Answer: This is a problem of inverse variation, where the number of days that the food lasts is inversely proportional to the number of soldiers in the fort. We can use the formula:
d = k / s
where d is the number of days, s is the number of soldiers, and k is a constant of proportionality. We can find the value of k by using the initial information:
48 = k / 1500 k = 48 * 1500 k = 72000
Now we can use the information after 13 days to find the new number of soldiers. Let x be the number of soldiers who joined the fort. Then we have:
25 = 72000 / (1500 + x) 25 * (1500 + x) = 72000 37500 + 25x = 72000 25x = 34500 x = 1380
Answer: The number of soldiers who joined the fort after 13 days is 1380.
Answer:

Step-by-step explanation:
All you have to do is subtract 4:30 and 4:00 and get 30 minutes.
4 units to the right of 4
8 units to the left of 4
8 units to the right of 4
Answer:
C. 8 units to the left of 4
Step-by-step explanation:
We are asked to find the the position of located on a horizontal number line.
We know that negative numbers are located on the left side side of number line and positive numbers are located on the right side of number line.
4 will be located to the 4 units right from zero and negative 8 will be located 8 units left from 8.
Therefore, option C is the correct choice.
Answer:
8 units to the left of 4
