Answer:
c = 92/n
Step-by-step explanation:
The equation that describes the inversly proportional relationship is ...
y = k/x
The value of the constant of proportionality can be found from ...
xy = k . . . . . . product of values of independent and dependent variables
__
In this problem, we have c = 23 for n = 4, so the constant of proportionality is ...
k = c×n = (23)(4) = 92
The equation for the relationship is ...
c = 92/n
Answer:
You want 40% of 140 gallons to be methane,
so 60% of 140 gallons is water
methane: 0.4(140) = 56 gallons
water: 0.6(140) = 84 gallons
Step-by-step explanation:
Answer: 4/52
Step-by-step explanation:
Because thwre are 4, fives in a normal deck so the probability would be 4/52 not simplifyed
$18. You get this because you subtract 7 from 16 since that’s money he got. You get 9. Since Jack spent half his allowance money, you double the money he had left after spending it, giving you $18.
Answer:
Length = 200 m
Breadth = 175 m
Step-by-step explanation:
Perimeter of the rectangular field = Total cost ÷ rate per metre
= 12000 ÷ 16
= 750 m
Length : breadth = 8 : 7
Length = 8x
Breadth = 7x
Perimeter = 750
2*(length + breadth) = 750
2*(8x + 7x) = 750
2* 15x = 750
30x = 750
x = 750/30
x = 25
Length = 8x = 8*25 = 200 m
Breadth = 7*25 = 175 m
