Answer:

1 km

Step-by-step explanation:

if the distance between M and K is 2 km and the store is situated exactly in the middle between M and K then the distance to the store from either M or K is half the distance between the two points M and K and therefore 1 km

When a watch is sold at ksh 126 aloss of x percent is made . If the same ksh 126, a loss of x percent is made . If the same watc

Nitella [24]

Answer:

ksh 140

Step-by-step explanation:

When a watch is sold for ksh 126 a loss of x% is made, that is( 100 - x)%

Hence, the loss amount = (126 X 100)/(100 - x)

When the same watch is sold for ksh 154 a profit of x% is made, that is (100 + x)%

Hence, the profit amout = (154 X 100)/(100 + x)

Therefore, (126 X 100)/(100 - x) = (154 X 100)/(100 + x)

12600(100 + x) = 15400(100 - x)

1260000 + 12600x = 1540000 - 15400x

28000x = 280000

x = 10%

In that case for a watch sold for ksh 126 a loss 10% is made, that is( 100 - 10)%

Hence, loss amount = (126 X 100)/90 = ksh 140

∴ the buying price is ksh 140

In one day Sasha got 1 hour of sleep for every 3 hours she was awake if there are 24 hours in a day how many hours of sleep did

Gre4nikov [31]

Answer:

Hours slept = 6 hours

Hours awake = 18 hours

Step-by-step explanation:

Sasha got 1 hour of sleep for every 3 hours she was awake.

So,

<u>This means:</u>

Slept : Awake = 1 : 3

Total hours in a day = 24 hours

Hours slept = 1x and hours awake = 3x

<u>Hence,</u>

1x + 3x = 24 hours

4x = 24

Divide both sides by 4

x = 24 / 4

x = 6

Hours slept = 1(6) = 6 hours

Hours awake = 3(6) = 18 hours

$\rule[225]{225}{2}$

Hope this helped!
