Answer:
He needs to buy 6 and 3/4 more pints.
Step-by-step explanation:
In order to find this, we first need to find out how much he has used. To do this, add together the two fractions of the whole that he has used.
2/5 + 3/10
4/10 + 3/10 = 7/10
Since he has used 7/10 of it already, we can multiply that by the original amount to find how much is gone.
7/10 * 20 = 14
So with 14 pints having been used, we know there is 6 pints left. To find how many more he needs to buy, subtract 6 from the amount he needs for the next painting.
12 and 3/4 - 6 = 6 and 3/4
Yes she is correct it can be expressed as an fraction
Answer:
49
Step-by-step explanation:
1. Calculate the constant of proportionality
Q = k/p²
k = Qp² Multiplied each side by p²
= 36 × 7²
= 36 × 49
= 1764
2. Calculate the new value of Q
Q = 1764/p²
= 1764/36
Q = 49
