The future value of cash whose initial value is $845, at the rate of 11.3% for 7 years will be calculated using the compound interest rate, that is:
A=p(1+r/100)^n
where:
A=future amount
r=rate=11.3%=0.113
time=7 years
thus the future value of our cash will be:
A=845(1+0.113)^7
A=845(1.113)^7
A=$1,787.82
Answer:
71
Step-by-step explanation:
in a triangle all the angles together equal 180°. So all you have to do is add 43 + 66=109 and then subtract that from 180
Answer:
4 minutes
Step-by-step explanation:
make equation
0.25+(0.15x)= 0.85
solve for x
0.15x= 0.60
x=4
Answer:
The width of rectangle w = 4 units
Step-by-step explanation:
We are given:
Width of rectangle = w
Length of rectangle = w+ 4
Area of rectangle = 32 units
We need to find width of the rectangle
The formula used is: 
Putting values and finding width of rectangle

We need to solve this quadratic equation to find width (w)
We will use factorisation and break the middle term.

Since width of rectangle can't be negative, so rejecting w=-8
Therefore, the width of rectangle w = 4 units
