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:

Population of Grizzlys

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

PLEASE HELP FAST!!! A ladder leans against a building. The top of the ladder reaches a point on the building, which is 18 feet a

weeeeeb [17]

The measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees

<h3>Angle of elevation and depression</h3>

These method is used to determine the side and angles of a triangle

From the question given, we have the following parameters

Base of the building = 7feet (Adjacent side)

Height of the building = 18 feet (Opposite side)

Required

angle of elevation of the building

Using the SOH CAH TOA identity

tanФ = opp/adj

tanФ = 18/7

Ф = 68.73 degrees

Hence the measure of the angle of elevation from the ground to the top of the ladder is 68.73 degrees

Answer:

option a) 30 : 19

Step-by-step explanation:

$Length = 7 \frac{1}{2} = \frac{15}{2}\\\\Width = 4\frac{3}{4} = \frac{19}{4}$

Ratio of length to width:

$\frac{15}{2} : \frac{19}{4}$

$=\frac{\frac{15}{2}}{\frac{19}{4}}\\\\=\frac{15}{2 } \times \frac{4}{19}\\\\=15\times \frac{2}{19}\\\\=\frac{30}{19}\\\\30 : 19$
