26,500 - 19,610 = 6,890
6,890 would be your price discount, but now you'd have to find your percent discount. Make it into an equation to make things easier.
6,890/26,500 = p/100
(6,890*100)/26,500 = p
6,890*100 = 689,000
689,000/26,500 = 26
The price discount would be 26%.
2^-2 would become 1/2^2 which becomes 1/4.
Answer:
(a) LM=12 units, LN=35 units, MN=37 units
(b)8 84 units
(c) 210 square units
Step-by-step explanation:
(a)
Since points L and M have same x coordinates, it means they are in the same plane. Also, since the Y coordinates of L and N are same, they also lie in the same plane
Length 
Length 
Length
Alternatively, since this is a right angle triangle, length MN is found using Pythagoras theorem where

Therefore, the lengths LM=12 units, LN=35 units and MN=37 units
(b)
Perimeter is the distance all round the figure
P=LM+LN+MN=12 units+35 units+37 units=84 units
(c)
Area of a triangle is given by 0.5bh where b is base and h is height, in this case, b is LN=35 units and h=LM which is 12 units
Therefore, A=0.5*12*35= 210 square units

Answer:

Step-by-step explanation:
Given





Required
Probability of selecting a yellow then orange rock
From the question, we understand that the probability is that of without replacement.
Since the yellow, is first picked.
We need to determine the probability of picking a yellow rock, first.



The rock has reduced by 1;
Next is to determine the probability of picking an orange rock



The required probability is calculated as thus:
