Answer:

l = 2.25 cm

Step-by-step explanation:

given l is inversely proportional to w² then the equation relating them is

l = $\frac{k}{w^2}$ ← k is the constant of proportion

(i)

to find k use the condition w = 1.5 , l = 16 , then

16 = $\frac{k}{1.5^2}$ = $\frac{k}{2.25}$ ( multiply both sides by 2.25 )

36 = k

l = $\frac{36}{w^2}$ ← equation of proportion

(ii)

when w = 4 , then

l = $\frac{36}{4^2}$ = $\frac{36}{16}$ = 2.25 cm

What expressions equal to 1 forth of 52

Klio2033 [76]

Remember that x/4 and 1/4*x is the same thing.

1/4*52 is therefore the same as 52/4. Fractions represent division, so 52 divided by 4 is also correct.
0.25*x is the same as 1/4*x because 1/4=0.25
4% of 52 is incorrect because the decimal form of 4% is 0.04, which is not the same as 0.25

Final answer: B
