The Perimeter or a regular pentagon is 41.5cm. Write and solve an equation to determine the length of each side of the pentagon

olchik [2.2K]

Answer:

8.3 cm

Step-by-step explanation:

So a pentagon has 5 equal sides, and the perimeter is the distance around a figure. Because we know the perimeter is 41.5 centimeters, we just divide that number by 5.

Perimeter (P) = s+s+s+s+s (sides)

P: 41.5 cm ÷ 5 =

8.3 cm

We know this is correct because:

8.3 + 8.3 + 8.3 + 8.3 + 8.3 = 41.5

Hope this helps!

the equation y= -16t^2+120 can be used to represent the fridge height above the ground where ti represents time in seconds after

dimulka [17.4K]

Answer:

<em>It takes the apple 2.738... seconds to hit the ground.</em>

Step-by-step explanation:

The given equation is: $y= -16t^2 +120$

Here, $y$ represents the fridge height of the apple above the ground after $t$ seconds.

<u>When the apple hit the ground, then it's height will become 0</u>.

So, plugging $y=0$ into the above equation, we will get.......

$0=-16t^2+120\\ \\ 16t^2= 120\\ \\ t^2= \frac{120}{16}=7.5\\ \\ t=\sqrt{7.5}=2.738...$

Thus, it takes the apple 2.738... seconds to hit the ground.

If RT is a diameter of Q, Find m A.88°<br> B.89°<br> C.92°<br> D.101°

kumpel [21]

Answer:

A.88°

Step-by-step explanation:

Given,

RT is the diameter of the circle with center Q.

We have to find the measure of ∠RQS.

Solution,

$m\angle RQS=7x+18\ \ \ and\\m\angle TQS=9x+2$

Since RT is the diameter. That is it makes a straight angle at the center Q.

And measure of straight angle is 180°.

So we can say that ∠RQS and ∠SQT makes a straight angle.

$\therefore \angle RQS+\angle SQT=180\°$

Now substituting the given values, we get;

$(7x+18)+(9x+2)=180\°\\\\7x+9x+20=180\°\\\\16x=180-20=160\°\\\\x=\frac{160}{16}=10\°$

We get the value of 'x'.

By substituting the value of x, we can find the measure of ∠RQS.

$m\angle RQS=7x+18=7\times10+18=70+18=88\°$

$m\angle TQS=9x+2=9\times10+2=90+2=92\°$

Hence the measure of ∠RQS is 88°.
