To find out how much of each mixture Donny should combine to make 6 kg of a mixture of 33% almonds, we need to use a system of equations. Let x be the amount of the first mixture and y be the amount of the second mixture.
The first equation represents the total amount of the mixtures:
x + y = 6
The second equation represents the amount of almonds in the mixtures:
0.40x + 0.25y = 0.33(6)
Solving the system of equations, we get:
0.40x + 0.25y = 1.98
0.40x + 0.25(6 - x) = 1.98
0.40x + 1.50 - 0.25x = 1.98
0.15x = 0.48
x = 3.2
Substituting the value of x back into the first equation:
3.2 + y = 6
y = 2.8
So Donny should combine 3.2 kg of the first mixture and 2.8 kg of the second mixture to make 6 kg of a mixture of 33% almonds.

Now, the above assumption results a right angled triangle ABC, with base 3 cm and hypothenuse 4 cm. We have to calculate the area of triangle ABC. First we determine the height of ∆ABC. Using the Trigonometric functions,
tan 30° = AB/BC
=> tan 30° = AB/3
=> AB = 3 tan 30°
=> AB = 3(1/√3) = √3 cm
Now, area of triangle ABC = (1/2)× base length × height.
= (1/2) × √3 cm × 3 cm
= 3√3/2 cm²
Hence, the required area is 3√3/2 cm².

Prove that, for a, b, and c ∈ Z, a > b and c > 0 =⇒ ac
> bc (part 3 of Proposition 2)
Our assumption is false
We can prove this statement by contradiction. Suppose a > b and c > 0 but ac < bc.
Since a > b, then a - b > 0. Multiplying both sides by c > 0 gives (a - b)c > 0.
We can then add bc to both sides to get (a - b)c + bc > bc.
Since we assumed that ac < bc, then (a - b)c < 0, and thus (a - b)c + bc < bc, which contradicts the previous result.
Therefore, our assumption is false, and we can conclude that for a, b, and c ∈ Z, a > b and c > 0 =⇒ ac ≥ bc.

1. Find all real solution(s) to each equation algebraically: (a) - n + √(6n + 19) = 2 (Remember to check your solutions.) (b) x^4 - 20x^2 + 64 = 0
the real solutions to this equation are x = 2√2 and x = -2√2.
Solution:
(a) -n + √(6n + 19) = 2
To find the solution algebraically, we need to isolate the radical on one side of the equation and then square both sides to get rid of the radical.
-n = 2 - √(6n + 19)
(-n - 2)^2 = (2 - √(6n + 19))^2
n^2 + 4n + 4 = 4 - 4√(6n + 19) + 6n + 19
n^2 - 2n - 19 = -4√(6n + 19)
(n^2 - 2n - 19)^2 = (-4√(6n + 19))^2
n^4 - 4n^3 - 18n^2 + 76n + 361 = 96n + 304
n^4 - 4n^3 - 114n^2 + 76n + 57 = 0

to produce c articles each day? (There’s an attached photo to this !)
The equation (bd)/(b-d) = c can be used to determine how many hours a day the remaining women must work in order to produce the same number of articles each day, when some of the women have been released.
What is an equation?An equation is an expression used to relate two or more quantities, usually by using mathematical operators such as addition, subtraction, multiplication and division. An equation typically has an equal sign (=) as its central element, with the left and right sides of the equation representing the two sides of the equation.
The answer to this question can be determined by using the following equation: (bd)/(b-d) = c. This equation is a simple ratio that takes into account the number of hours the women work per day (b), the number of women released (d), and the number of articles produced each day (c).
For example, if a factory had 10 women working 8 hours a day and produced 100 articles each day, and 5 of those women were released, then the equation (8 x 5) / (8-5) = 100 would determine that the remaining women must work 12.5 hours per day in order to produce the same number of articles.
In conclusion, the equation (bd)/(b-d) = c can be used to determine how many hours a day the remaining women must work in order to produce the same number of articles each day, when some of the women have been released.

The identity \[ \frac{1}{\tan x(1+\cos 2 x)}=\csc 2 x \] is proved.
To prove the identity \[ \frac{1}{\tan x(1+\cos 2 x)}=\csc 2 x \], we can use the Double Angle Formula for Cosines and the Pythagorean Identity.
Using the Double Angle Formula for Cosines, we get:
$\cos2x = 2\cos^2 x - 1$
We can then substitute this into the original identity and simplify:
$\frac{1}{\tan x(1+\cos 2 x)}=\frac{1}{\tan x(1+2\cos^2 x - 1)}$
Using the Pythagorean Identity, $\cos^2 x + \sin^2 x = 1$, we get:
$\frac{1}{\tan x(1+\cos 2 x)}=\frac{1}{\tan x(\sin^2 x)}$
Using the inverse tangent function, $\tan^{-1}x = \frac{\pi}{2}-\sin^{-1}x$, and since $\sin 2x = 2 \sin x \cos x$, we can rewrite this as:
$\frac{1}{\tan x(1+\cos 2 x)}=\frac{1}{2 \sin x \cos x}$
Finally, using the definition of cosecant, $\csc x = \frac{1}{\sin x}$, we get:
$\frac{1}{\tan x(1+\cos 2 x)}=\csc 2 x$
Therefore, the identity \[ \frac{1}{\tan x(1+\cos 2 x)}=\csc 2 x \] is proved.

