Answer:
16 is correct
Step-by-step explanation:
<span>The length is:
the square root of [ (the difference in 'x' values)² + (the difference in 'y' values)² ]
D = √ [ (-2-6)² + (5-2)² ]
= √ [ (-8)² + (3)² ]
= √ (64 + 9) = √75 = 5√3 = <u>8.66</u> (rounded to 3 sig-figs)</span>
Answer:
100 + 100 + 25 + 25 + 13 + 13 + 9
Step-by-step explanation:
There are 334 ways to do it. The answer shown above is shortest sum. Perhaps the longest is 6×9 + 33×7, for a total of 6 + 33 = 39 numbers.
_____
Given the above sum, certain replacements can be made:
13 + 13 + 9 = 7 + 7 + 7 + 7 + 7
25 = 9 + 9 + 7
25 + 25 = 13 + 9 + 7 + 7 + 7 + 7
25 + 25 + 25 = 13 + 13 + 13 + 9 + 9 + 9 + 9
100 = 25 + 25 + 25 + 25
These can be iterated to whatever depth or combination may tickle your fancy.
Answer:
D
x=5*sqrt(2)/2
Step-by-step explanation:
since it is a right triangle, and one of the other angles is 45, we know that the last angle must also be 45 since the 3 interior angles must be 180
then using pythagroem theorem
sqrt(a^2+b^2)=c
sqrt(x^2+x^2) = 5
square both sides
x^2+x^2=25
2x^2=25
x^2=25/2
square root both sides
x= sqrt(25/2)=5/sqrt(2)
rationalize the demonominator by multiplying by sqrt(2)/sqrt(2)
x=5*sqrt(2)/2
