PLEASE HELP ASAP.....!! 10 pts
ICE Princess25 [194]

Answer:

Possible dimensions are 16 × 4 inches and 32 × 2 inches.

Step-by-step explanation:

We are given that,

Area of the frame = 64 inch² = Length × Width

Now, we have that 64 can be factored as,

64 = 32 × 2

64 = 16 × 4

64 = 8 × 8

Since, the frame is in a rectangular shape. So, we reject the possibility of 8 × 8 inches frame.

Thus, the possible dimensions are,

Set 1: 16 × 4 inches

Set 2: 32 × 2 inches.

PLZ HELP ME!!!! ASAP!!!!!! I WILL GIVE BRAINLIEST!!!!
fenix001 [56]

Answer:

see explanation

Step-by-step explanation:

(1)

To find the unit rate divide the amount by 3

$3.84 ÷ 3 = $1.28 ← unit rate

(2)

Using proportion

$45 → 4 months

$180 → 4 × \frac{180}{45} = \frac{4(180)}{45} = 16 months

(3)

sum the parts of the ratio, 8 + 1 = 9 parts

Divide 90 by 9 to find the value of one part

90 ÷ 9 = 10 ← value of 1 part

Thus

8 × 10 = 80

You have a 1 in 4 chance of winning a game. How would you calculate the probability that you will win 3 times in a row?
klemol [59]

If you have a 1/4 chance of winning, and you win, the next time you win the odds double to 1/8. If you win 1/8, then the odds of winning 3 times in a row are now 1/16, And so on.

Ayuda por favor nesecito este ejercicio
Dimas [21]

La función h(x) es uno a uno en su dominio, por lo tanto es invertible. Y la inversa es:

g(x) = [(x + 3)*4 - 5]/(x + 3 - 1)

<h3>¿Es la función h(x) invertible?</h3>

La función esta definida como:

h(x) = -3 + | (5 - x)/(4 - x) |

El dominio es (4, 5] y el rango es [-3, ∞).

Claramente la función es uno a uno en ese intervalo, como podemos ver en el grafico abajo.

Ahora sabemos que la función es invertible en su dominio, entonces debemos encontrar otra funcion g(x) tal que:

h(g(x)) = x

Entonces debemos tener:

-3 + | (5 - g(x))/(4 - g(x)) | = x

| (5 - g(x))/(4 - g(x)) | = x + 3

Podemos remover el valor absoluto:

(5 - g(x))/(4 - g(x)) = x + 3

5 - g(x) = (x + 3)*(4 - g(x))

5 - g(x) + g(x)*(x + 3) = (x + 3)*4

g(x)*(x + 3 - 1) = (x + 3)*4 - 5

g(x) = [(x + 3)*4 - 5]/(x + 3 - 1)

Esa es la función inversa de h(x).
