8(4u-1)-12u = 11(2u-6)

32u-8-12u = 22u-66

20u-8 = 22u-66

22u-20u = 66-8

2u = 58

u = 29

Pls help ASAP first correct answer gets brainleist ​
AnnZ [28]

Answer:

4.58257569 meters (Could probably get away with rounding it to 4.6 meters)

Step-by-step explanation:

Pythag theorem

a^2 +b^2 =c^2

Insert your numbers

10^2+b^2=11^2

Simplify squares

100+b^2=121

subtract 100 from both sides

b^2=21

sqrt both sides

sqrt(b^2)=sqrt(21)

simplify sqrts to get b

b= 4.58257569

A rectangle container that has a length of 30 cm,a width of 20 cm,and a height of 24 cm is filled with water to a depth of 15 cm
Ket [755]
<span>V(h 24) = 30 cm*20 cm*24 cm = 14400 cm³ =  14,4 liters</span>
<span>V(h 15) = 30 cm*20 cm*15 cm =    9000 cm³  =  9 liters</span>
<span>                         + 6,5 liters = + 6500 cm³      </span>
9 liters +   6,5 liters = 15,5 liters         =>   15,5 liters -14,4 liters = 1,1 liters
now  15500 cm³   =>    1100 cm³ =1,1 liters  too much !!
Answer:  1,1 liters of water overflow the container.<span>
