Answer:
Age of Rocky = 5 months
Step-by-step explanation:
Given that:
Equation for calculating puppy's weight
p = 3a + 2
Here,
p = weight of puppy
a = age in months
We have to find the age if the weight is 17 pounds
Putting p=17 in given equation
17 = 3a + 2
17 - 2 = 3a
3a = 15
Dividing both sides by 3
Hence,
Age of Rocky = 5 months
Answer:
The original height of tree is 18 m.
Step-by-step explanation:
Consider the correct question is "A tree is broken at the height of 5m from the ground and its top touches the ground at a distance of 12m from the Base of the tree. Find the original height of the tree."
A tree is broken at the height of 5m from the ground.
Let the height of the tree is (x+5) m.
After broken, it will form a right angle triangle with hypotenuse x, base 12m and perpendicular 5 m.
Using Pythagoras theorem,
Taking square root on both sides.
Height of tree =
Hence, the height of tree is 18 m.
