Dr. Salaam orders 39 grams of marijuana for a patient. Each bud is about 0.07 grams of marijuana.
How many buds will each patient need and If the dispensary charges $530 an ounce for the strain the patient likes, how much will the patient have to pay in total? (28.4 grams = 1 ounce)
The patient will have to pay approximately $727.74 in total.
How to solve for the dispensary chargesTotal grams of marijuana: 39 grams
Weight of each bud: 0.07 grams
Number of buds = Total grams of marijuana / Weight of each bud
Number of buds = 39 / 0.07 ≈ 557.14
Since the patient can't purchase a fraction of a bud, they will need 558 buds (rounding up).
Now, let's calculate the total cost.
Dispensary cost: $530 per ounce (28.4 grams)
First, we need to find the cost per gram:
Cost per gram = $530 / 28.4 ≈ $18.66
Total grams of marijuana: 39 grams
Total cost = Cost per gram * Total grams of marijuana
Total cost = $18.66 * 39 ≈ $727.74
The patient will have to pay approximately $727.74 in total.

Select the correct answer. What is 12% of 50? A. 6 B. 7 C. 10 D. 12
Answer:
A. 6
Step-by-step explanation:
We know that 12% can be written in fraction form as [tex]\frac{12}{100}[/tex]. So, 12% of 100 is [tex]100\cdot\frac{12}{100} = 12[/tex].
We also know that 50 is half of 100. Therefore, 12% of 50 is exactly half of 12% of 100:
[tex]12\% \cdot 50[/tex]
[tex]= \frac{1}{2}(12\% \cdot 100)[/tex]

Martin has 1/4 of a bag of chocolate chip cookies. The bag weighs 4 pounds. How
many pounds of cookies does he have?
Answer:
1 pound----------------------
Martin has 1/4 of a bag of chocolate chip cookies.
Since the bag weights 4 pounds, Martin has:
1/4 × 4 pounds = 1 pound of chocolate chip cookiescan we express 1,012 as the sum of two consecutive number?
Answer:
Step-by-step explanation:
Let's check if we can express it or not ;
Let the two consecutive number be x and x + 1 .
x + x + 1 = 1012
2x + 1 = 1012
2x = 1011
x = 505.5
Then two consecutive numbers are 505.5 and 506.5
It isn't said that number should be integer ? It can be anything . That is why " yes " would be the correct answer .

2. The base of a solid is a region bounded by the curve x^2/8^2+y^2/4^2=1(an ellipse with the major and minor axes of lengths 16 and 8 respectively). Find the volume of the solid if every cross section by a plane perpendicular to the major axis (x-axis) has the shape of an isosceles triangle with height equal to 1/4 the length of the base
Answer:
85 1/3 cubic units
Step-by-step explanation:
You want the volume of a solid whose base is the ellipse in the x-y plane with axes 16 and 8 units and whose cross sections perpendicular to the major axis are isosceles triangles with height equal to 1/4 of the cross section dimension parallel to the minor axis.
AreaThe isosceles triangle cross section has base 2y and height (2y)/4, so area of ...
A = 1/2bh
A = (1/2)(2y)(2y/4) = y²/2
VolumeA differential of volume is the product of the area of a slice and its thickness:
dV = A·dx = (1/2)y²·dx
The total volume is the integral of this differential of volume over the interval x ∈ [-8, 8]. That integral will be twice the integral on the interval [0, 8}, so we have ...
[tex]\displaystyle V=2\int_0^8{\dfrac{y^2}{2}}\,dx=16\int_0^8{\left(1-\dfrac{x^2}{64}\right)}\,dx=16\left((8-0)-\dfrac{8^3-0^3}{3\cdot64}\right)\\\\\boxed{V=85\dfrac{1}{3}\text{ cubic units}}[/tex]
__
Alternate computation
The volume of half an ellipsoid with semi-axes 2, 4, and 8 is ...
V = (1/2)(4/3)π(abc)
V = (1/2)(4/3)π(2)(4)(8) = 128π/3
The area of half an ellipse with semi-axes 2 and 4 is ...
A = (1/2)π(ab)
A = (1/2)π(2)(4) = 4π
The area of a triangle with the same semi-axes is ...
A = 1/2bh = (1/2)(2)(2·4) = 8
Then the ratio of triangle area to ellipse area at each cross section is ...
triangle / ellipse = 8/(4π) = 2/π
The volume of the solid of interest is estimated to be this factor multiplied by the volume of the half-ellipsoid:
(2/π)(128π/3) = 256/3 = 85 1/3 . . . . same as above

