Answer:

20 rabbits, 10 chickens

Step-by-step explanation:

Because chickens and rabbits each have 2 eyes, the number of animals is 60 ÷ 2 = 30.

Let's say that all of the 30 animals are chickens. There would be a total of 30 × 2 = 60 legs.

So the extra (100 – 60) = 40 legs must have come from the rabbits.

Every rabbit has (4 – 2) = 2 more legs than a chicken.

So there are 40 ÷ 2 = 20 rabbits and 30 – 20 = 10 chickens.

What are the solutions of the inequality (x-3)(x+5)&lt;=0
GarryVolchara [31]

Assuming that the inequality you were going for was a ≤, set both polynomials less than or equal to 0.

x - 3 ≤ 0

x + 5 ≤ 0

For the first equation add 3 to both sides of the inequality. For the second, subtract 5 from both sides.

x ≤ 3

x ≤ - 5

These would be your solutions I guess, however, if you want to expand upon that, your actual answer is (- ∞, - 5] because if you were to plot these two inequalities on a number line, that is where the overlap would occur.

A young person decides to put aside some money for retirement by putting $1,000 in a 30-year savings bond that pays 3.0% simple
Pavel [41]

Answer:

2427.26 $

Step-by-step explanation:

Just use this formula when you have such type of problems:

N = N° (1 + %)^t

Where N = final amount

           N°= initial amount

           t = peroid of time

Now let's solve:

N = 1000(1 + 0.03)^30

N = 2427.26
