Kristin and deshawn are selling flower bulbs for a school fundraiser customers can buy bags of windflower bulbs and packages of crocus bulbs Kristen sold 4 bags of windflower bulbs and 9 packages of crocus for a total of 200 deshawn sold 2 bags of windflower bulbs and 6 packages of crocus bulbs for a total of 124 find the cost each of one of the bag of windflower bulbs and one package of crocus bulbs ?
Answers
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
Therefore, each one bag of windflower bulbs and one package of crocus bulbs is $14 and $16 respectively.

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 )
Answers
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.

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
Answers
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 ...

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(2)(4) = 4π
The area of a triangle with the same semi-axes is ...

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

Area of small sector =
cm2
Area of large sector =
cm2
Answers
To find the area of the large sector, we need to subtract the area of triangle ADB from the area of the circle sector ACB. We can use the Law of Cosines to find the length of segment AD:
AD^2 = AB^2 + BD^2 - 2 * AB * BD * cos(ACB)
AD^2 = 3^2 + 2^2 - 2 * 3 * 2 * cos(131)
AD^2 = 13 - 12cos(131)
AD = sqrt(13 - 12cos(131))
The area of triangle ADB is (1/2) * AB * AD * sin(DAB) = (1/2) * 3 * sqrt(13 - 12cos(131)) * sin(49) = 1.786 cm^2 (rounded to 3 decimal places).
The area of the large sector is pi * 3^2 - 1.786 = 23.556 cm^2 (rounded to 3 decimal places).
Therefore, the area of the small sector is 3.422 cm^2 and the area of the large sector is 23.556 cm^2.
An economy's consumer price index (CPI) is described by the function f(t)=-0.1t^3+3t^2+500 where t=0 corresponds to the year 1995. Find the point of inflection of the function.
Answers
Explanation: the point of inflection refers to when a function switches concavity (i.e. up or down). If the second derivative of f is positive, the graph is concave up, and if it is negative, the graph is concave down. This means that the graph switches concavity when the second derivative equals zero.
To find the second derivative (f’’(t)), we shall first find f’(t), or the first derivative. Because each term is separated by addition/subtraction, we can take the derivative of each term separately. Using the power rule, ((d/dx)(-0.1t^3)) = -0.1(3)(t)^(3-1)= -0.3t^2. For d/dx of 3t^2, use the power rule again: 3(2)t^(2-1) = 6t. The derivative of 500 is 0 because it is a constant. f’(t) = -0.3t^2 + 6t.
Now we shall do this process again to find the second derivative. For the first term, d/dx of -0.3t^2 = -0.3(2)t^(2-1) = -0.6t. For 6t, d/dx equals 6(1)t^(1-1) = 6. f”(t) = -0.6t + 6
Now that we have the second derivative, we set it equal to zero and solve for t. 0 = -0.6t + 6, -6 = -0.6t, t = 10. Because t = 10 years, the point of inflection occurs in 1995 + 10 = 2005.

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?
Answers
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
Therefore, the family's monthly payment should be $504.70.

What is the area of DEF? D to F is 7.65, d to e is 2.12 and e to f is 6
Answers
A = sqrt(s(s-a)(s-b)(s-c))
where s is the semiperimeter of the triangle, defined as:
s = (a + b + c)/2
In this case, we have:
a = DE = 2.12
b = EF = 6
c = DF = 7.65
The semiperimeter is:
s = (a + b + c)/2 = (2.12 + 6 + 7.65)/2 = 7.885
Therefore, the area of triangle DEF is:
A = sqrt(s(s-a)(s-b)(s-c)) = sqrt(7.885(7.885-2.12)(7.885-6)(7.885-7.65)) = 9.63

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?
Answers
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%

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)
Answers
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

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
