5/8 people vote for blue
zhenek [66]

Answer:

The number of people vote for blue is 180.

Step-by-step explanation:

Let there are x numbers of total people.

So, \frac{5}{8} of total people vote for blue i.e. \frac{5x}{8} people vote for blue.

Now, the remaining number of people are (x - \frac{5x}{8}) = \frac{3x}{8}.

If \frac{5}{9} of the remaining people vote for green, then the number of people vote for green will be (\frac{3x}{8} \times \frac{5}{9}) = \frac{5x}{24}.

Therefore, finally the remaining number of people is (\frac{3x}{8} - \frac{5x}{24}) = \frac{x}{6} and they vote for red.

Now, \frac{x}{6} = 48 {Given}

⇒ x = 288

And the number of people vote for blue is \frac{5x}{8} = \frac{5 \times 288}{8} = 180. (Answer)

(e) The number of bees spotted in Amelie's garden can also be modeled by the function B(x) = 50√ k + 2x where x is the daily hig
Lunna [17]

Answer:

\frac{dB}{dt}=4

Step-by-step explanation:

Derivative indicates rate of change of dependent variable with respect to independent variables. It indicates the slope of a line that is tangent to the curve at the specific point.

Given:

Number of bees is modeled by the function B(x)=50\sqrt{k}+2x

The daily high temperature is increasing at a rate of 2 °F per day when  the number of bees spotted is 100.

To find:

rate of change of number of bees when 100 bees are spotted

Solution:

B(x)=50\sqrt{k}+2x

Differentiate with respect to t,

\frac{dB}{dt}=0+2(\frac{dx}{dt}) \\\frac{dB}{dt}=2(\frac{dx}{dt}) \\

Put (\frac{dx}{dt}) =2

\frac{dB}{dt}=2(2)=4

At x = 100, \frac{dB}{dt}=4

1/3+1/4 I really don’t get this so can someone please help me with this problem
Oxana [17]

Answer:

7/12

Step-by-step explanation:

You have to find a common denominator, so you would multiply 3 from the 1/3 by 4 which gets you twelve. And bc you multiplied the 3 you have to multiple the 1 so 1/3 would be 4/12. You would then multiply 4 by 3 and get 12. Then do the same to the one on top. So 1/4 would be 3/12. You then add 3 and 4 and get 7. That’s the numerator, the denominator stays 12. So it would be 7/12

Mr. Wells tells his class of 24 that when they completed the assignment, they may play online math games. At the end of class, 4
QveST [7]

Hello there! Your answer is approximately 14 students.

To solve this question, you want to start by finding 40% of 24. To do this, convert 40% into a decimal (divide by 100) and multiply by 24.

24 x 0.40 = 9.6.

But - you can't have 9.6 of a student. So, we round up to 10.

Note that the question asks how many students <em>still need to complete</em> their assignment, meaning we are looking for the ones that haven't finished. We found the amount for students that <em>have</em> finished, so subtract that from the total to see approximately how many still have to finish.

24 - 10 = 14

So, this means approximately 14 students still need to complete their assignment.

I hope I could help you, have a great rest of your day! :D
