Answer:

Step-by-step explanation:
Given
The given equation is a differential equation


By separating variable
⇒

Now by taking integration both side

⇒
Where C is the constant




from above equation we can say that
When t will increases in positive direction then
will decreases it means that
will increases, so y will decreases. Similarly in the case of negative t.
Answer:
puppies - 22
Step-by-step explanation:
since the ratio is 2:3, there are 5 parts in total. (2+3=5)
55/5=11 then multiply by parts
puppies- 2×11=22
adults- 3×11=33
check answer by adding- 22+33=55
Answer:
9.3
Step-by-step explanation:
Is means equals and of means multiply
W = 30% * 31
Change to decimal form
W = .30 *31
W = 9.3
Answer:
5 d) 9 1/3
6 d) 2
Step-by-step explanation:
Proportions:
5
7 ⇒ 4
BY ⇒3
BY = 7*4/3
BY = 28/3
28/3 = 27/3 + 1/3 = 9 1/3
BY = 9 1/3
6
12 ⇒ 3
8 ⇒ SX
SX = 3*8/12
SX = 2
