An investor has an account with stock from two different companies. Last year, her stock in Company A was worth $4150 and her stock in Company B was worth $6820. The stock in Company A has increased 6% since last year and the stock in Company B has increased 5%. What was the total percentage increase in the investor's stock account? Round your answer to the nearest tenth (if necessary).

The required percentage would be 5.4%.

Step-by-step explanation:

Since we have given that

Worth of Company A = $4150

Worth of Company B = $6820

So, increase in Company A = 6%

increase in Company B = 5%

According to question, it becomes,

So, the total percentage increase in the investor's stock account would be

Hence, the required percentage would be 5.4%.

the answer to the expression is 83

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
