- A box contains only blue and black glass
beads. The probability of randomly choosing a
blue bead out of the box is 3 times the
probability of randomly choosing a black bead
out of the box. If there are 12 beads in the box,
how many are blue?
A. 3
B. 4
C. 6
D. 9

Answers

Answer 1

Answer:

D.

Explanation:

Blue beads are 3 times more likely to be pulled. Therefore, since there are 12 beads in total the ratio which would fit the ratio of probability to pull blue beads compared to black beads would be 9/12 leaving 3/12 probability to pull a black bead. if you simplify the fractions you get 3/4 and 1/4 where 1/4 (the probability to pull a black bead) is three times less than the probability to pull a blue bead.

The Escobar family went on a car trip. They drove 100 miles on country roads and 240 miles on the highway. They drove 50% faster on the highway than on the country roads. Let r represent their rate on country roads in miles per hour. a. Write and simplify an expression that represents the number of hours it took the Escobar family to complete their trip in terms of r. (Hint: 50% faster means 150% of the original rate.) b. Find their total travel time if they drove the posted speed limit.

Answers

Answer: Hey I'm sorry I didn't get to answer your question it's just that I need the points because I don't have enough to get help with my question. I hope you get the answer that you need for you question. Good Luck :)..

Explanation:

The expression that represents the number of hours it took the Escobar family to complete their trip in terms of r is 260/r

The expression for the total time of travel?

Let r represent their rate on country road and R represent their rate on highway.

So, we have:

R = (100% + 50%) * r

Evaluate

R = 1.5r

Rate is calculated using:

Rate = Distance/Time

So, we have:

r = 100/t and R = 240/T

Make T and t the subject

t = 100/r and T = 240/R

The total time of travel is:

Total = t + T

So, we have:

Total = 100/r + 240/R

Substitute R = 1.5r

Total = 100/r + 240/1.5r

Simplify

Total = 100/r + 160/r

Evaluate the sum

Total = 260/r

The total time of travel

The speed limit is 40mph

This means that:

r = 40

In (a), we have:

Total = 260/r

Substitute 40 for r

Total = 260/40

Evaluate

Total = 6.5

Hence, their total time of travel is 6.5hours

Answers

Answer:

c=11

Explanation:

[tex]n - \sqrt{c + 5} = 1[/tex]

[tex]5 - \sqrt{c + 5} = 1[/tex]

Add sqr root of c+5 to both sides

[tex]5 = 1 + \sqrt{c + 5} [/tex]

[tex]4 = \sqrt{c + 5} [/tex]

[tex]16 = c + 5[/tex]

Answer:

c is 11

Explanation:

[tex]n - \sqrt{c + 5 } = 1 \\ 5 - \sqrt{c + 5} = 1 \\ [/tex]

make -√c+5 the subject:

[tex] - \sqrt{c + 5} = 1 - 5 \\ - \sqrt{c + 5} = - 4[/tex]

divide through out by -1 :

[tex] \frac{ - \sqrt{c + 5} }{ - 1} = \frac{ - 4}{ - 1} \\ \\ \sqrt{c + 5} = 4[/tex]

square both sides;

Truck A leaves a loading dock and averages 40 miles
per hour until it makes a stop in Dover County. Truck B
leaves the same loading dock two hours after Truck A and
averages 60 miles per hour until it makes a stop in Dover
County as well. If both trucks arrive in Dover County at
the same time, how many miles is Dover County from the
loading dock?

Answers

Answer: 240 miles

Explanation: Since Truck A moves 40 miles in one hour, we can say that the truck traveled 40 miles after 1 hour, 80 miles after 2 hours, 120 miles after 3 hours, 160 miles after 4 hours, 200 miles after 5 hours, and 240 miles after 6 hours.

Now since Truck B moves 60 miles in one hour, it moved 60 miles in one hour, 120 miles in 2 hours, 180 miles in 3 hours, and 240 miles in 4 hours.

So when the question tells you that both trucks arrived at the same time, you can find the answer by looking for the distance where the two trucks met. So in this case, it would be 240 miles because Truck A took 6 hours to get to 240 miles and Truck B took 4 hours to get to 240 miles and since Truck A moved 2 hours ahead of Truck B, the answer would be correct.

Therefore, Dover county is 240 miles away from the loading dock.
