A tin contains 20kg of ghee. Rao consumed 2⁄4 of it for preparing medicines. From the remaining ghee Rao used 2⁄5 and 1/2 of it

Alik [6]

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

Ten pounds of mixed birdseed sells for 8.24 per pound. The mixture is obtained from two kinds of birdseed, with one variety pric

Kipish [7]

Answer:

2 pounds of 1st kind and 8 pounds of 2nd kind are mixed.

Explanation:

Given:

Ten pounds of mixed birdseed sells for 8.24 per pound.

Price of the 1st variety of birdseed=5.68 per pound

Price of the 2nd variety of the birdseed=8.88 per pound.

To find :

Pounds of 1st variety of birdseed are used in the mixture=?

Pounds of 2ndvariety of birdseed are used in the mixture=?

Solution:

Let the weight of 1st kind added in mixture be n pounds.

Then weight of 2nd kind will be 10 – n pounds.

Now, total cost of mixture = cost of 1st kind birdseed + cost of 2nd kind birdseed

Weight of mixture x cost per pound = weight of 1st kind x cost per pound + weight of 2nd kind x cost per pound.

Substituting the values,

$10\times8.24 = n\times5.68 + (10-n)\times8.88$

82.4 = 5.68n + 88.8 – 8.88n

8.88n – 5.68n = 88.8 – 82.4

3.2n = 6.4

$n = \frac{3.2}{6.4}$

n = 2

Then, weight of 2nd kind is 10 – 2 = 8 pounds.

Hence, 2 pounds of 1st kind and 8 pounds of 2nd kind are mixed.

How do you factorise xy zy?

alexandr1967 [171]

Assuming you meant to write: "xy + zy"
The answer is: xy + zy = y(x + z)
The one variable that appear multiple times is: "y". There are no coefficients (other than the implied coefficients of "1"; since "1" multiplied by any number equals that very number). Since "y" appears twice, we can "factor out" a "y" ; as follows:
________________
y(x+z).
____________________
Take note of the distributive property of multiplication:
_____________________
a(b+c) = ab + ac ;
_________________
AND: a(b-c) = ab - ac.
____________________
Likewise: y(x+z) = yx +yz
= xy zy
