10 marbles in each bag...2/10 are striped...2/10(10) = 20/10 = 2 are striped.So in every bag of 10 marbles, 2 are striped. So if there is 3 bags of marbles....then (3 x 2) = 6 are striped. <== he needs 6 striped
Well let's see what floor each one lands on and figure out which one is higher.
Something to note:
down = subtracting
up = adding
if something says it's doing something more than once, add it the number of times it's doing that thing. (You can also multiply it by that number but the adding way is a bit easier to understand and explain)
<u>Elevator 1:</u>
6 + 7 + 7 - 10 = 10
<u>Elevator 2:</u>
20 - 5 - 5 - 5 + 12 = 17
Elevator 2 ends on a higher floor (reasoning above)
Answer:-
-93
Step-by-step explanation:
You keep on subtracting 98 from it.
Answer:
1/5
Step-by-step explanation:
The stick has a length of 5 units
The stick is broken at two points chosen at random
First break: the probability that you get a piece that is 1 unit or longer than 1 units= 1/5.
Second break, the probability that you get a piece that is 1 unit or longer than 1 units is 1/5.
Therefore,
The total probability =probability of first break * probability of second break * original stick unit
=1/5 * 1/5 * 5
= 1/25 *5
=5/25
=1/5
243 liters represents 7/10 - 1/4 of the water.
v=243 / (7/10 - 1/4) = 243 / (14/20-5/20) = 243(20)/9 = 540 liters.
Answer: 540 liters
Check:
(7/10)(540) = 7(54) = 378
(1/4)540 = 135
difference = 378 - 135 = 243 good
