JulijaS [17]

Answer: The loan have been $2500 originally.

Step-by-step explanation:

Since we have given that

Interest = $750

Rate of interest = 3%

Number of year = 1

Let P be the principal amount .

So, According to question, we get that

$750=\dfrac{P\times R\times T}{100}\\\\750=\dfrac{P\times 3\times 1}{100}\\\\\dfrac{750\times 100}{3}=P\\\\$2500=P$

Hence, the loan have been $2500 originally.

Suppose q is directly proportional to the square root of h and inversely proportional to the cube of j, and q=24 when h=16 and j

Afina-wow [57]

9514 1404 393

Answer:

q = 768

Step-by-step explanation:

The proportionality relation is given as ...

q = k(√h)/j³

Then ...

k = q·j³/√h = 24·2³/√16 = 48

For the given values, q is ...

q = 48·(√4)/(1/2)³ = 48·2·8

q = 768
