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:
<h2>you can fill 40 (150ml) glasses with 5 bottles of soft drinks</h2>
Basic fact:
<em>there are 1000 ml in a litre</em>
Step-by-step explanation:
let us do
5 x 1.2
= 6
now let's turn 6 litres in ml
6 x 1000
=6000
now we need to do
6000/150
instead of doing such big numbers, lets do
600/15
=40
Answer:
Step-by-step explanation:
<u>To find the solution of the inequality given, we must isolate the variable</u>.
<u>Simplifying the RHS:</u>
Hence, the variable 'y' must be below than 0 to make this statement true.
