Answer:
$70,201.38
Step-by-step explanation:
To determine the principal amount, we can use the formula:
A = $200,000
r = 7% or 0.07
t = 15 years
n = 12
Now let's substitute our values.
So the principal needed to get 200,000 in 15 years is $70,201.38.

The height of a rectangular pyramid is 30 cm.
volume of rectangular pyramid = (length x width x height) / 3
Given:
Volume = 900 cm³
Length = 10 cm
Width = 9 cm
Height = ?
V = lwh/3
900 cm³ = (10cm * 9cm * h)/3
900 cm³ * 3 = (90cm² * h)/3 * 3
2700 cm³ = 90cm² * h
2700 cm³/90cm² = 90cm² * h/90 cm²
30 cm = h
to check:
900 cm³ = (10 cm * 9 cm * 30 cm)/3
900 cm³ = 2700 cm³/3
900 cm³ = 900 cm³
Answer:
with discount+tax= $23.15
Step-by-step explanation:
board game is 25
discount: 15%
tax: 7.5%
discount means you take off that amount
tax means you add that amount
discount: 15% off
tax: +7.5%
to find 15% of 25 multiply 25 by 15% (15/100=0.15)
25*0.15
= 3.75
then subtract that from 25
25-3.75
=21.25
tax:
0.075*25
=1.875
~1.9
21.25+1.9
=23.15
