Answer:
h = 19.6 ft
Step-by-step explanation:
Given that,
A 20 ft ladder 4ft from the base of the wall.
The height of the ladder, H = 20 ft
The base distance, b = 4 ft
We need to find the height of the reach. Let it is P.
Using Pythagoras theorem,
or
P = 19.6 ft
So, the height is 19.6 ft.
The area of a kite is (1/2) * x * y, where x and y are the length of the two diagonals. In this case, the length of the two diagonals are 10 ft and 2 ft.
<span>Plug that in the equation, we get 1/2 * 2 * 10. We multiply the 2 and 10 first to get 20, that leaves us with 1/2 x 20, which is 10, so the area of this kite is 10 ft squared.</span>
The value of a should be 2000. Hope this helps.
Answer:
<h2>12 computers = 24 students</h2>
Step-by-step explanation:
<h2>3 computers = 6 students</h2><h2>X computers = 24 students</h2><h2>cross multiply</h2><h2>6x = 3 × 24</h2><h2>6x = 72</h2><h2>divide both sides by 6</h2><h2>X = 12</h2>
139 is suppose to be 140 and 18 is suppose to be 20, 140 x 20 = 2800
Home this works
