Answer:

Arithmetic sequence

Step-by-step explanation:

A sequence is described as an arithmetic sequence when there is a common difference between the numbers

A sequence is a geometric sequence when there is a common ratio between the numbers

12,10,8

10-12= -2

8-10= -2

10/12= 0.83

8/10= 0.8

Hence the sequence is an arithmetic sequence with a common difference of -2

A. Sarah Smartshopper receives ten cents off per gallon on gas for every $100 she
Wewaii [24]

Using proportions, it is found that her discount is of $0.29664.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount.

In this problem, the total amount she spent on gas is given by:

T = $45.23 + $102.34 + $13.67 + $34.56 + $48.72 + $52.12 = $296.64.

Considering that she receives ten cents off per gallon on gas for every $100 she spends, we apply the <em>proportion </em>to find that her discount is given by:

D = 0.1 \times \frac{296.64}{100} = 0.29664

Her discount is of $0.29664.

Answer:

  • 163 in²

Step-by-step explanation:

To find the area, I divided the shape into squares and rectangles. Then, I found the area of the squares and rectangles and added them,

  • Area = (7 x 7) + (18 x 5) + (6 x 4)
  • => (49) + (90) + (24)
  • => 163 in²

Hence, the area is 163 in.²
