Bob drove 30 and one third miles towards his house in one third an hour. About how long will the entire 100 mile trip take at th
Gemiola [76]

It would take 1\frac{9}{91} hour to complete the entire trip.

Step-by-step explanation:

Given,

Distance covered = 30\frac{1}{3} = \frac{91}{3} miles

Time taken =\frac{1}{3} hour

We know that;

Distance = Speed * Time

\frac{91}{3} = Speed*\frac{1}{3}

Multiplying both sides by 3

3*\frac{91}{3} = Speed*\frac{1}{3}*3

91 = Speed

Bob was driving at 91 miles per hour.

Now,

Distance to cover = 100 miles

Time required = x

Distance = Speed * Time

100=91x\\91x=100

Dividing both sides by 91

\frac{91x}{91}=\frac{100}{91}\\x=1\frac{9}{91}

It would take 1\frac{9}{91} hour to complete the entire trip.

Sauron [17]

Answer:

\dfrac{4}{27}

Step-by-step explanation:

A bag contains 8 blue marbles 6 red marbles and 4 green marbles, 8 + 6 + 4 = 18 marbles in total.

The probability of selecting a blue marble is

P(\text{blue marble})=\dfrac{\text{Number of blue marbles}}{\text{Total number of marbles}}=\dfrac{8}{18}=\dfrac{4}{9}

Then the blue marble was replaced in the bag.

The probability of selecting a red marble is

P(\text{red marble})=\dfrac{\text{Number of red marbles}}{\text{Total number of marbles}}=\dfrac{6}{18}=\dfrac{1}{3}

The probability of selecting a blue marble replaced it in the bag and then selecting a red marble is

P=\dfrac{4}{9}\cdot \dfrac{1}{3}=\dfrac{4}{27}
