if a sprinter runs are distance of hundred metres in 9.83 seconds calculate the speed in kilometre per hour​
My name is Ann [436]

Answer:

98.3 seconds

Step-by-step explanation:

If you use stoichometry you can convert your units

9.83 seconds

over 100 meters    a kilometer is 1000 meters so

9.83/100 *10 because what you do to denominator needs to happen to numerator

98.3 seconds

over 1 kilometer

it take the sprinter 98.3 seconds to run a kilometer and one way to check is well a kilo is a longer distance so logically the time it takes them has to be higher cause they cannot run a kilo faster than they run 1/10 of it

6/54-x = 5/x <br>x=____<br><br><br><br>​
amm1812

Answer:

<u>x=−44/9</u>

Step-by-step explanation:

6/54−x=5/xx

Simplifies to:

−x+1/9=5

Let's solve your equation step-by-step.

−x+1/9=5

Step 1: Subtract 1/9 from both sides.

−x+1/9−1/9=5−1/9

−x=44/9

Step 2: Divide both sides by -1.

−x/−1=44/9/−1

x=−44/9

Olive is allowed to bring one friend on a trip with her.
san4es73 [151]

Answer:

Process of elimination

Step-by-step explanation:

If Olive wants to choose a friend while not playing favorites, while also not being random, she has to eliminate the ones she knows she will NOT take on the trip. She can choose this by selecting the one she knows that will be best on the trip with her, depending on the situation.

Or, if Olive only has one friend, then it wouldn't be surprising that she would take that one friend on the trip, since she has no one else to choose. This way, it is not playing favorites, nor is it random. Hope this helps you!
