IN A CLASS OF 30 STUDENTS 13 OF THEM ARE BOYS WHAT PERCENTAGE ARE GIRLS?

mestny [16]

Class of students - number of students that are boys = numbers of students that are girls

30 - 13 = 17

To change the number of students that are girls into percentage...

17/1 * 1/100 = 17/100

17/100 in a % form = 17%

The percentage of girls in the class is 17%

Factor each expression 30+10x-40y

Sergio039 [100]

Hello!

To factor you find the biggest number they can be divided by

The biggest number that all the number can be divided by is 10

You put that outside parenthesis

10()

Divide the expression by 10

3 + x - 4y

Put the two together

10(3 + x + 4y)

Hope this helps!

Line bc is represented by 3x+2y=8 line ad is represented by -3x-2y=6 what is the relationship of line bc to line ad explain the

Bas_tet [7]

Answer:

The answer is below

Step-by-step explanation:

The equation of a straight line is given by:

y = mx + b

where m is the slope of the line and b is the y intercept (value of y when x = 0).

Given the equation of two lines as $y=m_1x+b_1\ and\ y=m_2x+b_2$ , the two lines are parallel to each other if $m_1=m_2$ . Also the lines are perpendicular if

$m_1m_2=-1$

Given line BC:

3x + 2y = 8

2y = -3x + 8

y = -3x/2 + 4

Hence the slope of the line BC = -3/2

For line AD:

-3x - 2y = 6

-2y =3x + 6

y = -3x/2 - 3

Hence the slope of line AD is -3/2

Since both line BC and AD have equal slope (-3/2), hence both lines are parallel to each other
