Mathematics

Answer:

x = 29 1/3 degrees

Step-by-step explanation:

A triangle has 3 angle that total 180 degrees.

The three angles given are 82 degrees ,2x+10 degrees and x degrees.

So,  

82+ (2x+10) + x = 180

Combine like terms.

92 + 3x = 180

Subtract 92 from each side

3x = 180 -92

3x = 88

divide each side by 3

3x/3 = 88/3

Change 88/ 3 to a mixed number

3 goes in to 88 29 times  with 1 left over.

x = 29 1/3 degrees

Population in 1990 was 134 million. In 2000 it was 139 million. What was it in 2014
mihalych1998 [28]
Well first lets find the ROC (rate of change) in the sets of data.
1990 -> 134
2000 -> 139

so lets find the difference from the years given
2000-1990=10  so there is a 10 year gab
139-134=5  so there is a 5 million increase in the population 

so divide 10 by 5 which gives us 2, so every year there is a 2 million increase in the population. so from 2000 to 2014 there is 14 years, so 
14 x 2= 28, then add that to the latest population data
139+28=167
so the population in 2014 would be 167 million 

Hope this helped!!

7) The weight of a box is 125kg. Le Goff charge €1.92 per kg to deliver these boxes to
Sonbull [250]

Answer:

€ 240

Step-by-step explanation:

<h2><u>How much does Le Goff charge to deliver each box?</u></h2><h3><u>ratio</u></h3>

since 1 kg is € 1.92

we can find out the cost of 125 kg by using<em><u> cross multiplication</u></em>

kg                      €

1              :        1.92

125         :          x

x = 1.92 * 125

x = 240

<u>Le Goff charges € 240 to deliver each box</u>

Jack is car salesman who works strictly on commision. For every car he sells, he earns 2% commision. Cars sell for $35,000 each.
Dafna11 [192]
He earns 2% commission for every car...and each car sells for 35,000....
so for every car, he earns (0.02(35000) = $ 700

700c = 5000
c = 5000/700
c = 7.14....so he would basically have to sell 8 cars because 7 cars wouldnt quite be enough
