A 10-foot ladder leans against a wall. It hits the wall 9 feet up. How far is the base of the ladder from the wall? Apply the Pythagorean Theorem to this problem
triangle
side S1 = 9 feet
hypotenuse H = 10 feet
side S2 - X = ?
the Pythagorean Theorem
H x H = S1 x S1 + S2 x S2 = S1 x S1 + X x X
X x X = H x H - S1 x S1 = 10 x 10 - 9 x 9 = 100 - 91 = 9
X x X = 9
X = 3
How far is the base of the ladder from the wall? 3 feet
check:
H x H = S1 x S1 + X x X
10 x 10 = 9 x 9 + 3 x 3
100 = 91 +9 = 100
Answer: sour
Step-by-step explanation:
Answer:
<h2>
c. 3x + 8y = -1
</h2><h2>
-12x - 32y = 4</h2>
Step-by-step explanation:
If we divide second equatoin by (-4) we get the first equation.
Two identical equations means infinite number of solutions.
The constant of proportionality is for every 1 x, there is 0.25 y. y = 0.25, and on a graph, x is always the "1." Since x is worth 1, y must be worth 0.25.
Answer:She can buy 5 goldfish.
Step-by-step explanation: If you divide the amount of money she has to spend by the cost of the goldfish;
$11/5 = 5.5
Since she can’t buy 5 and a half goldfish, she can only buy 5.
