4.5x<=50-10
4.5x<=40
x<=8.9
round down because can't go beyond 50
x=8 max
Answer:
8 cups
Step-by-step explanation:
The equation is:
Let [tex]c[/tex] be amount of cups she can buy.
[tex]10+4.5c=50[/tex]
Using this equation, we get:
[tex]10+4.5c=50[/tex]
Subtract 10 from both sides
[tex]4.5c=40[/tex]
Divide both sides by 4.5
[tex]c[/tex] ≈ [tex]8.89[/tex]
Since she can only buy whole cups, the max she can buy is 8 cups.

If h(x) is the interse of f(x), what is the value of h(f(x))?
O 0
0 1
f(x)
Answer:
Step-by-step explanation:
Your options for solutions are nonsensical. We'll go about this a different way...namely, I'll tell you about a function and its inverse and then you can pick the answer from your options, as best as it will fit.
If f(x) = x + 1 and f(x) is the same thing as y, you can say that y = x + 1
If h(x) is the inverse of f(x), we have to find what h(x) is. The way to do that is to switch the x and y coordinates in f(x) and solve for the new y.
f(x) = y = x + 1 then x = y + 1 and y = x - 1.
That tells us the inverse of f(x), aka h(x). If we then take the composition of f(x) into h(x) we will find its value.
h(f(x)) ---> h(x + 1) = (x + 1) - 1 and
h(f(x)) = x
This will ALWAYS BE TRUE, NO MATTER WHAT FUNCTION YOU PLUG IN.
Fact: the composition of an inverse into its function = x
Fact: the composition of a function into its inverse = x

WILL MARK AS BRAINLIST What is the equation of the line written in general form? -x + y - 2 = 0 x + y - 2 = 0 2x + y - 2 = 0
Answer:
x4
Step-by-step explanation:
going down on the x axis
Answer:
0 = x+y -2
Step-by-step explanation:
The general form of a line is 0 = Ax + By + C where A is a positive integer
First write it in slope intercept form
y = mx+b where m is the slope and b is the y intercept
The slope is
m = (y2-y1)/(x2-x1) (2,0) and (0,2)
= (2-0)/(0-2)
= 2/-2
= -1
and the y intercept is 2
y = -1x +2
Subtract y from each side
0 = -x -y +2
Multiply by -1
0 = x+y -2
Q3: Determine the difference 34.7 – (–8.6). Determine la diferencia para 34.7 - (–8.6).

Since there are two negative signs, it cancels out, and becomes an adding sign or a positive.
Thus, it is now, 34.7 + 8.6
Solve:
34.7 + 8.6 = 43.3
Therefore, the difference of 34.7 - (-8.6) is 43.3
Betty sets up a lemonade stand and charges $1 per glass. It cost her $50 to set up the stand. Which function gives the profit, p, she makes by selling g glasses of lemonade? The number of glasses of lemonade, g, that Betty needs to sell to make a profit, p, if the setup cost her $50 is given by the function p(g) = .
Answer:
p = g - 50
Step-by-step explanation:
profit = income - expenses
income = 1 * g = g
expenses = $50
p = g - 50
If g = 50, then
p = 50 - 50 = 0
If she sells 50 glasses of lemonade, she breaks even. That means she makes no profit, but also she loses nothing.
If she sells more than 50 glasses, then she makes a profit.
Answer:
50 is the answer

Square OABC is drawn on a centimetre grid. O is (0,0) A is (2,0) B is (2,2) C is (0,2) Write down how many invariant points there are on the perimeter of the square when OABC is rotated 90 degrees clockwise, centre (2,0).
Answer:
There is one point: A (x, y) = (2, 0)
Step-by-step explanation:
A point of the square OABC is invariant only if its location coincides with location of the rotation axis, that is, that such point experiments only rotation, no translation in any form. The center of rotation coincides with the location of one of the vertices of the square and, therefore, there is one invariant point on the perimeter: A (x, y) = (2, 0)
A company laid off one-sixth of its workforce because of falling sales. If the number of employees after the layoff is 690, how many employees were laid off?
Answer:
138
Step-by-step explanation:
Let the number of employees before the layoff be x.
1/6 of the company's workers were laid off and the remaining workers are 690. This means that:
1/6 * x = x - 690
=> x/6 = x - 690
=> 690 = x - x/6
690 = 5x/6
=> x = (690 * 6) / 5
x = 828
There were 828 workers before the layoff. Therefore, the number of employees that were laid off is:
828 - 690 = 138 employees
The company's laying off its workforce is an illustration of proportions.
A total of 138 employees were laid off
The proportion (p) laid off is given as:
[tex]p = \frac 16[/tex]
The proportion (q) remaining in the workforce would be
[tex]q = 1 - p[/tex]
This gives
[tex]q = 1 - \frac 16[/tex]
[tex]q =\frac 56[/tex]
The workforce after 1/6 were laid off is given as 690.
So, we have:
[tex]q \times n = 690[/tex]
Where n represents the original workforce
This gives
[tex]\frac 56 \times n = 690[/tex]
Multiply both sides by 6/5
[tex]n = 828[/tex]
The number of employees that were laid off is:
[tex]Employee = 828 - 690[/tex]
[tex]Employee = 138[/tex]
Hence, 138 employees were laid off

