the ratio of boys to girls in a homeroom at berkmar middle school is 3;4 if there are 12 boys how many girls are in homeroom
REY [17]

Answer:

16 girls

Step-by-step explanation:

If you have 12 boys, and the ratio is 3;4, that means you multiplied 3 times 4. To find the answer to this problem, you need to multiply 4 by 4 because you multiplied 3 by 4, and you always have to multiply or divide by the same thing if its a ratio.

Which inequality is represented by the graph?
Taya2010 [7]

Answer:

Option B

Step-by-step explanation:

Notice that the region of the inequality is bounded by a line.

The first thing to do is find the equation of this line.

Note that the line intersects the x-axis at x = 3.5 and intercepts the y-axis at y = -2.5

We know that the equation of a line has the following form:

y = mx + b

Where m is the slope of the line and b is the intercept with the y axis.

So we already know that:

b = -2.5 = -\frac{5}{2}

Then we know that when x = 3.5 then y = 0

Thus:

0 = 3.5m -2.5

Ahroa we clear m.

m = \frac{2.5}{3.5}\\\\m = \frac{5}{7}

Then, the equation of the line is:

y = \frac{5}{7}x -\frac{5}{2}

We can also multiply by -2 both sides of the equation and we have:

-2y = -\frac{10}{7}x +5

Then:

\frac{10}{7}x -2y =5

The option that contains this equation is option B.

To verify it, enter a point within the shaded region, such as the point (0,0), in the selected inequality. If the inequality is satisfied then option B is correct

\frac{10}{7}x -2y\leq5\\\\\frac{10}{7}(0) -2(0)\leq5\\\\0\leq5

The inequality is satisfied because 0 is less than 5. Then the correct option is B
