Una maestra esta comprando lapices para su salon de clases. Si una docena de lapices cuesta $0.79 puede comprar lapices con $5?
Answer:
Cantidad total de lapices= 76
Step-by-step explanation:
Dada la siguiente información:
Costo por docena= $0.79
Presupuesto total= $5
Para calcular la cantidad total de lapiceras que se pueden comprar con $5, debemos usar la siguiente formula:
Cantidad total de lapices= presupuesto total / costo por docena
Cantidad total de lapices= 5 / 0.79
Cantidad total de lapices= 6.33
Para ser mas exactos:
0.33*12= 4
Cantidad total de lapices= 6*12 + 4
Cantidad total de lapices= 76

For the arithmetic sequence beginning with the terms {-2, 0, 2, 4, 6, 8...}, what is the sum of the first 18 terms?
Answer:
The sum of the first 18 terms is 270.
Step-by-step explanation:
First the 18th term is calculated which is gotten using the following steps below:
an = a1 + d ( n - 1 )
Where, an =18th term
a1= first term (-2)
d = difference
n = 18
Therefore, 18th term
an= -2 + 2 (18 - 1)
= -2 + 2 (17)
= -2 + 34
18th term = 32
To calculate the sum of the first 18th terms the following steps are used,
Sn = n(a1 + an)/2
Where,
Sn = sum of 18th term
n = 18
a1 = -2
an = 18 term
Therefore,
Sn = 18 (- 2+ 32)/2
= 18 (30)/2
= 18 ×30 /2
= 540/2
= 270
y = 3x - 1
3x - y = 9
X=
A) x = 123, y = 4 4
B) x=3, y = 0
C) No solution
D) Infinitely many solutions
Answer:
no solution.
Step-by-step explanation:
given that, y = 3x-1
so,
in equation, 3x-y = 9
putting the value of y here,
3x-(3x-1) = 9
3x-3x+1 = 9
3x and 3x is cancelled.
hence, no solution

How does the range of g(x)=6/x compare with the range of the parent function f(x)=1/x?
Answer:
The range of both [tex]f(x)[/tex] and [tex]g(x)[/tex] is all nonzero real numbers.
Step-by-step explanation:
The range of the function is the set of real number for [tex]y[/tex]. The rational function of the form [tex]y = \frac{a}{x}[/tex], where [tex]a[/tex] is a constant, has a range represented by the subset of nonzero real numbers. This is: [tex]Ran\{f(x)\} = \mathbb{R}-\{0\}[/tex]
Hence, the correct answer is: The range of both [tex]f(x)[/tex] and [tex]g(x)[/tex] is all nonzero real numbers.

A horizontal line passes through the point (5, –1). Which point is also on this line?
(0, 0)
(–1, 5)
(5, –4)
(–2, –1)
Answer:
Step-by-step explanation:
A horizontal line is a "y = " line. So the horizontal line that goes through the point given has the equation y = -1 (-1 being the y coordinate of the point). That means that another point on this line, y = -1, will also have to have a y coordinate of -1. The only one is the last one, (-2, -1).

what is the value of x? 0 = x/6 - 3
Answer:
18 = x
Step-by-step explanation:
0 = x/6 - 3
Add 3 to each side
0+3 = x/6-3+3
3 = x/6
Multiply by 6 on each side
3*6 = x/6*6
18 = x

Angle B = ?
Need help.
Answer:
angle B = 33.42
Step-by-step explanation:
take angle B as reference angle
using tan rule
tan B = opposite/adjacent
tan B = 6/9
tan B = 0.66
B = [tex]tan^{-1} (0.66)[/tex]
B = 33.424
B = 33.42
Mixing 4 ml of red paint and 15 ml of yellow paint makes orange paint. How much red would be needed if you use 1500 ml of yellow paint?
Answer:
Amount of red paint needed for 1500 ml yellow paint = 400 ml
Step-by-step explanation:
Given:
ration of red paint to yellow paint = 4 ml to 15 ml
Find:
Amount of red paint needed for 1500 ml yellow paint
Computation:
Amount of red paint needed for 1500 ml yellow paint = [ration of red paint to yellow paint]1500
Amount of red paint needed for 1500 ml yellow paint = [4/15]1500
Amount of red paint needed for 1500 ml yellow paint = [4]100
Amount of red paint needed for 1500 ml yellow paint = 400 ml

Vertex of a quadratic function:
Suppose we have a quadratic function in the following format:
[tex]f(x) = ax^{2} + bx + c[/tex]
It's vertex is the point [tex](x_{v}, y_{v})[/tex]
In which
[tex]x_{v} = -\frac{b}{2a}[/tex]
[tex]y_{v} = -\frac{\Delta}{4a}[/tex]
Where
[tex]\Delta = b^2-4ac[/tex]
If a<0, the vertex is a maximum point, that is, the maximum value happens at [tex]x_{v}[/tex], and it's value is [tex]y_{v}[/tex].
Turning point of a quadratic function:
The turning point of a quadratic function is the vertex.
y = x2 — 6x + 8
This means that [tex]a = 1, b = -6, c = 8[/tex]
Now, we find the vertex.
[tex]x_{v} = -\frac{b}{2a} = -\frac{-6}{2(1)} = 3[/tex]
[tex]\Delta = b^2-4ac = (-6)^2-4(1)(8) = 36 - 32 = 4[/tex]
[tex]y_{v} = -\frac{4}{4(-1)} = -1[/tex]

Answer:
(2,7)
Step-by-step explanation:
It's funny, this is the exact topic I just learned.
Ok, 2,-7 would be in the fourth quadrant (IV).
So using this information if we want to reflect it over the x axis, the point would just got over the x axis in quadrant 1. We know that quadrant 1 is (++) so the ordered pair MUST be positive. Hence the answer of (2,7)

Here is the complete question :
there are 13 apples in a basket 4 of these apples are green the rest of them are red
What what is the ratio of red apples to all the apples in the basket
Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
ratio of red apples to all the apples in the basket = Number of red apples : total number of apples
Number of red apples = total number of apples - number of green apples
13 - 4 = 9

A circle has a center at (-2, 5) and a radius of bold 3 square root of bold 2units. What is the equation of the circle in standard form?
Given:
The center of the circle = (-2,5)
The radius of the circle = [tex]3\sqrt{2}[/tex] units.
To find:
The equation of the circle is standard form.
Solution:
The standard form of a circle is:
[tex](x-h)^2+(y-k)^2=r^2[/tex] ...(i)
Where, (h,k) is the center of the circle and r is the radius of the circle.
It is given that the center of the circle is (-2,5). So, [tex]h=-2,\ k=5[/tex].
The radius of the circle is [tex]3\sqrt{2}[/tex] units. So, [tex]r=3\sqrt{2}[/tex].
Putting [tex]h=-2,\ k=5[/tex] and [tex]r=3\sqrt{2}[/tex] in (i), we get
[tex](x-(-2))^2+(y-(5))^2=(3\sqrt{2})^2[/tex]
[tex](x+2)^2+(y-5)^2=18[/tex]
Therefore, the equation of the circle is [tex](x+2)^2+(y-5)^2=18[/tex].
