Since it's a simple interest, that means yo will apply the following formula:
I=Prn Where I = Amount of interest earned, P=initial capital, r, the rate or interest
$426 = $1200 x 5 years x r interest ,Calculate r:
426 = 1200 x 5 x r===> 426 = 6000 r; divide both sides by 6000
426 / 6000 = 6000 r / 6000 ==> ==> r= 0.071 or 7.1% This is the answer
Answer:
(-1, 1)
Step-by-step explanation:
I used a graphing tool to graph the equations. When graphed, they cross at coordinate (-1, 1). Therefore, (-1, 1) is the solution.
Answer:
10.3 in
Step-by-step explanation:
a = (1/2)b*h
53 = (1/2)x * x
53 = (1/2)x²
Multiply both sides by 2
106 = x²
Take the square root of both sides
x = 10.3
Answer:
1/80
Step-by-step explanation:
-8*5*xy= -1
Sub 2 for x
-8*5*2*y= -1
-80y=-1
y=1/80
(i was kinda confused because i wasn't sure if the x was a variable or a multiplication symbol but i made it a variable) yea
