Answer:
Step-by-step explanation:
Given: In a parallelogram ABCD, diagonals intersect at O and ar(ABCD) is .
We need to find the area of triangle AOB.
We know that each diagonal divide the parallelogram in two equal parts and diagonals bisect each other.
It means both diagonals divide the parallelogram in 4 equal parts.
Hence, the values of ar(AOB) is .
Answer:
Each person will pay $9.78
Step-by-step explanation:
Given that:
Amount of bill = $34
Tip = 15%
Amount of tip =
Amount of tip = 0.15 * 34
Amount of tip = $5.10
Amount after bill = 34 + 5.10 = $39.10
Number of people = William + three friends = 4
Per person share =
Per person share = $9.775
Rounded to two decimal places
Per person share = $9.78
Hence,
Each person will pay $9.78
Step-by-step explanation:
i = interest 3% for 30 years
This is a simple dynamical system for whom the the solutions are given as
putting values we get
S=2000[\frac{(1.03)^{30}-1}{0.03}](1.03)
= $98005.35
withdrawal of money takes place from one year after last payment
To determine the result we use the present value formula of an annuity date
we need to calculate R so putting the values and solving for R we get
R= $6542.2356
