The grandson is 9 years old.
This would mean that the grandpa is 54.
9x6=54
54/6=9
Answer:
Step-by-step explanation:
3) 9732.8/20 = <u>486.64</u>
4) 0.75x4= 3
43.6- 3= 40.6
40.6/30= <u>1.35</u>
Answer:
Part) A
Density=Mass/volume
Part) B
volume displaced by crown> volume displaced by gold brick
Step-by-step explanation:
Density=Mass/volume
Mass=Density(volume)
The jeweler replace gold with equal weighed silver but as gold has a higher density than silver, the jeweler must put more volume of silver to balance it. Hence the overall volume of crown increases.
2. In bath, Archimedes discovered that the amount of water displaced in tub is equal to the volume of the body that was placed in it.
He then compares the volume of water displaced by a gold brick and the volume of water displaced by the jeweler made crown and when the volumes do not come equal then there is evidence. The volume of water must rises higher in case of crown than in case of brick of gold due to inclusion of silver in it!
X1,2 = + 5.292 i think but i cant see the awsner choice
Answer:
Step-by-step explanation:
The volume of the bigger rectangular tank is length × breadth ×height
V= l×b×h
V=80×60×40
V=192000
Volume of the smaller rectangular jar that will filled up the bigger one
V=l×b×h
V=20×10×15
V=3000
Then, the amount that will filled it up.
Bigger Volume / smaller volume
192000/3000=64
Therefore, 64 of the smaller volume will filled the bigger volume
