in a school 46% of the 300 students are boys. how many girls are in the class than boy?

Answers

Answer:

138 of the students are boys, and 162 of them are girls. there are 24 more girls than boys.

Step-by-step explanation:

multiplying a number by its percent as a decimal gets you the percent of that number

300 x .46 = 138 boys

now subtract that from the original 300 to get the girls

300 - 138 = 162 girls

lastly subtract the girls from the boys to get how many more girls there are than boys

162 - 138 = 24

You can multiply -2.2 by 6.2 to find the total variation in water level. What decimal represents the total variation in water level that Ericka observed?

Answers

Answer:

-13.64

Step-by-step explanation:

no explanation needed. Hope this really helps! :):) :) :) :)

13.64 decimal represents the total variation in water level that Ericka observed.

What are mathematical operations?

The term "operation" in mathematics refers to the process of computing a value utilizing operands and a math operator. For the specified operands or integers, the math operator's symbol has predetermined rules that must be followed. In mathematics, there are five basic operations: addition, subtraction, multiplication, division, and modular forms.

Given, You can multiply -2.2 by 6.2 to find the total variation in water level.

Since it is already given that the multiple of -2.2 and 6.2 will give the total variation of water level.

Thus, the decimal represents the total variation in water level that Ericka observed = -2.2 * 6.2

the decimal represents the total variation in water level that Ericka observed = 13.64

therefore, the decimal represents the total variation in water level that Ericka observed is 13.64.

What is the definition of no solution?

Answers

Answer:

No solution would mean that there is no answer to the equation.

Step-by-step explanation:

It is impossible for the equation to be true no matter what value we assign to the variable. Infinite solutions would mean that any value for the variable would make the equation true.

There is no answer to that problem. There is either a critical error in the problem, or it's just impossible to calculate. For example, x/0 is literally nothing. You can't solve it.

Solve the proportion.

5/6 = 10/x÷1

x = ?

Answers

Given expression:

                    [tex]\frac{5}{6}[/tex]   = [tex]\frac{10}{x /1}[/tex]

Find x;

    To find x, let us first cross multiply;

       5 x (X /1)  = 6 x 10

  We know that any number divided by 1 will give back that same number; so the value of the expression in the parentheses is x

        5 x X   = 60;

So, divide both sides by 5 to give the value of X;

       X  = [tex]\frac{60}{5}[/tex]   = 12

The value of X is 12
