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 = \frac{578}{2790}*100 = 20.71

                                   = 20.7%

It takes omar four minutes to eat eight carrots sticks. how long does it take him to eat one ?
astra-53 [7]
It takes Omar 30 seconds to eat one considering he ate 8 in 4 minutes ...

If we really wanted to we could turn this into the fraction 8/4
8 being the amount of carrot sticks he ate and 4 being the time it took
now all u have to do is simplify that turns into 2/1 and since the 1 is one minute and her can eat 2 in one minute we can safely say he eats 1 carrot stick every 30 seconds 

:) hope this helps!!

NISA [10]
There are 72 green pens.

There is 9 times as many white pens from 2 to 18, so there has to be 9 times as many green pens because of the ratio. 9 times 8 is 72.
