Answer:
The Annual rate of interest for the mortgage is 1.8%
Step-by-step explanation:
Given as :
The mortgage principal = p = $167,000
The time period of mortgage = t = 20 years
The Amount paid towards mortgage in 20 years = A = $240,141
Let the Annual percentage rate on interest = r % compounded annually
Now, <u>From Compound Interest method</u>
Amount = Principal ×
Or, A = p ×
Or, $240,141 = $167,000 ×
or, =
Or , 1.437 =
Or, =
or, 1.018 =
Or, = 1.018 - 1
Or, = 0.018
∴ r = 0.018 × 100
i.e r = 1.8
So, The rate of interest applied = r = 1.8 %
Hence, The Annual rate of interest for the mortgage is 1.8% Answer
Answer:
Aidan is 2 miles far from the ending point when he reaches the water station.
Step-by-step explanation:
The locations of the starting point, water station and ending point are (3, 1), (3, 7) and (3, 9), all expressed in miles. First we determine the distances between starting and ending points and between starting point and water station by the Pythagorean Theorem:
From starting point to ending point:
(Eq. 1)
From starting point to water station:
(Eq. 2)
The distance between the water station and the ending point is:
(Eq. 3)
Hence, Aidan is 2 miles far from the ending point when he reaches the water station.
