So since 2/5 of the washing machines have been sold that means 3/5 remain in the store 
 
first find the number of washing machines that were in the store before any were sold 

X is the number of washing machines in the store before selling

18=(3/5)X

18/(3/5)=X
X=18*(5/3)
X=30

so at the beginning there were 30 machines

then multiply the percent sold (2/5) by the number at beginning to find the number sold

(2/5)*30=12

so 12 machines were sold

to find the cost per machine divide the total price by number of machines sold so 

$3840/12= $320 

so the answer is $320 per machine

Answer:

c = 150m+3000

Step-by-step explanation:

So if 150 is the monthly payment and c is the total cost you'd be looking for c and 150 would be multiplied by m for how ever many months is takes to pay it off. You would then just add on the 3000 dollar deposit since its just a one time payment to start out with.

yulyashka [42]

Answer:

172.5

Step-by-step explanation:

Use similar triangles and a proportion.

(tree height)/(tree shadow length) = (your height)/(your shadow length)

x/(270 ft)= (5 ft 9 in.)/(9 ft)

x/(270 ft)= (5 ft + 9/12 ft)/(9 ft)

x/(270 ft)= (5.75 ft)/(9 ft)

9x = 270 * 5.75 ft

x = 30 * 5.75 ft

x = 172.5 ft

C= pi/3 = 180/3 = 60 degrees

cosine 60 deg = 0.5

c²=2²+3²-[2×2×3×0.5]

c²=7

c=√7

c=2.645 ;length of third side of angle
