The value of z if x = 36 and y = 6 is 42
<h3>Direct and inverse variation</h3>
Suppose that y varies directly with x and inversely with z, hence the required expression will be:
y = kx/z
If y = 4 when x = 8 and z = 14 then;
4 = k(8)/14
8k = 56
k = 7
To find z when x = 36 and y = 6, we will have:
6 = 7(36)/z
1 = 7(6)/z
z = 42
Hence the value of z if x = 36 and y = 6 is 42

Answer:
Investment with interest rate 0.1872 is better
Step-by-step explanation:
Given as :
George investment principal = $20,000
The Rate of interest (R1) = 18
% =
%
I.e R1 = 18.67 %
Again The The Rate of interest (R2) = 0.1872 = 18.72 %
Let the time period for both rate of interest = 1 years
Now from compound interest method
Amount = Principal ×
Or, A 1 = $ 20 , 000 ×
Or, A 1 = $ 20 ,000 × 1.1867
∴ A 1 = $ 23,734
And A 2 = $ 20 , 000 ×
Or, A 2 = $ 20 ,000 × 1.1872
∴ A 2 = $ 23,744
Hence From the calculation of both amount it is clear that , investment with interest rate 0.1872 is better . Answer
The first 5 multiples of 15 are: 0, 15, 30, 45, 60
Answer:
p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8
p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
Step-by-step explanation:
Price, p of weight of a toughurt serving :
p(w) - - - - - - p = 0.5w ; for 0 < w ≤ 8
p(w) - - - - - - p = 4 ; for w < 8 and w ≤ 12
