Answer:
4 large boxes and 2 small boxes
Step-by-step explanation:
4 X 55 =220 books
2 X 30 = 60 books
Total = 280 books
Answer: Ian's calculation was wrong.
Step-by-step explanation:
Given: the amount of fat in 4 cups of chicken soup= 
Then, the estimated amount of fat in 1 cup of chicken soup=
Now, to divide 13 by 4 we can use estimation that 13 is near to 12 anhd 12 divided by 4 is 3.
Therefore, the estimated amount of fat in 1 cup of chicken soup =3
But Ian calculated that the amount of fat in 1 cup soup = 0.331 which is estimated to 0.
Therefore, Ian's calculation was wrong.

Answer:
1) ΔCBF ≅ ΔCDF by (SSS)
2) ΔBFA ≅ ΔDFE by (SAS)
3) ΔCBE ≅ ΔCDA by (HL)
Step-by-step explanation:
1) Since BC ≅ DC and DF ≅ BF where CF ≅ CF (reflective property) we have;
ΔCBF ≅ ΔCDF by Side Side Side (SSS) rule of congruency
2) Since DF ≅ BF and FA ≅ FE where ∠DFE = ∠BFA (alternate angles)
Therefore;
ΔBFA ≅ ΔDFE by Side Angle Side (SAS) rule of congruency
3) Since FA ≅ FE and DF ≅ BF then where EB = FE + BF and AD = FA + DF
Where:
EB and AD are the hypotenuse sides of ΔCBE and ΔCDA respectively
We have that;
EB = AD from FE + BF = FA + DF
Where we also have BC ≅ DC
Where:
BC and DC are the legs of ΔCBE and ΔCDA respectively
Then we have the following relation;
ΔCBE ≅ ΔCDA by Hypotenuse Leg (HL).