Calculate the mean and standard deviation of the data set ...
Answer:
Mean: 12.9
Standard deviation: 14.8
Step-by-step explanation:
The mean is calculated adding all of the values and dividing by the number of elements:
[tex]m=\frac{2+3+7+12+1+4+27+49+11}{9}=\frac{116}{9}=12.9[/tex]
to find the standard deviation, we first find the variance (which is defined as the sum of all the elements subtracting the mean and squared and then dividing by the total amount of elements):
[tex]v=\frac{(2-12.9)^2+(3-12.9)^2+(7-12.9)^2+(12-12.9)^2+(1-12.9)^2+(4-12.9)^2+(27-12.9)^2+(49-12.9)^2+(11-12.9)^2}{9}\\[/tex]
[tex]v=\frac{1978.89}{9}\\[/tex]
[tex]v=219.88[/tex]
Noe that we have the variance, we can calculate the standard deviation.
The stardard deviation is defined as the squared root of the variance:
[tex]standardDeviation=\sqrt{v}[/tex]
we substitute the variance:
[tex]standardDeviation=\sqrt{219.88} \\standardDeviation=14.8[/tex]
Thus, the answer is:
Mean: 12.9
Standard deviation: 14.8

Answer:
A =576 pi in ^2
Step-by-step explanation:
Circumference is given by
C = 2 * pi *r
48 pi = 2 * pi *r
divide by 2 pi
48 pi /2 pi = 2 * pi * r / 2 pi
24 = r
We can find the area by
A = pi r^2
A = pi (24)^2
A =576 pi in ^2
Answer:
576π in^2
Step-by-step explanation:
Circumference of circle (C) = 2πr = 48π in
2πr = 48 π
r = 48π/2π = 24 in
Area of circle (A) = πr^2
r (radius of circle) = 24 in
A = π(24 in)^2 = 576π in^2

The length of the third side is 32 - 8 - 11 = 13. s (which is half of the perimeter) is 32 / 2 = 16 so the answer is:
√s(s-a)(s-b)(s-c) = √16 * (16 - 8) * (16 - 11) * (16 - 13) = √16 * 8 * 5 * 3 = √1920 = 8√30
Triangle R T S is sitting on a horizontal line. Line S R extends through point Q to form exterior angle T R Q. Angle R T S is (25 x) degrees. Angle T S R is (57 + x) degrees. Exterior angle T R Q is (45 x) degrees.
Answer:
x = 3
Question: Find the value of x.
Step-by-step explanation:
Given:
- Triangle R T S is sitting on a horizontal line
- Line S R extends through point Q to form exterior angle T R Q
- m∠RTS is (25 x)°, m∠TSR is (57 + x)° , m∠TRQ is (45 x)°
Lets find the value of x
∠TRQ is an exterior angle of Δ RTS at the vertex R
The opposite interior angles to vertex R are ∠RTS and ∠TSR
∴ m∠TRQ = m∠RTS + m∠TSR
m∠TRQ = (45 x)°
m∠RTS = (25 x)°
m∠TSR = (57 + x)°
Substitute these measures in the equation above
45 x = 25 x + 57 + x
45 x = 26 x + 57
19 x = 57
x = 3

DG.
6 units
12 units
18 units
24 units
Answer:
(C)18 units
Step-by-step explanation:
Point G is the centroid of triangle ABC.C is a vertex of the triangleD is the midpoint of the side opposite the vertex.From Centroid Theorems, we know that the distance from the centroid to the vertex is twice as long as the distance from the centroid to the midpoint of the side opposite the vertex.
Therefore:
CG=2DG
Let the length of segment DG =x
The length of segment CG is 6 units greater, therefore: CG=x+6
Substituting into CG=2DG:
x+6=2x
2x-x=6
x=6 Units
Therefore:
CD=CG+GD
=6+6+6
=18 Units
The correct option is C.
Answer:
18
Step-by-step explanation:
Line segment CG is amount to 12 and line segment GD is 6. The length of the whole line segment, CD is 18 by adding 12 and 6.
