Answer:
c = (y-0.13y)(1.08)
Step-by-step explanation:
c = cost and y = the original price
The amount of money off is 13% of y, or 0.13 of y. You would subtract that from y to get the price of the cards with the discount. For final cost, you need the cost of the cards (1) plus the cost of tax (8%, or 0.08). 1+0.08 is 1.08, so that's what you would multiply y by to get the final cost of the cards.

Hello! So remember that the dependent always depends on something now put your smart cap on and you got this! I believe in you!
Use the sin(a - b) formula.
<span>sin(90 - x) = </span>
<span>sin90 cosx - cos90 sinx = </span>
<span>1 cosx - 0 sinx = </span>
cosx
Answer:
Example 1:
Given that y varies proportionally with x , with a constant of proportionality k=1/3 , find y when x=12 .
Write the equation of the proportional relationship.
The variable x varies proportionally with y with a constant of proportionality equal to 1/3
So, y=1/3x
Substitute the given x value.
y=1/3×12
y=4

Answer: 9.7</h3>
======================================================
Explanation:
See the diagram below.
The diagram shows we have a right triangle with these side lengths:
- a = 8 meters
- b = 5.5 meters
- c = unknown hypotenuse
We'll use the pythagorean theorem to find c
