First thing to do is set up your equation:
45/x = 20/100
Cross multiply
4500 = 20x
And divide by 20
Answer: 225 people were surveyed
64x2y2 the twos are powers of ten so you put them up top.
Answer: The fox population decrease 1.298% every month.
Step-by-step explanation:
Since we have given that
Initial foxes = 170000
Every 7 months, the population loses 
So, we need to find the rate of change in population every month.
So, we will use "Unitary method":
So, In every month, the population loses 
So, the percentage would be

Hence, the fox population decrease 1.298% every month.
Answer:
The ladder has to be 65 feet long to the nearest foot.
Step-by-step explanation:
The height of the chimney from the ground is the sum of the height of the wall and the height of the chimney.
Therefore, the height of the chimney from the ground = (30 + 33) = 63 feet.
Now, the ladder makes a right triangle with the ground and the chimney and the ladder makes an angle of 75.5° with the ground.
Therefore, using trigonometry we can write,

⇒ The length of the ladder = 65 feet.
Hence, the ladder has to be 65 feet long to the nearest foot. (Answer)
The phrase "5 increased by t" written in algebraic expression is (5 + t).
<h3>Algebra</h3>
can be written as
(5 + t)
For instance,
if t = 25
(5 + t)
= 5 + 25
= 30
Therefore, the phrase "5 increased by t" written in algebraic expression is (5 + t).
