0.7 as a fraction would be 7/10
Answer: 1/6
Step-by-step explanation: There are 4 primes. So the probability for the first draw is 4/9. Since the card is not replaced, the second probability is 3/8. 3/8 * 4/9 is 12/72, which simplifies into 1/6.
Answer:y=44°
Step-by-step explanation:
Sin y =cos [90°-y]
It is Given that sin y =cos (y+2°)
Cos[90°-y]=Cos(y+2°)
90°-y=y+2°
88°=2y
y=44°
Answer:
x = 53
Step-by-step explanation:
Vertical angles are equal
so
3x - 10 = 149
3x = 159
x = 159 / 3
x = 53
The balanced chemical reaction is written as:
C + O2 = CO2
We are given the amounts of the reactants to be used in the reaction. We use these values for calculations. Since there is oxygen that is left in the reaction then the limiting reactant would be carbon. We calculate as follows:
16.8 g C ( 1 mol / 12.01 g) ( 1 mol CO2 / 1 mol C ) ( 44.01 g / 1 mol) = 61.56 g CO2 produced
