Weegy: Jeremy is building a large deck for a community center. The deck is shaped as a rectangle. The width of the deck is 29 feet. The perimeter of the deck is to be at least 134 feet. P=2(L+W); 134=2(L+29); 134=2L+58; 2L=76; L=76/2; L=38. [ The length of the deck is 38 feet. ] User: Caitlin had $402 in her bank account. She withdrew $15 each week to pay for a swimming lesson. She now has $237.
Write an equation that can be used to find the number of swimming lessons that she paid for.
Weegy: 15x+237=402 15x=165 x=165/15 x=11 She paid for 11 swimming lessons. 237/19 = 12.47 She can pay for 12 lessons at $19 per lesson with her remaining $237. User: . Is a triangle with sides of length 6 ft., 21 ft., 23 ft. a right triangle? Explain Weegy: It is not a right triangle. For a triangle to be right angled,it has to obey Pythagoras Theorem. 12^2 + 14^2 = 19^2. So, 144 + 196 = 361
340 = 361. It's not a right triangle. User: Is the sequence 5, 9, 15, ... an arithmetic sequence? Explain. Weegy: A sequence such as 1, 5, 9, 13, 17 or 12, 7, 2, ?3, ?8, ?13, ?18 which has a constant difference between terms. The first term is a1, the common difference is d, and the number of terms is n.
