Find x ÷ y, if x = 3 5/6 and y = 3 3/5 . Express your answer in simplest form.

Answers

Answer:

Step-by-step explanation:

convert 3 5/6 and 3 3/5 into a improper fraction

x=23/6 and y = 18/5

23/6 ÷ 18/5 multiply both sides by 6 to cancel it out

23 ÷ 108/5 multiply both sides by 5 to cancel it out

Step-by-step explanation:

1. The midpoint formula says the coordinates of the midpoint are the average of the endpoints.

x = (x₁ + x₂) / 2

y = (y₁ + y₂) / 2

I'll do #2 and #3 as examples.

2. x = (-4 + 10) / 2 = 3

y = (6 + -10) / 2 = -2

So the midpoint is (3, -2).

3. x = (-3 + -6.5) / 2 = -4.75

y = (-8 + -4.5) / 2 = -6.25

So the midpoint is (-4.75, -6.25).

En la casa de Juan, van a pedir pizza para la comida, pero cuando la van a pedir se dan cuenta que deben pedirla por perímetro o área de la misma. La mamá dice que es más grande la de perímetro de 100cm y el papá dice que es más la de área de 100cm². ¿Cuál tiene la razón? *

Answers

Responder:

La pizza con un perímetro de 100 cm es más grande ¿verdad?

Explicación paso a paso:

Deja que la pizza tenga forma circular.

Sea el área de la pizza = πd² / 4 y;

Perímetro de la pizza = πd

d es el diámetro de la pizza

Si la madre dice que el que tiene un perímetro de 100 cm es más grande, para estar seguros necesitamos obtener el diámetro de la pizza. La de mayor diámetro será la pizza más grande.

P = 100cm

100 = πd

d = 100 / π

d = 100 / 3,14

d = 31,85 cm

El diámetro de la pizza mamá es de 31,85 cm.

Si el padre dice que el que tiene un área de 100 cm² es más grande, obtengamos también el diámetro para estar seguros.

A = πd² / 4

100 = πd² / 4

400 = πd²

d² = 400 / π

d² = 400 / 3,14

d² = 127,39

d = √127,39

d = 11,29 cm

Por lo tanto, el diámetro de la pizza padre es de 11,29 cm.

Dado que el diámetro de la pizza madre es mayor que el de esa, la pizza con un perímetro de 100 cm es más grande, lo que demuestra que la madre tiene razón.

Multiply both sides of equation by 5/3

(5/3)(3/5) X = (5/3) $15

X = $25

cost of game is $25

Where

(

Answer:

y + 1 = -3(x + 2)

Step-by-step explanation:

Point-slope form is y - y1 = m(x - x1)

m= -3 (-2, -1)

Plug -3 in for the m in the equation, -2 in for x1, and -1 in for y1

y - (-1) = -3(x - (-2))

Subtracting negatives will make them positive

y + 1 = -3(x + 2)

This is the point-slope form, continuing to solve for y will give the y-intercept form.

Y-intercept Form:

y = -3x - 7

DESCRIBE how a power with a zero exponent (a^0) and a power with a negative exponent (a^−n) can be simplified.

Answers

Answer:

[tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]

[tex]a^{0}[/tex] = 1, where a ≠ 0

Step-by-step explanation:

To simplify the exponents, you must put it in positive value

Example:

The simplest form of [tex]2^{-3}[/tex] is to change the exponent from negative value to positive value.

You can do that by reciprocal the number, [tex]2^{-3}=(\frac{1}{2})^{3}[/tex]You can write it [tex]\frac{1}{2^{3}}[/tex], because 1 to any power equal 1

That means if you want to simplify [tex]a^{-n}[/tex], reciprocal a and change the sign of the power from -n to n

The simplest form of [tex]a^{-n}[/tex] is [tex](\frac{1}{a})^{n}[/tex] OR [tex]\frac{1}{a^{n} }[/tex]

For any number, a (a ≠ 0), 1 × a = a, so, the reason that any number to the zero power is 1 because any number to the zero power is just the product of no numbers at all, which is the multiplicative identity, (1)

Example:

The value of [tex](5)^{0}[/tex] = 1, because it is the product of no numbers, so it is equal to the multiplicative identity (1)

That means [tex]a^{0}[/tex] = 1, where a ≠ 0

Very important note:

[tex](0)^{0}[/tex] is undefined value

What values of a and b make this equation true?
(4 + ✓–49) – 2(/(-4)2 + V–324) = a + bi

Answers

Answer:

-4 , -29

Step-by-step explanation:

The values of a and b that make the equation true are -28 and -9, respectively

How to determine the true values of a and b?

The equation is given as:

(4 + √-49) – 2((-4)² + √–324) = a + bi

Evaluate the exponents

(4 + 7i) – 2(16 + 18i) = a + bi

Expand the bracket

4 + 7i – 32 - 16i = a + bi

Collect like terms

4 – 32 + 7i - 16i = a + bi

Evaluate like terms

-28 -9i = a + bi

By comparison, we have:

a = -28 and b = -9

Hence, the values of a and b that make the equation true are -28 and -9, respectively
