Answer:
0.75m/s
Step-by-step explanation:
<em>Speed formula: ⇒ 
</em>
<em>Divide by the numbers from left to right.</em>
<em>S=18</em>
<em>T=24</em>
<em>18/24=0.75</em>
<em>0.75m/s is the correct answer.</em>
<em>I hope this helps you, and have a wonderful day!</em>
Answer:10
Step-by-step explanation:26/13 is 2 therefore 5 times 2 is 10
Answer:
1/14
Step-by-step explanation:
Let L represent the ladder length, and x the distance the horiz. ladder reaches out from the wall. Then L = x + 3, where x is the distance of the bottom of the ladder from the wall when the top of the ladder is 9 ft. above the ground.
Consider the triangle formed by the hypotenuse (L, same as ladder length), the (vertical) side opposite the angle formed by the hypo. (with length 9 ft) and the horiz side (which we will call x). Then, according to the Pythagorean Theorem,
L^2 = x^2 + 9^2. But L = x + 3, and L^2 = x^2 + 6x + 9 = x^2 + 9^2. Solving this equation results in x=3. 6x + 9 = 9^2, or
6x + 9 = 81
6x = 72
x = 12
But L = x+3. So L=12+3, or L = 15 (feet).
