Answer:
m = 
Step-by-step explanation:
f = 4m + 3m -1
f = 7m - 1
<em>Adding 1 to both sides</em>
f+1 = 7m
<em>Dividing both sides by 7</em>
m = 
Answer
The mean of three numbers x1,x2,x3 can be obtained by a calculus. The first step of the algorithm is
1) 
In order to obtain the median, maximun and minumun of x1, x2 and x3, we can compare x1 and x2. The smaller of those numbers will be compared to x3 and, if x3 is even smaller, then x3 is the minimun, the other small number is the median, and the remaining number is the maximun. Otherwise, we compare x3 with the bigger number to find median and maximun. To summarize:
2) compare x1 with x2. The bigger of the two numbers will be called '<em>s</em>' (for small) and the smaller will be called '<em>b</em>' (from big).
3) compare x3 with <em>s</em>. The smaller of this subset will be the minimun of the entire set of 3 elements.
4) Check if x3 is the minimun, in that case, <em>s </em>is the median, because <em>s</em> is between x3 and <em>b. </em>We also conclude that <em>b</em> is the maximun
5) if x3 in not the minimun, then compare it with <em>b.</em> The bigger element between the two of them will be the maximun of the set, and the smaller one will be the median.

Answer:
40.20cm approx
Step-by-step explanation:
Step one
given data
We are told that the dimension of a computer screen
diagonal= 52 cm
height= 33cm
Length = ?
Required
The length of the base of the screen
Step two
Let us use Pythagoras theorem to find the length of the base
Hyp^2= Opp^2+ Adj^2
52^2= 33^2+ L^2
2704= 1089+L^2
L^2= 2704-1089
L^2= 1615
L=√1615
L= 40.20cm approx
<u>The length is 40.20cm approx.</u>
Answer:

Step-by-step explanation:
The longest side is opposite the largest angle, and the shortest is opposite the smallest one.
The largest angle lies opposite the longest side, and the smallest is opposite the smallest side.
Q1.
Calculate m∠Y.
We know: Measures of angles of triangle add up to 180°.
m∠Y + m∠W + m∠X = 180°
Substitute given angles:
m∠Y + 51° + 90° = 180°
m∠Y + 141° = 180° <em>substitute 141° from both sides</em>
m∠Y = 39°
39° < 51° < 90° → XW < XY < YW
Q2.
RQ < PR < PQ → ∠P < ∠Q < ∠R
