Answer:
17
Step-by-step explanation:
24/t + t^2
Let t=3
24/3 + 3^2
8 + 9
17
Answer:
see explanation
Step-by-step explanation:
given that r varies jointly with x and y then the equation relating them is
r = kxy ← k is the constant of variation
To find k use the condition r = 15 when x = 3 and y = 4
k = = = 1.25
r = 1.25xy ← equation of variation
When x = 16 and y = 1.25, then
r = 1.25 × 16 × 1.25 = 25
Answer:
You just multiply by 5. the 1st one will be 15.
1:15
2:35
3:100
4:2.5
5a:1 to 6 or 1:6
5b: I have no idea what this one is sorry.
