Answer:
x = 
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = - 6 when x = 2, then
- 6 = 2k ( divide both sides by 2 )
- 3 = k
y = - 3x ← equation of variation
When y = - 22, then
- 22 = - 3x ( divide both sides by - 3 )
x = 
=
Since you already know that the first 50 meters took 1min you can subtract
400meters-50meters=350meters
350meters÷50meters=7minutes
It increases at 12 sec./min for 7mins
1.12,1.24,1.36,1.48,2.00,2.12,2.24= 11.56+1.00=12.56min
Answer:
5
Step-by-step explanation:
10,000,000÷2,000,000=5
(1x10^7)÷ (2x10^6) = 5
Answer:
The unit of measure used in the study is "inches"
Answer:
p=117.25
Step-by-step explanation:
441/4=110.25
110.25+7=117.25
