Answer:
x is greater than or equal to 31.
Step-by-step explanation:
Let's pretend the greater than symbol is greater than or equal to lol
-5x+5>160-10x
5x+5>160
5x>155
x>31
I can go more in depth if you'd like!
Answer:
A. Right triangle
Step-by-step explanation:
For problems like this, make use of the Pythagorean Theorem to determine which triangle can be formed.
Thus, there are always 3 sides in a ∆, as we've been given in the question above. The following rule can be use to find out which triangle can be formed:
1. If a² + b² = c², a right triangle is formed.
2. If a² + b² > c², an acute triangle is formed.
3. If a² + b² < c², an obtuse triangle is formed.
Where, c is always the longest side, while a and b are the 2 other shorter side lengths compared to c.
From the question given,
a = 24
b = 45, while
c = 51
Let's find out which of the 3 rules this side lengths fit in, to determine the triangle they form.
24² + 45² ? 51²
576 + 2025 ? 2601
2601 = 2601 (this fits into rule 1 stated above)
Therefore, the side lengths given in the question would form a right triangle.
Answer:
11.8
Step-by-step explanation:
Rounding 59.03 you get 59.
20% of 59 = 11.8
11.8 = the tip.
Answer:
n = -5
Step-by-step explanation:
Answer:
-1/6
Step-by-step explanation:
First find the slope of the line through the points
m = (y2-y1)/(x2-x1)
= (-4-8)/(1-3)
= -12/-2
=6
Now we need to find the slope of the line that is perpendicular
Perpendicular lines multiply to -1
6 * mp = -1
mp = -1/6
