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.

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%

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.
Hence , it is a translation of 5 units down and a vertical stretch of 100.

The difference of a number and 4/3 is 11/3. What is the number?
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

Triangle UVW is drawn with vertices at U(−1, 1), V(0, −4), W(−4, −1). Determine the coordinates of the vertices for the image, triangle U′V′W′, if the preimage is rotated 90° clockwise.

U′(1, 1), V′(−4, 0), W′(−1, 4)

The coordinates of the vertices for the image of the triangle U′V′W′ is
U′(1, 1), V′(−4, 0), W′(−1, 4)
How to find the coordinates after transformationTo rotate a point 90 ° clockwise about the origin, we can apply the transformation (x, y) → (y, -x)
So applying this transformation to each vertex of triangle UVW we get
U(−1, 1) → U' = (1, 1)
V(0, −4) → V' = ( -4, 0)
W(−4, −1) → W' = (-1, 4)

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

Which statement about the following equations is correct?
y = 2x + 5
y
O The equations are independent because the lines intersect in one point.
The equations are dependent because the lines are the same line.
O The equations are independent because the equations represent parallel lines.
O The equations are dependent because the lines do not intersect.
= -2x+5
Answer:
Step-by-step explanation:
The correct statement about the given equations is: "The equations are dependent because the lines are the same line."
In the equation y = 2x + 5, the slope is 2, which means the line has a positive slope and is upward sloping.
The y-intercept is 5, indicating that the line intersects the y-axis at the point (0, 5).
The equation y = -2x + 5 is equivalent to y = 2(-x) + 5, which has the same form as the first equation but with a negative slope.
However, the equations are still dependent because when you simplify the second equation, you obtain the first equation.
These two equations represent the same line with a different slope. Therefore, they are dependent, and any point that satisfies one equation will satisfy the other equation as well.

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.
