Working alone, Ryan can dig a 10 ft by 10 ft hole in 5 hours Castel can dig the same hole in 6 hours how long would it take them

Fed [463]

Answer:

The time taken by both boys to complete work = 2.73 hours

Step-by-step explanation:

Time taken by rayan to dig hole $T_{1}$ = 5 hours

Time taken by castel to dig hole $T_{2}$ = 6 hours

Now the time taken by both persons working together

$T = \frac{T_{1} T_{2} }{T_{1} + T_{2}}$

Put all the values in above formula we get

$T = \frac{ 30 }{6 + 5}$

$T = \frac{30}{11}$

T = 2.73 hours

Therefore the time taken by both boys to complete work = 2.73 hours

Kat is painting the edge of a triangular stage prop with reflective orange paint. The lengths of the edges of the triangle are (

Eva8 [605]

Plug 4 in for every x

(3*4)-4=8
(4^2)-1=15 [(4^2) is 4*4]
(2*(4^2))-15= 15 [because of PEMDAS the exponent comes first and then multiply by 2 then subtract]

Perimeter is the sum of the lengths so add up all the sides from above
8+15+15=38

Please help me in the question of commission ! Grade - 9 .

AlladinOne [14]

Answer:

Step-by-step explanation:

Commission for amount Rs. 5,00,00 = $\frac{2}{100}*500000$

= 2* 5000

= Rs. 10,000

total commission = Rs. 32,000

Remaining commission = 32500 - 10000

= Rs. 22500

Let remaining amount of the restaurant = Rs. x

Commission on Rs. x = 22500

3% of x = 22500

$\frac{3}{100}*x=22500\\\\x=22500*\frac{100}{3}\\\\x = 7500*100$

x = Rs. 750000

Price of the restaurant = 750000 + 500000

=Rs . 1250000
