Traveling from city 1 to city 2, a pilot planned a southeast course along the path labeled d. instead, a storm forced the pilot to travel 16 miles south, then 12 miles east to reach city 2. how many extra miles was the pilot forced to fly?

8 miles

Step-by-step explanation: If we drew out the problem we would get a right triangle where d is the hypotenuse and the 16 miles south and the 12 miles east would be the legs of such a triangle. Then using the Pythagorean theorem we get:

If we then take the square root of both sides we get:

Then we realize that the pilot was forced to travel 8 extra miles because

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

subtract 15 from all parts

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make

walter needs to make at least 5 more cookies, but no more than 40 cookies; 5 ≤ x ≤ 40
