Answer:
L = 18,4 ft
Step-by-step explanation:
The building, the ground, and the ladder make up a right triangle, with legs:
The distance (a) between the bottom of the ladder and the building 12 ft
The distance (b) between the gound and the window 14 ft up
The hypothenuse is the length of the ladder (L)
According to Pythagoras theorem
L² = a² + b²
L = √ (12)² + (14)²
L = √ 144 + 196
L = √ 340
L = 18,4 ft
Answer:
A rational number.
Step-by-step explanation
A rational number is a ratio of whole numbers.
1/3 is the ratio of 1:3
3:1 becomes 3/1 = 3
32:10 can be written 32/10 or 16/5 or 3.2
16/5 is a rational number 16 and 5 are integers, 5 is not equal to 0.
Therefore, 3.2 which can be expressed as 16/5 is a rational number.
Answer: No
Step-by-step explanation: No, because in order for it to be equivalent, it has to be 60:80 = 60 to 80.
<h3>I'll teach you how to solve y^2 + 4y - 16y+3y^2</h3>
-----------------------------------------------------------------
y^2 + 4y - 16y+3y^2
Group like terms:
y^2+ 3y^2+4y-16y
Add similar elements:
4y^2+4y-16y
Add similar elements:
4y^2-12y
Your Answer Is (D) 4y^2-12y
