Got this online. Pour the distilled water in the beaker until it is half full. Add 3 tbsp. of salt to the water and mix until completely dissolved.

Insert the two electrodes into the salt water. They should be on either side of the beaker. Once this is done, the light bulb should light up.

Answer:

The value 4.5 is rational and the value 15−−√ is irrational. The sum of 4.5 and 15−−√ has a non-repeating and non-terminating decimal expansion. Therefore, the sum of 4.5 and 15−−√ is irrational. I can't explan but that's the correct Answer

Solve T= C(7+AB) for A

Tcecarenko [31]

T= C(7+AB)

T = 7C + ABC

T - 7C = ABC

(T - 7C)/BC = A

Three times a larger number is 30 more than 5 times a smaller number. The sum of the larger number and 5 times the smaller numbe

snow_tiger [21]

3y = 5x+30 , y+5x = 50

using elimination method ...

3y-5x=30
+ y+5x=50
——————
4y = 80
y= 20

so using one of the original equations..

20 + 5x = 50
5x = 30
x =6

x = 6
y = 20

Rounded to the nearest hundred cubic meters, what is the total capacity (cone and cylinder) of the storage container?

hichkok12 [17]

The picture in the attached figure

we know that
the total capacity of the storage container=volume of a cone+volume of cylinder

step 1
find the volume of a cone
volume of a cone=(1/3)*pi*r²*h
r=6 m
h=8 m
so
volume=(1/3)*pi*6²*8-----> 301.44 m³

step 2
find the volume of the cylinder
volume of a cylinder=pi*r²*h
r=6 m
h=10 m
s6
volume=pi*6²*10----> 1130.40 m³

total volume=301.44+1130.4-----> 1431.84 m³-------> 1400 m³

the answer is
1400 m³
