foot. since the measurement's are 5.5ft, multiple 5x4 to get 20. then add two more for the .5 (2 i/4 equal 1/2) so you get 22 tiles.

Solve for a. Please help!
Marizza181 [45]

Answer:

a = 7

Step-by-step explanation:

This is a special trig triangles. Special trig triangles are identified by their angle measures and their sides have a unique relationship. This is a 30 - 60 - 90 triangle which has sides 1 - √3 - 2 or multiples of this. This means all 30 - 60 - 90 triangles have side lengths with the pattern 1 - √3 - 2. Here the triangle has a - 7√√3 - 14. The value of a is 7 since 7*√3 = 7√3 and 2*7 = 14.

Answer:

5\sqrt{8}

24\sqrt{3}

Step-by-step explanation:

To simplify the square roots, break the number under the square root into factors. Any factors which are perfect squares may be simplified to outside the square root.

\sqrt{200}=\sqrt{25*8}  =\sqrt{25}*\sqrt{8}= 5*\sqrt{8}   =5\sqrt{8}

and

4\sqrt{108}=4\sqrt{27*4}  =4*\sqrt{27}*\sqrt{4}=4* \sqrt{9} *\sqrt{4}*\sqrt{3}    =4*3*2*\sqrt{3}=24\sqrt{3}

Let f(x)=x^3 and g(x)= √x, and h(x)=x/3. Find each of the following: f(g(h(6)))
rewona [7]

Answer:

go from inside out.

h(x)=x/3

(\sqrt{2})^{3}=> h(6) = 6/3 = 2

g(x) = \sqrt{x}

=> g(h(6)) = g(2) = \sqrt{2}

f(x) = x^{3}

=> f(g(h(6))) = f(\sqrt{2} ) = (\sqrt{2} )^{3}
