Step-by-step explanation:
G(x) = 2/3 x - 6 switch x and y around and solve for y.
y = 2/3 x - 6
x = 2/3 y - 6
x + 6 = 2/3 y
3/2 x + 9 = y
how much did they sale? you can not complete the answer without a sale amount. because you are asking that they made $1,200 plus 3% of sale, but you do not have the amount they sold so it just $1,200+3% of the sale , but no number for how much they sale, but for advice i would get the total amount they sale and divide by 100 then times it by 3 then try to fill in the void on how they went from 1,200 to 2500. You need to tell us the amount they sold and then the we can answer your question, but without you will not get your answer, so your question is incomplete.
Answer:

Step-by-step explanation:
The total surface area of a cone is given by:
Surface area = 
where r is the radius of the cone, h is the height of the cone, l is the length of the cone = 
Given that h = 136 mm, r = 60 mm /2 = 30 mm, l = 140 mm. Also the top of the cone is not included in the surface area, hence the surface area becomes:

Answer: 35 m
Step-by-step explanation:
The problem is the same as:
a man is fix (not moving) and the goods train is travelling at the speed of 54+72 = 126 (km/h)
Distance = 126 km/h* 8 s=126000 m/(3600 s) * 8 s=35 m
