Answer:
The sum of 1.8 and 1.56 is 3.36 according to the model
Sum of decimals
Given the expression 1.8 + 1.56
Using the partial sum method
1.8 + 1.56 = (1.0 + 0.8) + (1.0+0.56)
Regroup as whole and decimal number
1.8 + 1.56 = (1.0 + 1.0) + (0.8 +0.56)
1.8 + 1.56 = 2.0 + 1.36
1.8 + 1.56 = 3.36
Hence the sum of 1.8 and 1.56 is 3.36 according to the model
Answer:
200 √17
Step-by-step explanation:
distance between two points (x,y) and (x',y')
D² = (x' - x)² + (y' - y)²
D² = (500 - (-300))² + (400 - 200)² = 640000 + 40000 = 680000
D = √680000 = √4 x 17 x 10000 = 200 √17
