Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
Formula is f(x) - ab^x. so we would need to get b. we would have to change the percentage to a decimal. so shift it 2 times to the right. which is 0.015 = b. hope this helps :D
Answer:
Mme Q spent more time answering emails from students by 10 minutes
Step-by-step explanation:
Here we have
Time spent by Mme Q in answering mails on Friday given by
5/6 Hour = 50 minutes and
7/12 Hour = 35 minutes
Total time spent on Friday = 85 Minutes or
5/6 + 7/12 = 17/12 Hours
Time spent by Mme F in answering mails on Friday given by
1/2 Hour = 30 minutes and
3/4 Hour = 45 minutes
Total time spent on Friday by Mme F = 75 Minutes or
1/2 + 3/4 = 5/4 Hours
Therefore, Mme Q spent more time answering emails from students by 85 - 75 = 10 minutes.
Answer:
m = -1, b = 5.
Step-by-step explanation:
We can find the slope, <em>m</em>, by plugging in our coordinates into the slope formula: 
. That gives us the slope. Now we can fill that in the slope intercept formula: 
. We know one of the coordinates and the slope, which allows to find the y-intercept. We know that for every 1 unit down on the line, we move 1 unit right, and vice versa. Meaning we can just count down (or up in this case), so, (-2, 7), (-1, 6), (0, 5). Therefore, our y intercept is 5.
Answer:
Step-by-step explanation:
1.The prime factorization of 54 is: 2 x 3 x 3 x 3.
2.The prime factorization of 24 is: 2 x 2 x 2 x 3.
3.The prime factors and multiplicities 54 and 24 have in common are: 2 x 3.
4.2 x 3 is the GCF of 54 and 24.
Answer: GCF(54,24) = 6.
