Answer: The maximum length of a toothpick that still fits the box is
Explanation: the longest straight distance within a rectangular box (prism) is its diagonal (in three dimensions), i.e., the path from one corner to its diagonally opposite corner.
The diagonal length in a two-dimensional rectangle can be calculated using the Pythagorean Theorem. There is a three-dimensional analog of that theorem for prisms. Let a,b,c be the sides of the prism. Then the following holds for the diagonal length d:
In order to answer the question we determine the length d:
Answer:
the range of the relation is 3
Answer:
Question 1: 0.38, 3/8, 25%
Question 2: 72oz.
Question 3: 165
Step-by-step explanation:
First Question: We can make all the numbers to decimals. 25%= 0.25, 3/8= 0.375, and 0.38 is given. Then we can clearly see that 0.38, 3/8, 25% is the order.
Second Question: There are 16oz. in a pound, so we have to multiply 4.5 and 16. 4.5*16 = 72. There are 72 oz. in 4.5lbs.
Third Question: We just have to plug 5 in, so 7(5)^2 - 10 is our equation. Following the order of equations, we have the exponent first. 5^2 is 25. We end up with 7(25) - 10. Then we have to multiply, so 7*25 = 175. Finally we have 175 - 10 which is 165.
