Answer:
(2×10⁴)+(7×10⁵)-(6×10³)= 714000
Answer:
1km=1000m 160m=0.160x4=0.64
Step-by-step explanation:
Ifl = 160m, then:
P = 4 * 160m\\P = 640m
Thus, the perimeter of the base of the pyramid is 640m.
On the other hand, by definition: 1Km = 1000m
By making a rule of three we have:
1Km ---------> 1000m
x --------------> 640m
Where "x" represents the perimeter of the base of the pyramid in Km.
x = \frac {640 * 1} {1000}\\x = 0.64km
Answer:
Step-by-step explanation:
Both expression are the same :
14 = 2(x + 3)
By expansion :
14 = 2*x + 2*3
14 = 2x + 6
Hence ;
Both expression are the same
Weight of one circle :
Final weight on both sides are equal:
Weight on Left hand side = 14
Weight on right hand side = 3*x + 3*x
Weight on Left hand side = Weight on right hand side
14 = 3x + 3x
14 = 6x
x = 14 / 6
x = 2.333
Answer:
122.6 min
Step-by-step explanation:
3 miles = 28 min
13.1 miles=x
28min x 13.1 miles=366.8/3=122.6 min
Answer:
1/18
Step-by-step explanation:
5/9 × 2/2 == 10/18. 1/2 × 9/9 = 9/18.... 10/18 - 9/18 = 1/18.
