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

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]

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.
