Cheyenne is going to the store with $20.she wants buy as many bags of takis as she can. if takis are $1.50 per bag, what is the maximum number she can buy?
Cheyenne can buy a maximum of 13 bags of Takis.
We have,
To find the maximum number of bags of Takis Cheyenne can buy with $20, we need to divide the total amount of money she has by the cost per bag of Takis.
Cost per bag of Takis = $1.50
Total money Cheyenne has = $20
Maximum number of bags of Takis = Total money / Cost per bag
Maximum number of bags of Takis = $20 / $1.50
Maximum number of bags of Takis = 13.33
Since Cheyenne cannot buy a fraction of a bag, the maximum number of bags of Takis she can buy is 13.
Thus,
Cheyenne can buy a maximum of 13 bags of Takis.

suppose that there are seven committees with each pair of committees having a common member and each person being on two committees. how many people are there?
Minimum number of meeting required is 5 meetings required
As mentioned, if there is an edge between two committees, both the committee has atleast one member in common.
So if we consider two committees with atleast one member in common, i.e. we select two different vertices with an edge in between, the common member(s) in the committee can discuss and exchange ideas between the committees and thus they don't require a meeting to be scheduled.
So looking at the graph we can say that we only need to schedule meetings between committee with no edge connecting them.
6C2 - |E| or 15 - 10
= 5 meetings
What is the role of the committees?Committees keep an eye on ongoing government activities, spot problems that warrant legislative scrutiny, collect and assess data, and suggest courses of action to the Senate.

Solving the equation s = zr - 6zc^4 for z would give you: [tex]z = \frac{s}{r - 6c^4}[/tex].
How to Solve an Equation?Given the equation, s = zr - 6zc^4, to solve the equation for z, follow the steps below:
We have to isolate the variable "z" to one side of the equation if we are to solve the equation for z.
s = zr - 6zc^4
Factor out variable z
s = z(r - 6c^4)
Divide both sides of the equation by (r - 6c^4)
s/(r - 6c^4) = z(r - 6c^4) / (r - 6c^4)
s/(r - 6c^4) = z
[tex]z = \frac{s}{r - 6c^4}[/tex]
Therefore, solving the equation s = zr - 6zc^4 for z would give you: [tex]z = \frac{s}{r - 6c^4}[/tex].

logp(5) = x, logp(7) =y
Write logp([5p^2]/49) in terms of x and y
The expression is x+2-2y
It is given to us that logp5=x and logp7=y
Now we are required to find logp(5p^2)/49 in terms of x and y
we know that in logarithmic formulas
loga^b=b loga
logab = log a+log b
log a/b= log a- log b
Now using these formulas to find the solution,
logp 5p^2/49
= logp5+ logp p^2 -log 49
=logp5+2 logpp-2log7
we know that logpp=1,hence
= logp5+2 -2 logp7
=x+2-2y

Answer:
10.97 mm
Step-by-step explanation:
Hello!
First, let's construct an altitude, as shown in the picture below. An altitude is a height from one point to another side, forming a 90° angle at that intersection.
The length of the altitude is the same as the missing length, they are both parallel.
The length from the altitude to the slant line would be 6, as found by subtracting 8 from 14.
If you look closely, we can see a right triangle, and 12.5 mm is the hypotenuse. We know the measure for another side, and we can solve for the altitude using the Pythagorean Theorem: [tex]a^2 + b^2 = c^2[/tex], a and b are legs, and c is the hypotenuse.
In this case, 6 and the altitude are legs.
Solve for the Altitude[tex]a^2 + b^2 = c^2[/tex][tex]A^2 + 6^2 = 12.5^2[/tex][tex]A^2 + 36 = 156.25[/tex][tex]A^2 = 120.25[/tex][tex]A = \sqrt{120.25}[/tex][tex]A \approx 10.97[/tex]The altitude is around 10.97, so the missing length will also be 10.97 mm.

