21v + 8 - 12v - 7 + 3t - 1t = (combine like terms)
9v + 2t + 1 <==
First, simplify each one.
9.98 x 10^6 = 9980000
7.3 x 10^7 = 73000000
Next, subtract the freight from the aircraft
73000000 - 9980000 = 63020000
Round the decimal point to the first significant digit, and place the amount of place values the decimal point moved to the left as a power sign, over 10.
63020000 = 6.302 x 10^7
6.302 x 10^7 is your answer
hope this helps
Answer:
Step-by-step explanation:
In ΔJOY and ΔLAF,
If ∠O ≅ ∠J
And 
Then ΔJOY ~ ΔLAF
By SAS property of similarity of two triangles.
(If two corresponding sides of the triangles are proportional and angles between these sides are equal)
Answer:
179.5 - 180.5
Step-by-step explanation:
Time is a continuous variable. The minimum sleep time per night per subject here, is given as 1 minute.
Larger sleep times could be 1.08 minutes, 2.99 minutes, and other continuous/infinite values. Remember there are 60seconds in a minute and in-between seconds, there are milliseconds. So time is a continuous variable.
In this case though, our measurement of time is given in whole number units (integers). Our precision of measurement is 1 unit. We have an observed value of 180 minutes (the first subject's sleep time). The real limits of this value are 179.5 to 180.5
It's just dividing out the factoring to their simplest form.
The bold numbers are the answers that go in the circles.
1. 16 < 8 and 2
8 < 2 and 4
4 < 2 and 2
2. 42 < 14 and 3
14 < 7 and 2
3. 40 < 2 and 20
20 < 10 and 2
10 < 2 and 5
4. I'm not able to see the rest of the factoring tree
