The distance between the two points rounding to the nearest tenth<br> (-8,-6) and (-3,-4)

Lesechka [4]

Answer:

5.4

Step-by-step explanation:

To find the distance between two points, $(x_1,y_1)$ and $(x_2,y_2)$ , plug them into the following equation:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}$

Two negatives make a positive

$d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4$

Therefore, the distance between the two points rounded to the nearest tenth is 5.4.

I hope this helps!

wlad13 [49]

Answer: The quantity of the water received by each student = 3.75 liters.

Step-by-step explanation:

Given: Total water = 18.75 liters

Total students =5

If each student in the group used the same amount of water for their experiment, then the quantity of the water received by each student = $\dfrac{\text{Total quantity}}{\text{Total students}}$

$=\dfrac{18.75}{5}\\\\=3.75\ liters$

The quantity of the water received by each student = 3.75 liters.
