I believe the answer is 0.9 because a significant figure is a similar difference
Answer:
y = 46
Step-by-step explanation:
Given y varies inversely as x then the equation relating them is
y =
← k is the constant of variation
To find k use the condition y = 23 when x = 8 , then
23 =
( multiply both sides by 8 )
184 = k
y =
← equation of variation
When x = 4 , then
y =
= 46
It should be 75×3=115 then 115×4=160 so 160 should be the answer!
Answer:
B
Step-by-step explanation:
7^2+x^2=18^2
49+x^2=324
x^2=275
x=square root of 275
x=16.83
Your closest answer is 16.6
