Simplify 6x3+5x2+3-4(x3-3x2+2)

1 answer:

7 0

The answer I got was 21 because 6x3=18 5x2=10 3-4=-1 and -1x3=-3
-3 x 2=-6 and the +2 so you would have
18+10+-3+-6+2
28+. -3+-6+2
25+-6+2
19+2
21

Answer:

1,000 gallons of water each pump can transfer in 1 second.

Step-by-step explanation:

Given:

The dam has 12 pumps that each transfer the same amount of water through pipes from Lake Roosevelt to Banks Lake.

Together, the pumps can transfer about 12,000 gallons of water each second.

Now, to find the gallons of water each pump can transfer in 1 second.

Number of pumps the dam has = 12.

Gallons of water all pumps can transfer in 1 second= 12,000.

As given, each pumps transfer the same amount of water through pipes.

Now, to get the gallons of water each pump can transfer in 1 second we divide gallons of water all pumps can transfer in 1 second by the number of pumps the dam has:

$\frac{Gallons\ of\ water\ all\ pumps\ can\ transfer\ in\ 1\ second\ }{ Number\ of\ pumps\ the\ dam\ has}$

$=\frac{12,000}{12}$

$=1,000\ gallons.$

Therefore, 1,000 gallons of water each pump can transfer in 1 second.

The diagram shows a triangle. 490 880 What is the value of v? V =

Step2247 [10]

Answer:

43°

Step-by-step explanation:

The first thing you should do is make the equation. We should know that the sum of all the angles is 180. So it should look like this...

$49+88+x=180$

Combine like terms:

$137+x=180$

Subtract the 137 on both sides:

$x= 43$

That's it the value of v is 43°.

Answer:

Hydrostatic Force = 35.28KN

Step-by-step explanation:

To solve this question, let's consider integrating the hydrostatic force from the top of the triangle to the bottom.

Formula for a thin horizontal slice of the triangle the force is;

δF=ρgxwδx

Where w is width of triangle; ρ is density of water and g is acceleration due to gravity

At depth x, the width of the triangle is w=2/3x.

Thus, F = (3,0)∫)ρgxwδx

=(2/3)ρg[(3,0)∫)x²δx]

= integrating, we have;

F = (2/3)ρg[(3³/3) - (0³/3)]

F = (2/5)ρg [27/3] = (2/5)(1000)(9.8)(9) = 35280 N = 35.28 KN
