Find the distance between the two points rounding to the nearest tenth (if necessary).
mote1985 [20]

<u>Understanding:</u>

This can be easily solved by using the distance formula which is

d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2} }\\

d: distance

(x_{1},y_{1}): coordinates of the first point, in our case it is (1,-5)

(x_{2},y_{2}): coordinates of the second point, (4,-1)

<u>Solution:</u>

<u></u>d=\sqrt{[(4)-(1)]^{2}+[(-1)-(-5)]^2}\\=\sqrt{(3)^2+(4)^2}\\=  \sqrt{9+16} \\=\sqrt{25}\\= 5<u></u>

The distance between the two points is 5.

In math class the girl to boy ratio is 8 to 6 if there are 24 girls in the class , how many boys are there ?
Volgvan

Answer:  The required number of boys in the class is 18.

Step-by-step explanation: Given that in math class, the girl to boy ratio is 8 to 6 and there are 24 girls in the class.

We are to find the number of boys in the class.

Let 8x and 6x represents the number of girls and boys in the class.

Then, according to the given information, we have

8x=24\\\\\Rightarrow x=\dfrac{24}{8}\\\\\Rightarrow x=3.

Therefore, the number of boys in the class is given by

6x=6\times3=18.

Thus, the required number of boys in the class is 18.
