Answer:
1) the constant of variation is 1/6
2) b=80 when A=10
3)the value of k is 40
4) x=0.032 when y = 10
Step-by-step explanation:
1)m varies directly as y
k is the constant of variation
We are given that m is 6 when y is 36
Hence the constant of variation is 1/6
2)A varies directly as b.
k is the constant of variation
We are given that A = 3 when b = 24
Substitute A=10
80=b
So, b=80 when A=10
3)y varies inversely with x
k is the constant of variation
We are given that y = 5 when x = 8
So, the value of k is 40
4)y varies inversely with x
k is the constant of variation
We are given that k=0.32
Substitute y = 10
So, x=0.032 when y = 10
Answer:
Hello,
Step-by-step explanation:
Let say t the time the hose is left running
235 ≤ t < 245 (in min)
Let say d the amount of water coming out of the hose each minute
2.05 ≤ d < 2.15 (why d : débit in french)
235*2.05 ≤ t*d < 245*2.15
<u>481.75 ≤ t*d < 526.75 </u> (litres)
What were the other choices??
