in the six grade 54% of the are boys. there are 189 boys in the sixth grade. what is the total number of the students in sixth g

notka56 [123]

<h2>189 boys is 54%</h2><h2>x is 46%(100-54)</h2><h2>Cross multiply:</h2><h2>189*46%=54%*x</h2><h2>86.94=0.54x</h2><h2>x=161</h2><h2>189 boys 161 girls</h2><h2>350 altogether</h2><h2>Hope this helps plz hit the crown :D</h2>

Answer:

1 = 40

2 = 140

3 = 40

4 = 140

5 = 40

6 = 140

7 = 40

Step-by-step explanation:

A straight line is 180 so I did 40 because 140 + 40 = 180. once I figured 3 out I basically had the rest.

Write the slope-intercept form of the equation of the line described.

Ad libitum [116K]

Given the line

$y=-x+2$

We know that the slope-intercept form of the line equation is

$y=mx+b$

here

m is the slope and b is the intercept

Thus, the slope = -1

We know that the parallel lines have the same. Thus, the slope of the parallel line is: -1

Using point-slope of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = -1 and the point (4, 0)

$y-0 = -1 (x-4)$

Writing in the slope-intercept form

$y = -x+4$

Thus, the slope-intercept form of the equation of the line equation parallel to y=-x+ 2 will be:

$y = -x+4$

<em>Note: </em><em>Your line is a little bit unclear. But, I am assuming the</em>

<em>ine is: </em>y = -x-1

<em />

Given the assumed line

y = -x-1

We know that the slope-intercept form of the line equation is

$y=mx+b$

here

m is the slope and b is the intercept

Thus, the slope = m = -1

We know that a line perpendicular to another line contains a slope that is the negative reciprocal of the slope of the other line, such as:

slope = m = -1

perpendicular slope = – 1/m = -1/-1 = 1

Using point-slope of the line equation

$y-y_1=m\left(x-x_1\right)$

substituting the values m = 1 and the point (4, 3)

$y - 3 = 1 (x-4)$

Writing in the slope-intercept form

y-3 = x-4

y = x-4+3

y = x - 1

Thus, the slope-intercept form of the equation of the line equation perpendicular to y = -x-1 will be:

y = x - 1

Divide 3 over 4 ÷ 1 over 8 = ____.

hammer [34]

When you divide two fractions, you actually just flip one over (it's reciprocal) and multiply them.

$\frac{3}{4}$ ÷ $\frac{1}{8}$ Use the recriprocal of $\frac{1}{8}$
<span> $\frac{3}{4}$ ÷ $\frac{8}{1}$ Multiply (3 x 8) and (4 x 1)
</span>
$\frac{24}{4}$ Divide

6

<span> $\frac{3}{4}$ ÷ $\frac{1}{8}$ = 6</span>
