Answer:
3 hours and 20 minutes
Step-by-step explanation:
Jack's rate is 1 puzzle for every 5 hours, so his rate per hour is 1/5 of a puzzle per hour.
We need to find the rate of his brother so here is our equation,
1/5 + 1/x = 1/2
1/2 - 1/5 =1/x
3/10 = 1/x
3/ 3x = 3/10
3x=10
x= 3 and 1/3 hours
3 hours and 20 minutes
Answer:
[2(x+2)] + [2(2x-3)]
Step-by-step explanation:
perimeter is all sides added together. This expression multiplies both sides by 2 in order to represent the other 2 sides not notated in the picture.
Choosing the first tile:
At first, there are 7 tiles.
You are interested in choosing a 5. There is only one tile with a 5.
p(5) = 1/7
Choosing the second tile:
After the 5 has been taken, now there are 6 tiles left.
Only one tile has the number 6.
p(6) = 1/6
The overall probability of choosing a 6 after a 5 is the product of the individual probabilities:
p( 5 then 6) = 1/7 * 1/6 = 1/42
Answer: The probability of choosing a 5 and then a 6 is 1/42

Percentage of milk PM
Liters of milk LM
Liters of water W
Total number of liters TL
W/100*PM = LM
W+LM =TL
Proof
1 liter / 100 = 10 milliliters
10 ml * 20 = 200 milliliters
200 ml + 1000 ml = 1200 ml
1.2 liters is the total amount of liters.
