The minimum amount of water she needs to completely fill the sphere is; 904.32 inches³

The formula for Volume of a Sphere is given as;

V = ⁴/₃πr³

We are given;

Diameter; d = 12 inches

Thus;

Radius; r = 12/2 = 6

To get the minimum amount of water she needs to completely fill the sphere, we just plug in the relevant values into the volume equation to get;

V = ⁴/₃π(6)³

Answer:

[tex]M^{2}=3.2[/tex]

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form [tex]y*x=k[/tex] or [tex]y=k/x[/tex]

In this problem we have

[tex]P*M^{2}=k[/tex]

step 1

Find the value of k

For P=8, M=2

substitute

[tex]k=(8)(2)^{2}=32[/tex]

The equation is equal to

[tex]P*M^{2}=32[/tex]

step 2

Find the value of M²

when P=10

substitute the value of P in the equation

[tex]10*M^{2}=32[/tex]

[tex]M^{2}=3.2[/tex]

Answer:

x²+2xy-x+y²-y-12

Step-by-step explanation:

(x+y+3)(x+y-4)

= x(x+y-4)+y(x+y-4)+3(x+y-4)

= x²+xy-4x+xy+y²-4y+3x+3y-12

= x²+2xy-x+y²-y-12

The answer is:

The simplified expression is:

[tex](x + y + 3)(x + y - 4)=x^{2} +y^{2} +2xy-x-y-12[/tex]

To solve the problem,  we need to remember how to use the distributive property and how to add like terms.

The distributive property can be defined as follow:

[tex](a+b)(c+d)=ab+ad+bc+bd[/tex]

The like terms are the terms that share the same variable and the same exponent, for example:

[tex]3x+x+ x^{2}=x^{2} +4x[/tex]

We were able to add the first and the second term because they share the same variable and the same exponent.

Now, we are given the expression:

[tex](x+y+3)(x+y-4)[/tex]

So, simplifying we have:

[tex](x + y + 3)(x + y - 4)=(x*x)+(x*y)-(4*x)+(y*x)+(y*y)-(4*y)+(3*x)+(3*y)-(3*4)\\\\(x + y + 3)(x + y - 4)=x^{2} +xy-4x+xy+y^{2}-4y+3x+3y-12\\\\(x + y + 3)(x + y - 4)=x^{2} +y^{2} +2xy-x-y-12[/tex]

Hence, we have that the simplified expression is:

[tex](x + y + 3)(x + y - 4)=x^{2} +y^{2} +2xy-x-y-12[/tex]

Answer: W=-1.8

Step-by-step explanation:

Divide both sides by 2.02 and you are left with W=-1.8.

Answer:

W = -1.8

Step-by-step explanation:

Step 1: Divide 2.02 on both sides.

W = -1.8

She could've subtracted 19 from both sides of the equation in the second step to find the value of [tex]x[/tex] immediately, rather then add 19 to both sides.

1                                16 + (16/4) = 20

2                                20 + (20/4 ) = 20 + 5 = 25

3                                25 + (25/4 ) = 25 + 6.25 ≈ 31

4                                31 + (31/4) = 31 + 7.75 ≈ 31+8 ≈ 39

5                                39 + (39/4) = 39 + 9.75 ≈ 39 + 10 ≈ 49

6                                 49 + (49/4) =  49+ 12.25 ≈ 49+12 ≈ 61

7                                 61 + (61/4) = 61 + 15.25 ≈ 61 + 15 ≈ 76

Answer:

17. Scale Factor is  3:1

18. Scale Factor is  1:3

Step-by-step explanation:

Scale Factor: In two similar shapes, the ratio of their corresponding sides is called scale factor.

17. Give the scale factor of Figure A to Figure B

Figure A has sides:

Hypotenuse = 15

Perpendicular = 12

Base = 9

Figure B has sides:

Hypotenuse = 5

Perpendicular = 4

Base = 3

So, if we divide all sides of figure A by 3 we get Figure B

So, Figure A : Figure B

3:1

18. Give the scale factor of Figure B to Figure A

Figure B has sides:

Hypotenuse = 5

Perpendicular = 4

Base = 3

Figure A has sides:

Hypotenuse = 15

Perpendicular = 12

Base = 9

If we multiply 3 with the sides of Figure B we can get the sides of Figure A.

