<em>Option:</em>
<em>a. for every 13 dogs, there are 25 cats.
</em>
<em>b. there are twice as many cats as dogs at the shelter.
</em>
<em>c. the shelter has more dogs than cats.
</em>
<em>d. there are 25 animals in the shelter.</em>
Answer:
a. for every 13 dogs, there are 25 cats.
<em></em>
Step-by-step explanation:
Represent Dogs with D and Cats with C;
So;

By comparison:


This implies that:
For every 13 D, there are 25 C
Hence: Option A is true
Answer: -4 is the answer
Step-by-step explanation:
Answer:
Number of full size cars = 900
Step-by-step explanation:
The ratio of medium size cars to compacts is 7 to 5 and the ratio of compacts to full-size cars is 8 to 9. Since compact cars are there in both ratios , we need to make the number in the ratio for compact cars to be the same.

Multiply by 8 on numerator and denominator


Multiply numerator and denominator by 5.

Ratio of medium, compact and full size are in ratio 56,40,45.
Total number of cars =2820.
(56 + 40 + 45)x = 2820
x = 
x = 20
Number of full size cars =
=900
I don’t think so, I may be wrong
Using the Laplace transform, the value o y' − 2y = (t − 4), y(0) = 0 is⇒y(t) = 0 e^-t + u(t -1)e^1-t
Laplace rework is an critical rework approach that is in particular useful in fixing linear normal equations. It unearths very huge applications in regions of physics, electrical engineering, control optics, arithmetic and sign processing.
y' − 2y = (t − 4),
y(0) = 0
Taking the Laplace transformation of the differential equation
⇒sY(s) - y (0) + Y(s) = e-s
⇒(s + 1)Y(s) = (0+ e^-s)/s + 1
⇒y(t) = L^-1{0/s+1} + {e ^-s/s + 1}
⇒y(t) = 0 e^-t + u(t -1)e^1-t
