The millers drove 150 miles in 3 hours at what rate how long will it take them to drive 400 miles

2 answers:

8 0

Rate = (150 miles)/(3 hrs) = 50 mph

so . . .

(50 mph)*(time) = 400 miles

*divide both sides by 50 mph

time = (400 miles)/(50 mph) = 8 hrs

time = 8 hrs

150 divided by 3 = 50 miles per hour. Therefor it would take them 8 hours to drive 400 miles. :)

If two dice are thrown whats si the probability that they will add to 9?A2/36B3/36C3/36D4/36

GuDViN [60]

Answer:

D. $\frac{4}{36}$

Step-by-step explanation:

Solution,

Two dice are thrown.

So we have to find out the total number of outcomes.

$(1,1),\ (1,2),\ (1,3),\ (1,4),\ (1,5),\ (1,6)$

$(2,1),\ (2,2),\ (2,3),\ (2,4),\ (2,5),\ (2,6)$

$(3,1),\ (3,2),\ (3,3),\ (3,4),\ (3,5),\ (3,6)$

$(4,1),\ (4,2),\ (4,3),\ (4,4),\ (4,5),\ (4,6)$

$(5,1),\ (5,2),\ (5,3),\ (5,4),\ (5,5),\ (5,6)$

$(6,1),\ (6,2),\ (6,3),\ (6,4),\ (6,5),\ (6,6)$

The total number of outcomes = $36$

We have to find out the probability of outcomes that add up to 9.

So, Possible outcomes are;

The total number of possible outcomes = $4$

Now, according to the formula of probability,

$P(E)=\frac{Total\ number\ of\ Possible\ outcomes}{Total\ Number\ of\ outcomes}$

$P(of\ add\ up\ to\ 9)=\frac{4}{36}$

Hence the correct option is D)4/36.
