Answer:
Step-by-step explanation:
Initial number of sick wolves = W(0) = 10
At time t, no. of sick wolves = W(t)
Given that disease is spreading at a rate proportional to the product of the time elapsed and the square root of the number of sick wolves:
Mathematical model of above case is:
Divison: 45➗15= 3
Subtraction: 45-15= 30
Answer: 102
Step-by-step explanation:
6x6 to get the square
7x6 to get part of the other shape
21 -6-7 to get the triangle that we don't have a number
8x6 to get a square but then divide by 2 too get the triangle.
now add all together to get 102
Drawing a picture definitely helps! since BD is 6", it is split evenly into 3 and 3. AC is the same except it splits into 4 and 4. because AC and BD are perpendicular to each other, the crossing lines form a 90 degree angle. in this case, the missing side is 5 because the sections form a pythagorean triple (3, 4, 5). you could do the pythagorean theorem (a^2 + b^2= c^2) but having some pythagorean triples memorized will help a lot. i hope this helped!
