5 x 10 = 5x10¹ = 50
5 x 100 = 5x10² = 500
5 x 1000 = 5x10³ = 5000
5 x 10,000 = 5x10⁴ = 50,000
Answer:
For #14, (around) 108 times.
#15 = 53
Step-by-step explanation:
14)
2.69*10^5 = 269000
2.5*10^3 = 2500
269000/2500 = 107.6
Rounding up, we get 108
15)
√(53 - 8)2 + (31 - 3)2
= √(45)2 + (28)2
= √2809
= 53

Answer:
EY = 60
DW = 68
DE = 128
Step-by-step explanation:
Given
As YW is the perpendicular bisector of EF, then EY = FY
FY = √(FW² - YW²) = √(68² - 32²) = 60
⇒ EY = 60
As WX is the perpendicular bisector of DF, then DW = FW
As FW = 68, then DW = 68
As WZ is the perpendicular bisector of DE, then DZ = EZ = 64
Therefore, DE = DZ + EZ = 64 + 64 = 128
Answer:
The new drawing at the left enlarges the size of the original drawing.
Step-by-step explanation:
If I draw the map at the left using a scale of 0.5 cm : 1 cm.
That means the 0.5 cm length in the previous drawing is redrawn in the new map as 1 cm length.
Since 1 cm is larger than 0.5 cm and it is two times of 0.5 cm, so the new drawing at the left enlarges the size of the original drawing. (Answer)
