India has a population density of 840 people per sq. mile. If we estimate the population of the US to be 300,000,000 and the total land area to be 3,500,000 sq miles, what is our population density?
85.7 people/ sq mi
8 people/ sq mi
840 people/sq mi
300,000,000 people/ sq mi

Answers

Answer:

A. 85.7 people/ sq mi

In 2009, a town's population was about 9,000 residents. In 2014, the population was about 12,500 residents. Which linear model represents the town's population, p, as a function of t, the time in years after 2007

Answers

Answer:

Population function (Based on 2007) =  7,600 + 700n

Step-by-step explanation:

Given:

Population in 2009 = 9,000

Population in 2014 = 12,500

Computation:

Increase in population per year = [12,500 - 9,000] / 5

Increase in population per year = 700

Population in 2007 = 9,000 - [2 x 700]

Population in 2007 = 7,600

Population function (Based on 2007) =  7,600 + 700n

n = number of year

E 2\5 × 3/4

Answer:

B, C and E

Step-by-step explanation:

The area of the shaded section above is [tex]\frac{24}{80}[/tex], which means 24 boxes out of 80 are shaded. It can be reduced to its lowest term:

[tex]\frac{24}{80}[/tex] ÷ [tex]\frac{8}{8}[/tex] = [tex]\frac{3}{10}[/tex]

Now, that we know the lowest term, we have to look for similar fractions based on the product for each choice.

A. [tex]\frac{5}{8}[/tex] x[tex]\frac{5}{10}[/tex] = [tex]\frac{25}{80}[/tex] or [tex]\frac{5}{16}[/tex]

Therefore choice A is not a correct expression.

B. [tex]\frac{4}{10}[/tex] x [tex]\frac{6}{8}[/tex] = [tex]\frac{24}{80}[/tex] or [tex]\frac{3}{10}[/tex]

Therefore, choice B is a correct expression.

C. [tex]\frac{3}{5}[/tex] x [tex]\frac{1}{2}[/tex] = [tex]\frac{3}{10}[/tex]

Therefore, choice C is a correct expression.

D. [tex]\frac{4}{8}[/tex] x [tex]\frac{4}{6}[/tex] = [tex]\frac{16}{64}[/tex] or [tex]\frac{1}{4}[/tex]

Therefore, choice D is not a correct expression.

E. [tex]\frac{2}{5}[/tex] x [tex]\frac{3}{4}[/tex] = [tex]\frac{6}{20}[/tex] or [tex]\frac{3}{10}[/tex]

Therefore choice E is a correct expression.

HELP ASAP YALL- PLS

Answers

Answer: x = 4

Step-by-step explanation:

since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.

so, i redrew them next to each other, so i could compare them easily.

i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!

so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.

hope this helps! xoxo
