Slove:33/29=46/x. Try to find the answer.

Tju [1.3M]

Answer:

$x=40\frac{14}{33}$

Step-by-step explanation:

we have

$\frac{33}{29}=\frac{46}{x}$

Solve for x

Multiply in cross

$(33)(x)=(46)(29)$

Divide by 33 both sides (Division Property of Equality)

$x=46(29)/33$

$x=\frac{1,334}{33}$

Convert to mixed number

$x=\frac{1,334}{33}=\frac{1,320}{33}+\frac{14}{33}=40\frac{14}{33}$

yuradex [85]

Answer:

The probability of losing weigth given that the sandwich was ordered is 80%.

Step-by-step explanation:

The probability of a regular costumer ordering the sandwich is said to be 50% and the probability of someone ordering that sandwich and losing weight is 40%. So we the probability of someone losing weigth if the sandwich was ordered is:

sandwich and losing weigh = (ordering sandwich)*losing weigth

losing weigth = (sandwich and losing weigth)/(ordeing sandwich)

losing wiegh = 40%/0.5 = 80%

The probability of losing weigth given that the sandwich was ordered is 80%.
