Using the least common denominator rename 3/5 and 11/20?

irina1246 [14]

Answer:

12/20 and 11/20.

Step-by-step explanation:

The least common denominator between 3/5 and 11/20 is 20.

For the first equation, we multiple the numerator and denominator by 4 and we get 12/20.

The second equation already has a denominator of 11/20 so we can leave it as is.

Answer: The gravity's constant value is $9.8 m/sec^2$ .

Explanation:

The given function shows the distance from the ground (in meters) at time t (in sec).

$d(t)=-4.9t^2+50$

First derivative of displacement is velocity and the second derivative of displacement is acceleration.

Differentiate the given equation with respect to t.

$v(t)=d'(t)=-9.8t+0$

Differentiate the above equation with respect to t.

$a(t)=v'(t)=d''(t)=-9.8$

It is given that gravity is the only acceleration affecting the object and the negative sign shows the downward direction of the object.

Therefore, the gravity's constant value is $9.8 m/sec^2$ .

Question five What is the perimeter? Use 3.14 for pi. Please Show Work! I Will Mark As Brainlest!!

levacccp [35]

Answer:

73.81

Step-by-step explanation:

You know that the formula for circumeference is 2(pi)r.

2x3.14x11=69.08;

However, a part of the circle is cut off, leaving 3/4 of it.

3/4x69.08=51.81.

However, you add the 11+11 to it because of the slice.

22+51.81=73.81

The radius of a circle is 3 cm. Find it's area in terms of pi. 28.27 cm2 is wrong

sladkih [1.3K]

Answer:

9 $\pi$

Step-by-step explanation:

The reason why that is wrong is because it says in terms o pi which means you do NOT multiply pi by the radius squared.

EQUATION FOR AREA OF A CIRCLE: $\pi r^{2}$

When you put it all together you get: $\pi * 3^{2}$ which equals $9\pi$

DO NOT MULTIPLY 9 AND PI. IT'S JUST 9 $\pi$

hope this helped :)
