Answer:
3 2/5
I converted these into decimals, because I find it easier ^.^
We have an 8 feet board, and we twice remove 2 1/3 from that number.
8 - 2 1/3 = 5.7
5.7 - 2 1/3 = 3.4 or 3 2/5
~Hope this helps~
Answer:
33/338
Step-by-step explanation:
Green = 11
Red = 6
Blue = 9
P.Red = 6/26 = 3/13
P.Green = 11/26
P. Both in turns = 3/13 * 11/26
= 33/338
Step 1: Find the slope<span> of the </span>line<span>. To find the </span>slope<span> of the given </span>line<span> we need to get the </span>line<span> into </span>slope-intercept form<span> (</span>y<span> = mx + </span>b), which means we need to solve fory<span>: The </span>slope<span> of the </span>line<span> 3x – 5y = 9 is m = </span>3<span>/5. Therefore, the </span>slope<span> of the </span>line parallel<span> to this </span>line<span> would </span>have<span> to be m = </span>3<span>/5.

The pyramid given above has four faces. Each of which are in triangular shape. The area of the triangle is calculated through the equation,
A = bh / 2
where A is area, b is base and h is the height.
Substituting the known values,
A = (4 inch)(9 inch) / 2 = 18 in²
Multiplying this area by 4 will give us an answer of 72 in².
Then, we also calculate for the area of the square base.
A = s²
where s is the measure of each side of the square.
A = (4 in)² = 16 in²
Finally, we add up the calculated areas.
surface area = 72 in² + 16 in²
<em>surface area = 88 in²</em>
Hence, the surface area of the figure is equal to 88 in².
