-2 1/2 - (-1 3/4) ? ​

Mathematics
1 answer:
Olin [163]3 years ago
8 0

Answer:

- 3/4

Step-by-step explanation:

-2 1/2 - (-1 3/4)

Subtracting a negative is like adding

-2 1/2 + (1 3/4)

Get a common denominator of 4

-2 2/4 + 1 3/4

The signs are different so we subtract and take the sign of the larger

2 2/4 - 1  3/4

Borrowing from the 2

1 4/4 + 2/4 - 1 3/4

1 6/4 - 1 3/4

3/4

2 2/4 was larger and it was negative so we add a negative sign

- 3/4

A population of rabbits, in the absence of other factors, grows at a rate proportional to the current population: specifically,
erastova [34]

Answer:

G = kX

Where:

G - Growth rate

X = the initial/current population of rabbit

k = is the constant of proportionality.

Step-by-step explanation:

As we are told in the question, the growth rate is proportional to the current population. This information gives us the initial value needed to solve to find the population of rabbits at any given time.

Other information given as needed for computation and we are not asked to do anything further.

<u>Analytically,</u>

If X = 100

And it triples in 2 years. That is, 3*X = 300. 2 years is 24 months.

This gives us the monthly growth rate = 300/24 = 12.5 => 12 to 13 rabbits per months.

Foxes kill 2 rabbits per month. This implies that 2*24 = 48 rabbits are killed by Foxes in 24 months.

By implication, the population of rabbits in 2 years will be

X (in 2 years) = 300 - 48 = 252 rabbits.

Multiple choice question: A square mosaic is made of small glass squares. If there are 196 small squares
Anni [7]

Answer:

14 squares

Step-by-step explanation:

1. We know if the mosaic is a square shape, all sides are the same length and consist of the same amount of squares

2. Area is L×W, so in this case A×A=196

3. We can test this by replacing A with 14 and seeing if the answer is correct.

4. 14×14=196 is true

This can also be done by finding the square root of 196.
