2) 1.53

3) 9.48

4) 12.13

5) 19.82

6) 29.70

Step-by-step explanation:

You first must turn all mixed fractions into simple fractions.

Then, find the least common denominator for each problem.

Create fractions with the same denominator.

In your answer, divide the numerator by the denominator.

Answer:

266

Step-by-step explanation:

En Matemáticas, al realizar la operación de División, la regla es la siguiente:

Dividendo ÷ Divisor = Cociente

En la pregunta anterior, se nos da:

Divisor = 19

Cociente = 14

Dividendo =?

Para encontrar el dividendo,

Dividendo = Divisor × Cociente

Por eso,

Dividendo = 19 × 14

= 266

Por lo tanto, el Dividendo = 266

Answer:

Option D. {7 + i√71 / 20, 7 – i√71 / 20}

Step-by-step explanation:

10m² – 7m + 3 = 0

Using formula method, the solution to equation can be obtained as follow:

10m² – 7m + 3 = 0

Coefficient of m² (a) = 10

Coefficient of –7m (b) = –7

Constant (c) = 3

m = –b ±√(b² – 4ac) / 2a

= – –7 ±√((–7)² – 4 × 10 × 3) / 2 × 10

= 7 ±√(49 – 120) / 20

= 7 ±√(–71) / 20

Recall:

–17 = –1 × 17

Thus,

7 ±√(–71) / 20 = 7 ±√(–1 × 71) / 20

Recall:

√–1 = i

Thus,

7 ±√(–1 × 71) / 20 = 7 ± i√71 / 20

= 7 + i√71 / 20 or 7 – i√71 / 20

Therefore, the solutions to the equation are:

{7 + i√71 / 20, 7 – i√71 / 20}

Step-by-step explanation:

The area of a circle is given by

A = pi r^2 where r is the radius

A = pi (6.5)^2

A =42.25 pi

If we approximate pi by 3.14

A = 42.25 * 3.14 =132.665

If we use the pi button

A = 132.7322896

Answer:

1) y = 3/4x - 4

2) x-intercept: (-6,0) y-intercept: (0,8)

3) (-2,7)

4) slope: 2/3

Step-by-step explanation:

1) subtract 3x from both sides, divide -4 from both sides, simplify right side which gives you y = 3/4x -4

2) to get x-inter: plug in 0 for y and solve for x, the equation should look like 4x = -24, divide both sides by 4 which gives you x = -6

get y-inter: plug in 0 for x and solve for y, the equation should look like -3y=-24, divide both sides by -3 which gives you y = 8

3) plug in the points from the choices and go from there

4) slope formula: m = y2-y1/x2-x1

Answer:

a) -1535.5

b) 0

Step-by-step explanation:

A) We do this problem according to its parenthesis. First, let's evaluate the first half, -2[(-1/4)-12(-1)^2]. We have to do (-1)^2 first, because of PEMDAS. (-1)^2 is just 1. Now, our equation is -2[(-1/4)-12*1]. Thus, we get -2[(-1/4)-12] because 12*1 is just 12. Then, we do (-1/4)-12, giving us -12.25. Our equation becomes -2(-12.25). Then, we just get 24.5.

The next half, -5[24+2(-12)^2] is similar. We first evaulate (-12)^2 because of PEMDAS, giving us 144. Then, we have -5[24+2(144)]. 2 times 144 is 288, so we get -5[24+288]. 24 + 288 is 312, so we have -5(312). This finally gives us -1560.

Putting the two together, we get 24.5 - 1560, which is -1535.5.

--------------------------------------------------------------------------------------------------------------B) We substitute a = -1/3 and b = -1 into the equation, -a^2b^2 - 3a^3b^2.

We plug in -1/3 where a is and -1 where b is. So:

-(-1/3)^2(-1)^2 - 3(-1/3)^3(-1)^2.

The tricky part of this problem is making sure you follow PEMDAS. We evaluate the exponents first.

-1/9 * 1  - 3(-1/27) * 1

= -1/9 + 1/9

= 0

Answer:

12.32 units

Step-by-step explanation:

Use the distance formula to find the lengths between two points:

[tex]d=\sqrt{(x_{2} -x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

the distance between (-2, -1) and (-5,-1) is

[tex]\sqrt{(-2-(-5))^2+(-1-(-1))^2}[/tex]

=[tex]\sqrt{3^2+0^2}[/tex]

=[tex]\sqrt{9}[/tex]

=3

the distance between (-2, -1) and (-3, -4) is

[tex]\sqrt{(-2-(-3))^2+(-1-(-4))^2}[/tex]

=[tex]\sqrt{1^2+3^2}[/tex]

=[tex]\sqrt{10}[/tex]

≈3.16

the distance between (-6, -4) and (-3, -4) is

[tex]\sqrt{(-6-(-3))^2+(-4-(-4))^2}[/tex]

=[tex]\sqrt{(-3)^2+0^2}[/tex]

=[tex]\sqrt{9}[/tex]

=3

the distance between (-6, -4) and (-5, -1) is

[tex]\sqrt{(-6-(-5))^2+(-4-(-1)^2}[/tex]

=[tex]\sqrt{(-1)^2+3^2}[/tex]

=[tex]\sqrt{10}[/tex]

≈3.16

Now, add all the sides:

3+3.16+3+3.16=12.32 units

Note: A property of a parallelogram is that it has two pairs of congruent sides, so for this problem, you could solve for 2 different sides, double them, then add and you will get the same thing.