If a family borrows 43,008 for an addition to their home and the loan is to be paid off in monthly payments over 9 years how much should each payment be?
The family's monthly payment should be $504.70.
To calculate the monthly payment for a loanWe can use the following formula:
[tex]P = (r * A) / (1 - (1 + r)^(-n))[/tex]
where
P = a recurring paymentr is the ongoing interest rate.A = loan amountn = total number of paymentsIn this instance, the total loan amount is $43,008, the total number of payments is 9 years * 12 months/year = 108 months . The yearly interest rate must first be divided by 12 to determine the monthly interest rate. Assume that there is a 5% yearly interest rate.
[tex]r = 0.05 / 12 = 0.00417[/tex]
Now we can substitute the values into the formula and solve for P:
[tex]P = (0.00417 * $43,008) / (1 - (1 + 0.00417)^(-108))[/tex]
= $504.70

Okay so this is for my portfolio. I have two figures; a rectangular prism (think cereal box) and a cylinder. Is it possible for the cylinder to have a larger VOLUME than the prism, but a smaller measurement of cubic inches?? (Please say yes )
Step-by-step explanation:
No, it is not possible. Cubic inches are a measurement of volume. If the cylinder has a larger volume, then it also has more cubic inches.
Answer:
no TWT
Step-by-step explanation:
Because these solids have the same height and the same cross-sectional areas at every level, the solids have the same volume due to Cavalieri's principle. The volume of the prism is: V = A B a s e ⋅ h = π r 2 h Therefore, the volume of the cylinder is: V = π r 2 h This should make sense because a cylinder is essentially a circular prism.

The function is transformed and it is a vertical stretch with a factor of 100 and a translation 5 units down
Given data ,
Let the transformed function be represented as f' ( x )
Now , The pace of filling a 100-gallon fish tank is x gallons per minute. The tank has been filling for five minutes already.
The parent function's graph is f (x) = x.
Consequently, the function's graph is provided as
f ( x ) = ( 100/x ) - 5
The graph is now 100 times longer vertically, giving us f (x) = 100/x.
By translating by 5 units down, we obtain f (x) = (100/x) - 5.

The cost each of one of the bag of windflower bulbs and one package of crocus bulbs is $14 and $16 respectively.
What is the cost of each of bag of windflower bulbs and a package of crocus bulbs?Let
cost each of one of the bag of windflower bulbs = x
Cost of each one package of crocus bulbs = y
4x + 9y = 200
2x + 6y = 124
Multiply (2) by 2
4x + 12y = 148
So,
4x + 9y = 200
4x + 12y = 248
Subtract to eliminate x
12y - 9y = 248 - 200
3y = 48
divide both sides by 3
y = 48/3
y = 16
Substitute y = 16 into (1)
4x + 9y = 200
4x + 9(16) = 200
4x + 144 = 200
4x = 200 - 144
4x = 56
x = 56/4
x = 14

In a class of 30 students, 12 have a cat and 19 have a dog. There are 6 students who
do not have a cat or a dog. What is the probability that a student chosen randomly
from the class has a dog?
Answer:
P(dog) = 12/30 = 0.4 or 40%
Step-by-step explanation:
We can use the formula for probability:
P(dog) = number of students with a dog / total number of students
To find the number of students with a dog, we can use the fact that 19 students have a dog and 6 students have neither a cat nor a dog:
number of students with a dog = total number of students - number of students with no pets - number of students with only a cat
number of students with a dog = 30 - 6 - 12 = 12
So the probability that a student chosen randomly from the class has a dog is:
P(dog) = 12/30 = 0.4 or 40%

How to obtain the reduced row echelon form?The reduced row echelon form of a matrix is matrix in which the matrix except the last column has the format of an identity matrix, that is, a matrix in which the principal diagonal elements are of 1 and the rest of the elements are of 0.
Hence we can use a mix of row operations, along with the solution of a system of equations, to obtain the reduced row echelon form of a matrix.
The matrix in the context of this problem is defined as follows:
[tex]\left[\begin{array}{cccc}-1&5&-3&6\\0&3&6&-42\\0&-6&-1&18\end{array}\right][/tex]
First we want a value of 1 at line 1, column 1, hence we multiply the first line by -1, that is:
R1 -> -R1.
Hence:
[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&3&6&-42\\0&-6&-1&18\end{array}\right][/tex]
Then we want a value of 1 at line 2 column 2, thus:
R2 -> R2/3.
Hence:
[tex]\left[\begin{array}{cccc}1&-5&3&-6\\0&1&2&-14\\0&-6&-1&18\end{array}\right][/tex]

Answer:
n = 5
Step-by-step explanation:
Let n represent the unknown the numberSince we know the difference of n and 4/3 is 11/3, we can use the following equation to solve for n: n - 4/3 = 11/3Step 1: Multiply both sides by 3 (i.e., the least common multiple of 3) to clear the fractions:
3(n - 4/3 = 11/3)
3n -12/3 = 33/3
3n - 4 = 11
Step 2: Add 4 to both sides:
(3n - 4 = 11) + 4
3n = 15
Step 3: Divide both sides by 3 to solve for n:
(3n = 15) / 3
n = 5
