Hey there!
To turn a fraction into a decimal, simply divide the numerator by the denominator.
so,
= 0.16
So, the decimal form of is 0.16.

For part A, use the Pythagorean Theorem.
a.) Since we see that the triangle is made up of two right triangles, simply subtract half the leg from the length of the hypotenuse.
10/2 = 5
13² - 5² = 169 - 25 = √144 = 12 centimeters cubed for the height.
b.) For this, we need to find the surface area of the prism. The surface area of a triangular prism can be found using the formula:
Surface area (SA) = 10(12) + (10 + 13 + 13)(20)
=120 + 660 = 780 cm²
The slope is 1/2 and doesn’t need to be simplified
I'm confused can you edit your question and then ask it again
