The common difference is -5
right now, a₁₂ = 22

to get a₁, subtract 5 each time you subtract one from the subscript

so

a₁₁ = 17
a₁₀ = 12
a₉ = 7
a₈ = 2
a₇ = -3
a₆ = -8
a₅ = -13
a₄ = -18
a₃ = -23
a₂ = - 28
a₁ = -33



a₁ = -33

hope this helps

The figure below is a diagram of a trapezoidal table that needs to be stained. Each can of stain will cover 50 square inches.
alekssr [168]

The perimeter is the sum of the outside dimensions.

b1 = 87 - 32 - 14 - 13 = 28 in.

Area = (32 + 28) /2 x 12 = 60/2 x 12 = 30 x 12 = 360 square inches.

Divide area by the amount 1 can covers:

360 / 50 = 7.2 cans, round up to 8 cans are needed.

Roman55 [17]

Answer:

310 feet per mile marker

Step-by-step explanation:

The average change will be the difference in elevation over the difference in mile markers. Randy’s elevation changed from 6220 feet to 8390 feet, which is a difference of

8390-6220=2170 feet. He started tracking at mile markers 6 to mile markers 13, which is a difference of

13-6=7 miles markers. The average change in elevation is 2170 feet / 7 mile markers = 310 feet per mile marker.
