What is the answer to this???

Answer:

5/4

Step-by-step explanation:

The slope intercept form for a linear equation is y = mx + b. The variable's (x) coefficient, which is represented as m, is the slope of any linear equation.

Answer:

The volume of the sphere is 20 m

Step-by-step explanation:

Given

Solid Shapes: Cylinder and Sphere

Volume of the cylinder [tex]= 30m^3[/tex]

Required

Volume of the sphere

First, we need to calculate the radius of the cylinder

The formula goes thus

[tex]V = \pi r^2h[/tex]

By substituting 30 for V, we have

[tex]30 = \pi r^2h[/tex]

Divide through by h

[tex]\frac{30}{h} = \frac{\pi r^2h}{h}[/tex]

[tex]\frac{30}{h} = \pi r^2[/tex]

Calculating the volume of the sphere

The formula goes thus

[tex]V = \frac{4}{3}\pi r^3[/tex]

Expand Expression

[tex]V = \frac{4}{3} * \pi r^2 * r[/tex]

Substitute [tex]\frac{30}{h} = \pi r^2[/tex]

[tex]V = \frac{4}{3} * \frac{30}{h} * r[/tex]

Simplify Expression

[tex]V = \frac{4}{1} * \frac{10}{h} * r[/tex]

[tex]V = \frac{40}{h} * r[/tex]

Given that the height of the cylinder and the sphere are equal

This means that the height of the cylinder equals the diameter of the sphere.

Mathematically; This is represented by

h = D

Where D represents diameter of the sphere

Recall that D = 2r (2 * radius)

Substitute 2r for D

h = 2r

Substitute h = 2r in [tex]V = \frac{40}{h} * r[/tex]; This gives

[tex]V = \frac{40}{2r} * r[/tex]

[tex]V = \frac{40r}{2r}[/tex]

[tex]V = 20[/tex]

Hence, the volume of the sphere is 20 m

Answer:

x = 2,  y=3

Step-by-step explanation:

3x + y = 9

5x + 4y = 22

Multiply the first equation by -4

-4(3x + y) = 9*-4

-12x -4y = -36

Add this to the second equation to eliminate y

-12x -4y = -36

5x + 4y = 22

---------------------------

-7x    = -14

Divide each side by -7

-7x/-7 = -14/-7

x = 2

Now find y

3x+y = 9

3(2) +y = 9

6+y = 9

Subtract 6 from each side

-6+6 +y = 9-6

y = 3

Answer:

x = 2, y = 3

Step-by-step explanation:

3x + y = 9 (1)

5x + 4y = 22 (2)

Multiply equation (1) by -4 and add to equation (2)

-12x - 4y = -36

5x + 4y = 22

-7x = -14

x = 2

Using any equation, solve for y

5(2) + 4y = 22

4y = 12

y = 3

Answer:

The side length is 2 ft

Step-by-step explanation:

A cube has a volume of

V = s^3

8 = s^3

Take the cube root of each side

8 ^ 1/3  = s^3 ^1/3

2 = s

Answer:

x=20

Step-by-step explanation:

73-13=60

60÷3=20

Answer:

x = 20

Step-by-step explanation:

3x + 13 = 73

3x = 73 - 13

3x = 60

x = 60 : 3

x = 20

Answer:

-10x-3y-6

Step-by-step explanation:

All you have to do is just combine the like terms, or the numbers with the same variables attached.

Combine all of the numbers with x-values.

Combine all the numbers with the y-values.

And combine all of the numbers with no variables.

Answer: 1. $3.85

2. $1.55

3. 7/12

Step-by-step explanation:

1. Since you are finding out price PER gallon, you would divide $46.20 by 12 because Jayden bought 12 gallons.

2. Since they give you the price per gallon and the amount bought in this problem, you will multiply 1.2 and $1.29. Think of this as if you were buying 5 apples and each cost $1, you would do 5 x 1 to find the total cost. The same concept applies here.

3. To add 1/4 and 1/3 you would find a common denominator. The common denominator would be 12.  1/4 = 3/12 and 1/3 = 4/12. Now you can add them together, 3/12 + 4/12 = 7/12

Answer: Choice A) the total number of atoms cannot change during a reaction

Matter cannot be created or destroyed. Instead, matter can be rearranged from one form to another. For example, boiling water turns the liquid into gas (steam) when it evaporates. The H2O molecules haven't been created or destroyed.

Since this question is asking for an inequality formula, let's get started.

Seven subtracted from c=c-7  (it is NOT 7-c because then it would ask c subtracted by seven)

Less than means that the c-7 is less than -16, so it would face this way <

The final answer is c-7<-16

Answer:

Step-by-step explanation:

(-4,0) ; (-7, -14)

[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}\\\\ =\sqrt{(-7-[-4])^{2}+(-14-0)^{2}}\\\\ =\sqrt{(-7+4)^{2}+(-14)^{2}}\\\\=\sqrt{(-3)^{2}+(-14)^{2}}\\\\=\sqrt{9+196} \\\\=\sqrt{205} \\\\=14.3178[/tex]

Answer:

90

Step-by-step explanation:

a)

Since, to find the average of a set of numbers, you need to add them all together and divide by the amount of numbers:

[tex]\dfrac{86+83+81+x}{4}=85[/tex]

b)

Multiply both sides by 4:

[tex]86+83+81+x=340\\x=90[/tex]
