The correct question is
<span>A 15-foot ladder is leaning against a house. the base of the ladder is 4 feet from the house. to the nearest tenth of a foot. </span>How high up the house does the ladder reach?
see the picture attached to better understand the problem
applying the Pythagoras Theorem
15²=4²+h²-----> h²=15²-4²-----> h²=225-16----> h=√209
h=14.46 ft------> h=14.5 ft
the answer is14.5 ft
<span>The correct answer is option B. i.e. (1,-10) two equations are y = -x^2 - 5x - 4 and y = -x^2 + 9x - 18. Now, equating both the equations we get, -x^2 - 5x - 4 = -x^2 + 9x - 18 or 14 x= 14 or x = 1. Now, y = -1 -5 -4 = -10.</span>
$137.5 is the money does Nancy have.
<u>Step-by-step explanation:</u>
The given information are,
- Steve has a total money = 55
- Nancy has a money = 250% as much money as Steve.
We know that, from the given data the money that Steve has is 55.
This means that, Nancy has money = 250% of 55.
Let us assume,
x be the total money that Nancy have.
Therefore, x = 250% of 55.
The percentage can be represented as 1 divided by 100.
⇒ x = (250 × 1/100) × 55
⇒ x = 2.5 × 55
⇒ x = 137.5
The money does Nancy have is 137.5

It's still just easier to add first though.
