Answer:

Step-by-step explanation:

A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.

The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.

Perimeter= 10x +15

Length of each side

= (10x +15) ÷5

= 2x +3

Sheila is a wildlife biologist. Her daily task is to count the number of wild turkeys and white-tail deer in a large game reserv

Lilit [14]

Given:
wild turkey ; 12 in the first hour and cumulative number increases by 40% per hour
white-tail deer ; 18 in the first hour and 10 deer each hour after that.

wild turkery: 12 * (1.40)^n-1 ; n is the number of hour
white-tail deer: 18 + 10^n-1 ; n is the number of hour

n wild turkey white-tail deer
1 12 18
2 17 28
3 24 38
4 33 48
5 46 58
6 65 68
7 90 78

It would be hour 7 after sunrise that the cumulative count of the turkeys first exceed the cumulative count of the deer.

The population of California is approximately 38,040,000. The population of Texas is approximately 26.06 x 10^6 . The population

Salsk061 [2.6K]

Answer:

this is it

Step-by-step explanation:

The population of California is approximately 38,040,000. The population of Texas is approximately 26.06 x 106 . The population of New York State is approximately 1.96 x 107

38,040,000 = 3.804 x 107

26.06 x 106 = 2.606 x 107

Which state has the highest approximate population? Show work and/or Explain.

NY: 1.96 x 107 = 19,600,000

TX: 2.606 x 107 = 26,060,000

CA: 3.804 x 107 = 38,040,000

California has the highest approximate population.

Find the sum of the approximate population of California and New York State.

(3.804 x 107) + (1.96 x 107) = (3.804 +1.96) x 107 = 5.764 x 107

Find the difference in the approximate population of Texas and New York State.

(2.606 x 107) - (1.96 x 107) = 0.646 x 107 = 6.46 x 106

Δ HFM- Δ PST What is the perimeter of triangle PST? Enter your answer in the box.

fgiga [73]

Step-by-step explanation:

$\triangle HFM \sim \triangle PST... (Given) \\\\\therefore \frac{HF}{PS} = \frac{FM}{ST} = \frac{HM}{PT}...(csst) \\ \\ \therefore \frac{30}{PS} = \frac{35}{ST} = \frac{45}{9}\\ \\ \therefore \frac{30}{PS} = \frac{35}{ST} = \frac{5}{1} \\ \\ \therefore \frac{30}{PS} = \frac{5}{1} \\ \\ \therefore PS = \frac{30}{5} \\ \\\boxed{ \therefore PS = 6 }\\ \\ \because \: \frac{35}{ST} = \frac{5}{1} \\ \\ \therefore \: ST = \frac{35}{5} \\ \\ \boxed{\therefore \: ST = 7} \\ \\ perimeter \: of \: \triangle PST \\ = 9 + 7 + 6 \\ = 22 \: units$
