Answer:
We can't even see the whole questions so how do you expect us to awnser it when we can't even see the full questions
Decimal i know this because of the dot also known as a decimal
We have two equations
One to for the total number of units, to distinct them from 1 bedroom units or 2 bedroom units
x- one bedroom units
y- two bedroom units
x+y= 100
495x+600y= 55,275
We can try to plug in these values for y since it’s asks “how many two bedroom apartments are there” and see if it works out
495x+600(45)= 55,275
495x+27000=55275
-27000 -27000
495x= 28275
/495 /495
x=57.12
There can’t be 57.12 units so A is wrong
495x+600(55)= 55,275
495x+ 33000= 55275
-33000 -33000
495x =22275
/495 /495
x=45
This could work so B is the answer , you could go ahead and try C and B but most likely the answer is B
Answer:
x = 60°
y = 50°
Step-by-step explanation:
✅x = 180° - (50° + 70°) (sum of interior angles of a triangle theorem)
x = 180° - 120°
x = 60°
✅Based on the exterior angle theorem, the sum of the opposite interior angles of a triangle = the exterior angle.
Therefore,
50° + 60° = x + y
Plug in the value of x
50° + 60° = 60° + y
110° = 60° + y
y = 110° - 60°
y = 50°
Answer:
Conjecture : 2xy / ( x + y ) ≤ √xy
Step-by-step explanation:
Harmonic mean of x and y = 2xy/( x + y )
<u>Formulate a conjecture about their relative sizes </u>
we will achieve this by computing harmonic and geometric means
Geometric mean = √xy
harmonic mean = 2xy/( x + y )
Conjecture : 2xy / ( x + y ) ≤ √xy
attached below is the proof
