Answer:
4(-80) = -320
Step-by-step explanation:
His elevation decreased by 80 each hour. Since he was walking for 4 hours, the equation would be
4(-80) = -320.
Answer:
SAS Congruence Postulate
Step-by-step explanation:
In ΔABC and ΔDCE
AC=CE [given]→Side
∠ACB=∠DCE [vertically opposite angles]→Angle
BC=DC [given]→Side
∴ ΔABC ≅ ΔDCE [SAS congruence postulate]
SAS congruence postulate tells that if two sides and the included angle of one triangle are congruent to two sides and the included angle of other triangle, then the two triangles are congruent.
This is SAS. Notice you have 2 sides that are equal to each other and the vertical angle between them. Since the angle is between the 2 sides then the postulate that works is SAS.
F(3) = 2(3)+6
f(3)= 6+6
f(3)=12

Answer:
Step-by-step explanation:
we know that
The simple interest formula is equal to
where
I is the Final Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
----> one year is equal to 12 months
substitute in the formula above
