If you would like to convert meters to kilometers, you can calculate this using the following step:
1 meter = 0.001 kilometers
1900 m = 1900 * 0.001 km = 1.9 km
If the tunnel is about 1900 m = 1.9 km long, then this is a little less than 2 km, because 1.9 km < 2 km.
Answer:
4n=y
Step-by-step explanation:
because 4 is the number of characters they use and n is the number of spaces or characters it takes
1. {26, 21, 28, 31, 9, 28, 16, 18, 21, 23, 29, 24, 19, 22, 25, 28}<br>
Find the mean.

Answer:
368 / 16 = 23
Step-by-step explanation:
Add them all, then divide by how many numbers are in the data set.
<span><span>9 - 3 = 6, 15-9 = 6 the difference is 6, So d = 6
</span><span>
First term: a1 = 3
Sn = n*(a1 + an)/2
Sn = n*(a1 + a1 + (n-1)*d)/2
Sn = n*(2*a1 + (n-1)*d)/2
</span></span>
<span> <span>substitute 26 for n
</span>
S26 = 26*(2*a1 + (26-1)*d)/2 </span>
<span><span>substitute 3 for a1
</span><span>
S26 = 26*(2*3 + (26-1)*d)/2 </span></span>
<span><span>substitute 6 for d
</span><span>
S26 = 26*(2*3 + (26-1)*6)/2 </span><span>
</span><span>
S26 = 2,028</span></span><span><span>
</span><span>
</span></span>
D. because each day =34 and it is 5days 5×34= 170 so the answer is more than 4 gallons
