A company expected to produce 200 units of its product, the Bone, in 20X3. In fact, 260 units were produced. The standard labour cost per unit was $70 (10 hours at a rate of $7 per hour). The actual labour cost was $18,600 and the labour force worked 2,200 hours although they were paid for 2,300 hours. Require:
a. What is the direct labour rate variance for the company in 20X3?
b. What is the direct labour efficiency variance for the company in 20X3?

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".

a triangular prism is a 3 dimensional shape composed of triangles and rectangles. it is made from two triangular bases and three rectangular sides.  

answer: two angles are called supplementary if they add up to 180°. example: the two angles (140° and 40°) are supplementary because they add up to 180°.
