A distrubutor shipped 3/4 of a cheese order that was to be distributed equally between 3 pizza restaurants. What fractional part
romanna [79]
Let's say there are 12 boxes of cheese in the original order. Draw a table with 4 rows and 3 columns. Shade exactly 3 of the rows (the entire row). So you should shade in 9 boxes total with 3 left unshaded.

Those 9 shaded boxes are then distributed equally among the 3 restaurants. So each restaurant gets 9/3 = 3 boxes

Comparing those 3 boxes to the original 12 forms the fraction: 3/12 = 1/4

So each restaurant gets 1/4 of the original order

Answer: 1/4

Note: another way to do this is to multiply 1/3 by 3/4 to get 1/4

What is the perimeter of khgj?
kaheart [24]

Answer:

  58 in

Step-by-step explanation:

The fact that the rectangles are congruent means both have a length of 18 in and a width of 11 in. The perimeter is ...

  P = 2(L +W)

  P = 2(18 in + 11 in) = 2(29 in)

  P = 58 in

The perimeter of KHGJ is 58 inches.

The surface are I cannot find
Ilia_Sergeevich [38]

check the picture below.


so the triangular prism is really just 3 rectangles and 2 right-triangles,

now, we know the base of one of the triangles is 2.6, what's its height?

since it's a right-triangle, we can simply use the pythagorean theorem to get "h".


\bf \textit{using the pythagorean theorem}&#10;\\\\&#10;c^2=a^2+b^2\implies \sqrt{c^2-a^2}=b&#10;\qquad&#10;\begin{cases}&#10;c=\stackrel{hypotenuse}{5.2}\\&#10;a=\stackrel{adjacent}{2.6}\\&#10;b=\stackrel{opposite}{h}\\&#10;\end{cases}&#10;\\\\\\&#10;\sqrt{5.2^2-2.6^2}=h\implies 4.5\approx h


so, we can now, simply get the area of both of the triangles and the three rectangles and sum them up, and that's the area of the triangular prism.


\bf \stackrel{two~triangles}{2\left[ \cfrac{1}{2}(2.6)(4.5) \right]}~~+~~\stackrel{rectangle}{(2.6\cdot 4.3)}~~+~~\stackrel{rectangle}{(4.3\cdot 3.9)}~~+~~\stackrel{rectangle}{(4.3\cdot 5.2)}&#10;\\\\\\&#10;11.7+11.18+22.36\implies \blacktriangleright 45.24 \blacktriangleleft
