Answer:
The correct answer is 30 miles.
Step-by-step explanation:
Porter is driving due east to point, say B, from his initial point, say A, for about 20 miles. Therefore AB = 20 miles.
He is driving due south to point, say C, from B, for about 23 miles. Therefore BC = 23 miles.
Therefore the distance between A and C is given by the Pythagoras theorem,
![AC^{2} = AB^{2} + BC^{2}](https://tex.z-dn.net/?f=AC%5E%7B2%7D%20%3D%20AB%5E%7B2%7D%20%2B%20BC%5E%7B2%7D)
⇒ AC =
=
= 30.479 miles ≈ 30 miles.
Therefore Porter is 30 miles away from his initial point, to the nearest hundredth of a mile.
Answer:
The closest I can get is 8b
Step-by-step explanation:
Since we don't know what b is, you have to have 8b
Answer:
x=24 square feet per hour
Step-by-step explanation:
You divide 16 by 2 to get how many tiles that are laid in 1/3 of an hour. Then multiply that by 3 to get how many tiles in one whole hour. The answer should be 24.
I believe that the answer is D) all real numbers.
Answer:
Step-by-step explanation:
The cost of another 3 panes of glass would be
Solution:
Given, Number of panes of glass bought = 8
Cost of 8 panes of glass =
Number of broken panes of glass = 3
We have to find the cost of 3 panes of glass
By unitary method, If 8 panes of glass costs , then the cost of one pane of glass will be as follows,
Therefore, for 3 panes of glass it would be
Unitary method:
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value. In essence, this method is used to find the value of a unit from the value of a multiple, and hence the value of a multiple.
