The denominator of a fractional exponent represents the degree of root.

For example

$x^{\frac{1}{3}} = \sqrt[3]{x}\\x^{\frac{1}{4}} = \sqrt[4]{x}\\x^{\frac{1}{5}} = \sqrt[5]{x}$

Find the area. The figure is not drawn to scale

poizon [28]

Answer:

96 square inches.

Step-by-step explanation:

From given picture we see that

BC=8 in

AD=10 in

Given that

AD=AB

Then AB=10 in

Apply Pythagorean theorem in triangle ABC to find AC

$(hypotenuse)^2=(base)^2+(perpendicular)^2$

$(AB)^2=(BC)^2+(AC)^2$

$(10)^2=(8)^2+(AC)^2$

$100=64+(AC)^2$

$100-64=(AC)^2$

$36=(AC)^2$

take square root

$6=AC$

Then area of triangle ABC $=\frac{1}{2}\left(base\right)\left(altitude\right)$

$=\frac{1}{2}\left(8\right)\left(6\right)=24$

There are total 4 congruent triangles.

Then total area of the given figure = 4(24)=96 square inches.

dolphi86 [110]

Answer:

Sessions needed= 12

Step-by-step explanation:

Giving the following information:

Total hours= 12 hours

Practice= 3/4= 0.75 of an hour

Already practiced= 3 hours

<u>First, we need to determine how many minutes does she practice each session:</u>

Minutes per session= 0.75*60= 45 minutes

<u>Now, we divide the total practice in minutes required for the minutes per session:</u>

Sessions needed= (9*60) / 45

Sessions needed= 12
