You need to add the surface areas up together

Answer:

Omar

Step-by-step explanation:

to find the base, which i am to assume they want to find the triangle base based on the formula they are using,

you should multiply base * height, then divide by 2, since it is a triangle, you not solving for a rectangle.

dividing by 2 and multiplying by 1/2 is the same thing!

so,

1/2 (7* 24) is the right answer to finding the base!

Kari looked at he direct base of 7*28, however, that shape is actually a rectangle... so Kari is wrong because he multiplied that dimension by 1/2, which is the formula for a triangle.

Omar is correct because he chose the dimensions of a triangle, and properly used the triangle formula!

i hope this helped you out!

stay safe!

Please help i put the pictures down low, I really need it.
SVEN [57.7K]
Part A
.. (480 books)/(5 cartons) = 480/5 books/carton = 96 books/carton

Part B
.. (7440 dollars)/(480 books) = 7440/480 dollars/book = $15.50 for 1 book

Part C
.. (2 minutes)/(48 books) * (200 books) = 400/48 minutes
.. = 8 minutes 20 seconds

Part D
In 9 minutes, the worker unpacked
.. (48 books)/(2 minutes)*(9 minutes) = 216 books
In 9 minutes, the manager upacked
.. (54 books)/(3 minutes)*(9 minutes) = 162 books

We note that 216 -162 = 54.

The worker unpacked 54 more books in 9 minutes than the manager did.

Line E passes through the points (2, 3) and (4, -3). What is the slope of a line perpendicular to line E?
lilavasa [31]
\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
%  (a,b)
&&(~ 2 &,& 3~) 
%  (c,d)
&&(~ 4 &,& -3~)
\end{array}
\\\\\\
% slope  = m
slope =  m\implies 
\cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-3-3}{4-2}\implies \cfrac{-6}{2}\implies \cfrac{-3}{1}

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus

\bf \textit{perpendicular, negative-reciprocal slope for}\quad \cfrac{-3}{1}\\\\
negative\implies  +\cfrac{3}{ 1}\qquad reciprocal\implies +\cfrac{ 1}{3}\implies \cfrac{1}{3}

A fair cube has 2 blue sides, 2 red sides, and 2 green sides.
natulia [17]
4/6 or 2/3. All you need to do is add the amount of blue and red sides from the cube and divide it by the total number of sides on a cube.

You can also say 66%

Hope this helps!! :)
