Answer:
About 473 quails.
Step-by-step explanation:
Exponential equation with as the initial amount and rate of r is:
After 5 years the population will be:
So the population will be about 473 quails.
Answer:
see attached
Step-by-step explanation:
Each grid square represents 5 m, so the distances shown on the grid will be scaled appropriately.
<h3>Scale drawing</h3>
The 25 m base dimension will be represented by (25 m)/(5 m/square) = 5 squares.
The 30 m height dimension will be represented by (30 m)/(5 m/square) = 6 squares.
The attached drawing shows the triangle with base 25 m and height 30 m on a 5 m grid.
Answer:
Pole^2 = 221^2 - 21^2
Pole^2 = 48,841 -441
Pole^2 = 48,400
Pole = 220 cm
Answer is B
Step-by-step explanation:
We know that the perimeter is the all the sides added up together. Generally, you have
, where l is length and w is width.
For a square, all sides are of the same length, so you can write
, where x is any side.
If the smallest perimeter is 14, then
, so x is 3.5. If the largest perimeter is 72, then
, so x is 18.
Therefore, you have 3.5 ≤ x ≤ 18.
I think the answer would be 16, Hope this helps
