7.380 times 10 to the 9th power (or 7.38 times 10 to the 9th power)
My teacher taught me to make an imaginary decimal and 0 at the beginning of the number and then move the decimal to the end of the number... idk that may be the wrong way to do it but you can try :/
Answer:
x = 125
Step-by-step explanation:
Ok so we already established that AIA are congruent. So two angles will equal 55 degrees. All angles in a parallelogram add up to 360 degrees, and there are two pairs of matching angles opposite of each other.
So we take the two 55 degree angles and subtract them from 360:
360-110 = 250
Now there are two identical angles left, one of them is x, that equal a total of 250, so divide by two:
250/2
=125 degrees
Answer:
1,3,4
Step-by-step explanation:
ıf we rearrange formula we can obtain
p=nrt/v
t=pv/nr
v=nrt/p
r=pv/nt
Answer: Mean = 52.8 mins
Step-by-step explanation:
We have lapses of 30 minutes, so we can write the average for each, this means that:
0 < t < 30 can be averaged to the middle of the range: 15 min.
Doing this, we have that:
7 students 15 min
27 students 45 min
12 students 75 min
4 students 105 min.
Now we can calculate the mean:
mean = (x1*n1 + x2*n2 + ...)/N
where x1 is the amount of time 1, and n1 is the number of students associated to that time and so on. N is the total number of students
Mean = (7*15min + 27*45min + 12*75min + 4*105min)/(7 + 27 + 12 + 4)
Mean = 52.8 mins
