I need an answer to this big question
Kisachek [45]

Answer:

RS + ST = RT

23 - 2x     +     9x - 5     =     39

18 + 7x = 39

7x = 39 - 18 = 21

x= 21/7

x = 3

RS = 23 - 2x (given)

RS = 23 - 2(3)

     = 23 - 6

RS = 17

Find an equation of the sphere with points P such that the distance from P to A(−3, 4, 4) is twice the distance from P to B(6, 3
NeX [460]

Answer:

Therefore, we conclude that the center of sphere at point

(27/3, -8/3, -8/3) with a radius 6.89.

Step-by-step explanation:

We have the formula for distance, we get

\sqrt{(x+3)^2+(y-4)^2+(z-4)^2} =2· \sqrt{(x-6)^2+(y-3)^2+(z+1)^2}

(x+3)^2+(y-4)^2+(z-4)^2=4·[(x-6)^2+(y-3)^2+(z+1)^2]

x²+6x+9+y²-8y+16+z²-8z+16=4x²-48x+4y²-24y+4z²+8z+184

3x²+3y²+3z²-54x+16y+16z=-143

(x²-54x/3)+(y²+16y/3)+(z²+16z/3)=-143/3

(x²-54x/3+729/9)+(y²+16y/3+64/9)+(z²+16z/3+64/9)=-143/3+729/9+2·64/9

(x-27/3)²+(y+8/3)²+(z+8/3)²=428/9

We calculate a radius \sqrt{428/9} =6.89

Therefore, we conclude that the center of sphere at point

(27/3, -8/3, -8/3) with a radius 6.89.

During a rain shower, Jeanette collects 42 1 2 gallons of water in a rain barrel outside her home. She uses 1 1 4 gallons to wat
DerKrebs [107]

Answer:

492 gallons

Step-by-step explanation:

Total gallons of water collected = 4212

Gallons used for watering of plants = 114

Remaining gallons = 4212 - 114

                               = 4098

She uses 12% of the remaining water to was her laundry.

So that, gallons of water used to wash her laundry = 12% of 4098

                                                                                     = \frac{12}{100} × 4098

                                                                     = 491.76

                                                                     ≅ 492

She uses 492 gallons to wash her laundry.
