What is the answer for -2x = 34

Hunter-Best [27]

To solve:

-2x = 34
----- -----
-2 -2

(-2x means -2 times x, so to undo this we need to divide by -2 on both sides)

x = -17

Then you do basic division (knowing that a positive divided by a negative results in a negative answer). And that's it!

The city council plans to build a new water storage tank for the community. The tank is cylindrical with a base diameter of 25 f

Stella [2.4K]

Answer:

a. $14726.216ft^{3}$

b. $110446.62gal$

Step-by-step explanation:

I attach the diagram of the new water tank.

a. In order to find the volume of the tank in cubic feet, we will need to calculate the volume of a cylinder. We know that its base measures $25ft$ and its height is $30ft$ .

The volume ''V'' of a cylinder is :

$V=(\frac{\pi D^{2}}{4}).(H)$

Where '' $D$ '' is the diameter of the base and '' $H$ '' is the height of the cylinder.

If we replace all the data in the equation :

$V=\frac{\pi .(25ft)^{2}}{4}.(30ft)=14726.216ft^{3}$

We found out that the volume of the tank in cubic feet is $14726.216ft^{3}$

b. We know that 1 cubic foot of water is equal to 7.5 gallons. To find the amount of gallons that the new tank can hold, we need to do an unit conversion.

This equivalence is given to us :

$1ft^{3}=7.5gal$ ⇒ Using the equivalence ⇒

$(14726.216ft^{3}).(\frac{7.5gal}{1ft^{3}})=110446.62gal$

Finally, the new tank will hold $110446.62gal$ of water.

Solve for p. 50,000= (25,000*p)/(100-p)

galben [10]

If
50000=25000*p/(100-p)
50000(100-p)=25,000p
5,000,000-50,000p=25,000p add the 50,000
5,000,000=50,000p+25,000p
5,000,000=75,000p
p=5,000,000/75,000
p=66.66
