Answer:
Cost for each pound of jelly beans: $2.75
Cost for each pound of almonds: $3.75
Step-by-step explanation:
Let J be the cost of one pound of jelly beans.
Let A be the cost of one pound of almonds.
Using the given information, we can create a system of equations.
Given 3 pounds of jelly beans and 5 pounds of almonds cost $27:
[tex]\implies 3J + 5A = 27[/tex]
Given 9 pounds of jelly beans and 7 pounds of almonds cost $51:
[tex]\implies 9J + 7A = 51[/tex]
Therefore, the system of equations is:
[tex]\begin{cases}3J+5A=27\\9J+7A=51\end{cases}[/tex]
To solve the system of equations, multiply the first equation by 3 to create a third equation:
[tex]3J \cdot 3+5A \cdot 3=27 \cdot 3[/tex]
[tex]9J+15A=81[/tex]
Subtract the second equation from the third equation to eliminate the J term.
[tex]\begin{array}{crcrcl}&9J & + & 15A & = & 81\\\vphantom{\dfrac12}- & (9J & + & 7A & = & 51)\\\cline{2-6}\vphantom{\dfrac12} &&&8A&=&30\end{array}[/tex]
Solve the equation for A by dividing both sides by 8:
[tex]\dfrac{8A}{8}=\dfrac{30}{8}[/tex]
[tex]A=3.75[/tex]
Therefore, the cost of one pound of almonds is $3.75.
Now that we know the cost of one pound of almonds, we can substitute this value into one of the original equations to solve for J.
Using the first equation:
[tex]3J+5(3.75)=27[/tex]
[tex]3J+18.75=27[/tex]
[tex]3J+18.75-18/75=27-18.75[/tex]
[tex]3J=8.25[/tex]
[tex]\dfrac{3J}{3}=\dfrac{8.25}{3}[/tex]
[tex]J=2.75[/tex]
Therefore, the cost of one pound of jelly beans is $2.75.

Answer: this is hard
Step-by-step explanation:
Which of the following combinations of side lengths would NOT form a triangle with vertices X, Y, and Z?
OA. XY = 15 mm, YZ 10 mm, X
,
OB. XY = 18 mm, YZ = 10 mm, XZ = 25 mm
XY = 18 mm, Z= = 13 mm, XZ = 22 mm
XY 15 mm, YZ = 10 mm, XZ = 22 mm
C.
OD.
XZ = 28 mm
The combinations of side lengths that would not form a triangle with vertices X, Y, and Z is A. XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.
How can we determine combinations of side lengths that would not form a triangle?We shall us the triangle inequality theory for this problem.
According to this theory, the addition of the lengths of any two sides of a triangle must be greater than the length of the third side.
Therefore, for the sides XY, YZ, and XZ to form a triangle, we must have:
XY + YZ > XZ
YZ + XZ > XY
XZ + XY > YZ
We can check each option to see if it satisfies these conditions:
A. XY = 15 mm, YZ = 10 mm, XZ = 28 mm
15 + 10 > 28 (not satisfied)
10 + 28 > 15 (satisfied)
28 + 15 > 10 (satisfied)
Option A does not satisfy the condition XY + YZ > XZ, so it would not form a triangle.
B. XY = 18 mm, YZ = 10 mm, XZ = 25 mm
18 + 10 > 25 (satisfied)
10 + 25 > 18 (satisfied)
25 + 18 > 10 (satisfied)
Option B satisfies all the conditions, so it would form a triangle.
C. XY = 18 mm, YZ = 13 mm, XZ = 22 mm
18 + 13 > 22 (satisfied)
13 + 22 > 18 (satisfied)
22 + 18 > 13 (satisfied)
Option C satisfies all the conditions, so it would form a triangle.
D. XY = 15 mm, YZ = 10 mm, XZ = 22 mm
15 + 10 > 22 (satisfied)
10 + 22 > 15 (satisfied)
22 + 15 > 10 (satisfied)
Option D satisfies all the conditions, so it can form a triangle.
Therefore, the combinations that would not form a triangle is A, where XY = 15 mm, YZ = 10 mm, and XZ = 28 mm.

