Answer:
110, 9.1. The total weight of the salt solution is the weight of water plus the weight of salt. So he made 100+10=110 kg of salt solution.
Step-by-step explanation:
Answer: c) 300 copies
Step-by-step explanation:
Let x represent the number of copies that you must sell to break even.
You decide to market your own custom computer software. You must invest 3,255 for computer hardware,and spend 2.90 to buy and package each disk. This means that the total cost of producing each software would be
3255 + 2.9x
If each program sells for $13.75, it means that the total revenue from selling each software would be
13.75x
In order to break even, total cost would be equal to total revenue. Therefore,
3255 + 2.9x = 13.75x
13.75x - 2.9x = 3255
10.85x = 3255
x = 3255/10.85
x = 300 copies

Answer:
3.92*10^3mm
Step-by-step explanation:
In the diagram it gives you 7900mm. There is a figure which was given underneath written 900mm. use 7900 to subtract 900 you will get 7000. Then you can use the Pythagoras theorem to solve it, with a= height, b=5800mm and c=7000mm where, a^2+b^2=c^2.
Step-by-step explanation:
7(36-2c+4)
=252 - 14c + 28
=310 - 14c
