Imagine you lay the 9 and 6 logs side by side. The 6 is 3 feet short of the 9.
This rules out two as it is 1 foot short.
3 is also ruled out as there would be no dimension to the flower bed - it would be impossible to make a triangle.
Now do the reverse - use on of the remaining logs to test if they would work.
Try 15; 9 + 6 = 15 but we're looking to make a larger number
9 + 6 = 15 > 13 feet
The only log it can be is C 13 feet.
Answer:
2 → 3 → 1 → 4
Step-by-step explanation:
We are given the list of cost of fabric in dollars per square yard.
So, the total cost per square yard of different fabric are:
1. 6.5 for $6.25 = = 0.96
2. 4 for $3 = = 0.75
3. 8.5 for $8.10 = = 0.95
4. 6 for $7.20 = = 1.2
Since, 0.75 < 0.95 < 0.96 < 1.2
Hence, from least to the greatest unit cost, the sequence is 2 → 3 → 1 → 4.
Answer:
x = 11
Step-by-step explanation:
2x + 16 = 5x - 17
+ 17 + 17
2x + 33 = 5x
- 2x - 2x
33 + 3x
33/3 = 11
3x/3 = x
The most famous impossible problem from Greek Antiquity is doubling the cube. The problem is to construct a cube whose volume is double that of a given one. It is often denoted to as the Delian problem due to a myth that the Delians had look up Plato on the subject. In another form, the story proclaims that the Athenians in 430 B.C. consulted the oracle at Delos in the hope to break the plague devastating their country. They were advised by Apollo to double his altar that had the form of a cube. As an effect of several failed attempts to satisfy the god, the plague only got worse and at the end they turned to Plato for advice. (According to Rouse Ball and Coxeter, p 340, an Arab variant asserts that the plague had wrecked between the children of Israel but the name of Apollo had been discreetly gone astray.) According to a message from the mathematician Eratosthenes to King Ptolemy of Egypt, Euripides mentioned the Delian problem in one of his (now lost) tragedies. The other three antiquity are: angle trisection, squaring a circle, and constructing a regular heptagon.
