The price of fruits per kg are given below- Watermelon Rs 18.50 Cherry Rs 72 Grapes Rs 120.60 Apples Rs 78.40 Karan bought 412 k
Papessa [141]

Answer:

X=-2.74*10^{-7}Rs

Step-by-step explanation:

From the question we are told that:

Table for price per Kg

 Watermelon Rs 18.50

 Cherry Rs 72

 Grapes Rs 120.60

 Apples Rs 78.40

Karan Bought:

 412 kg watermelon

 1 kg 200g cherries

 250 g grapes

 134 kg apples

Generally the equation for Total Price of Fruits Bought is mathematically given by

\sum (Price Rs* Weight kg )

 \sum (P* W)=(412*18.5)+(1.2*72)+(0.25*120.60+(134*78.40))

 \sum (P* W)=27374289.78

Therefore the Amount of Money he gets back is

 X=500-\sum (P* W)

 X=-2.74*10^{-7}Rs

Therefore

He owes the shop keeper 2.74 million Rs

Hint: If Angle XYZ (Exterior Angle Y) is 115, then Angle XYW (Interior Angle Y) must be 65 since they are supplementary angles.
RUDIKE [14]
Since all angles in a triangle are equal to 180 and you already have two angles you just have to subtract.
So, 180-(65 + 45)
Simplify = 180- 110
Equals = 70

What is the slope and y-intercept of the equation 3 (y-2)+6 (x+1)-2=0
elena-s [515]
<span>Answer: Slope = -4.000/2.000 = -2.000   x-intercept = 2/6 = 1/3 = 0.33333 <span>   y-intercept = 2/3 = 0.66667


What I'm trying to show in the graph is:
</span></span>
y tells us how far up the line goes.........
x tells us how far along...........
m is the Slope or Gradient i.e. how steep the line is.........
b is the Y-intercept i.e. where the line crosses the Y axis.......

I really hope this helps ^-^
