Answer:
C
Step-by-step explanation:
The 10 inch sides will produce 10 / 3 = 3 squares and 1 inch left over.
The 18 inch sides will produce 18/3 = 6 squares with nothing left over.
The number of squares is 3 * 6 = 18
C
Answer:
11.1m/s to the right
Step-by-step explanation:
Momentum before = momentum after
m₁u₁+m₂u₂=(m₁+m₂)v
1000(20)+800(0)=(1000+800)v
20000 = 1800 v
v= 11.1m/s to the right (to the right because the number is positive)
Answer:
x = 61.6 degree
Step-by-step explanation:
take x degree as reference angle
using sin rule
sin x = opposite / hypotenuse
sin x = 4.8 / 5.4
sin x = 0.88
x = 
x = 61.64
x = 61.6 degree
In triangle ABC,
AB^2 = CA^2+CB^2 (pyth. theorem)
AB^2 = 9^2 + 12^2
AB = √ 9^2+12^2
AB = √ 225
AB = 15
