Answer:

Yes, the boats are safe to ride.

Step-by-step explanation:

40 (4) + 12 (2) ≤ 500

160 + 24 ≤ 500

184  ≤ 500

184 is less than 500.

because I was not sure if you had 9 adults instead of 2, this is the answer:

40 (4) + 12 (9) ≤ 500

160 + 108 ≤ 500

268 ≤ 500

268 is less than 500

Maritza esta vendiendo una bicicleta seminueva que ya no utiliza. Como le costo doscientos soles, incluido IGV, ahora la venderá
Sophie [7]

Answer:

Ok, primero, como lo deducimos gráficamente?

Sigamos estos pasos.

Dibujemos en una recta, la distancia entre el punto 0 soles y el precio de la bicicleta = 200 soles.

200 soles representa el 100%.

Ella lo quiere vender al 80% (o le quiere restar el 20%).

Entonces, con una regla, medir la distancia entre 0 soles y 200 soles.

Dividir esa cantidad por 10. (cada una de estas cantidades va a representar un 10%)

Multiplicar eso por 8.

Esa cantidad es el equivalente al 80% del precio de la bicicleta.

Abajo hay un dibujo donde se ve el método.

Una forma mas matemática de resolverlo es:

200 soles = 100%.

x soles = 80%

x es el precio al que ella va a vender la bicicleta:

Veamos el cociente de esas dos ecuaciones:

200/x = 100%/80%

x = 200*(80%/100%) = 160

Ella vendería la bicicleta en 160 soles.

20. The simplest form of 9/4+(-19/3)=​
ololo11 [35]

Answer:

-\frac{49}{12}

Step-by-step explanation:

\frac{9}{4}+(-\frac{19}{3})

\frac{9}{4}-\frac{19}{3}

(Must make both denominators same number, which would be 12)

3(\frac{9}{4})-(\frac{19}{3})4

(Multiply both the numerator and denominator of by 3 and/or 4 for the specific fraction)

\frac{27}{12}-\frac{76}{12}

(Subtract the fractions)

-\frac{49}{12}

That's how you get your answer!

Will give brainliest
luda_lava [24]

Answer:

P (A and B)=8/9

Events A and B are not dependent.

Step-by-step explanation:

Probability of A AND B means the the probability (favorable outcomes divided by total) of choosing someone who has/did BOTH A and B (not neither or only one of them). 16 did both, so the probability is 16/18 /2/2 = 8/9.

The events are independent (not dependent) because choosing A does not affect choosing B.
