Answer:
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
Step-by-step explanation:
6x + 4x = 700
10x = 700
x = 700/10 = 70
One num = 6x = 6 x 70 = 420
Second= 4x = 4 x 70 = 280
I hope im right!
78- acute
144- obtuse
This is because anything less than 90 degrees is acute. Think of it as they are cute because they are tiny xD
=90 is right angel
And anything above 90 and below 360 is obtuse because it's fat xD

Answer:
.86
Step-by-step explanation:
Exponential function formula
where a = initial value
r = rate of change
and t = number of years
given the equation y = 34000(0.86)^x.
r = .86
Hence the change factor is .86
