Answer: 2 2/3.
Explanation:
= -7/3 + 5
= 5x3/3 - 7/3
= 5x3-7/3
=8/3
And then I combined the fraction into a mixed fraction. So: 2 2/3. Hope it helped! :)
Divide it into one piece so 3.6 / 2 = 1.8 then times that by the number of pieces you want so 3.6 / 2 * 5 = 9
<span>The <u>correct answer</u> is:
576 sq. cm.
Explanation:
The surface area of a figure is the sum of the areas of the faces of the figure.
The slant height goes from the apex of the pyramid along a face and is perpendicular to the base at the bottom of that face. This gives us 2 measurements of each triangular face of the pyramid: the height (the slant height of the pyramid is the height of the triangular face), 18 cm, and the base <span>of the triangular face, 12 cm.
The formula for the area of a triangle is A = 1/2bh; using our measurements we have:
A = 1/2(12)(18) = 108 sq. cm.
There are 4 triangular faces on a square pyramid, and each will have an area of 108 sq. cm.; this gives us:
4(108) = 432 sq. cm.
The area of the base is given by length times width, or 12*12 = 144 sq. cm.
This gives us a total surface area of 432+144=576 sq. cm.</span></span>
