préstamo en 36 meses a un interés del 5.8%. Calcula la cantidad total a pagar
requerida del préstamo.
Answers
Answer:
El monto total a devolver por parte de Josean Hernández será de $40,227.2, y lo devolverá en 36 cuotas de $1,117.42 cada una.
Step-by-step explanation:
En tanto Josean Hernández solicitó un préstamo de $38,400, y acordó con la financiera devolverlo durante 36 meses a un interés del 5.8%, para determinar la cantidad total a pagar y el monto de cada cuota, es necesario realizar el siguiente cálculo:
(38,400 x 5.6 / 100) + 38,000 = X
2,227.2 + 38,000 = X
40,227.2 = X
40,227.2 / 36 = 1,117.42
Así, el monto total a devolver por parte de Josean Hernández será de $40,227.2, y lo devolverá en 36 cuotas de $1,117.42 cada una.

Answer:
3 ( 5a - 2b + 12)
Step-by-step explanation:
15 = 3 * 5
6 = 2 * 3
36 = 2 * 2 * 3 * 3
GCF = 3
15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)
= 3 ( 5a - 2b + 12)
Answer:
3 ( 5a - 2b + 12)
Step-by-step explanation:
15 = 3 * 5
6 = 2 * 3
36 = 2 * 2 * 3 * 3
GCF = 3
15a - 6b + 36 = (3* 5 * a) - (3 *2 * b) + (3 * 12)
= 3 ( 5a - 2b + 12)

Andrew, who is ill, takes vitamin pills. Each day, he must take at least 16 units of myra X, at least 5 units of myra Y, and at least 20 units of myra Z. He can choose between tablets and capsules. Each tablet contains 8 units of myra X, 1 unit of myra Y, and 2 units of myra Z, while each capsule contains 2 units of myra X, 1 unit of myra Y and 7 units of myra Z. The cost per tablet is Php15, and Php30 per capsule. How many tablets and capsules should he buy in order to minimize his cost?
Answers
Answer:
z (min) = 105
x₁ = 3
x₂ = 2
Step-by-step explanation:
Let´s call x₁ (number of tables) and x₂ ( number of capsules)
assuming it is only possible to get a whole table or capsule we have:
Table x₁ 8 u myra X 1 u of myra Y and 2 u of myra Z
Capsule x₂ 2 " 1 " and 7 u "
Objective function
z = 15* x₁ + 30* x₂ to minimize
First constraint ( Myra X )
8*x₁ + 2*x₂ ≥ 16
Second constraint ( Myra Y )
x₁ + x₂ ≥ 5
Third constraint ( Myra Z )
2*x₁ + 7*x₂ ≥ 20
General constraints x₁ ≥ 0 x₂ ≥ 0 both integers
Then the model is:
z = 15 * x₁ + 30 * x₂ to minimize
Subject to
8*x₁ + 2*x₂ ≥ 16
x₁ + x₂ ≥ 5
2*x₁ + 7*x₂ ≥ 20
x₁ ≥ 0 x₂ ≥ 0 both integers
As the constraints, all are of the form ≥ we have to subtract surplus variables sₐ and add artificial variables Aₐ
sₐ ≥ 0 Aₐ ≥ 0
The first table is
z x₁ x₂ s₁ s₂ s₃ A₁ A₂ A₃ = Cte
1 - 15 - 30 0 0 0 M M M = 16
0 8 2 -1 0 0 1 0 0 = 5
0 1 1 0 -1 0 0 1 0 = 20
0 2 7 0 0 -1 0 0 1 = 20
Using AtoZmax and after 6 iterations we find
z (min) = 105
x₁ = 3
x₂ = 2

