Answer:

Answer:

114/430 not that hard

Step-by-step explanation:

Therefore he took 40 gram of $1^(st)$ type solution and 10 gram of $2^(nd)$ type solution.

Step-by-step explanation:

Giventhat , A pharmacist 13% alcohol solution another 18% alcohol solution .

Let he took x gram solution of $1^(st)$ type solution

and he took (50-x) gram of $2^(nd)$ type solution.

Total amount of alcohol = $[x*(13)/(100)] +[(50 -x) *(18)/(100) ]$ gram

Total amount of solution = 50 gram

According to problem

⇔ $( [x*(13)/(100)] +[(50 -x) *(18)/(100) ])/(50)= (14)/(100)$

⇔ $(13x +900-18x)/(100*50) =(14)/(100)$

⇔- 5x= 700 - 900

⇔5x = 200

⇔x = 40 gram

Therefore he took 40 gram of $1^(st)$ type solution and (50 -40)gram = 10 gram of $2^(nd)$ type solution.

A pig weighs 9.8 pounds. Convert the pigs weight to ounces

Answers

Answer: 156.8 ounces

Step-by-step explanation:

We have given that the weight of a pig = 9.8 pounds

Since , we know that 1 pound = 16 ounces

Therefore, to convert 9.8 pounds to ounces , we need to multiply it with 16, we get,

$\text{ 9.8 pounds}=9.8*16\n\n\Rightarrow\text{ 9.8 pounds}=156.8\text{ ounces}$

Hence, the weight of pig = 156.8 ounces

The pig's weight is 156.8 ounces.

Further Explanation

Given:

A pig's weight is 9.8 pounds

Convert this pig's weight to ounces!

Let's say the pig's weight in ounces is in variable x, so :

$\boxed { 1 pounds = 16 ounces }\n\boxed {(16 ounces)/(1 pounds) = (x ounces)/( 9.8 pounds) } \n \boxed {x=(16 ounces *\ 9.8 pounds)/(1 pounds) } \n \boxed {x=156.8 ounces }$

From the equation above, we can conclude that in converting unit of measurement, we can use this three steps:

write the conversion in fraction
multiply
cancel any unit that are both top and bottom

Multiplying decimal numbers is the same way as the whole numbers except, you have to remember where to put the decimal point. Here is the explanation using the standard algorithm method:

9.8 ⇒ has 1 decimal point

16 x ⇒ has 0 decimal point

588

98 +

156.8 ⇒ has 1 decimal point

a 12-pounded bag of dog food costs $12.36. a 15-pounded bag of cat food cost $15.30. which is a better deal???

Answers

The 15 pound of cat food because if you divide 15.30 by 15 it gives you 1.02 which is the price per pound.
For the dog food you would divide 12.36 by 12 to get 1.3.
The price per pound for the cat food is cheeper the the dog food which means you get more food at a lower cost.

Hope this helps!

15 pounded because when you divide is cheaper
