Answer:

Length of an arc is given by:

l = r \theta          ......[1]

where,

r is the radius of the circle

\theta is the angle in radian.

As per the statement:

A circle has a radius of 9 cm.

⇒r =9 cm

It is also given that: intercepted arc length is 7.2 cm

Substitute the given values in [1] we have;

7.2 = 9 \cdot \theta

Divide both sides by 9 we get;

0.8 = \theta

Therefore, the measure in radians for the central angle is, 0.8

nadezda [96]
If the width is 28 inches, then divide that by 4 and you get 7. You multiply that by 5 to get the length. That would be 35. Just to check, you know that the width 28 and length 35 are in ratio 4:5 if you divide by 7. The perimeter would be 2(35+28)=63*2=126. So the perimeter is 126. The area would be 35*28 which is 980. To sum up, the answers are as follows.

Length: 35 in
Perimeter: 126 in
Area: 980 inches squared.

One sign lights up every 10 seconds. One sign lights up every 12 seconds. If they have just lit up at the same time, how many se
andrew11 [14]

Answer:

It will take 60 seconds for the signs to light up at the same time again.

Step-by-step explanation:

Given:

One sign lights up every 10 seconds

One sign lights up every 12 seconds

They have just lit up at the same time.

To find in how many seconds will it take for the signs to light up at the same time again.

Solution:

In order to find the time in seconds will it take for the signs to light up at the same time again, we need to find the least common multiple of the the times for which the given signs light up.

The numbers are 10 and 12.

To find the LCM, we will list the multiples of each and check the least common multiple.

The multiples of 10 and 12 are :

10\rightarrow 10,20,30,40,50,60,70

12\rightarrow 12,24,36,48,60

thus, we can see that 60 is the least common multiple.

Thus, the signs will light up at the same time time after every 60 seconds.
