Answer:
four is the right answer i think
Answer:
5 minutes.
Step-by-step explanation:
We have been given that the number of minutes needed to drain a bathtub, m, varies inversely as the rate of draining, r.
We know that two inversely proportional quantities are in form , where y is inversely proportional with x and k is constant of proportionality.
Upon substituting our given variables in inversely proportion, we will get:
Let us find constant of proportionality using our given information.
So our required equation would be .
Now, we will substitute in our equation to solve for time.
Therefore, it will take 5 minutes to drain the bathtub at a rate of 32 liters per minute.
Angle is 90 degrees, so five-thirds of a right angle is 90*5/3=450/3=150 degrees.
Answer:
80
Step-by-step explanation:
180-100=80
The weight of 9 bags is 5.4 blocks
<em><u>Solution:</u></em>
Given that,
5 bags weigh the same as 3 blocks
We have to find how many blocks will 9 bags weigh
Let "x" be the weight of 9 bags
Then,
5 bags weigh the same as 3 blocks
9 bags weight the same as "x" blocks
From proportion we can say,
5 : 3 : : 9 : x
Therefore,
Thus the weight of 9 bags is 5.4 blocks
