Add up all the number of students all together:
12+13+14+9
48
Now, Divide the total amount of students (48) by the amount of numbers you added (in this case, 48/4 because we added 4 numbers wich are 12+13+14+9)

Answer:
1063 ft
Step-by-step explanation:
For shadow problems, we assume the sun's rays are parallel, so the triangles formed are similar. That means the ratio of height to shadow length is the same for each object.
h/(580 ft) = (5.5 ft)/(3 ft)
h = (5.5 ft)(580/3) ≈ 1063 ft
The height of the monument is about 1063 feet.
Answer:

Answer:
-q
Step-by-step explanation:
We know that we are trying to find an expression equivelant to p - q:
p - q can be p - 1q
We can then put parenthesis around -1q:
p + (-1q)
We then can simplify:
p + (-q)
105 × $8.72 = $915.60
$915.60 + $348 = $1,263.60
Mary paid $1,263.60 for the stock.
