ANSWER
y varies inversely as x exponent 4.
EXPLANATION
The inverse variation equation is given as:
We can see that there is an inverse relation between the quantity y and x.
If the it were , we say y varies inversely as the square of x.
Hence for the given relation,the precise definition is that, y varies inversely as x exponent 4.
Answer: 9 rolls of cloth A and 44 roles of cloth B
Step-by-step explanation:
Let x represent the number of rolls of cloth A that can be dyed and dried.
Let y represent the number of rolls of cloth B that can be dyed and dried.
A roll of Cloth A requires 50 minutes of dyeing time. A roll of Cloth B requires 55 minutes of dyeing time. The production division allocates 2280 minutes of dyeing time. This means that
50x + 55y = 2880- - - - - - - -1
A roll of Cloth A requires 45 minutes of drying time. A roll of Cloth B requires 30 minutes of drying time. The production division allocates 1740 minutes of drying time. This means that
45x + 30y = 1740- - - - - - - -2
Multiplying equation 1 by 45 and equation 2 by 50, it becomes
2250x + 2475y = 129600
2250x + 1500y = 87000
Subtracting, it becomes
975y = 42600
y = 42600/975
y = 44
Substituting y = 44 into equation 1, it becomes
50x + 55 × 44 = 2880
50x + 2420 = 2880
50x = 2880 - 2420
50x = 460
x = 460/50
x = 9
Answer:
I think 38%
Step-by-step explanation:
Part A: B (t) = 0.93t (975) and T (t) = 350 - 7t
