The perimeter of a school gym is 522 feet. The gym measures 80 feet wide. Determine the length of the school. PLEASE EXPLAIN THE

lidiya [134]

Total perimeter is 522 ft. I will guess the gym is a big rectangle.

Therefore, Perimeter of a rectangle = 2L + 2W
P= 2L+ 2W

We know 80 ft wide. so now we plug and chug the equation we came up with

P=522 ft
P=2L+ 2(80)

522=2L+ 160

L= 181

Which of the following represents the general term for the sequence 1, 3, 5, 7, 9, . . .? n

zalisa [80]

Answer:

Step-by-step explanation:

In the given sequence, the terms are increasing in arithmetic progression. The common difference, d between successive terms is 2

The formula for determining the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

a represents the first term of the sequence.

d represents the common difference.

n represents the number of terms in the sequence.

From the information given,

a = 1

d = 2

Therefore, the expression for the general term for the sequence is

Tn = 1 + 2(n - 1)
