Luba_88 [7]

Answer:

Flying squirrel have to glide is for 9.8 meters approximately.

Step-by-step explanation:

Here we can use Pythagoras theorem.

Height is 9 , base is 4.

We need to find the hypotenuse measure.

So, let's use Pythagoras theorem $a^{2} +b^{2}= c^{2}$

Plug in a as 9 and b 4.

$9^{2} +4^{2}=c^{2}$

Simplify the left side of the equation

$81+16=c^{2}$

$97=c^{2}$

Take square root on both sides.

c=9.8 meters.

Lady bird [3.3K]

Answer:

⇒ $\frac{21}{2}$

⇒ $10 \frac{1}{2}$

Step-by-step explanation:

3 3/4 = 15/4

2 4/5 = 14/5

⇒ $(\frac{15}{4} *\frac{5}{5} )(\frac{14}{5} *\frac{4}{4} )$

⇒ $\frac{75}{20} *\frac{56}{20}$

⇒ $\frac{4200}{400}$

⇒ $\frac{21}{2}$

⇒ $10 \frac{1}{2}$
