MATHEMATICS MIDDLE SCHOOL

n 2010, the ratio of boys to girls in the top 10 percent of their class at Bixby High School was 3 to 5. In 2011, the number of boys increased by 6 and the number of girls increased by 2. If the new ratio of boys to girls is 2 to 3, write an expression that represents how many students were in the top 10% in 2010.

Answers

Answer 1

Answer:

Answer: Total number of students will be 112.

Step-by-step explanation:

Since we have given that

The ratio of boys to girls in the top 10% of their class at Bixby High School was

$3:5$

So, Let the number of boys be 3x

Let the number of girls be 5x

According to question,

$(3x+6)/(5x+2)=(2)/(3)\n\n3(3x+6)=2(5x+2)\n\n9x+18=10x+4\n\n18-4=10x-9x\n\n14=x$

So, total number of students will be

$3x+5x=8x\n\n8* 14=112$

Hence, Total number of students will be 112.

What Is The Slope-Intercept Form Of This Equation 3x+9y=18

Answers

Y= -1/3x+2 because The Change in x and the change in y come out to -1/3x then you plug in the coordinates and solve for b. Hope i helped

Answer:

Solve the given equation for y to obtain the slope and y-intercept of this equation: -3x + 9y = 18

Add 3x to both sides: 3x - 3x + 9y = 18 + 3x

Simplifying, 9y = 3x + 18

Dividing both sides by 9 to solve for y:

y = (3/9)x + 2 or (after reduction) y = (1/3)x + 2

The slope is 1/3 and the y-int. is (0,2).

The table shows the number of Salvador has read. Find the ratio of mystery books to the total. Explain it's meaning.(look at the picture of the table)

Answers

$Total:\n\n10+7+5+2=24\n\nRatio:\n\n10:24\ ->5:12\n\nThe\ ratio\ is\ 5:12$

Final answer:

To find the ratio of mystery books to the total, divide the number of mystery books by the total number of books and simplify the ratio if possible.

Explanation:

To find the ratio of mystery books to the total, we need to divide the number of mystery books by the total number of books and simplify the ratio if possible.

In this case, the number of mystery books is 12 and the total number of books is 48. So, the ratio of mystery books to the total is 12:48.

We can simplify this ratio by dividing both the numerator and denominator by 12. This gives us a simplified ratio of 1:4.