Calculate the volume of the parallelepiped determined by the vectors in R3:
u= i - 2j +3k
v=2i+k
w=4j
The volume of the parallelepiped determined by the vectors u, v, and w is 20.
To calculate the volume of the parallelepiped determined by the vectors u, v, and w, we need to use the scalar triple product. The scalar triple product of three vectors is defined as the dot product of one vector with the cross product of the other two vectors. In this case, the volume of the parallelepiped is given by:
Volume = |u . (v x w)|
Where "." represents the dot product and "x" represents the cross product.
First, let's calculate the cross product of v and w:
v x w = (2i + k) x (4j) = 8k - 4i
Next, let's take the dot product of u and the result of the cross product:
u . (v x w) = (i - 2j + 3k) . (8k - 4i) = -4 + 24 = 20
Finally, we take the absolute value of the result to get the volume of the parallelepiped:
Volume = |20| = 20
Therefore, the volume of the parallelepiped determined by the vectors u, v, and w is 20.

4) The area of icing needed for one red velvet cake with a radius of 13 centimeters and a height of 15 centimeters is approximately 459 square centimeters.
What is the surface area of the cylinder?
The surface area of a cylinder is the total area of all its curved and flat surfaces. It is given by the formula:
Surface Area = 2πr² + 2πrh
To answer these questions, we need to use the formula for the surface area of a cylinder:
Surface Area = 2πr² + 2πrh
where r is the radius of the circular base of the cylinder, h is the height of the cylinder, and π is the mathematical constant pi.
We are given that the container was covered in plastic wrap during manufacturing. We are not given the dimensions of the container, but we can assume it is a cylinder. Therefore, we need to calculate the surface area of the cylinder. We are not given the values of r and h, so we cannot calculate the surface area directly. Therefore, we cannot determine the answer to this question.
We are given the net of a cylinder with a labeled radius of 4 inches and a labeled height of 3 inches. To find the surface area of the cylinder, we need to use the formula:
Surface Area = 2πr² + 2πrh
Substituting r = 4 and h = 3, and using π ≈ 3.14, we get:
Surface Area = 2(3.14)(4²) + 2(3.14)(4)(3) = 100.48 in²
Therefore, the surface area of the cylinder is 100.48 in².
We are given a cylinder with a labeled radius of 1 and three-fourths centimeters and a labeled height of 3 and one-fourth centimeters. To find the surface area of the cylinder, we need to use the formula:
Surface Area = 2πr² + 2πrh
Substituting r = 1.75 and h = 3.25, we get:
Surface Area = 2(3.14)(1.75²) + 2(3.14)(1.75)(3.25) = 35.875π cm²
Therefore, the exact surface area of the cylinder in terms of π is 35 and seven-eighths times pi square centimeters.
We are given a red velvet cake with a radius of 13 centimeters and a height of 15 centimeters. We need to find the area of the circular top of the cake, which is the same as the surface area of a cylinder with radius 13 and height 0. We can use the formula:
Surface Area = 2πr² + 2πrh
Substituting r = 13 and h = 0, we get:
Surface Area = 2(3.14)(13²) + 2(3.14)(13)(0) = 1061.76 cm²
We need to subtract this from the surface area of the whole cylinder (the cake) to find the area of the icing. Using the formula again with r = 13 and h = 15, we get:
Surface Area = 2(3.14)(13²) + 2(3.14)(13)(15) = 1520.6 cm²
Therefore, the area of icing needed for one cake is:
1520.6 - 1061.76 = 458.84 cm²
Rounding this to the nearest square centimeter, we get:
459 cm²
Therefore, approximately 459 square centimeters of icing is needed for one cake.
Hence,
1) Cannot be determined.
2) Surface area of the cylinder with radius 4 inches and height 3 inches is 100.48 square inches.
3) Exact surface area of the cylinder with radius 1 and three-fourths centimeters and height 3 and one-fourth centimeters is 35 and seven-eighths times pi square centimeters.

