WHAT IS THISDSSSSSSSSSSSSSSSSSSS

Mathematics

MaRussiya [10]3 years ago

Answer:

B

Step-by-step explanation:

Yes, it is. The set of rational numbers is closed for all the four operations, so x+y, x-y, x*y and x/y are rational too. And it is easy to demonstrate. A rational number can be expressed as a fraction of two integers. So, x can be expressed as a/b and y as c/d. Hence x+y = a/b + c/d = (ad+bc)/bd, which, as fraction of two integers, is rational.

54 is what percent of 24? Enter your answer in the box.
jeka94

Answer:

12.96

Step-by-step explanation:

54 percent *24

= (54/100)*24

= (54*24)/100

= 1296/100 = 12.96

Now we have: 54 percent of 24 = 12.96

Question: What is 54 percent of 24?

We need to determine 54% of 24 now and the procedure explaining it as such

Step 1: In the given case Output Value is 24.

Step 2: Let us consider the unknown value as x.

Step 3: Consider the output value of 24 = 100%.

Step 4: In the Same way, x = 54%.

Step 5: On dividing the pair of simple equations we got the equation as under

24 = 100% (1).

x = 54% (2).

(24%)/(x%) = 100/54

Step 6: Reciprocal of both the sides results in the following equation

x%/24% = 54/100

Step 7: Simplifying the above obtained equation further will tell what is 54% of 24

x = 12.96%

Therefore, 54% of 24 is 12.96

A snack food manufacturer uses 2,000 kg of peanuts to make two different snack products. Product A contains 30% peanuts by mass
GalinKa [24]

Answer: 1250 kg.

Step-by-step explanation:

Let x = mass of product A.

y=mass of product B

Then , According to the given statement , we have

0.3x+0.7y=2000-------------(1)\\\\x=3y-----------(2)

Put value of x from (2) in (1) ,we get

0.3(3y)+0.7y=2000

0.9y+0.7y=2000

1.6y=2000

y=\dfrac{2000}{1.6}=\dfrac{20000}{16}=1250

Put value of y in (2) ,we get x= 3(1250)=3750 =mass of product A

Therefore, the mass of product B =1250 kg.
