The grizzly bear population in yellowstone national park in 1970 was about 270.Over the next 35 years,it increased by about 115%
yawa3891 [41]

Answer:

581

Step-by-step explanation:

<u>Population of Grizzlys</u>

1970   >>>   270

2005   >>>   115% INCREASE

We need to find 115% of 270 and increase 270 by that amount. Firstly, converting percentage to decimal (division by 100):

115/100 = 1.15

So, that would be now:

1.15 * 270 = 310.5

Increasing, we get:

270 + 310.5 = 580.5

We round to 581

In 2005, the population was about 581

VladimirAG [237]
1/2 was broccoli and 1/2 was mushroom...

he ate 2/3 of the broccoli part......2/3 of 1/2 = 2/3 * 1/2 = 2/6 = 1/3
he ate 1/4 of the mushroom part....1/4 of 1/2 = 1/4 * 1/2 = 1/8

so he ate 1/3 + 1/8 = 8/24 + 3/24 = 11/24 <==
