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)

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

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

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

Answer:

The answer would be 29.7

Step-by-step explanation:

The reason is would be 29.7 is when you are rounding to the nearest tenth, you take the first number to the right after the decimal and if it is 4 or below it stays the same and 5 above and it goes up one.

I hope this is right. Let me know if this helped!!

Answer:

C: 29.7

Step-by-step explanation:

You'd start by looking at the hundreths, which is 0.04. Since that is less than 0.05, it wont round up, but instead down. Hence, 29.7 is the answer.

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:

B

Step-by-step explanation:

The 20th term of the sequence that begins as -4,8,-16,32,...is 2097152.

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

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.

Step-by-step explanation:

Step-by-step explanation:

the first person is right

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:

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
