Answer:
9.22
Step-by-step explanation:
The distance formula is ...
d = √((x2 -x1)^2 +(y2 -y1)^2)
Using the given coordinates, the distance between them is ...
d = √((8-(-1))^2 +(0 -(-2))^2) = √(9^2 +2^2) = √85 ≈ 9.22
The length of AB is about 9.22 units.
We know that the commercial plane travels 570 miles/hour. To find out how many miles does the plane travel, we do:
570 × 7 = 3990 miles.
Therefore, the plane travel 3990 miles.
Answer: 48
Step-by-step explanation:
V = b x h
V = 8 x 6
V = 48
Answer:
We can not solve for a unique cost for each soldier.
Step-by-step explanation:
Let x be the daily cost for legionaries and y be the daily cost for archers.
Upon using our given information we will get a system of linear equations as:


Now we will solve for x from our 2nd equation,

Now we will substitute this value in our 1st equation.

We can see that -3y cancels out with 3y and 9 is not equal to 10. So this is an unsolvable system. Therefore, we can not find a unique cost for each soldier.
