John had 2⁄3 of his homework complete, Sarah had 5⁄10, Alex 7⁄8, and Michelle 1⁄2. Who completed the most of the homework assign
yuradex [85]
Hey there!

So, when finding who completed more, we would want to find the lowest denominator, but also, we would have to compare it with the numerator.

John: He completed 2/3, which is basically almost done.

Sarah: She only completed (half) of her homework.

Alex: He only did 7/8

Michelle: He/she only did 1/2, which is only half.

So, from looking at these fractions above, Michelle and Sarah are out.

We would just have to determine, which is finished more, John or Alex.

John had 2/3 & Alex 7/8

So, by comparing them both, 7/8 would be greater because the smaller the denominator is, and the closer that the numerator is to the denominator, this would mean that the homework is almost finished.

Your correct answer is Alex, he has completed more.

Hope this helps you!

Please help asap!<br><br>the problem is in the picture

Given:

AB=6\ BC=r,\ CD=r,\ AD=12.

To find:

The value of r.

Solution:

We have,

AB=6\ BC=r,\ CD=r,\ AD=12.

We know that the radius is perpendicular to the tangent at the point of tangency

AD is the tangent and CD is the radius. So, CD is perpendicular to AD at point D, i.e., m\angle D=90^\circ.

Using Pythagoras theorem, we get

AC^2=AD^2+CD^2

(6+r)^2=12^2+r^2

36+12r+r^2=144+r^2

12r=144+r^2-36-r^2

On further simplification, we get

12r=108

r=\dfrac{108}{12}

r=9

Therefore, the value of r is 9.
