Answer:
Hello,
Step-by-step explanation:
One other way:
Let say x=1.272727...
100x=127.272727...
x=1.272727...
99x=126
x=126/99
<u>x=14/11</u>
Answer: 54 cm
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Perimeter of a square = side length x4
Replacing with the values given:
72 = 4 s
Solving for s (side length)
72/4=s
s = 18 cm
Since the side length of the square is the length of each rod, and all the rods have the same length, to obtain the perimeter of the triangle we have to apply:
Perimeter of an equilateral triangle: 3 side length
P = 3 (18 ) = 54 cm

Answer:
Correct choices are 1 and 4
Step-by-step explanation:
As per data given we have:
- Median temperature is 75°F and 88°F
- And the range from the median is 5° for both cities
This gives us lowest temperatures of:
- 75° -5° = 70° and 88° - 5°= 83° respectively
And high temperatures are:
- 75° + 5° = 80° and 88° + 5° = 93°
<u>Answer choices based on above details:</u>
- Choice 1 - correct
- Choice 2 - incorrect. Correct answer is 93°
- Choice 3 - incorrect. Correct answer is 93° - 70° = 23°
- Choice 4 - correct
