bi(two)...sector(section).  Bisector cuts the segment into two equal sections.  

BC = CD             <em>definition of perpendicular bisector</em>

BC + CD = BD    <em>segment addition postulate</em>

CD + CD = BD   <em>substitution</em>

2CD = BD          <em>added like terms</em>

2CD = 16           <em>substitution</em>

  CD = 8            <em>division property of equality</em>

CD = y + 3         <em>given per graph</em>

y  + 3 = 8           <em>transitive property</em>

  y = 5               <em>subtraction property</em>

Answer: 5

Erica earned a total of $15,450 last year from her two jobs. the amount she earned from her job at the store was $1250 more than
dimaraw [331]

If Erica earned a total of $15450 last year from both the jobs then he earns $2840 from college if she earned 1250 more than four times the amount from college from store.

Given Total amount earned=$15450,Amount earned from store is 1250 more than 4 times earned from college.

Amount from store forms an equation.

let the amount earned from college is x.

According to question:

Amount earned from store=4x+1250

Amount earned from college=x

Total amount earned=4x+1250+x

5x+1250=15450

5x=15450-1250

5x=14200

x=14200/5

x=2840

Put the value of x in 4x+1250 to get amount earned from store=4(2840)+1250=$12610.

Hence the amount earned by Erica from college is $2840.

Talja [164]
54153 square miles is equivalent to 34657920 acres. 750000 divided by 34657920 is about 0.022, which is also 2.2%

98 million divided by 750000 is about 1306.67, so the population density of the trees is 1306.67 trees per acre

292 million divided by 98 million is very close to 3, so about 3 boxes were produced per tree, on average
