65.5 is the answer. You could get it by adding the two numbers and dividing the sum by 2.
65.5
5.45 is the number between 4.5 and 5.5
77 is one possibility.
The percentage of girls started at 77% and dropped to 54% with no boys leaving. As the total number of students was 100, 54% means there are 54 girls still there. As 77 minus 54 is 23, that is how many girls left. N=23.
54 is 70.13% of 77.
54 doesn't go evenly into 77. 54 goes into 77 once with a remainder of 23.
54 protons, an average of 77 neutrons, and 54 electrons.
The atomic number of an element is the number of protons in its nucleus. Always. The mass number of an atom is the number of protons plus the number of neutrons in it. And that means an isotope of element 54 (xenon) that has 77 neutrons in its nucleus has a mass number of 54 + 77 or 131, and you'll have an atom of 131Xe. A link can be found below.
the real numbers between 66 and 77 are (66,67,68,69,70,71,72,73,74,75,76,77)
The GCF is 1.
(-54) - 23 = -77
78 - 89 are the numbers that come between 77 and 90.
