Answer:
39,270 ways.
Step-by-step explanation:
That is the number of permutations of 3 from 35.
35P3 = 35! / (35-3)!
= 35*34*33
= 39270.
Answer:
a) $8.80
b) 40%
Step-by-step explanation:
<u>Part (a)</u>
Given:
- Original price = $22
- Discounted price = $13.20
Original price - discounted price
= $22 - $13.20
= $8.80
<u>Part (b)</u>
percentage = (amount discounted ÷ original price) x 100
= (8.80 ÷ 22) x 100
= 40%
Answer:
Step-by-step explanation:
The opposing side and the hypotenuse for the angle are given.
Remember, when the opposing side and the hypotenuse are given, take the cos ratio.
- cosx = 7/9
- x = cos⁻¹ (7/9)
- x = 38.9424413°
- <u>x = 39°</u>
just substitute 10 into the equation
10=2x-6
add 6 to both sides
16=2x
divide both sides by 2
x=8
