Answer:

3560

Step-by-step explanation:

3(10)^3+5(10)^2+6(10)

3× $10^{3}$ +5× $10^{2}$ +6×10

We have to solve the above equation

3× $10^{3}$ = 3×1000=3000

5× $10^{2}$ =5×100= 500

6×10=60

3× $10^{3}$ +5× $10^{2}$ +6×10

=3000+ 500+60

=3560

Hence, the correct answer is 3560

Fred has 30 minutes to do a three-problem quiz. He spent 10 7/10 minutes on question a and 5 2/5 minutes on question b. How much

Answer:Fred has 13 9/10 minutes left for question C

Step-by-step explanation:

The total time that Fred has to do the three-problem quiz is 30 minutes.

He spent 10 7/10 minutes on question A. Converting 10 7/10 minutes to improper fraction, it becomes 107/10 minutes.

He spent 5 2/5 minutes on question B. Converting 5 2/5 minutes to improper fraction, it becomes 27/5 minutes.

Total time that Fred spent on question A and question B is

107/10 + 27/5 = (107 + 54)/10

= 161/10 minutes.

The amount of time that he has left for question C would be

30 - 161/10 = (300 - 161)/10 = 139/10

= 13 9/10 minutes

What is the LCD of 1/6 and 5/12 and 11/18

Oksi-84 [34.3K]

Finding the Lowest Common Denominator of: $\frac{1}{6} ; \frac{5}{12} ; \frac{11}{18} 
$

Here's to find out how it was our LCD: $\frac{1}{6} = \frac{6}{36}$
$\frac{5}{12} = \frac{15}{36}$
$\frac{11}{16} = \frac{22}{36}$
To find the fraction on the right side we had to multiply (and somewhat divide to get the answer)

So, therefore the Lowest Common Denominator of this question would most likely be: $36$

Good Luck!
