Answer:
[tex]\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}[/tex]
The last option matches the correct solution
Step-by-step explanation:
Equation Solving
We have the following equation:
[tex]\displaystyle V=\frac{4}{3}\pi r^3[/tex]
And it's required to solve it for r.
Solving this equation needs to perform some operations to have the r isolated from any other variables or constants.
It can be done by conveniently operating on both sides as follows:
Eliminate the denominator by multiplying by 3:
[tex]\displaystyle 3V=4\pi r^3[/tex]
Move [tex]4\pi[/tex] to the other side by dividing by [tex]4\pi[/tex]:
[tex]\displaystyle \frac{3V}{4\pi}= r^3[/tex]
Swapping sides to have r at the left side:
[tex]\displaystyle r^3=\frac{3V}{4\pi}[/tex]
Finally, take the cubic root and leave r alone:
[tex]\displaystyle r=\sqrt[3]{\frac{3V}{4\pi}}[/tex]
The last option matches the correct solution

Which of the equations below can be solved by square roots? How would you solve the other equation? Explain your reasoning. Give the solutions to both equations. Equation A: x? - 9x = 0 Equation B : x2-9=0
Answer:
Equation A is factoring, x=9 and x=0
Equation B is the square root, x=3
The equation A: x² - 9 = 0 can be solved by square root method
The equation B: x² - 9x = 0 can only be solved by factoring
The given equations are:
Equation A: x² - 9x = 0
Equation B: x² - 9 = 0
The equation x² - 9 can be rewritten as:
x² - 3² = 0
This is a difference of two squares which can be further expressed as:
(x - 3)(x + 3) = 0
x - 3 = 0
x = 3
x + 3 = 0
x = -3
This shows that the equation x² - 9 = 0 has two roots x = -3 and x = 3
Also, from x² - 9 = 0
[tex]x = \pm\sqrt{9} \\\\x = \pm3[/tex]
For the equation x² - 9x = 0
This can be factored as x(x - 9) = 0
x = 0, x = 9
This is not solved by the square root method.
Therefore, the equation x² - 9 = 0 can be solved by square root method

A rental car company is running two specials. Customers can pay $50 to rent a compact car
for the first day plus $6 for each additional day, or they can rent the same car for $20 the
first day and $12 for every additional day beyond that. Nora notices that, given the number
of additional days she wants to rent the car for, the two specials are equivalent. How many
additional days does Nora want?
Write a system of equations, graph them, and type the solution
Answer:
After 5 additional days it will be equal
Step-by-step explanation:
1st special: 6x + 50
2nd special: 12x + 20
6x + 50 = 12x + 20
Subtract 20 from both sides;
6x + 30 = 12x
Subtract 6x from both sides;
30 = 6x
Divide both sides by 6;
x = 5

Step-by-step explanation: The x-intercept is
the point where a line crosses the x-axis.
So the x-intercept for the line on the graph is (7, 0).
All x-intercepts have a y-coordinate of zero.
The y-intercept is a point where a line crosses the y-axis.
So the y-intercept for the line on the graph is (0, 5).
All y-intercepts have a x-coordinate of zero.
I don't understand this
Answer:
y=2/3x+3
Step-by-step explanation:
First, you would use the point slope formula : y₂-y₁/x₂-x₁
(5--3)/(3--9)
=8/12
=2/3
Then you would plug it back into the equation along with one of the points. Ex:
-3=2/3(-9)+b
-3=-6+b
3=b
So in conclusion, the formula would come out to y=2/3x+3

Which situation best describes a positive correlation? Group of answer choices The height of a candle and the amount of time it stays lit. The price of a pizza and the number of toppings added. The temperature of a cup of hot chocolate and the length of time it sits. The amount of rainfall on Fridays.
Answer:
The correct option is;
The price of a pizza and the number of toppings added
Step-by-step explanation:
A positive correlation is one in which the variables being correlated, progress in the same direction, such that an increase in one variable will lead o an increase in the other variable;
The price of a pizza depends on the size of the pizza and the price increases for each additional topping added, such that the price of the pizza will increase as the number of toppings is increased
The variable, the height of the candle and the variable, the length of time it stays on, are positively correlated because, the two variables depends on each other whereby the time it takes to completely burn a candle increases as the length of the candle increases, however, the candle can be put out depending on usage, even if it can stay lit for a longer period of time.
12. The second of three numbers is one less than the first. The third
number is 5 less than twice the second. If the third number exceeds the
first number by 12, find the three
numbers.
Answer:
The three numbers are 19, 18, and 31.
Step-by-step explanation:
The three numbers are x, y, and z.
y=x-1
z=2y-5
z=x+12
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
y=18
z=31
The three numbers are 19, 18 and 31
what is Algebra?Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions.
let the three numbers be x, y, and z.
So, according to question
The second of three numbers is one less than the first,
y = x-1
The third number is 5 less than twice the second,
z=2y-5
also, If the third number exceeds the first number by
12z=x+12
Now, equating the equations
2y-5=x+12
2(x-1)-5=x+12
2x-2-5=x+12
x=19
So, y=18 and z=31.

Answer:

Step-by-step explanation:
(3/5k)-5=7/10k
we multiple both sides by 10k to get only one k
10k(3/5k)-5 = 7
(30k/5k)-5 =7 now we add 5 to other side and simplify our k fraction

*x=4,y=-3
*x=-5,y=2
*x=4,y=3
please answer step by step
Answer: x=4 and y=-3
Step-by-step explanation:
To use elimination to solve system of equations, you want to make sure the equations are first in standard form.
2x+4y=-4
3x+5y=-3
We want to make sure either the x or the y are equal so we can eliminate them. Let's eliminate x.
2x+4y=-4 [multiply equation by 3]
3x+5y=-3 [multiply equation by 2]
6x+12y=-12
6x+10y=-6
We can now subtract the equations.
2y=-6 [divide both sides by 2]
y=-3
Now that we know y=-3, we can plug it into an equation to solve for x.
2x+4y=-4 [plug in y=-3]
2x+4(-3)=-4 [multiply]
2x-12=-4 [add both sides by 12]
2x=8 [divide both sides by 2]
x=4
The final answer is x=4 and y=-3.

A gardener is installing fence around his garden. Let x represent the width of the garden, in feet. The perimeter of the garden is 8x + 8. Which expression represents the length of the garden?
1. 2x + 2
2. 3x + 4
3. 6x + 8
4. 8x + 8 – 2x
Answer:
2. 3x + 4
Step-by-step explanation:
What we know:
w=x
Perimeter (p) = 8x+8
Formula for perimeter p =2(L+W)
8x+8 = 2(L+W)
L+W is half, so
L+W = 4x+4
Substract W on both sides;
L = 4x+4 -W
We know that W = x
So
L= 4x+4-x
4x-x= 3x
L= 3x+4
Two rival dry cleaners both advertise their prices. Store A's prices are modeled by the expression 30x - 8, where x is the number of items brought in. Store B's prices are modeled by the expression 6(5x + 3), where x is the number of items brought in. When do the two stores charge the same rate?
Store A's prices are represented by the expression 15x - 2.
Store B's prices are represented by the expression 3(5x + 7).
To find when the 2 stores charge the same rate , we set the expression equal and solve for x
15x - 2 = 3(5x+7)
15x -2 = 15x + 21
Subtract 15x on both sides
-2 = 21
We cannot solve for x
So , the price of two stores never be same
Two stores never charge the same rate
