Sara baked 3 dozen cookies. her brother ate 25 percent of them. sara took 1/3 of the remaining cookies to her neighbor and then ate 4 cookies herself. how many cookies were left

3 dozen cookies = 36 cookies

Brother ate 0.25(36) or 9 cookies.

36 - 9 = 27 cookies remain.

Sara took (1/3)(27) or 9 cookies went to her neighbor.

There are now 18 cookies of which Sara ate 4.

So, 18 - 4 = 14.

There are 14 cookies left.

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
