Answer: All three of the altitudes lie entirely outside the triangle.

Step-by-step explanation:

The orthocenter is the center of the triangle formed by creating all the altitudes of each side.  

The altitude of a triangle is formed by creating a line from each vertex that is perpendicular to the opposite side.  

In acute traingle , the orthocenter lies inside it.

In right angled triangle, the orthocenter lies on the triangle.

In obtuse triangle , the orthocenter lies outside the triangle because all the three altitudes meet outside .

So, the best explains why the orthocenter of an obtuse triangle is outside the triangle : All three of the altitudes lie entirely outside the triangle.

Can somebody PLEASE help !!!

Answer:

Elissa needs 4 quarts of paint, or 1 gallon.

Step-by-step explanation:

Elissa's room is in the shape of a rectangular prism.  Assuming that she will only be painting the walls and not the floor or ceiling, you just need to calculate the area of the four walls - front and back and side to side.  Based on the dimensions given, the area of Elissa's front and back walls are 8 ft x 9 ft or 72 ft² for each wall.  Since there are two, we take that area times two: 72 x 2 = 144 ft².

Elissa's side walls are 8 ft x 13 ft or 104 ft² for each wall.  Since there are two, we take this area times two:  104 x 2 = 208 ft².

To find the total area needed to paint, we add all four walls:  144 + 208 = 352 ft².  Since a quart of paint covers 100 ft² and a gallon covers 400 ft², Elissa can either purchase 4 quarts of paint or 1 gallon to paint her bedroom.

solong [7]
The ratio of the areas is 340/1158 = 170/579thus the ratio of the side lengths is sqrt(170)/sqrt(579)  = .5418the ratio of volumes is the side length ratio cubed = .5418^3 = .159Volume of smaller solid  = (.159)(1712) = 272.37

Subtract −7n+2 ​​from 2n−1 ​. What is the answer? A.−5n+1 B.9n−3 C.9n + 1 D.−9n+3
Ludmilka [50]
Make sure that the subtraction is set up in the correct order. We are subtracting -7+2 FROM 2n-1.

(2n-1) - (-7n+2)

Distribute the negative.

(2n-1) + (7n-2)

Combine like terms.

9n - 3

The answer is B.
