You can invest $200 at 8% for 3 years. Find the simple interest.
Ira Lisetskai [31]

Answer:

$48

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 8%/100 = 0.08 per year,

then, solving our equation

I = 200 × 0.08 × 3 = 48

I = $ 48.00

The simple interest accumulated

on a principal of $ 200.00

at a rate of 8% per year

for 3 years is $ 48.00.

Write an equation of the line that passes through (18, 2) and is parallel to the line 3y - x = -12
GarryVolchara [31]
First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b 
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line

10, 18, 4, 15,3,21, x
alukav5142 [94]
You have to orginize them from smallest to largest, 'x' is the median so I put it in the middle:
3, 4, 10, x,15, 18, 21

That means 11-14 could be x.
