3 is incorrect, should be 28.9

16^2 + 18^2 = EG^2
256 + 324
580 = EG^2
EG ≈ 24.08

16^2 + 24.08^2 = AG^2
256 + 580 = AG^2
836 = AG^2
AG ≈ 28.9

5 is incorrect:

The base is 8.
Draw an altitude the base.
Since the triangle is isoceles, it divides the base in half.
Half of that base is 4.
Two right triangles have been formed with one leg 4 and hypotenuse 8.
4^2 + b^2 = 8^2
16 + b^2 = 64
b^2 = 48
b ≈ 6.93

The height of the triangle is 6.93, the base is 8.
A = bh/2 = 8*6.93/2 ≈ 27.7 ≈ 28

Change the fraction 7/12 to a decimal. Round your answer to the nearest thousandth
alina1380 [7]
Just divide.

\sf\dfrac{7}{12}\rightarrow7\div12\rightarrow0.58\overline{3}

0.583333. . .
      ^ This is the thousandths place

Look at the number after that, if it's 5 or more we round up, if it's 4 or less we round down.

It's 3, so we round down to 0.583.
