Step-by-step explanation: If Professor Lam grades 4 papers per hour, in 11 hours he will graded 44 papers. (11 x 4= 44). He had previously graded 6 papers giving him a total of 50 papers graded. His assistant can grade 5 papers per hour, thus it would take him 10 hours to grade the same amount of papers as Professor Lam. (10 x 5= 50) Thus: 11 hours Professor Lam 50 papers graded; 10 hours his assistant 50 papers graded.
Answer:

Step-by-step explanation:
The square in the middle has a length and width of 3, so multiply. <u>9</u>.
All of the triangles have a base of 3 and a height of 2. The area equation for triangles is

So base*height is 6. Divide that by 2 or multiply by 1/2.
You get 3. There are 4 triangles, so multiply <em>that</em> by 4. <u>12</u>.
Add 12 and 9 together, and you get:

Answer:
52.
Step-by-step explanation:
shaded = (3²) + (2²)
shaded = 9 + 4
shaded = 13
Unshaded = (3 x 2) + (2 x 3)
Unshaded = 6 + 6
Unshaded = 12
All = 12 + 13
All = 25
100 / 25 = 4
4 x 13 = 26 x 2
26 x 2 = 52.
