Let's say the length of the ladder is "d". Since the distance from the bottom of the ladder to the building is 16 feet less than the length, we can write this as d - 16.
The distance from the ground to the top of the ladder is 2 feet less than the length of the ladder, so we can denote this as
d - 2.
The shape made by the ground, ladder, and side of the building is a right triangle, and we just found its legs. We can use the Pythagorean Theorem to solve for "d" and find how far up the side of the building the ladder is:
(d - 16)^2 + (d - 2)^2 = d^2
(d^2 - 32d + 256) + (d^2 - 4d + 4) = d^2
2d^2 - 36d + 260 = d^2
d^2 - 36d + 260 = 0
(d - 26) * (d - 10) = 0
d = 26 or d = 10
The answer d = 10 does not fit in this case because it isn't possible to have 16 feet less of 10 feet; it would be negative!
So, d = 26. The top of the ladder to the ground is 2 less than d, so we do 26 - 2 = 24 feet.
The answer is 24 feet.
Answer:
15/100*1800=15*1800/100=15*18=270
Step-by-step explanation:
1800-270=1530 therefore answer is 1530

Y-intercept form because it is more commonly used and easier to remember. The foundation of the y-intercept is easier to put in a graphing calculator also as it is already set to y=
Answer:
So we will be saving a total of $0.7 at new rate
Step-by-step explanation:
Given:
Original price =$ 0.69
New price = $ 2.75 per 5 switches
To find:
Saving = ?
Solution:
The original per price of the switch is given as = $ 0.69
Discounted price of 5 switches at $2.75
5 Switch price at original price = Original price * No of switches
= 0.69 * 5
= $ 3.45
Total saving at buying 5 switches = 3.45 - 2.75
=$0.7
So we will be saving a total of $0.7 at new rate
