Alica had 10/12 of fabric she used 8/12 for a pillow how much fabric dod she have left? Explain how you found your answer .

1 answer:

5 0

If she has 10/12 and uses 8/12 then you just subtract.
Since the denominators are the same you just subtract 10-8 and get 2
the denominator is the same for your answers and so it is
2/12

Answer:

A: geometric; 4 times

B: arithmetic: 4 more

Step-by-step explanation:

An arithmetic model is a linear model, where the rate of change is constant. Growth or decay is by a constant amount from one interval to the next.

A geometric model is an exponential model, in which the rate of change is proportional to the amount. Growth or decay is by a constant factor from one interval to the next.

The equation for the sequence is given in "explicit" form:

$A_n=2^{2n}$

The exponent can be split so this can be rewritten as ...

$A_n=(2^2)^n=4^n$

If this were written in recursive form, it would look like ...

$A_0=1,\ A_n=4\times A_{n-1}$

The fact that terms are related by a constant factor tells you the model is geometric. The factor tells you each hour the population is 4 times what it was in the previous hour.

The given equation is in "recursive" form. It tells you each term is 4 more than the previous one. This constant difference between terms means the model is arithmetic.
