6. Determine if the sequence is arithmetic or
geometric, and the common ratio or
difference.
-4,-2.5, -1, 0.5, 2,......
A. Arithmetic; d = 1.5
B. Arithmetic; d = 2
C. Geometric; r = 0.5
D. Geometric; r = 2

Answers

Answer:

A. Arithmetic; d = 1.5

Step-by-step explanation:

-4, -2.5, -1, 0.5, 2

Looking at the sequence, we can see that the numbers increase. This means our common ration or difference will be positive.

Let's look at common ratios first.

To find the common ratio, divide one term from the term after it.

r = a₂ ÷ a₁

r = -2.5 / -4

Divide.

r = 0.625

To see if this is the common ratio, we want to test this with the other numbers of the sequence.

r = a₃ ÷ a₂

r = -1 / -2.5

r = 0.4

This is not consistent; therefore our sequence is not geometric.

Let's look at common differences next.

To find the common ratio, subtract one term from the term after it.

r = a₂ - a₁

r = -2.5 - (-4)

Simplify.

r = -2.5 + 4

Add.

r = 1.5

To see if this is the common difference, we want to test this with the other numbers of the sequence.

r = a₃ - a₂

r = -1 - (-2.5)

Simplify.

r = -1 + 2.5

r = 1.5

This is consistent; therefore we have found our common difference of this arithmetic sequence.

A. Arithmetic; d = 1.5

Hope this helps!

Answer: 27 inches

Explanation: Divide the shape into one square and one rectangle, creating two separate shapes.

Find the area of each shape by multiplying length by height.

For the square, multiply 3 x 3 = 9 in.
For the rectangle, multiply 9 x 9 = 18 in.

Next, add both solutions together to get your answer. 9 + 18 = 27 in.

The area of the figure is 27 inches.

Answers

Answer:

Step-by-step explanation:

Shelby is collecting 15 1/2 pounds of Peebles for his geology experiment

She collects the pebbles in a bucket that holds 3 5/8 weight pounds

Therefore the number of buckets that will he required can be calculated as follows

= 15 1/2 ÷ 3 5/8

= 31/2 ÷ 29/8

= 31/2 × 8/29

= 124/29

A chef cooked vegetables for 22 customers. The chef cooked 1/3 pound of potatoes and
1/4 pound of green beans for
each customer.

How many pounds of vegetables did the chef cook for these customers all together?

Answers

Answer:

The chef cooked 1/3 pound of potatoes and

1/4 pound of green beans for

each customer.

so. Sum of all vegetables for one customer = 1/3 pound of potatoes + 1/4 pound of green beans

                                                                        = 1/3 + 1/4 pound

                                                                        = 7/12 pound

so. Sum of all vegetables for 22 customer = (7/12 pound ) 22

                                                                      = 22/12 pound

                                                                      = 11/6 pound
