sara has a recipe for a cake that her mother gave her. the recipe calls for 3/4 cups of sugar for each cake. sara and her friend
aniked [119]

Sara is wrong because making 3 cakes instead of 1 would require 2 1/4 cups of sugar. The original 3/4 cups of sugar would be multiplied by 3 (3/1 x 3/4) which would be 9/4, or 2 1/4, cups.

I dont know how to find a .
mina [271]
To find a,construct a line that parallel to AB and DE cutting c, which you could refer to the photo((sorry for my terrible diagram ^^;;

from the photo,we can see that
a= <BCG + <GCE

<BCG=44° (alt.<, AB//FG)
<GCE=20° (alt<, FG//DE)

thus,a= 44°+20° =64°

hope it helps!

Write an indirect proof showing that the diagonals of a parallelogram intersect each other
____ [38]
Its an indirect proof, so 3 steps :-
1) you start with the opposite of wat u need to prove 
2) arrive at a contradiction
3) concludeReport · 29/6/2015261
since you wanto prove 'diagonals of a parallelogram bisect each other', you start wid the opposite of above statement, like below :- step1 : Since we want to prove 'diagonals of a parallelogram bisect each other', lets start by assuming the opposite, that the diagonals of parallelogram dont bisect each other.Report · 29/6/2015261


Since, we assumed that the diagonals dont bisect each other, 
OC≠OA 
OD≠OBReport · 29/6/2015261
Since, OC≠OA, △OAD is not congruent to △OCBReport · 29/6/2015261

∠AOD≅∠BOC as they are vertical angles, 
∠OAD≅∠OCB they are alternate interior angles 
AD≅BC, by definition of parallelogram 
so, by AAS, △OAD is congruent to △OCBReport · 29/6/2015261
But, thats a contradiction as we have previously established that those triangles are congruentReport · 29/6/2015261
step3 :
since we arrived at a contradiction, our assumption is wrong. so, the opposite of our assumption must be correct. so diagonals of parallelogram bisect each other.

Write the sentence as an equation.
bearhunter [10]

The solution to a given word problem by writing it as an equation is k = 253/232

<h3>Expressing word problems in mathematical forms:</h3>

The process of expressing word problems in mathematical forms takes a logical and chronological approach while taking the variables and arithmetic operations given into consideration.

From the given information, to express the word problem in mathematical form, we have:

  • 253 = 232 × k
  • 253 = 232k

Making k the subject of the equation, we have:

k = 253/232
