For this case we have a function of the form:
y = A (b) ^ x
Where,
A: initial amount
b: decrease rate
x: time
We have then:
b = 0.15
Therefore the percentage of decrease is:
(1-0.15) * 100 = 75%
Answer:
75%
option 3
Answer:
22 + 4x = 90
4x = 68
<u>x = 17</u>
Step-by-step explanation:
Answer:
the angle are 50, 47, 83
Step-by-step explanation:
we know that the sum of the three angles of the triangle is 180 degree
now, 4x+22+3x+26+9x+20=180
x=7
the angle are 50, 47, 83
1)325in^2
2) 439484ft^2
3)5382yd^2
4)10.53ft^2
