if the sum of the first 60 positive integers is s, what is the sum of the first 120 integers in terms of s? a. 2s 3600 b. s^2 36
natima [27]
For the first 60 positive integers, a = 1, n = 60, l = 60.
Sn = n/2(a + l)
s = 60/2(1 + 60) = 30(61)

For the next 60 positive integer, a = 61, n = 60, l = 120
Sum = 60/2(61 + 120) = 30(61 + 120) = 30(61) + 30(120) = s + 3600

Sum of first 120 positive integers = s + s + 3600 = 2s + 3600

Mr. Williams is painting only the back of his barn. A gallon of paint covers 70 square feet. How many square feet will Mr. Willi
Alex17521 [72]

Answer:

Option A. 264 ft² ; 4 gallons

Step-by-step explanation:

Given question is incomplete; find the complete question in the attachment.

From the picture attached,

Area of the barn to be painted = Area of the (rectangular base + Triangular top) - Area of the window

Area of the rectangular base = 12 × 18

                                                = 216 ft²

Area of the triangular top = \frac{1}{2}(\text{Base}\times \text{Height})

                                          = \frac{1}{2}(12)(28-18)

                                          = 60 square feet

Area of the window = 3 ft × 4 ft

                                 = 12 ft²

Total area to be painted = 216 + 60 - 12

                                         = 264 ft²

∵ 70 square feet of the barn is covered by the amount of paint = 1 gallon

∴ 1 square feet will be covered by the amount = \frac{1}{70} gallons

∴ 264 square feet will be painted by = \frac{264}{70}

                                                             = 3.77 gallons

                                                             ≈ 4 gallons

Therefore, Option (A). 264 ft²; 4 gallons will be the answer.

What does it mean if am equation is equivalent to 0=0? explain.
anzhelika [568]

This means it has infinite solutions congrats. When solving algebraic equations you can find one solution, no solutions. When you have infinite solutions that means that equations has multiple things that can equal it.
