DENSITY =MASS/VOLUME
OR MASS = DENSITY X VOLUME
DENSITY =1.5 g/ml AND VOLUME = 10 ml
MASS = 1.5 x 10 = 15 g
Answer:
7 ÷ 5
Step-by-step explanation:
1/5 of 7 is equal to 1/5 times 7/1, which will simplify to 7/5, or 7 ÷ 5.
Answer:
Yes.
2 feet
Step-by-step explanation:
Pieces of copper that Arsenio needs in total = 27 pieces
Length of each piece of copper tubing that he needs = 2/9 foot
Length of available tubing = 8 foot
Since, the length of each piece is 2/9 foot, the length of 27 pieces would be:
This means, Arsenio needs 6 feet in total for the copper tubing. Since he got 8 feet in total, he has sufficient amount of tubing available.
After making the 27 pieces, he will be left with 8 - 6 = 2 feet of tubing.
It is 3i.
The square root of -9 is the square root of -1 times the square root of 9.
So: the square root of 9 is 3, and the square root of -1 is called i (this doesn't actually exist, it's just imaginary).
Then, the square root of -9 is 3i.
