Answer:
In fifteen years, Alexis would have 9200. In twenty years she would have 9600
Step-by-step explanation:
10% for interest of 8000= 80.
80 (interest for one year) * 15 (fifteen years)= 1200
1200 plus the original amount is 9200.
80 (interest for one year) * 20 ( twenty years)= 1600
1600 plus the original amount is 9600
Can’t help with that sorry
Answer:
Answer:
8
Step-by-step explanation:
x= centesimal angle (100 degrees in a
right angle)
y= sexagesimal angle (90 degrees in a
right angle)
=
x - y = 15
xx90/100 = y
xx9/10 = y
X - XX9/10 = 15
10x/10 - 9x/10 = 15
=
X/10 = 15
x= 150
y = 150x9/10 = 15x9 = 135
=
using centesimal system:
the sum of all external angles in a
polygon is 400 degrees (a full circle).
one external angle is the complement
of one internal angle to 200 degrees =
200-150=50 degrees.
to find the number of sides of the
polygon we need to find the number of
angles or corners. and that is how many
external angles fit into the full circle.
n = 400/50 = 8
=
the polygon has 8 sides
Answer:
4th option: 38t = 532
Step-by-step explanation:
t = 38
?t = 532
14t =532
I don't really know how to explain this but basically, we know 1t is 38, so we know 38 x t will give use 532. This is why I chose the last equation of:
38t = 532
The answer would be 14 trips just for extra information.