How to graph Linear Inequalities?A linear inequality is similar to a linear equation, but instead of a =, it will have an inequality sign like >,<, or ≤,≥.Place "y" on the left and the remaining variables on the right in the equation.Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>).Shade above the line in the graph for a "greater than" (y> or y≥)or below the line in the graph for a "less than" (y< or y≤).Given function: y > x + 4
Let's plot the graph of the given function and then match it with the options to see which is the solution.
So we will Plot y = x + 4 (as a dashed line because y > )
the coordinates will be,
x = 0 , y = 4
x = -1 , y = 3
x = -2 , y = 2
x = 1 , y = 5
x = 2 , y = 6

The height of the box is 12cm, having volume = 1200cm ³ .
What is the volume of triangular prism?A triangular prism's volume is the area that it takes up in all three dimensions. A prism is a solid object that has the same cross-section throughout its entire length, equal bases, and flat, rectangular side faces. Prisms can be divided into many categories and given different names depending on the form of their bases. A triangular prism has three rectangular lateral sides and two identical triangular bases.
The formula yields the volume of a triangular prism.
Volume of triangular prism = 1/2lwh
Where,
w = width
h = height
l = length.
We may determine the height by filling in the specified measurements.
1200cm ³ = 1/2 × (20 cm) × (10 cm) × h
h = (1200 cm³) / (100 cm²))
h = 12 cm

When some software companies develop software, they do it with "planned obsolescence"
in mind. This means that they plan on the sale of the software to rise, hit a point of
maximum sales, then drop and eventually stop when they release a newer version of the
software. Suppose a graph of the curve showing the number of sales over time can be
modeled with a parabola and that the company plans on the "life span" of its product to be
6 months, with maximum sales reaching 1.5 million units. Write an equation that models
this situation.
The equation of the parabola that models the given situation is y = [tex]\frac{-1}{6}(x-3)^{2}[/tex] + 1.5.
Define parabola and its types.A parabola is a roughly U-shaped mirror-symmetrical plane curve. It corresponds to a number of seemingly unrelated mathematical descriptions that all define the same curves.
To represent a parabola algebraically in the coordinate plane, the standard equation of a parabola is used. The general equation of the parabola is given by y = [tex]a(x-h)^{2}[/tex]+ k or x = [tex]a(y-k)^2[/tex] +h, where (h,k) denotes the vertex. A regular parabola's standard equation is [tex]y^2[/tex] = 4ax.
Now, the equation of parabola for the given situation is calculated as:
y = [tex]a(x-3)^2[/tex]+ 1.5
Now, put the value of x = 0 and y = 0.
0 = [tex]a(0-3)^2[/tex]+ 1.5
0 = 9a + 1.5
-9a = 1.5
a = - 1.5/9
a = -1/6
Now, put the value of a in equation y = [tex]a(x-3)^2[/tex]+ 1.5 to obtain:
y = [tex]\frac{-1}{6}(x-3)^{2}[/tex] + 1.5.

If m< EBC = 3y+10 and m< ABE = 2y-20, find m< EBF.
The value of angle m< EBF is determined as 56⁰.
What is the sum of angles in a straight line?
The sum of angles in a straight line is 180 degrees. The value of angle EBF can be determine using the concept of sum of angles in a straight line as shown below.
m< EBC + m< ABE = 180
3y + 10 + 2y - 20 = 180
5y - 10 = 180
5y = 180 + 10
5y = 190
y = 190/5
y = 38
The value of m< EBF is calculated as follows;
Assuming equal division, m< EBF = m< ABE
m< EBF = 2y - 20
m< EBF = 2(38) - 20
m< EBF = 56⁰
Thus, the value of angle m< EBF is determined as 56⁰.

David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes.
The unit rate in minutes per meter is 28.8 minutes per meter when David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes
The given Depth of the aquarium = 3/8 meters
Time taken to fill the aquarium = 3 3/5 minutes
To find the the unit rate in minutes per meter, we need to divide the time taken to fill the aquarium by the depth of the aquarium
So, Unit rate in minutes per meter = 3 3/5minutes ÷ 3/8 meters
= 18/5 ÷ 3/8
= 18/5 ×8/3
= 144/15
= 28.8 minutes per meter
Hence, the unit rate in minutes per meter is 28.8 minutes per meter when David fills an aquarium to a depth of 3/8 meters in 3 3/5 minutes

find the distance of a speed of 15m/s for 5 minutes
15m/s * 1km/1000m*60s/1 min*60 min/1hr=
You do the calculation.
Here are the conversions used in the conversion.
1km = 1000 m, 60 seconds = 1 minute, 60 minutes = 1 hour.
When you set up the problem the 15 meters is in the numerator and 1 second is in the denominator. To convert the 15 meters to km the next conversion factor needs to have 1km in the numerator and 1000 meters in the denominator. Now the 15 m will be divided by 1000 m which cancels the meters and leaves km.
The seconds in 15 m/s is in the denominator so to convert seconds to hours multiply by 60 seconds placing it in the numerator over 1 minutes. Use the same idea to set up the conversion from minutes to hours.
Practice this conversion. It is a fundamental conversion that any middle school student should know how to do.
