Which of the following choices shows the proper use of the distributive property?
A. -2(6x - y) = -12x + 2y
B. -2(6x - y) = 12x + 2y
C. -2(6x - y) = 12x - 2y
D. -2(6x - y) = -12x - 2y
What’s the answer

Answer:

<1 = <3 = 67

<2 = <4 = 113

Step-by-step explanation:

<1 and <3 are equal because they are vertical angles

<1 = <3 = 67

<2 and <3 form a straight line so they add to 180

<2+ 67 = 180

<2 = 180-67

<2 = 113

<2 and <4 are equal since they are vertical angles

<2 = <4 = 113

Answer:

1695.6 cubic feet

Step-by-step explanation:

Given that,

The corn fills 25% of the height of the silo.

The diameter of silo, d = 12 feet

Radius, r = 6 feet

Height, h = 60 feet

The volume of the part of the silo that is filled with corn is given by :

[tex]V=25\%\ of\ \pi r^2 h\\\\=\dfrac{25}{100}\times 3.14\times 6^2\times 60\\\\V= $$1695.6\ feet^3[/tex]

So, the required volume is equal to 1695.6 cubic feet.

Answer:

3 ft

Step-by-step explanation:

We can use a ratio to solve

Using x as the length of the model

1           x

----- = -----------------

Answer:  327.60 dollars

Explanation:

There are about 52 weeks in a year (note that 365/7 = 52.14)

So that means it costs a total of 52*6.30 = 327.60 dollars to run the fridge for a full year.

Answer:

It costs $328.50 to run the refrigerator for 365 days

Step-by-step explanation:

Recall that there are seven days in a week and 52 weeks in a year

The given rate is

$6.30

-----------

7 days

To find the cost of running the refrigerator for 365 days, multiply this given rate by 365 days:

$6.30

----------- * 365 days = $328.50

7 days

It costs $328.50 to run the refrigerator for 365 days (1 year, 52 weeks).

Answer:4

Step-by-step explanation:

The Mean Absolute Deviation is 4 from the data given

Answer:

300 square inches

Step-by-step explanation:

Area of a Trapezoid = 1/2 (b1 + b2 ) × h

h = height 20 inches

b1 = First base = ?

b2 = Second base = ?

From the Question

b1 + b2 = 30 Inches

Hence,

Area of the Trapezoid = 1/2 (30) × 20

= 1/2 × 30 inches × 20 inches

= 300 square inches

The Area of the Trapezoid = 300 Square inches

Answer:

A. The monthly payment is $202.85.

B. The total amount paid over the term of the loan is $36,513.60.

C. The percentage paid toward the principal is 54.77%, while the percentage paid for interest is 45.23%.

Step-by-step explanation:

A. Calculate the monthly payment.

This can be calculated using the formula for calculating the present value of an ordinary annuity as follows:

PV = P * ((1 - (1 / (1 + r))^n) / r) …………………………………. (1)

Where;

PV = Present value or principal or student loan = $20,000

P = Monthly payment = ?

r = Monthly rate = APR /12 = 9% / 12 = 0.09 / 12 = 0.0075

n = number of months = 15 * 12 = 180

Substituting the values into equation (1) and solve for P, we have:

$20,000 = P * ((1 - (1 / (1 + 0.0075))^180) / 0.0075)

$20,000 = P * 98.5934088350577

P = $20,000 / 98.5934088350577 = $202.85

Therefore, the monthly payment is $202.85.

B. Determine the total amount paid over the term of the loan.

Total amount paid = Monthly payment * Number of months = $202.85 * 180 = $36,513.60

Therefore, the total amount paid over the term of the loan is $36,513.60.

C. Of the total amount paid what percentage is paid toward the principal and what percentage is paid for interest.

Percentage paid toward the principal = Principal / Total amount paid = $20,000 / $36,513.60 = 0.5477, or 54.77%

Percentage paid for interest = 100% - Percentage paid toward the principal = 100% - 54.77% = 45.23%

Therefore, the percentage paid toward the principal is 54.77%, while the percentage paid for interest is 45.23%.

Answer:

22is the answer cuz it is

Answer:

Step-by-step explanation:

using pythagoras theorem

a^2 + b^2 = c^2

here 4 and 9 are the legs of the right angled triangle so let them be a and b respectively . third side is the hypotenuse because it is opposite to 90 degree so let it be c.

