Answer:
129.4
Step-by-step explanation:
Calculation for what's the total length from the front of the first bus to the end of the last
First step is to multiply the given number of buses by the length of each one
Hence,
12.6 meters x 9 = 113.4 meters
Second step
Since there are 8 spaces in between we would multiply the 8 spaces by 2 meters
8 x 2 meters = 16
Now let calculate total length from the front of the first bus to the end of the last
16 + 113.4 meters =129.4
Therefore total length from the front of the first bus to the end of the last will be 129.4
Answer:
The answer is B. 1 28/99
Step-by-step explanation:
If you divide 28/99, you will get 0.28282828 and so on. and 1 is a whole number, so 1.28 is what B equals.
Answer:
172 g/mol
Step-by-step explanation:
CaSO4 . 2H2O
Atomic mass of
Ca = 40
S = 32
O = 16
H = 1
Molar mass = 40 + 32 + (16×4) + 2{(1×2)+16}
= 72 + 64 + 2(18)
= 136 + 36
= 172 g/mol
