John blinks every 6 seconds, Jeremy every 4 seconds, so they both will blink next on a common factor of 6 and 4, or an LCD, that'd be 12 seconds later, so at 00:00:12.

A scientist measures a substance to be 0.6 grams. Calculate the percent of error in the measurement. Show all work for full cred
Anni [7]
A measurement of 0.6 grams means that the 'true' answer lies between
<span>0.55 and 0.65 </span>

In general, the uncertainty in a single measurement from a single instrument is half the least precise decimal given for the instrument.
The precision for this measurement is in the tenths place.
so we take 0.1 /2 = 0.05, and divide by the measurement

<span>0.05 / 0.6 = 0.08333 = 8.3 %</span>

Naddik [55]

Answer:

3.3

Step-by-step explanation:

=  >  \frac{4 \frac{2}{5} }{1 \frac{1}{3} }  \\  \\  =  >  \frac{ \frac{20 + 2}{5} }{ \frac{3 + 1}{3} }  \\  \\  =  >  \frac{ \frac{22}{5} }{ \frac{4}{3} }  \\  \\  =  >  \frac{22}{5}  \times  \frac{3}{4}  \\  \\  =  >  \frac{11}{5}  \times  \frac{3}{2}  \\  \\  =  >  \frac{33}{10}  \\  \\  =  > 3.3

The table below shows all of the possible outcomes for rolling two six-sided number cubes.
Mice21 [21]

C. 1/4

There is a table with 36 possible outcomes. 9 of them are desired outcomes because they have an even number rolled first and then an odd number rolled second (a few random examples from the table would be 2,1, 2,3, 4,1, 4,5, 6,3 etc.)

All we have to do is make a fraction of the desired outcomes over the total number of possible outcomes. 9/36. That can be simplified into 1/4 and <em>voilà</em>, there is your answer.

Hope this helped ッ

The measure of an angle is 6°. What is the measure of its complementary angle?
stealth61 [152]

Answer:

84 degrees.

Step-by-step explanation:

First, let's define what a complementary angle is. It's when two angles add up to 90 degrees. So we do 90-6=84 and 84+6 does in fact equal 90, so they are complementary.

I don't think that you put parentheses around any numbers because when I solve it with parentheses between numbers I get other numbers like 16 or 17
