Eugene walked all the way to school at 3 mph then realized she forgot her math book (how could she?!), so she ran back at 7 mph.

Fynjy0 [20]

$\text{Answer: }1\frac{23}{40}\ miles\text{ far she live from school.}$

Explanation:

Since we have given that

Speed at which Eugene walked all the way to school = 3 mph

After realizing that she forgot her math book, she ran back

Speed at which Eugene walked back to her house = 7 mph

Let the distance between her house and her school be x

According to question,

$\frac{x}{3}+\frac{x}{7}=\frac{45}{60}\\\\\frac{7x+3x}{21}=\frac{3}{4}\\\\\frac{10x}{21}=\frac{3}{4}\\\\x=\frac{3\times 63}{4\times 10}=\frac{63}{40}=1\frac{23}{40}\ miles.$

Hence,

$1\frac{23}{40}\ miles\text{ far she live from school.}$

True or False? A circle could be circumscribed about the quadrilateral below.

SVEN [57.7K]

Answer:

The correct answer is: False

Step-by-step explanation:

If the sum of the opposite angles in a quadrilateral is 180°, then a circle can be circumscribed about the quadrilateral.

Here, $\angle B+\angle D= 110\°+90\° = 180\°$

but, $\angle A+\angle C= 70\°+90\°= 160\°$

So, a circle can't be circumscribed about the given quadrilateral.