So scale factor is 3.

So, Figure B : Figure A

1:3

Answer:

17) 3 : 1

18: 1 : 3

Step-by-step explanation:

Figure A and Figure B are similar triangle.

Scale Factor of A : B

= 9 : 3

= 3 : 1

Scale Factor of B : A

= 3 : 9

= 1 : 3

10.50+4.50x=46.50

This is the fuction to use to solve the problem.

The function that can be used to find the number of rides he went on is

46.50 = 4.5x + 10.50

A linear equation is a mathematical expression involving variables raised to the first power only.

It takes the form ax+b=0, where

a and b are constants, and x is the variable.

Represent the number of rides he went on by x

the total amount on rides will be

4.5x

The entrance fee = $10.50

Total amount = 45x + 10.50

Therefore, the equation that represents the number of rides he went on is

46.50 = 45x + 10.50.

Answer:

83.33%

Step-by-step explanation:

We first need to evaluate 80% of the first 15 matches in order to determine the number of watches out of 15 which they won.

80 % of 15 = 80/100 * 15 = 12

12 matches out of the first 15 were won.

Since the team won the rest of the 3 remaining matches, the total number of matches won becomes;

12 + 3 = 15

The team thus won 15 matches out of a total of 15 + 3 =18 matches .

The percent of all matches won is ;

15/18 * 100 = 83.33%

"between 30 yards and 150 yards"

Step-by-step explanation:

Let one side of a triangle be x and another side be y. To find the possible lengths of the third side, it is given by:

Possible length of 3rd side would be between "x - y" and "x + y"

Here, given x = 90 and y = 60, so the possible length of 3rd side would be:

90 - 60 = 30,

90 + 60 = 150

Hence, in between 30 and 150

Step-by-step explanation:

Look at the picture.

ΔACD it's a triangle 30° - 60° - 90°. The sides are in ratio 1 : √3 : 2.

Therefore

CD : CB : DB = 1 : √3 : 2.

If BC = 16, then CD = 16 : 2 = 8 and CB = 8√3

ΔABC it's a triangle 45° - 45° - 90°. The sides are in ratio 1 : 1 : √2.

Therefore

AC : AB : CB = 1 : 1 : √2

If CB = 8√3, then AB = x = (8√3)/(√2)

Step-by-step explanation:

The equation of an ellipse with a center at origin, a height of 12 units, and a width of 19 units is x^2/(9.5^2) + y^2/(6^2) = 1.

The student is asking for an equation of an ellipse. An ellipse has a standard form equation given by x^2/a^2 + y^2/b^2 = 1, where 'a' is the semi-major axis and 'b' is the semi-minor axis. The semi-major axis and the semi-minor axis are half of the major axis (width) and minor axis (height) respectively. Here, the width or major diameter of the ellipse is given as 19 units and the height or minor diameter as 12 units.

Thus, the semi-major axis is 19/2 = 9.5 and the semi-minor axis is 12/2 = 6. As the ellipse's center is at the origin, the equation of the ellipse is given by: x^2/(9.5^2) + y^2/(6^2) = 1.

https://brainly.com/question/33868440

#SPJ12

The equation of the ellipse in standard form with a center at the origin, a height of 12 units, and a width of 19 units is x²/(19/2)² + y²/(6)² = 1.

The equation of an ellipse in standard form with the center at the origin is given by x²/a² + y²/b² = 1, where a is the semimajor axis (half the width) and b is the semiminor axis (half the height).

Given a width of 19 units and a height of 12 units, the semimajor axis will be half of the width and the semiminor axis will be half of the height. So, the equation of the ellipse will be x²/(19/2)² + y²/(12/2)² = 1.

Simplifying, x²/(19/2)² + y²/(6)² = 1. This is the equation of the ellipse in standard form with a height of 12 units and a width of 19 units.

Case 1: [tex]4x-3>0[/tex]

[tex]4x-3=20[/tex]

Solve for the variable "x", therefore you get:

[tex]4x=20+3\\\\x=\frac{23}{4}[/tex]

Case 2: [tex]4x-3<0[/tex]

[tex]-4x+3=20[/tex]

Solve for the variable "x". Then, you  get:

[tex]-4x=20-3\\\\x=\frac{17}{-4}\\\\x=-\frac{17}{4}[/tex]
