Answer:

The age of Mr. Collins is 30 years and

The model which represent the problem is, The age of Mr. Collins is 3 × 10

Step-by-step explanation:

Given as :

The age of Adam = 10 years

The age of Mr. Collins = x years

The age of Mr. Collins = 3 times the age of Adam

Or, x = 3 × The age of Adam

Or, x = 3 × 10

∴ x = 30

So, The age of Mr. Collins = x years = 30 years

The model which represent the problem is, The age of Mr. Collins = 3 × 10

Hence The age of Mr. Collins is 30 years and

The model which represent the problem is, The age of Mr. Collins = 3 × 10

5. Given the following triangle side lengths, identify the triangle as acute, right or obtuse. Show your work.

Roman55 [17]

Refer to the figure shown below.
We shall review each of the three given measurements and decide what type of triangle we have.

Measurement a.
a=3, b=4, c=5.
For a right triangle, c² = a² + b² (Pythagorean theorem)
a² + b² = 3² + 4² = 9 + 16 = 25
c² = 5² = 25
Answer:
This is a right triangle, because c² = a² + b².

Measurement b.
a=5, b=6, c=7.
For an acute triangle, c² < a² + b².
a² + b² = 5² + 6² = 25 + 36 = 61
c² = 7² = 49
Answer:
This is an acute triangle, because c² < a² + b².

Measurement c.
a=8, b=9, c=12.
For an obtuse triangle, c² > a² + b².
a² + b² = 8² + 9² = 64 + 81 = 145
c² = 12² = 144
Answer:
This is an acute triangle because c² < a² + b².
