the cost price of machine is 2,50,000.if the rate of depreciation is 10% per year find the depreciation in price of machine after two years.​

Answers

Answer 1
Answer:

Step-by-step explanation:

cost price= 250000

depreciation= 10%

time or years= 2

depreciation price = cost price× depreciation%

2,50,000×10%

2,50,000×10/100

25,000

then 2 years depreciation = 1 year depreciation price ×number of years

25,000× 2

50,000

therefore depreciation price of machine after 2 years is 50,000

Can someone help me?

Answers

in the figure you can say ∠1 + ∠4 = 180° because both together make a line so you can say : 63° + ∠4 = 180° ⇒ ∠4 = 180° - 63 ° = 117 ° so the answer is :
∠4 = 117° :)))
i hope this is helpful 
have a nice day 
since j is a straight line, angle 1+angle 4=180
angle1=63
find angle 4
angle1+angle4=180
63+angle4=180
subtract 63 from both sidess
angle4=117
the answer is 117 degrees

Mrs.Jacobsen wants to order toy instruments. whistles: 25 items is $21.25, 50 items $36.00,and 80 items $60.00. what is the difference between the highest unit price for whistles and the lowest unit price for whistles?

Answers

Answer: Our required answer is $0.13.

Step-by-step explanation:

Since we have given that

25 items purchased @ $21.25

So its unit price is given by

(21.25)/(25)=0.85

50 items purchased @ 36.00

So, its unit price is given by

(36)/(50)=0.72

80 items purchased @ 60.00

So, its unit price is given by

(60)/(80)=0.75

So, Highest unit price for the whistles will be $0.85

Lowest unit price for the whistles will be $ 0.72

Difference between the highest unit price and lowest unit price for whistles will be

0.85-0.72=\$0.13

Hence, our required answer is $0.13.

Two-ninths of the total number of batteries in Richard's desk drawer is madeup of 16 batteries. How many batteries are there in the drawer?

You are told 2/9 = 16

Let total number of batteries = x

So you now have 2/9x = 16

To find x divide both sides by 2/9

X = 72 total batteries

Jamie has a board that is 8 feet long. He cuts the board into three equal pieces. How long is each piece

Answers

so picture a 8feet long board, and you basically cut it into 3 equal pieces as it says. so you should set it up as 8/3 which is 2.6666666. so you can round that up by 2.67 per each equal pieces.
Divide 8 into 3 pieces (this can be set out as 8/3) and you get 2.6666... Or you can round it up to 2.7.
