Answer:
Let x = the third side
In a triangle, the sum of any 2 sides must be larger than the third side.
I believe this is called the triangle inequality theorem.
We can construct 3 inequalities to obtain the range of values for the third side.
(Inequality #1) 12 + 4 > x
16 > x
(Inequality#2) 12 + x > 4
x > -8 (we can discard this ... we know all sides will be positive)
(Inequality #3) 4 + x > 12
x > 8
So when we combine these together,
8 < x < 16
X (the third side) must be a number between 8 and 16. but not including 8 and 16
Step-by-step explanation:
time ∝ number of door 1
time . ∝ 1/number of people. 2
compare equation 1 and 2
time . ∝ number of door / number of people
put k as constant
time = k number of door / number of people. 3
time =2. people=4 door = 10
putting in equation 3
2 = k (10)/(4)
2×4/10 = k
8/10 =k
4/5 =k
putting in equation 3
time= 4/5 number of door / number of people
now time =5 door= 25 people=?
5=4/5 (5)/ (number of people)
number of people =4/5 ×25/5
number of people= 4
Answer:
The would be 69.23%
Step-by-step explanation:
27:39*100 =
(27*100):39 =
2700:39 = 69.23
hope that helps
Of course ! An expression is <u>always</u> equal to itself.
But if there's, say, an 'x' in the expression, then such an equation would be true
for x=every possible number. You might say it has an infinite number of solutions ...
which certainly has to be true, because no matter what you do to an expression,
it's still always equal to itself !