4^2 + 9^2 = c^2

16 + 81 = c^2

97 = c^2

[tex]\sqrt{97} = c[/tex]

Answer:

  a.  f(x) = (4x +5)(x -3)

  b.  x-intercepts: {-1.25, +3}

  c.  f(x) goes to +infinity as x goes to ±infinity

  d. plot the x-intercepts, the vertex, and a few other points; draw a smooth curve through them

Step-by-step explanation:

a. Here, you're looking for factors of (4)(-15) = -60 that have a sum of -7. Those factors will be -12 and +5, so we can factor the function as ...

  f(x) = (4x -12)(4x +5)/4

  f(x) = (x -3)(4x +5)

__

b. The x-intercepts are the values of x that make the factors zero:

  x -3 = 0   ⇒   x = 3 . . . . (add 3)

  4x +5 = 0   ⇒   x = -5/4 . . . . (add -5, divide by 4)

__

c. As with all even-degree polynomials with positive leading coefficients, the end behavior of f(x) matches that of |x|:

  as x → ∞, f(x) → ∞

  as x → -∞, f(x) → ∞

__

d. The vertex of the function will be located halfway between the x-intercepts, at x = (3-5/4)/2 = (7/4)/2 = 7/8. The value of f(x) there is ...

  f(7/8) = (4(7/8) +5)(7/8 -3) = -289/16 = -18.0625

Since the leading coefficient is 4, the normal x^2 function behavior is stretched vertically by a factor of 4. So, additional points would be

  x = 7/8 ±1, f(x) = -18.0625 +4·1 = -14.0625

  x = 7/8 ±2, f(x) = -18.0625 +4·2^2 = -2.0625

The answers of part B locate two points on the graph, and help find the vertex. The answer of part C confirms the graph as opening upward.

Additional comment

I find a graphing calculator to be very helpful finding the roots and making the graph.

Answer:

x = 23

Step-by-step explanation:

Sum of 25 and x = 48

25 + x = 48

Subtract 25 from both sides

25 - 25 cancels out

48 - 25 = 23

We would be left with x = 23

Answer:

[tex]x =23[/tex]

Step-by-step explanation:

Sum of 25 and x

[tex]25 + x[/tex]

Sum of 25 and x is 48

[tex]25 + x = 48[/tex]

Now lets simply Solve the equation

[tex]25 + x = 48 \\ x = 48 - 25 \\ x =23[/tex]

Step-by-step explanation:

Answer:

D.3.5

Step-by-step explanation:

4x+2y=10(given)

2x+y=5

y=5-2x-----(1)

y=2x-1------(2)(given)

Since the left side of the equations are the the same,

5-2x=2x-1

4x=6

x=1.5

Sub x=1.5 into eq(1),

y = 5-2(1.5) = 5-3 = 2

so, x+y = 1.5+2 = 3.5

Answer:

4x+2y=10

y=2x-1

4x+2(2x-1)=10

4x+4x-2=10

8x=10+2

8x=12

8x÷8=10÷8

x=1,25

&

y=2x-1

=2(1.25)-1

=1.5

x+y=1.25+1.5

=2,75

Answer:

d(x)  =  - 2666.67*a  +  42000

Step-by-step explanation:

Vamos a llamar a d(x) la ecuación de la demanda de CD, entonces como la relación entre las dos variables es lineal la ecuación de la demanda es del tipo:

d(x) = a*x  + b        (1)

en esa relación a es la pendiente de la recta y b es el intercepto con el eje y que en este cas es el eje de valores de d(x).

Tenemos dos condiciones que cumplir y dos incógnitas que determinar ( a y b).

Cuando el precio ( x = 18 $ ) el monto de d(x)  es de 10000 entonces por sustitución en la ecuación general (1)

10000 = 18*a  +  b   (2)

Y cuando   (  x  =  12  $) d(x) =  26000

26000 = 12*a  +b    (3)

Resolviendo para a y b el sistema de dos ecuacions con dos incógnitas tenemos:

restando  ec 3  -  ec 2

16000 =  - 6*a

de donde   a = - 16000/6

a =  - 2666.67

Llevando ese valor a ec 2

10000  =  12 *(- 2666.67) + b

10000 + 32000 = b

b  = 42000

Finalmente la ecuación buscada es:

d(x)  =  - 2666.67*a  +  42000

Como la pendiente es negativa significa que d(x) va decreciendo cuando x va en aumento