Maricopa's Success scholarship fund receives a gift of $ 85000. The money is invested in stocks, bonds, and CDs. CDs pay 5.5 % interest, bonds pay 5.2 % interest, and stocks pay 6.4 % interest. Maricopa Success invests $ 20000 more in bonds than in CDs. If the annual income from the investments is $ 4780 , how much was invested in each account?
Maricopa Success invested $ in stocks.
Maricopa Success invested $ in bonds.
Maricopa Success invested $ in CDs.
To solve this problem, we can use a system of equations. Let's represent the amount invested in stocks as x, the amount invested in bonds as y, and the amount invested in CDs as z.
The first equation we can create is the total amount invested:
x + y + z = 85000
The second equation is the difference between the amount invested in bonds and CDs:
y - z = 20000
The third equation is the total interest earned:
0.064x + 0.052y + 0.055z = 4780
We can use substitution to solve this system of equations. Let's rearrange the second equation to solve for y:
y = z + 20000
We can then substitute this value of y into the first equation:
x + (z + 20000) + z = 85000
Simplifying gives us:
x + 2z = 65000
Now, let's substitute the value of y into the third equation:
0.064x + 0.052(z + 20000) + 0.055z = 4780
Simplifying gives us:
0.064x + 0.107z = 3780
We can now use the first and third equations to solve for x and z. Let's rearrange the first equation to solve for x:
x = 65000 - 2z
We can then substitute this value of x into the third equation:
0.064(65000 - 2z) + 0.107z = 3780
Simplifying gives us:
4160 - 0.128z + 0.107z = 3780
Combining like terms gives us:
-0.021z = -380
Solving for z gives us:
z = 18095.24
We can now use this value of z to solve for y:
y = z + 20000 = 18095.24 + 20000 = 38095.24
And finally, we can use the value of z to solve for x:
x = 65000 - 2z = 65000 - 2(18095.24) = 28809.52
So, Maricopa Success invested $28809.52 in stocks, $38095.24 in bonds, and $18095.24 in CDs.

1. The values of x, y, and z are x = 15.5, y = 9.54, and z = 0. 2. The values of x and y are x = 1.4375 and y = 8. 3. The values of x and y are x = 6 and y = 52.5. 4. X can have any value and the triangles will still be similar
1. We are given that ΔPRS is congruent to ΔCFH.
From ΔPRS, we know that:
∠P = 180 - 28 - ∠R
∠P = 152 - 13y
From ΔCFH, we know that CH is the hypotenuse and CF is one of the legs. So, using the Pythagorean Theorem, we have:
CH^2 = CF^2 + FH^2
39^2 = 24^2 + FH^2
FH^2 = 39^2 - 24^2
FH = sqrt(39^2 - 24^2) = 30
Since ΔPRS is congruent to ΔCFH, their corresponding sides are equal. Therefore:
PS = CH = 39
2x - 7 = CF = 24
Solving for x and y:
2x - 7 = 24
2x = 31
x = 15.5
39 = 2x - 7
46 = 2x
x = 23
∠P = 152 - 13y
28 = 152 - 13y
124 = 13y
y = 9.54
Solving for z:
PS = 2x - 7
39 = 2(15.5) - 7
39 = 31
z = 0
Therefore, the values of x, y, and z are x = 15.5, y = 9.54, and z = 0.
2. We are given that ΔABC is similar to ΔDEF. Therefore, the corresponding sides are proportional:
AB/DE = BC/EF = AC/DF
Substituting the given values:
8/(y-6) = 19/(4x-1) = 14/DF
We can solve for x and y using any two of the three ratios.
Let's first solve for x and y using the first two ratios:
8/(y-6) = 19/(4x-1)
Cross-multiplying, we get:
8(4x-1) = 19(y-6)
Expanding the brackets, we get:
32x - 8 = 19y - 114
32x - 19y = -106
Now let's use the third ratio:
14/DF = 8/(y-6)
Cross-multiplying, we get:
14(y-6) = 8DF
Simplifying, we get:
y = (4/7)DF + 6
Substituting this into the equation we got earlier:
32x - 19y = -106
32x - 19[(4/7)DF + 6] = -106
32x - (76/7)DF - 114 = -106
32x - (76/7)DF = 8
Multiplying both sides by 7, we get:
224x - 76DF = 56
Using the equation we got from the third ratio:
14(y-6) = 8DF
14y - 84 = 8DF
14y = 8DF + 84
y = (4/7)DF + 6
Substituting this into the equation we just got:
14[(4/7)DF + 6] = 8DF + 84
8DF + 84 = (56/7)DF + 84
8DF = (56/7)DF
DF = 7
Substituting DF = 7 into the third ratio:
14/DF = 8/(y-6)
14/7 = 8/(y-6)
2 = y-6
y = 8
Now we can substitute y = 8 into the equation we got earlier:
32x - 19y = -106
32x - 19(8) = -106
32x - 152 = -106
32x = 46
x = 1.4375
Therefore, the values of x and y are x = 1.4375 and y = 8.
3. Since ΔZMK ≈ ΔAPY, we know that the corresponding angles are congruent:
m∠M = m∠A
m∠K = m∠Y
Therefore, we can write two equations:
m∠M = 2y + 7
m∠K = 41°
Also, we know that:
m∠M + m∠K + (13x - 37)° = 180°
Substituting the values we have:
112° + 41° + (13x - 37)° = 180°
13x + 116 = 180
13x = 64
x = 4.9231
Substituting x into the third equation:
112° + 41° + (13x - 37)° = 180°
13x + 116 = 180
13(4.9231) + 116 + m∠K = 180
m∠K = 41°
Substituting m∠K = 41° into the second equation:
m∠K = m∠Y
13x - 37 = 41
13x = 78
x = 6
Substituting x into the first equation:
m∠M = 2y + 7
112 = 2y + 7
105 = 2y
y = 52.5
Therefore, the values of x and y are x = 6 and y = 52.5.
4. Since ΔBTS ≈ ΔGHD, we know that the corresponding angles are congruent:
m∠S = m∠H
m∠B = m∠G
Therefore, we can write two equations:
m∠S = 7y + 5
m∠B = m∠G = 21°
Also, we know that:
m∠B + m∠T + m∠S = 180°
Substituting the values we have:
21° + m∠T + 56° = 180°
m∠T = 103°
Now we can use the fact that the sum of the angles in a triangle is 180° to find m∠G:
m∠B + m∠T + m∠G = 180°
21° + 103° + m∠G = 180°
m∠G = 56°
Since we have a pair of similar triangles, we can use their side lengths to set up a proportion:
BS/BT = GD/GH
Substituting the given values:
25/31 = (4x-11)/GH
Solving for GH:
GH = (31/25)(4x-11)
Now we can use the fact that the sum of the angles in a triangle is 180° to find m∠H:
m∠G + m∠H + m∠D = 180°
56° + m∠H + 90° = 180°
m∠H = 34°
Substituting the values we have:
m∠S = 7y + 5
56 = 7y + 5
51 = 7y
y = 7.2857
Substituting y into the first equation:
m∠S = 7y + 5
m∠S = 7(7.2857) + 5
m∠S = 59
Now we can use the fact that the sum of the angles in a triangle is 180° to find m∠T:
m∠B + m∠T + m∠S = 180°
21° + m∠T + 59° = 180°
m∠T = 100°
Now we can use the fact that we have a pair of similar triangles to find x:
BS/BT = GD/GH
25/31 = (4x-11)/GH
25/31 = (4x-11)/((31/25)(4x-11))
Simplifying:
25/31 = 25/31
Therefore, x can have any value and the triangles will still be similar.

