Pete has an old playstation that he bought for $400.
katrin2010 [14]

Answer:

1 year= $280

Step-by-step explanation:

30% of 400= 0.3 * 400= 120

400-120= 280

after one year the playstation cost 280

30% of 280= 0.3 * 280= 84

280-84= 196

after 2 years it cost $196

multiply the number by 0.3 to get 30% of the total

PLEASE HELP!!!<br> EQUATIONS!!! ASAP :)
mel-nik [20]
1)solve for y.

4x+y=7

Add -4x to both sides.

4x+y+−4x=7+−4x

y=−4x+7



2) solve for y.

y−5x=9

Add 5x to both sides.

−5x+y+5x=9+5x

y=5x+9



3) solve for y.

3y−15x=12

Add 15x to both sides.

−15x+3y+15x=12+15x

3y=15x+12

Divide both sides by 3.

3y/3=15x+12/3

y=5x+4




4) solve for y.

8x+2y=18

Add -8x to both sides.

8x+2y+−8x=18+−8x

2y=−8x+18

Divide both sides by 2.

2y/2=−8x+18/2

y=−4x+9
 



5 ) solve for y.

7x−y=35

Add -7x to both sides.

7x−y+−7x=35+−7x

−y=−7x+35

Divide both sides by -1.

−y/−1=−7x+35/−1

y=7x−35



6)  solve for y.

4x+1=9+4y

Flip the equation.

4y+9=4x+1

Add -9 to both sides.

4y+9+−9=4x+1+−9

4y=4x−8

Divide both sides by 4.

4y/4=4x−8/4

y=x−2



7)  solve for x.

y=5x−2x

Flip the equation.

3x=y

Divide both sides by 3.

3x/3=y/3

x=1/3y



8) solve for x.

r=x+9x

Flip the equation.

10x=r

Divide both sides by 10.

10x/10=r/10

x=1/10r



9) solve for x.

b=3x+9xy

Flip the equation.

9xy+3x=b

Factor out variable x.

x(9y+3)=b

Divide both sides by 9y+3.

x(9y+3)/9y+3=b/9y+3

x=b/9y+3



10)  solve for x.

w=2hx−11x

Flip the equation.

2hx−11x=w

Factor out variable x.

x(2h−11)=w

Divide both sides by 2h-11.

x(2h−11)/2h−11 = w/2h−11

x=w/2h−11
 

11) solve for x.

p=4x+qx−5

Flip the equation.

qx+4x−5=p

Add 5 to both sides.

qx+4x−5+5=p+5

qx+4x=p+5

Factor out variable x.

x(q+4)=p+5

Divide both sides by q+4.

x(q+4)/q+4=p+5/q+4

x=p+5 / q+4




12) solve for x.

m=9+3x−dx

Flip the equation.

−dx+3x+9=m

Add -9 to both sides.

−dx+3x+9+−9=m+−9

−dx+3x=m−9

Factor out variable x.

x(−d+3)=m−9

Divide both sides by -d+3.

x(−d+3)/−d+3=m−9/−d+3

x=m−9/−d+3

What is the volume of the sphere?
nataly862011 [7]

The volume of the sphere in the given image, to the nearest tenth, is: 2,143.6 cm³.

<h3>How to calculate the Volume of a Sphere?</h3>

A sphere is a solid shape that is round. The volume of a sphere is the amount of space it contains, which is calculated by the formula expressed as:

Volume = 4/3 × π × r³, where r is the radius of the sphere.

The parameter of the sphere is given below:

Radius of the sphere (r) = 8 cm.

π = 3.14

Substitute r = 8 into 4/3 × π × r³ to find the volume of the sphere

Volume of the sphere = 4/3 × π × r³ = 4/3 × 3.14 × 8³

Volume of the sphere = 4/3 × 3.14 × 512

Volume of the sphere = (4 × 3.14 × 512)/3

Volume of the sphere = (6,430.72)/3

Volume of the sphere = 2,143.6 cm³

In summary, the volume of the sphere in the given image, to the nearest tenth, is: 2,143.6 cm³.
