There is no discount stated but I'm assuming this problem is the same problem I encountered before.
Original price of the telescope is $99.99
Discount: 13%
$99.99 * 13% = 12.9987 or 13
$99.99 - 13 = $86.99 or $87
New selling price is $86.99 rounded up to the nearest unit $87.00
Answer:
I know the answer .
Step-by-step explanation:
Answer:
8
Step-by-step explanation:
use trig functions
2 sides and 1 angle given
Sides given
- hypotenuse -> x
- opposite side to 30˚ -> 4
Angle
trig function associated with hyp and opp is sin
sin(x) = opp/hyp
substitute
sin 30˚ = 4/x
solve for x
0.5 = 4/x
0.5x = 4
x = 8
I think that this is just showing how you can make different percentages by multiplying/dividing by specific numbers.
