9514 1404 393

Answer:

  12.6 rad/s

Step-by-step explanation:

1080 degrees in 1.5 seconds is an angular rate of ...

  (1080°)/(1.5 s) = 720 °/s

There are π radians in each 180°, so this angular speed is ...

  720 °/s = 4×180 °/s = 4×π rad/s ≈ 12.6 rad/s

Sasha's average angular speed is 12.6 rad/s.

Point L is on line segment KM. Given LM=11 and KL=4, determine the length KM.
Scorpion4ik [409]

Hey there! I'm happy to help.

Let's think of the line segment KM as a road. It starts at point K and ends at M. You start driving from point K and after 4 miles, you have reached point L. The segment KL is equal to 4 because the distance between K and L is 4.

From point L to point M, you drive 11 miles. You are now at the end of the road. We want to find out how long the road is.

From point K to point L, you drove for 4 miles.

Then, from L to M, you drove 11.

We combine these...

11+4=15

The length of KM is 15.

Have a wonderful day! :D

An average person's heart beats about 103,630 times a day. Write and solve an equation to find about how many times the average
scZoUnD [109]
If an average persons heart beats at 103,630 times a day, and a day equals 24 hours, along with the fact that a minute consists of 60 minutes our equations can be:

103,630/(24*60)

To solve the equation we would first start with 24*60 which equals 1440. Then divide 103,630 by that number. Which would equal 71 time per minute.

Which factor pair of -24 adds to give you 10 ??
ankoles [38]

Answer:

-2 and 12

Step-by-step explanation:

It can't be 6 and -4 because 6-4=2

It can't also be -3 and 8 because -3+8=5

It can't be 1 and -24 because 1-24=-23

It can't be 2 and -12 because 2-12=-10

It can't also be -1 and 24 because -1+24=23

It can only be -2 and 12 because -2 + 12= 10
