Answer:The simple interest rate is 7.50%
Step-by-step explanation:
Simple interest, I =( P × T × R) / 100
Where P= Principal investment
T = Time in years
R = rate
Given
P= 981.60
I = 1000 - 981.60 = 18 .40
T = 13 weeks = 13 / 52 = 0.25 year
I =( P × T × R) / 100
Cross multiply
I × 100 = P × T × R
18.40 × 100 = 981.60 × 0.25 × R
1840 = 245.4 R
R= 1840 / 245.4
R = 7.498%
To the nearest tenth
R = 7.50%
Answer:
x = 20
Step-by-step explanation:
The interior angles of a regular octagon have measures of ...
180° -360°/8 = 135°
We want that equal to the given expression.
7x -5 = 135
7x = 140 . . . . add 5
x = 20 . . . . . divide by 7
The value of x is 20.
Hello!
Answer:
x=10/3
Step-by-step explanation:
First you want start by adding 4 to both sides
6x-4+4=16+4
6x=20
Then divide 6 to both sides,
6x/6=20/6
x= 10/3
Hope this helps! :)
