Answer:
2250
Step-by-step explanation:
What's the trapezoidal lengths?
Answer:
See below.
Step-by-step explanation:
The density = mass / volume
= 612 / 245
= 2.50 g/cm^3.
The literature states a density of 2.70 for the density of aluminium. The only other metal which is close to this value is strontium ( d = 2.64) which is a silvery colour so it might be that. One way to find out which it i s to see if the metal reacts with water. Aluminium does not while strontium does.
Answer:
15.6cm
Step-by-step explanation:
Answer:
The value of w is 7.
Step-by-step explanation:
According to Pythagoras theorem,
Hypotenuse²=Perpendicular²+Base²
H²=P²+B²
Here,
Hypotenuse given=7√2
w=y
Perpendicular=Base=x
(7√2)²=x²+x²
49*2=2x²
(49*2)/2=x²
49=x²
√49=x
7=x
Perpendicular=x=7
