Nick is making cookies the recipe requires 2 1/3 cup of flour and 1/6 teaspoons of salt. Nick wants to make the recipe using 1 cup of flour. To maintain the ratio, how much salt is required when 1 cup of flour is used?

Answers

Answer:

1 / 14 tsp salt

(1 over 14)

Step-by-step explanation:

Let's set the scale factor as x.

So,

2 1/3 * x = 1

Divide both sides by  2 1/3, which is equal to 7/3

x = 1 / (7/3)

x = 3 / 7

So, amount of salt would be written as:

(1/6) * (3/7) =

(1/2) * (1/7) =

1 / 14 tsp salt

Datos

ayudenme plis​

Answers

Answer:

a. Velocidad = 16 m/s

b. Deceleración = 0.64 m/s²

Step-by-step explanation:

Dados los siguientes datos;

Tiempo = 25 segundos

Distancia = 400 metros.

a. Para encontrar la velocidad;

Velocidad = distancia/tiempo

Velocidad = 400/25

Velocidad = 16 m/s

b. Para encontrar la desaceleración;

Durante una desaceleración, la velocidad inicial es mayor que la velocidad final.

Deceleración = (v - u)/t

Sabemos que la velocidad final es igual a cero (0) porque el automóvil se detiene.

Deceleración = (0-16)/25

Deceleración = 16/25

Deceleración = 0.64 m/s²

In the figure below, m∠1 = x and m∠2 = x - 8. Which statement could be used to prove that x = 49?

Answers

Answer:

see explanation

Step-by-step explanation:

∠ 1 + ∠ 2 = 90, that is

x + x - 8 = 90

2x - 8 = 90 ( add 8 to both sides )

2x = 98 ( divide both sides by 2 )

Answer:

Step-by-step explanation

3=e and 5=f (but I guess u accidentally put a plus sign)

so 2e= 6 and 3f=15, and 6-15=-9 so this checks out

Next e=3 and 3f=15 (that 5 in the second problem should be an f)               and 3+15-18 again is checks out so 3,5 must be correct yada yada yada goodnight.
