I think the answer is 43.8.
To model this situation, we are going to use the standard linear function:

.
1. Since S represent the total amount of money in the savings account,

. We also know that each week she adds $40 to her account, so the slope of our linear equation will be

; therefore,

. Since she started her account with $750,

.
Lets replace those values in our linear function:

We can conclude that equation that models this situation is:
2. Now to find the total amount after 16 weeks, we just need to replace

with 16 in our equation and simplify:


We can conclude that the amount of money in her account after 16 weeks is $1390
Answer:
45 degrees
Step-by-step explanation:
Since all three angles would equal 180 degrees you would do 72 + 63 = 135. Then 180 - 135 = 45
hope this helps! plz mark brainliest? :)
45 percent because you and the 18 percent country and then the 27 percent rock together