How to express the logarithm eqaution as a single logarithm?Since we have the logarithm expression
3/2㏑4x⁶ - 2/5㏑2y²⁵
To simplify, we proceed as follows
First, we use the power law of logarithm which states that
n㏑x = ㏑xⁿ
So, using this, we have that
3/2㏑4x⁶ - 2/5㏑2y²⁵ = ㏑4x⁶ - 2/5㏑2y²⁵

12. David is building a ramp to go up the step into his
house. The step is 2 foot high. The ramp is 7.3 feet long and
the end of the ramp will be 7.0 feet from the step. What is
the slope of the ramp? Express the answer as a fraction.
(2/7.3 or 7.3/2 or 2/7 or 7/2 or 7/7.3 or 7.3/7)
Answer: The slope of the ramp is defined as the rise over the run, where the rise is the height of the step (2 feet) and the run is the horizontal distance from the bottom of the ramp to the step (7.0 feet). However, since the ramp is not straight but inclined, we need to use the length of the ramp (7.3 feet) to calculate the actual horizontal distance it covers.
Therefore, the run of the ramp is the square root of the difference between the length of the ramp squared and the height of the step squared:
run = sqrt(7.3^2 - 2^2) = sqrt(52.29 - 4) = sqrt(48.29) ≈ 6.95 feet
Now we can calculate the slope of the ramp:
slope = rise / run = 2 / 6.95 = 0.2885 ≈ 2/7
Therefore, the slope of the ramp is approximately 2/7.

The volume of the prism in cubic inches is 4/9 cubic in if each cube in the prism measures 1/3 inch on one side.
Hence, the correct option is A.
If each cube in the prism measures 1/3 inch on one side, then the volume of one cube is (1/3)³ = 1/27 cubic inches.
To find the volume of the prism, we need to know how many cubes are in the prism. Let's assume the prism has dimensions of length L, width W, and height H, all measured in units of cubes. Then, the total number of cubes in the prism is L × W × H.
Therefore, the volume of the prism in cubic inches is
Volume = (L × W × H) × (1/27) cubic inches
From the given figure, we can find
L = 3 inch
W = 2 inch
H = 2 inch
Substitute the values in formula to find the volume
= (3 × 2 × 2) × (1/27) cubic inches
= 4/9 cubic inches
Hence, the correct option is A.

y - y₁ = m(x - x₁)
Where:
x and y represent the data points.m represent the slope.Since the equation of this line is parallel to the line x + 2y = 4, the slope is given by;
Slope, m = -0.5
y - y₁ = m(x - x₁)
y + 3.5 = -0.5(x - 1)
y = -0.5x - 3
Since the equation of this line is perpendicular to the line 5x + 2y + 2 = 0, the slope is given by;
Slope, m = -5/2
m₁ × m₂ = -1
-5/2 × m₂ = -1
Slope, m₂ = 2/5
y - y₁ = m(x - x₁)
y - 2 = 2/5(x + 5)
y = 2x/5 + 4
Since the equation of this line passes through the origin (0, 0) and parallel to the line 4x - 5y = 10, the slope is given by;
Slope, m = 4/5
y - y₁ = m(x - x₁)
y - 0 = 4/5(x - 0)

College p has 32% less
The initial sum of the number of students in College P and College Q is 5040.
We have,
Let's assume that the number of students in college Q is represented by Q, and the number of students in college P is represented by P:
P = Q - 0.32Q = 0.68Q
We also know that if 960 more students enroll in college P, the two colleges will have the same number of students.
So, we can set up another equation:
P + 960 = Q
We can substitute the first equation into the second equation to eliminate P:
0.68Q + 960 = Q
Solving for Q, we get:
0.32Q = 960
Q = 3000
The initial number of students in college Q was 3000.
We can use this value to find the initial number of students in college P:
P = 0.68Q = 0.68(3000) = 2040
So, the initial sum of the number of students in College P and College Q is:
P + Q = 2040 + 3000 = 5040
