Answer:

1kg ghee is left behind

Step-by-step explanation:

Here, we are to calculate the amount of ghee left.

Firstly, 2/4 was consumed for preparing medicine. This is same as 1/2

The amount used in preparing medicine is thus 1/2 * 20kg = 10kg

amount remaining = 20kg - 10kg = 10kg

She also use 2/5 and 1/2 of the remainder.

The total amount used is 2/5 + 1/2 = 9/10

The amount used is thus 9/10 * 10 = 9kg

what is left is thus 10kg -9kg = 1 kg

1. Three apples, a, and two peaches, p, sell for $1.25.
Simora [160]

Answer:

$0.25

Step-by-step explanation:

You can use systems of equations to solve this.

3a+2p = 1.25

5a+p = 1.5

Multiply the second equation by 2.

3a+2p = 1.25

10a+2p = 3

Subtract the bottom from the top

-7a= -1.75

Divide by -7

a= 0.25

Each apple is $0.25 (in this case, the peach also costs $0.25)

Determine if the graph is symmetric about the x-axis, the y-axis, or the origin. r = 5 cos 3θ
Aneli [31]
First of all get a picture of what this looks like. Desmos is a pretty good graphing program, but anything that will do polar coordinates will work. 

Here is the graph.

What you can see is that this graph is symmetrical around the x axis.

When you talk about symmetry, you can think of it as taking a mirror and putting it where you think there is symmetry. If you can't tell the difference between the image and the real thing, then you have symmetry.

In this case, the mirror will show symmetry along the x axis and no where else.
