Answer: 63/100 and 0.63

Step-by-step explanation: To find the fraction and decimal that is represented by this model, we first need to count how many cubes are shaded in. In the diagram shown, 63 of the cubes are shaded in and there is 100 of the cubes in total. the fraction 63/100 cannot be reduced so that is our answer. Now, let's turn 63/100 into a decimal. To write 63/100 as a decimal, remember that the bar that separates the numerator and denominator of the fraction is a division bar in disguise. This means that we can divided 63 by 100 and we will get 0.63 which is the equivalent decimal.

Answer:

Cube=150cm^2

Triangular Prism=228ft^2

Step-by-step explanation:

Cube

$A=6a^2=6*5^2=150cm^2$

Triangular prism

Using these formulas

$A=2A_{B}+(a+b+c)h\\A_{B} =\sqrt{s(s*a)(s*b)(s*c)} \\s=\frac{a+b+c}{2}$

Solving for A

$A=ah+bh+ch+\frac{1}{2} \sqrt{-a^4+2(ab)^2+2(ac)^2-b^4+2(bc)^2-c^4} \\=6.5*11+5*11+6.5*11+\frac{1}{2} *\sqrt{-6.5^4+2*(6.5*5)^2+2*(6.5*6.5)^2-5^4+2*(5*6.5)^2-6.5^4} \\=228ft^2$

What is 2 times 5 to the 3rd power divided by (9-4) raised to the power of 4

Maslowich

Heyo Kiddo. How are you doing today?

Let's figure this out.

So in number form, the equation will be looking a little like this:

$2(5) ^{3} / (9-4)^4$

To solve.

$2(5) ^{3} / (9-4)^4 \ \textless \ Parenthesis first\ \textgreater \ 

2(5)^{3} / 5^4 \ \textless \ Exponents\ \textgreater \ 

2(125) / 625 (Multiply)

250 / 625 (Divide)

0.4 (Answer)$

So I hope this answers your question and that you have a great day. :)
