Julie invested 3000 in a simple interest account for 2 years. At the end of the 2 years, she had earned $75 in interest. What wa
Dahasolnce [82]

The simple interest rate was: 1.25%

Step-by-step explanation:

Simple interest is given by:

A = Prt\\Here\\A  => Interest\\P=>Principal\ Amount\\r => Rate\\t => Time\ in\ years

Given

Principal amount =$3000

Time = t = 2 years

Interest amount = A = $75

putting the values in the formula

75 = 3000 * r * 2\\75 = 6000r

Dividing both sides by 6000

\frac{6000r}{6000} = \frac{75}{6000}\\r = 0.0125\\

So,

The rate is:

0.0125 * 100 = 1.25%

Hence,

the simple interest rate was: 1.25%

The value of x varies directly with the value of y, and when x=20, y=18. What is the value of “k”, the constant of proportionali
stealth61 [152]

Answer:

In this case, y=30 and x=6, so 30=k*5<=> k=30/6=5.

Step-by-step explanation:

The constant of proportionality is the ratio between two directly proportional quantities. Two quantities are directly proportional when they increase and decrease at the same rate. The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
