Raj made this argument: The Triangle Inequality Theorem states that if the lengths of three sides of a triangle are a, b, and c, then a + b > c. For this reason, since a, b, and c are all positive numbers, the square of a + b must be greater than the square of c. However, for a right triangle, the Pythagorean Theorem states that if the lengths of the legs are a and b, and if the length of the hypotenuse is c, then a2 + b2 = c2, not a2 + b2 > c2. Therefore, since the Pythagorean Theorem is known to be correct, and since right triangles should adhere to the Triangle Inequality Theorem, the Triangle Inequality Theorem must be incorrect. What is wrong with Raj’s argument?

Take a look at the streets in Phoenix. N 9th Avenue, N 10th Avenue, N 11th Avenue, N 12th Avenue, and N 13th Avenue are parallel, and they intersect W Roosevelt Street and Phoenix-Wickenburg Hwy. The distance between N 15th Ave. and N 13th Ave., represented by segment AB, is 530 feet along W Roosevelt St. The distances between N 13th Ave. and N 12th Ave. (segment BC), between N 12th Ave. and N 11th Ave. (segment CD), between N 11th Ave. and N 10th Ave. (segment DE) and between N 10th Ave. and N 9th Ave. (segment EF) are all the same, 340 feet. Now let's find some distances between these avenues along Phoenix-Wickenburg Hwy. (segment AL).If the distance on Phoenix-Wickenburg Hwy between 13th Avenue and 11th Avenue, represented by segment GJ is approximately 1060 feet, how long is Phoenix-Wickenburg Hwy. between 13th Avenue and 15th Avenue (segment AG) to the nearest foot?1652 feet826 feet340 feet530 feet

Lynn takes her puppy, Olive, to a doggy daycare. The price for the daycare is $21 per day along with a monthly admission fee of $48. Last month Lynn paid a total of $426. Which equation can be used to find the number of days, d, that Olive spent at daycare, and how many days was she there? 48d + 426 = 21; 9 days 21d + 48 = 426; 18 days 48d + 21 = 426; 8 days 426d - 21 = 48; 7 days NextReset