What mathematical formula do you use for the following question. A rectangle whose perimeter is 104 feet has a length that is 12 feet longer than its width what is the area of the rectangle. The answer is 640 square feet 20 feet wide by 32 feet long.
Answers
Answer:
Width = 20 inches and Length = 32 inches
Area of rectangle = 640 feet²
Step-by-step explanation:
Perimeter of rectangle = 104 feet
Let width of rectangle = x
Length of rectangle = x+12
We need to find area of rectangle.
First we need to find value of x
The formula used to calculate perimeter of rectangle is: [tex]Perimeter= 2(Length+Width)[/tex]
Putting values and finding x
[tex]Perimeter= 2(Length+Width)\\104 = 2(x+12+x)\\104=2(2x+12)\\104=4x+24\\4x=104-24\\4x=80\\x=\frac{80}{4}\\x=20[/tex]
So, Value of x= 20
So, Width x= 20 inches
Length = x+12 = 20+12 = 32 inches
So, Width = 20 inches and Length = 32 inches
Now finding Area
The formula used is: [tex]Area=Length\times Width[/tex]
Putting values and finding area
[tex]Area=Length\times Width\\Area=20\times 32\\Area=640 \ feet^2[/tex]
Area of rectangle = 640 feet²

Chi has $11:30 in dimes and quarters. The number of dimes is three more
than three times the number of quarters. How many of each are there?
DO NOT COPY AND PASTE. THE ANSWER IS 63 DIMES AND 20 QUARTERS. HOW DO I GET THIS.
Answers
Answer:
To solve this question, we first have to know that we are trying to assemble
and solve equations with two variables: x
and y.
Assuming x
is the number of dimes and y
is the number of quarters, we
can assemble the equations.
since the number of dimes is 3 more than three times the number of quarters,
we get x=3y+3.
Additionally, multiplying the number of dimes by 0.1 and the number of
quarters by 0.25,
we get the total value of x
and y
which appears by this
equation 0.1x+0.25y=11.30
.
Substituting the value of x
in the second equation, we get 0.1(3y+3)+
0.25y=11.30
.
Solving this equation, we get that the value of x,
we get x=3×20+3=
Using the first equation to get the value of x,
we get x=3×20+3=
60+3=63
dimes.

Answer:
∠CDF = 54
Step-by-step explanation:
In ΔAEB,
AE ≅ AB
∠ABE = ∠E = x {Angles opposite to equal sides are equal}
∠EAB + ∠E +∠ABE = 180 {angle sum property of triangle}
26 + x + x = 180
26 + 2x = 180
2x = 180 - 26
2x = 154
x = 154/2
x = 77
∠ABE = ∠E = 77
In quadrilateral AECF
∠A + ∠E + ∠C + ∠F = 360
90 + 77 + ∠C + 90 = 360
∠C + 257 = 360
∠C = 360 - 257
∠C = 103
∠FCD + ∠BCD = ∠C
∠FCD + 67 = 103
∠FCD = 103 - 67
∠FCD = 36
ΔFCD,
∠FCD + ∠CDF + ∠CFD = 180
36 + ∠CDF + 90 = 180
∠CDF + 126 = 180
∠CDF = 180 - 126
∠CDF = 54

What is a geometric progression?
It is a type of sequence in which all the elements have common ratio. To calculate the common ratio we apply the following formula:
Ratio=a n/ a n-1
How to solve a geometric progression?
If we carefully watch our sequence we will be able to find that it is a geometric progression because all the terms have common ratio of -2.
To calculate the 20th term we will apply the formula:
20th term =[tex]ar^{20-1}[/tex]
=-4* [tex](-2)^{19}[/tex]
=-4*-524288
=2097152
Hence the 20 th term is 2097152.

Parallelogram
Step-by-step explanation:
Observation 1:
the sides do not have the same measure √53≠√68 so is NOT a square and NOT a rhombus
Observation 2:
the opposite sides are congruent
AB=CD=√53, and BC=DA=√68
Observation 3:
lines that have the same slope are parallel so opposite sides are also parallel
slope of AB =slope of CD =-2/7, and slope of BC=slope of DA=8/2
so we have 2 pair of sides congruent and parallel but to decide if is a parallelogram or rectangle we need to see if the adjacent sides form 90° or not
Observation 4:
lines that are perpendicular form 90° and their slope is negative reciprocal.
AB slope =-2/7 and slope of BC =8/2 so are NOT perendicular therefore is a parallelogram
