A=xy
If there is 10% increase in x then,
New value of x = x + 10%of x =1.1x
similarly for y
New value of y after increase= 1.1 y
New value of A after increase in x and y = 1 .1x × 1.1 y= 1.21xy
now
increase amount in A= New value of A - old value of A
=1.21xy - xy= 0.21xy
percentage increase in A= (0.21xy÷xy )× 100= 21%
Answer:
10 hours
Step-by-step explanation:
Find the unit rate by dividing kilograms/hours. 16 kilograms in 8 hours is 16/8=2 kg per hour. If 20 kilograms, then divide 20 by the unit rate 2.
20kg/2kg per hour = 10 hours
Answer:
The Ganges
Step-by-step explanation:
Answer: ∠MON = 15°
Step-by-step explanation:
∠LON = ∠LOM + ∠MON
(9x + 44) + (6x+3) = 77
9x + 6x + 44 + 3 = 77
15x + 47 = 77
15x = 30
x = 2
∠MON = 6(2) + 3 = 15
Given that the distribution of colors for plain MM andies is as follows:
<span>Colors - Purple Yellow Red Orange Green Blue Brown
Percentage - 20% 20% 20% 10% 10% 10% 10%
Suppose one candy is taken at random from a large bag of plain MM candies, the probability that the candy is purple of orange is given by:
P(purple candy or orange candy) = P(purple candy) + P(orange candy) = 20% + 10% = 30%
