Can someone help me ?please

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).

Answer:

$25

Step-by-step explanation:

Let X = total cost of game

         (3/5) X = $15

Multiply both sides of equation by 5/3

  (5/3)(3/5) X = (5/3) $15

                  X = $25

cost of game is $25

Answer:

2:5.

Step-by-step explanation:

Number of misses = 56 - 16 = 40.

Ratio = 16:40

- which simplifies to   (16/8) : (40 / 8)

= 2:5.

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

Answer:

-4 , -29

Step-by-step explanation:

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

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

Step-by-step explanation:

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.

Tip = $28.72 x 15% = $4.308

=> Final cost = $28.72 + $4.308 = $33.208

Answer:

33.03

Step-by-step explanation:

you multiply 28.72 by 15%or (.15) you will get 4.308, then you add 4.308 and 28.72 and you will get 33.028 then you round it up and get 33.03

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.

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

Step-by-step explanation:

if 1 had the number 108 2 would be 72 because both have to equal 180 also say 3 is right under 1 also on the same line it would be also 72 and 4 also on the same line would be 72 .

5 on a different line would be 108 and 6 on the same line as number 5 would be 72 also 7 would be 108 and 8 would be 82