7
of the remaining distance on Sunday. What fraction of the total distance to her aunt’s house was traveled on Sunday?
Stella's family traveled 2/5 of the total distance to her aunt's house on Sunday.
What is distance ?
Distance is a physical quantity that refers to the length between two points or the amount of space between them. It is typically measured in units such as meters, kilometers, miles, or feet.
Stella's family traveled 3/10 of the distance to her aunt's house on Saturday. Therefore, the remaining distance they had to travel was:
1 - 3/10 = 7/10
On Sunday, they traveled 4/7 of the remaining distance. Therefore, the total distance traveled on Sunday is:
(4/7) x (7/10) = 4/10
Simplifying the fraction 4/10 gives 2/5.
Therefore, Stella's family traveled 2/5 of the total distance to her aunt's house on Sunday.

The points P(7, -3), Q(0,3), R(-9,5), and S(-2,-1) form a quadrilateral. Find the desired slopes and lengths, then fill in the words that BEST identifies the type of quadrilateral.
The quadrilateral formed from the points P(7, -3), Q(0,3), R(-9,5), and S(-2,-1) is a rhombus.
To find the desired slopes and lengths, we can use the slope formula and the distance formula. The slope formula is (y₂ - y₁)/(x₂ - x₁) and the distance formula is √((x₂ - x₁)² + (y₂ - y₁)²).
Slope of PQ = (3 - (-3))/(0 - 7) = 6/(-7) = -6/7
Slope of QR = (5 - 3)/(-9 - 0) = 2/(-9) = -2/9
Slope of RS = (-1 - 5)/(-2 - (-9)) = (-6)/(7) = -6/7
Slope of SP = ((-3) - (-1))/(7 - (-2)) = (-2)/(9) = -2/9
Length of PQ = √((0 - 7)² + (3 - (-3))²) = √(49 + 36) = √85
Length of QR = √((-9 - 0)² + (5 - 3)²) = √(81 + 4) = √85
Length of RS = √((-2 - (-9))² + ((-1) - 5)²) = √(49 + 36) = √85
Length of SP = √((7 - (-2))² + ((-3) - (-1))²) = √(81 + 4) = √85
Since the opposite slopes are equal and all of the lengths are equal, the quadrilateral is a rhombus.
