If y is inversely proportional to 1/roots then:

Y= k/root x

Find the value of the constant k

When y=7 and x=64

7=k/8
k= 56 (7x8)

When y=8

8=k/root x

Root x = k/8 since we know k = 56

Root x= 56/8

Square both sides

x=49

andrey2020 [161]

Answer:

$80

Step-by-step explanation:

From the question, we are given The simple interest formula as I = Prt,

where l = simple interest on an amount= $40

t= years=5years

at a rate r= 10%

The rate= 10/100= 0.1

Then since we are looking for P, we can make P subject of formula from this expression;

I = Prt

P=I/rt

P= 40/(0.1 ×5)

P= 40/0.5

P= 80

therefore, the amount of money p that is needed is $80
