In a group of 28 students, 6 study both Art and Biology.
Helen [10]

Answer:

3/13

Step-by-step explanation:

There are 28 students.  1 studies biology but not art.  1 studies neither subject.  Therefore, there are 26 students who study art.

Of the 26 students who study art, 6 also study biology.  So the probability is 6/26, which reduces to 3/13.

Need help,please and thank you
muminat

If the two angles form a linear pair, the sum of the angles is 180 degrees.

If the small angle is one-third of the other, then the total is 1+1/3=4/3 of the larger angle.

By proportion,

L+L/3=4L/3=180

L=180*3/4=135 degrees

Smaller angle = L/3=45 degrees

Check: L+L/3=135+45=180 degrees, ok

Can someone help will give brainlist
max2010maxim [7]

Answer:

Option B

Step-by-step explanation:

Time taken by Nathan to completethe task = 4 hours

\text{Work done by Nathan in 1 hour = $\dfrac{x}{4}$}

Time taken by Elijah to complete the task = 3 hours

\sf \text{Work done by Elijah in 1 hour=$\dfrac{x}{3}$}

They work together to complete the work

\text{Work done by both in 1 hour = $ \dfrac{x}{4}+\dfrac{x}{3}$}

                                              \sf =\dfrac{x*3}{4*3}+\dfrac{x*4}{3*4}\\\\=\dfrac{3x}{12}+\dfrac{4x}{12}\\\\=\dfrac{7x}{12}

\text{Time taken by both= x $\div$ $\dfrac{7x}{12}$}

                              \sf = x * \dfrac{12}{7x}\\\\     = \dfrac{12}{7}

                              ≈ 1.7 hours
