Answer:
So the coordinates of M are (8.5,2.17)
Step-by-step explanation:
To obtain a 3:5 ratio, the x coordinate of M is 3/5 of the way between the x-coordinate of X (1) and the x-coordinate of Y (10).
3/5 of that distance = 3/5 * (10 - 1) = 7.5, which you add to the x-coordinate of X(1), to get the x-coordinate of M (8.5).
Similarly, the y-coordinate of M is 3/5 of the way between the y-coordinate of X (-2) and the y-coordinate of y (3). 5/6 of that distance = 3/5* (3 - - 2) = 4.17, which you add to the y-coordinate of X(-2), to get the y-coordinate of M(2.17).
So the coordinates of M are (8.5,2.17)
Answer:
x = ![\frac{9}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B80%7D)
Step-by-step explanation:
Given
x +
= ![\frac{9}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B16%7D)
Multiply through by 80 ( the LCM of 20 and 16 ) to clear the fractions
80x + 36 = 45 ( subtract 36 from both sides )
80x = 9 ( divide both sides by 80 )
x = ![\frac{9}{80}](https://tex.z-dn.net/?f=%5Cfrac%7B9%7D%7B80%7D)
Answer:
10
Step-by-step explanation:
We can use the Pythagorean theorem since this is a right triangle
a^2 + b^2 = c^2
8^2 + 6^2 = c^2
64+36 = c^2
100 = c^2
Take the square root of each side
sqrt(100) = sqrt(c^2)
10 = c
