Using the Pythagorean theorem:
90^2 +90^2 = X^2
8100 + 8100 = x^2
16,200 = x^2
X = √16,200
X = 127.28 feet.
Rounded to the nearest foot = 127 feet.
The total percent discount on the jeans is 35% amounting to $77
<h3>Discount</h3>
- Cost of a pair of jean = $220
- Discount from last season = 15%
- Discount from Thanksgiving day = 20%
Total percentage discount = 15% + 20%
= 35%
Amount of discount = Total percentage discount × Cost of a pair of jean
= 35% × $220
= 0.35 × 220
= $77
Therefore, the total percent discount on the jeans is 35% amounting to $77

Read it carefully. It's telling you the answer in the problem! There is one teacher for every 11 students. Of course there are more students!
Step-by-step explanation:
cost of 1 kg of jam = x
cost of 1 kg of butter = y
3x + 2y = 29 .....1
6x + 3y = 54 .....2
.....1 × 2 both sides of equation
6x + 4y = 58 .....3
.....3 - ......2
y = 4
replace y = 4 in 1......
3x + 8 = 29
x = 7
