There are 165 deer in a state park. The population is increasing at the rate of 12% per year. Enter a prediction for how long it
Paha777 [63]
The deer population will reach 309 in approximately 6 yrs


Year 1. 165•1.12=184.8
Year 2. 184.8•1.12=206.976
Year 3. 206.976•1.12=231.813
Year 4. 231.813•1.12=259.63
Year 5. 259.63•1.12=290.785
Year 6. 290.785•1.12=325.679

Therefore it will take 6 years for the deer’s population to reach 300

samuel needs to estimate the product of 23 * 395. explain two different methods Samuel can use to estimate.
Sonbull [250]
Samuel could round both of the individual numbers, to get s rounded answer. So, he could round 23 to 20, and 395 to 400, to get a product of 8000.
Or, he could multiply the numbers first, so 23*395 to get a product of 9085, which would then round to 9000, or depends on what place value it would want to be rounded to.

A rectangle is inscribed in a circle of radius r. If the rectangle is not a square, which of the following could be the perimete
evablogger [386]

Answer:

2r(\sqrt{3}+1)

Step-by-step explanation:

A rectangle is inscribed in a circle of radius r.

Radius of the circle is 'r'  . the diameter of circle is 2 times radius is 2r

The diameter of the circle becomes the diagonal of the rectangle.

The one part of the rectangle forms a triangle with hypotenuse 2r

Triangle is a special 30:60:90 degree angle

the ratio of the special triangle is  1: \sqrt{3} :2

Hypotenuse is '2r' , so the ratio becomes

r: \sqrt{3}r :2r

So the width of the rectangle is 'r'  and length of the rectangle is \sqrt{3}r

Perimeter = 2 times length + 2 times width

perimeter = 2\sqrt{3} r+2r=2r(\sqrt{3}+1)
