Answer:
20.7%
Step-by-step explanation:
Amount of stock increased in Company A = 20% of 1790
= 0.20 * 1790 = $ 358
Investor's stock in company A this year = 1790 + 358 = $ 2148
Amount of stock increased in Company B = 22% of 1000
= 0.22 * 1000= $ 220
Investor's stock in company B this year = 1000 + 220 = $ 1220
Total amount in investor's stock account = 2148 + 1220 = $ 3368
Increased amount = 3368 - 2790 = $ 578
Increase percentage = 
= 20.71
= 20.7%
Answer:
23,500
Step-by-step explanation:
Alright, so in PEMDAS, we first do exponents. 3^2=9, and we then have 5(9)-3(3)+2. After that, we have multiplication, where we have 5*9 =45 and 3*3=9, resulting in 45-9+2 and eventually 38
One operator is missing. I will assume it is a + and that the equation is: 4y -2/5y +4/5 = -3
Solution step by step
1) Sum -4/5 to both sides
4y - 2/5y + 4/5 - 4/5 = -3 -4/5
2) Sum alike terms
18/5 y = -19/5
3) Multiply both sides by 5
18 y = -19
4) Divide both sides by 18
y = -19/18
Total time taken by the 4 relay runners all together = 3.86 minutes
= (3 * 60) + 86 seconds
= 180 + 86 seconds
= 266 seconds
As all 4 runners of the relay time take the same time to cover their individual laps, so
Time taken by each runner = 266/4 seconds
= 66.50 seconds
So the total time taken by each runner of the relay team is 66.50 seconds. I hope this is the answer you were looking for.
