parallelogram?
A 33.5 square inches
B 54.5 square inches
C 64.5 square inches
D 32.25 square inches
Answer:
C= 64.5 square inches :)
Step-by-step explanation:
To find the area of a parallelogram you have to use this formula:
A= bh b=base h=height

Which equation could be used to find the circumference, in inches, of a garbage can if the radius of its circular basis is 10 inches?
Answer: A
The circumference formula for a circle is 2 x pi x r. So if the radius is 10 then 2 x 10 = 20. Then 20 x pi.
Hope it helps.
The circumference of the garbage can will be 20 x π inches
What is the circumference of a circle?The circumference of a circle or oval in geometry is its perimeter. That is, if somehow the circle were expanded out and squared out to a line segment, the perimeter would be the lengths of the arc. The curve distance around any closed image is more often referred to as the circumference.
Let 'r' be the radius of the circle that is 10 inched.
The circumference of the circle will be
C = 2πr units
The radius of the garbage can is 10 inches. Then the circumference of the garbage can is calculated as,
C = 2πr
C = 2 x πx 10
C = 20 x π inches
The circumference will be 20 x π inches.

Hydrocodone bitartrate is used as a cough suppressant. After the drug is fully absorbed, the quantity of drug in the body decreases at a rate proportional to the amount left in the body, with constant of proportionality k. Suppose that the half-life of hydrocodone bitartrate in the body is 3.9 hours, and that the oral dose taken is 9 mg.
a) Write a differential equation for the quantity Q of hydrocodone bitartrate in the body at time t, in hours, since the drug was fully absorbed.
b) Solve your differential equation, assuming that at the patient has just absorbed the full 9 mg dose of the drug.
c) Use the half-life to find the constant of proportionality k.
d) How much of the 9 mg dose is still in the body after 12 hours?
Answer:
a. dQ/dt = -kQ
b. [tex]Q = 9e^{-kt}[/tex]
c. k = 0.178
d. Q = 1.063 mg
Step-by-step explanation:
a) Write a differential equation for the quantity Q of hydrocodone bitartrate in the body at time t, in hours, since the drug was fully absorbed.
Let Q be the quantity of drug left in the body.
Since the rate of decrease of the quantity of drug -dQ/dt is directly proportional to the quantity of drug left, Q then
-dQ/dt ∝ Q
-dQ/dt = kQ
dQ/dt = -kQ
This is the required differential equation.
b) Solve your differential equation, assuming that at the patient has just absorbed the full 9 mg dose of the drug.
with t = 0, Q(0) = 9 mg
dQ/dt = -kQ
separating the variables, we have
dQ/Q = -kdt
Integrating we have
∫dQ/Q = ∫-kdt
㏑Q = -kt + c
[tex]Q = e^{-kt + c}\\Q = e^{-kt}e^{c}\\Q = Ae^{-kt} (A = e^{c})[/tex]
when t = 0, Q = 9
[tex]Q = Ae^{-kt} \\9 = Ae^{-k0}\\9 = Ae^{0}\\9 = A\\A = 9[/tex]
So, [tex]Q = 9e^{-kt}[/tex]
c) Use the half-life to find the constant of proportionality k.
At half-life, Q = 9/2 = 4.5 mg and t = 3.9 hours
So,
[tex]Q = 9e^{-kt}\\4.5 = 9e^{-kX3.9}\\\frac{4.5}{9} = e^{-kX3.9}\\\frac{1}{2} = e^{-3.9k}\\[/tex]
taking natural logarithm of both sides, we have
[tex]ln\frac{1}{2} = ln(e^{-3.9k})\\\\-ln2 = -3.9k\\k = -ln2/-3,9 \\k = -0.693/-3.9\\k = 0.178[/tex]
d) How much of the 9 mg dose is still in the body after 12 hours?
Since k = 0.178,
[tex]Q = 9e^{-0.178t}[/tex]
when t = 12 hours,
[tex]Q = 9e^{-0.178t}\\Q = 9e^{-0.178X12}\\Q = 9e^{-2.136}\\Q = 9 X 0.1181\\Q = 1.063 mg[/tex]

A grocery store offers a cheese sampler that includes a pepper cheddar cheese that costs $17 per kilogram and Pennsylvania Jack that costs $8 per kilogram. How many kilograms of each were used to make a 6-kilogram mixture that costs $10.25 per kilogram? pepper cheddar kg Pennsylvania Jack kg
Answer:
The quantity of pepper cheddar cheese required = 2.5 kilograms
The quantity of Pennsylvania Jack required = 4.5 kilograms
Step-by-step explanation:
Let x = Quantity of pepper cheddar cheese
y= Quantity of Pennsylvania Jack
As per given , we have the following system of equations:
Multiply 8 to equation(1) , we get
Eliminate (3) from (2) , we get
Put value of x in (1) , we get
Hence, the quantity of pepper cheddar cheese required = 2.5 kilograms
The quantity of Pennsylvania Jack required = 4.5 kilograms
Multiply me by 4. Then subtract 29 and you get 23. What is my number?
Answer:

Step-by-step explanation:
13 x 4 = 52 - 29 = 23
Nina needs to make an array to solve this division problem: 142 3. How should she do it?
She should make rows of 3 until she has 140 rows. She will have 1 left over.
She should make rows of 3 until she has 142 rows. She will have o left over.
She should make rows of 3 until she has 47 rows. She will have 0 left over.
She should make rows of 3 until she has 47 rows. She will have 1 left over.
Answer: D
Step-by-step explanation: She should make rows of 3 until she has 47 rows. She will have 1 left over. Because 47*3 = 141 plus the left over 142
Which of the following BEST describes a TREE?
a) A complete graph, with exactly 4 vertices.
b) A connected graph, each vertex has a degree of 2 or greater.
c) A connected graph with at least 3 cycles.
d) A connected graph with no cycles.
Answer:
Step-by-step explanation:
We first start understanding what is a tree:
A tree can be understood as a graph such that two nodes ( or vertices ) are connected by at most one path.
So the best definition that fit the above one is d. Note that
In a complete graph we have multiple paths to connected two nodes. So that a is false. Similarly, b is false. If we have cycles in a graph, that implies more than two paths to connected two nodes. So c is false.
A connected graph with no cycles is used to describe a TREE so option (D) will be correct.
What is a graph?A graph is a diametrical representation of any function between the dependent and independent variables.
The graph is easy to understand the behavior of the graph.
For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.
A TREE diagram is a graph where any two nodes or more are connected at one node by another segment while another remains open.
Since the TREE diagram is become by the disconnected node at one end it means it is not going to form any cycle.
Hence "A connected graph with no cycles is used to describe a TREE".
