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

3. In the diagram of circle 0, two tangents have been drawn from exterior point P to the circle at points A and B. (a) If mAB =1

Maru [420]

Answer:

Step-by-step explanation:

Given:

mAB =105

The minor arc given mAB is 105. Subtract that from 360 to get the measure of the major arc mACB

<=> mACB = 360 - 105 = 255

As we know, the measure of an angle formed by two tangents intersesting outside the circle can be found by one haft of the difference between the mearsure of two intercepted arcs

=> the measure of ∠P is:

= (mACB - mAB)/ 2

= (255 - 105)/2

= 75
