For the answer to the question above asking, which proportion would correctly find the length of the tree's shadow if<span> a 15 foot flagpole casts an 11 foot shadow. At the exact same time a 28 foot tree casts a shadow?
</span>the answer is 15/11=28/x, and the tree's shadow is 20.53 feet long.
The answer is 80 ft.
Based on the diagram we know that the tree triangle and the building triangle are similar triangles where the lengths of each are proportional to the other.
The lengths of the triangle the tree makes are half of the lengths of the building triangle. So this problem can be solved using ratio and proportion:
to solve for x, all you need to do is cross multiply then divide.
The answer is then 80ft.
Another way to solve this is just by using logic. If the lengths of the tree triangle is half of the building, simply divide the lengths of the building triangle by two.
160ft/2 = 80ft.

Answer:
value of expression = 12
Step-by-step explanation:
[(-10+2)-1]+(2+3)
= [(8)-1]+(5) ∵according to PEMDAS, we first solve the Parenthesis
= (7)+(5)
= 12
Answer:
3ab(4a + 5b)
Step-by-step explanation:
Given
12a²b + 15ab² ← factor out 3ab from each term
= 3ab(4a + 5b)
