A,B,and C can do a work separately in 40,50,75daysrespectively.Band C work first for 10days and leave. How many more days will A alone take to complete the remaining work?​

Answer»

ong>Answer:

80/3 days

Step-by-step explanation:

B+ C 1 day work 1/50 + 1/ 75 = 1/30

for 10 days work = 1 / 30 × 10 = 1/ 3

remaining work = 1 - 1/ 3 = 2 / 3

let A take x days to complete work

so

1 day work of A = 1/ 40

1 / 40 × x = 2/3

x = 80/ 3 days.

Answer» ONG>Step-by-step EXPLANATION:

fog(x) = f(g(x)) = f(3x - 1) \\  =   {(3x - 1)}^{2 }-2(3x-1)+1 \\  = 9 {x}^{2}-6x + 1 - 6x  + 2 + 1 \\  = 9 {x}^{2} - 12x + 4 \\ similarly \\ gof(x) = g(f(x)) = \\  g( {x}^{2} - 2x + 1)  \\  = 3( {x}^{2}  - 2x + 1) + 1 \\  = 6 {x}^{2} - 6x + 2

Pa heelp po with solution na.sana

Answer»

ong>Answer:

angle A + angle S + angle T + Angle R = 360°

angle S + angle T = 180° [alternate SIDE angle]

75° + angle T = 180°

angle T = 180° - 75°

angle T = 105°

angle T + angle R = 180° [alternate side angle]

105° + angle R = 180°

angle R = 180° - 105°

angle R = 75°

The product of two consecutive natural number is 31 less than the sum of their squares. Find the number​

Answer» ONG>Answer:

Let TWO CONSECUTIVE natural numbers be xx and x+1x+1.

Sum of these numbers

=x+x+1=x+x+1

=2x+1=2x+1

Difference of their squares (from largest)

=(x+1)2−x2=(x+1)2−x2

=x2+2x+1−x2=x2+2x+1−x2

=2x+1=2x+1

∴∴ Both are equal.

So the answer is ALSO 31.

11. The ratio of the measures of a side of a triangle is 2:3:5. If the semiperimeter is 90cm then find the measure of the longest side of thetriangle.​

Answer»

ong>Answer:

2x + 3x + 5x = 90

10x = 90

x = 90/10

x= 9

then the sides are = 2x = 2*9 = 18

= 3x = 3*9 = 27

= 5x = 5*9 = 45

Now semiperimeter =

sum of sides of triangle/2

= 18+27+45/2

=45

using herons formula

=√s(s-a)(s-b) (s-c)

=√45(45-18)(45-27)(45-45)

= √45(27)(18)(0)

= 0
