Why not? If 4 + 6 = 10, does (4 + 6) X 3 = 10 X 3? Why or why not?

IgorLugansk [536]

Answer:

It would be 10*3

Step-by-step explanation:

If we follow the rule of BIDMAS or BODMAS, they both have Brackets to be done first.

By meaning we must do 4+6 as it is in the bracket. Then we multiply our answer by 3.

A swimming pool has a capacity of 2,500 gallons of water. The output of a hose is 25 gallon per minute. How much time would it t

g100num [7]

Answer:

100 minutes

Solution:

We know that:

Capacity = 2,500 gallons
Hose = 25 gallons/minute

Solution:

25 gallons = 1 minute
=> 25x gallons = x minutes = 2500 gallons
=> 25x = 2500
=> x = 100 minutes

Hence, it will take 100 minutes to fill the pool.

2. Red light: Pedro drives the same route to work on Monday through Friday. His route includes one traffic light.

Nataly [62]

Answer:

So, the probability is P=0.018.

Step-by-step explanation:

We know that Pedro drives the same route to work on Monday through Friday.

We know that there is a 55% chance that the light will be red.

We get that p=55%=0.55.

We conclude that the probability of not being a red light:

q=1-p=1-0.55=0.45.

We can calculate the probability that from Monday to Friday when Pedro goes to work there will be no red light, as follows:

$P=q^5\\\\P=0.45^5\\\\P=0.018$

So, the probability is P=0.018.
