Answer:
a) What is the amount off the original price?
= $8.4
b) What is the new price for the pair of shoes?
= $33.6
Step-by-step explanation:
a) What is the amount off the original price?
We are told that:
The sale price is 20% off the original price.
Original price = $42
Hence:
$42 × 20%
$42 × 20/100
= $8.4
b) What is the new price for the pair of shoes?
The new price =
0riginal price - Amount off the original price
= $42 - $8.4
= $33.6
The original price = $33.6
Use trigonometry.
tan30° = perpendicular / base
Here for angle 30° , x is perpendicular while 10 is the base.
tan30° = 1/√3
1/√3 = x/10
x = 10/✓3
By rationalising
x = 10√3/3

Answer:
B) 5 x 4 x 3 x 2 x 1
Step-by-step explanation:
When you see a ! directly next to a number (such as 5!), it means that you are multiplying starting from that number, and stepping down each time:
5! = 5 * 4 * 3 * 2 * 1
For example, take factoral 10: 10!
10! = 10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1 = 3,628,800
In this case, you are multiplying 5!.
5! = 5 * 4 * 3 * 2 * 1 = (20) * (6) * 1 = 120
5! = 120
