What is 10 percent of 2 3/8 in inches

Answers

Answer 1
Answer: In mathematics, the term 'of' always indicates multiplication. So we are going to multiply our percentage by the fraction to find the result.

To make this process simpler, we can start off my translating both values into decimals.
In order to change a percentage into a decimal, you can either divide the percentage by 100, or (my personal shortcut) just shift the decimal point over two places to the left.

10% = 0.1

Now, onto the fraction.
To change 2 (3)/(8) into a decimal, we simply need to set the whole number aside and then complete the fraction by dividing the numerator by the denominator.

3 / 8 = 0.375

Now, we can reattach the whole number to get our entire decimal:

2.375

From here, we can multiply these two values to get our answer:

0.1 * 2.275 = 0.2375

which is the decimal form of our answer. In order to find the fractional form, we must simply put all of the numbers to the left of the decimal point as the numerator of a fraction, with a multiple of 10 with as many zeros as there are numbers to the left of the decimal point as the denominator.

0.2375 = (2375)/(10000)

And we can reduce this fraction heavily by dividing out like terms. For the sake of time, I will eliminate this step to tell you that the finished reduction shows us a fraction of (19)/(80).

So there you have it.
10% of 2 (3)/(8) is 0.2375 or (19)/(80).
Hope that helped! =)

The sum of the ages of Arturo, Benny, and Carlos is 41 years. Twice Arturo's age exceeds the sum of Benny and Carlos's ages by one year. Five years ago, Benny was 2 years more than twice as old as Carlos. Find their ages now

Answers

Answer: Arturo is 14 years

Benny is 17 years

Carlos is 10 years

Step-by-step explanation:

Let x represent the age of Arturo.

Let y represent the age of Benny.

Let z represent the age of Carlos.

The sum of the ages of Arturo, Benny, and Carlos is 41 years. It means that

x + y + z = 41- - - - - - - - - - - - -1

Twice Arturo's age exceeds the sum of Benny and Carlos's ages by one year. It means that

2x = y + z + 1- - - - - - - - - 2

Five years ago, Benny was 2 years more than twice as old as Carlos. It means that

y - 5 = 2(z - 5) + 2

y - 5 = 2z - 10 + 2

y = 2z - 8 + 5

y = 2z - 3

Substituting y = 2z - 3 into equation 2, it becomes

2x = 2z - 3 + z + 1

2x = 2z + z - 3 + 1

2x = 3z - 2

x = 3z/2 - 1

Substituting y = 2z - 3 and

x = 3z/2 - 1 into equation 1, it becomes

3z/2 - 1 + 2z - 3 + z = 41

Multiplying through by 2, it becomes

3z - 2 + 4z - 6 + 2z = 82

3z + 4z + 2z - 2 - 6 = 82

9z - 8 = 82

9z = 82 + 8 = 90

z = 90/9

z = 10

x = 3z/2 - 1 = (3 × 10)/2 - 1

x = 14

y = 2z - 3 = 2 × 10 - 3

y = 17

The graph of f (x)=√x is transformed to create thegraph of g (x)= -2√x+6. Which of these describes a
transformation used to create the graph of g?

Answers

The transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.

The "-2" in the equation of g(x) reflects a vertical stretch by a factor of 2, which causes the graph to become narrower and steeper than f(x).

The "+6" in the equation of g(x) reflects a vertical shift upward by 6 units, which moves the entire graph of g(x) upward by 6 units.

Therefore, the transformation used to create the graph of g(x) from the graph of f(x) is a vertical and horizontal transformation.
