Answer:
$150
Step-by-step explanation:
Simple interest for any principal amount p , rate of interest r and time t is given by
Simple interest = (p*r*t)/100
_________________________________
Given
p =$500
r = 3%
t = 10 years
Therefore SI = $500*3*10/100 = $150.
$150 is earned in 10 years at 3% simple interest on $500.
The ratio is 1/1.5 so just pick the answers where the first number multiplied by 1.5 is equal to the second number.
For example the first option says 2 and 3.
2 times 1.5 is equal 3 so that is one of the answers.
If an option says 4 and 5, 4 times 1.5 is 6 not 5 so that wouldn't be an answer.
The last one : y - 5 = (x - 6)
the equation of a line in point- slope form is
y - b = m(x - a )
where m is the slope and (a, b ) a point on the line
to calculate m use the gradient formula
m = ( y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = A(- 2, - 1 ) and (x₂, y₂ ) = (B(6, 5 )
m = = =
using (a, b ) = (6, 5 ), then
y - 5 = (x - 6 ) ← in point- slope form
the given expression is,
5x - (x +1) = 5 - 2x
5x - x - 1 = 5 -2x
4x + 2x = 5+1
6x = 6
x = 6/6
x = 1
thus, the answer is x = 1
