Write an equation for the amount of money, , that will be collected if boxes of chocolate bars are sold. Which is the independent variable and which is the dependent variable
Answer:
Kindly check explanation
Step-by-step explanation:
Let amount of money = C
If the number of chocolate bars sold = x
Let cost per chocolate bar = p, since cost per bar isn't stated
Amount of money that will be collected :
C(x) = P * x
The dependent variable is the Amount of money that will be collected as the amount of money depends on the number of chockate bars sold
The number of chocolate bars sold us the independent variable as it dictates the amout of money to be collected, hence it is the predictor variable.
A taxi cab cost $1.75 for the 1st mile and .75 for each additional mile you have $20 to spend on your ride was in a quality could be certified and how many miles you can travel if N is a number of additional miles
Answer: 0.75n+1.75 ≤ 20 because you have to have the number of additional miles with the cost of $0.75 per mile but then you have to add the original first mile with a cost of $1.75. It has to be less than or equal to because you only have $20 to spend you can't spend more than that you have to spend that amount or less.

What is the value of tangent theta in the unit circle below? One-half StartFraction StartRoot 3 EndRoot Over 3 EndFraction StartFraction StartRoot 3 EndRoot Over 2 EndFraction StartRoot 3 EndRoot
Answer:
[tex]\frac{1}{\sqrt{3} }[/tex]
Step-by-step explanation:
A unit circle is defined as a circle of unit radius (that is the radius of the circle is equal to 1). In trigonometry, the unit circle is a circle with a radius of 1, while centered at the origin (0, 0) in the Cartesian coordinate.
In the unit circle below, we can see that the line touches the unit circle at point [tex](\frac{\sqrt{3} }{2} ,\frac{1}{2})[/tex], therefore to find the tangent of theta, we use the formula:
[tex]tan\theta = \frac{y}{x} \\\\tan\theta=\frac{\frac{1}{2} }{\frac{\sqrt{3} }{2} } =\frac{1}{2}*\frac{2}{\sqrt{3} } \\\\tan\theta=\frac{1}{\sqrt{3} }[/tex]

Tristan paid $17.50 to buy 2 pounds of peanuts and 3 pounds of cashews. Rivka paid $19.00 to buy 5 pounds of peanuts and 2 pounds of cashews. If both people paid the same price per pound, what was the price per pound for the cashews?
A. $2.00
B. $3.80
C. $4.50
D. $8.75
Answer:
C. $4.50
Step-by-step explanation:
hello, there.
1) 2p + 3c = 17.50
2) 5p + 2c = 19.00
:
Solve equation 1 for p
:
p = (17.50 - 3c) / 2
:
Substitute for p in second equation
:
(5(17.50 - 3c) / 2) + 2c = 19.00
:
Multiply both sides of = by 2
:
(5(17.50 - 3c)) + 4c = 38.00
:
87.50 - 15c + 4c = 38.00
:
-11c = -49.50
:
c = 4.50
:
---------
Cashews are $4.50 per pound
--------------
:have a great day.
Answer:
C
Step-by-step explanation:
Let p represent the cost for one pound of peanuts and let c represent the cost for one pound of cashews.
Two pounds of peanuts and three pounds of cashews cost $17.50. So:
[tex]2p+3c=17.5[/tex]
Five pounds of peanuts and two pounds of cashews cost $19.00. So:
[tex]5p+2c=19[/tex]
This yields a system of equations.
We can solve this using elimination. We can multiply the first equation by -5, and the second by 2. Therefore:
[tex]-5(2p+3c)=-5(17.5)[/tex]
Multiply:
[tex]-10p-15c=-87.5[/tex]
And:
[tex]2(5p+2c)=2(19)[/tex]
Multiply:
[tex]10p+4c=38[/tex]
Now, we can add the two equations together:
[tex](-10p-15c)+(10p+4c)=(-87.5+38)[/tex]
Combine like terms:
[tex]-11c=-49.5[/tex]
Therefore:
[tex]c=4.5[/tex]
So, a pound of cashews costs $4.50.
Our answer is C.
Notes:
To solve for the cost for peanuts, we can use the first (or second equation) again:
[tex]2p+3c=17.5[/tex]
Substitute:
[tex]2p+3(4.5)=17.5[/tex]
Solve for p:
[tex]2p+13.5=17.5\Rightarrow 2p=4\Rightarrow p=2[/tex]
So, a pound of peanutes cost $2.00.

Find the value of x in the figure shown.
can someone help me with this and show me the steps if you don't mind
Answer:
(x+8)(x+5)
Step-by-step explanation:
Since we know x2 is equivalent to x times x we can automatically start by filling in the first two spaces with x. Then since we know that we're going to need two numbers that equal forty since it's part of the equation we can get two number that will also add up to 13x which is 8 and 5. We then get (x+8)(x+5).

The only system of equation (A) has a y-value of 0.
What are Systems of equations?Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.
There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.
To find the solution with a y-value of 0, we need to substitute y=0 in each equation of the system and solve for x.
(A) x + 2y = -1
x + 2(0) = -1
x = -1
y = 3x + 3
y = 3(-1) + 3
y = 0
The solution to system A has a y-value of 0.
(B) 3x - y = 2
3x - 0 = 2
x = 2/3
x + 2y = -1
(2/3) + 2y = -1
2y = -1 - (2/3)
2y = -5/3
y = -5/6
The solution to system B does not have a y-value of 0.
(C) y = 3x + 3
y = 3x + 3 implies that y cannot be 0, so this system cannot have a solution with a y-value of 0.
(D) 2x + 3y = 0
2x + 3(0) = 0
2x = 0
x = 0
x + 2y = -1
0 + 2y = -1
y = -1/2
The solution to system D does not have a y-value of 0.
Therefore, the solution to system A has a y-value of 0.
