<u><em>Answer:</em></u>
1- The constant of variation is 
2- The constant of variation is 
<u><em>Explanation:</em></u>
When two variables are in direct variation, this means that when one of them increases, the other increases and vice versa
<u>A direct variation relation is represented as follows:</u>
y = kx
where k is the constant of variation
Now, to get the constant of variation, all we have to do is substitute with the given x and y variables and solve for k
<u>For the given problems:</u>
<u>1- 
</u>
<u>Therefore:</u>
<u>2- 
</u>
<u>Therefore:</u>
Hope this helps :)
Answer: If the 40% off coupon is used, the subtotal will be $12.69
The gratuity would be exactly $4.23 (He will probably leave $4.25)
Step-by-step explanation: To find out the amount of the discount
.40 × 21.15 = 8.46
To find the new subtotal, subtract 12.15 - 8.46 = 12.69
To figure the tip: .20 × 21.15 = 4.23
Changing the percent to a decimal means divide the 20 by 100.
Imagine a chemist is in the lab and trying to make some chemical reactions happen. In one reaction she reacts chemicals in an exothermic reaction and there is an increase in entropy. A second chemical reaction she is trying to run is endothermic and there is a decrease in entropy. Which of the two reactions is more likely to occur and why?
Answer:
indeed
Step-by-step explanation:
just carry the one when adding
