Ket [755]3 years ago

Answer:

3\sqrt{5}

Step-by-step explanation:

View the distance as a hypotenuse of a triangle ΔABC (∠C = 90°).

Use Pythagorean theorem:

AB = y1 - y2 = 9 - 6 = 3

AC = x1 - x2 = 4 - (-2) = 6

Now calculate BC which is also the distance needed:

BC^{2} =AC^{2} +AB^{2}

BC^{2} = 6^{2} + 3^{2} = 45

BC = \sqrt{45} = \sqrt{3 * 3 * 5} (BC > 0)

BC = 3\sqrt{5}

Make me the brainliest ;)

HELP PLEASE <br><br> this is geometry and i don't understand anything on this test
sveta [45]

Answer:

It could be 8 or 5. I think it's 5

Step-by-step explanation:

This is a pretty weird problem. I see the DC is 10 so then one would think that it is 5. EF however is 7. I think the most logical answer would be 5. Using process of elimination, we can narrow it down to 5 and 8 but I feel that 5 makes more sense. the other 2 sides are obviously longer so 5 is most likely correct.

the population of a town is 1,03.500 if 56%of the population is male find the number of females in the town
bija089 [108]
The population you gave isn't formatted correctly so I'll solve the problem assuming you mean 103,500.

First we find the number of males from the percentage given:

0.56 * 103500 = 57960 males

Subtract the number of males from the total population to get the number of females:

103500 - 57960 = 45540 females

You could solve the problem by finding the percentage of females first. Since there are 56% males, that means there are 100-56 = 44% females.

0.44 * 103500 = 45540

The answer is 45540.
