a motor boat covers a certain distance downstream in a river in 9 hours it covers the same distance upstream in 10 hours the speed of the stream is one kilometre per hour find the speed of boat in still water

Answer»

Answer:

HENCE speed of BOAT in STILL water=19 km/hr

Step-by-step explanation:

Let speed of boat =x km/hr

speed of stream=1 km/hr

speed in downstream=x+1

distance covered in 9 HRS

=(x+1)*9

speed in upstream=x-1

distance in 10 hrs

=10*(x-1)

Both these DISTANCES are same

So 10*(x-1)=9(x+1)

10x-10=9x+9

10x-9x=9+10

x=19 km/hr

hence speed of boat in still water=19 km/hr

How write community property of addition and multiplication for 6th class in detail​

Answer»

(I guess its COMMUTATIVE PROPERTY.)

Commutative property says that-

(for addition)

a+b = b +a

For example:

lets take a as 1 and b as 2.

Therefore,

a+b = 1+2 = 3

b+a = 2+1 = 3

So, commutative property is applicable for addition.

(for multiplication)-

a × b = b × a

For example :

a = 2

b = 3

a×b = 2×3 = 6

b×a = 3×2 = 6

So, commutative property is applicable for multiplication as WELL.

If R is an integer betwwn 1&9 , P-R= 2370 what is the value of R , if p is divisble by 4 &9​

Answer»

Answer:

r=6

Step-by-step explanation:

p-6=2370

p=2370+6

p=2376

sum of digits in p =2+3+7+6

=18

18 is DIVISIBLE by 9

THEREFORE p is divisible

last TWO digits of p is divisible by 4

i.e 76 is divisible by 4

therefore p is divisible by 4 and 9

(11)-4 × (11)-(2x+10)=1​

Answer»

ANSWER:

\left(11\right)-4\left(11\right)-\left(2x+10\right)=1\quad :\quad x=-22

Step-by-step EXPLANATION:

\left(11\right)-4\left(11\right)-\left(2x+10\right)=1

\gray{\mathrm{Remove\:parentheses}:\quad \left(a\right)=a}

11-4\times \:11-\left(2x+10\right)=1

\gray{\mathrm{Multiply\:the\:numbers:}\:4\times \:11=44}

11-44-\left(2x+10\right)=1

\gray{\mathrm{Subtract\:}11-44\mathrm{\:from\:both\:sides}}

11-44-\left(2x+10\right)-\left(11-44\right)=1-\left(11-44\right)

\gray{\mathrm{Simplify}}

-\left(2x+10\right)=34

\gray{\mathrm{Divide\:both\:sides\:by\:}-1}

\dfrac{-\left(2x+10\right)}{-1}=\dfrac{34}{-1}

\gray{\mathrm{Simplify}}

2x+10=-34

\gray{\mathrm{Subtract\:}10\mathrm{\:from\:both\:sides}}

2x+10-10=-34-10

\gray{\mathrm{Simplify}}

2x=-44
