As with any "solve for" problem, you undo what has been done to the variable, in reverse order.
Subtract 9, divide by 3, take the 5/3 power
.. 3*(a +4)^(3/5) +9 = 36 . . . . . original equation
.. 3*(a +4)^(3/5) = 27
.. (a +4)^(3/5) = 9
.. a +4 = 9^(5/3)
.. a = 9^(5/3) -4 ≈ 34.9407
Step-by-step explanation:
35%= 650+50
=700
1%= 700÷35
= 20
100%=20×100
= 2000
Answer:
Well it’s like a 50/50 chance. :p
Step-by-step explanation:
to be honest not fully sure
N=1,
a1= 48-1*11=48-11=37
a2= 48 -2*11=48 -22=26
d= 26 -37 = -11
a(n) = a(n-1) - 11
a1=37
a(n) = a(n-1) - 11
Check:
a1=37, a2= a1-11 =37-11=26
a3= 48 -3*11=48-33=15 (using explicit formula),
and a3=a2 - 11=26 -11 =15 (the same answer)
Answer is B.
Answer:
22.7%
Explanation:
Given that last year stock for company A was $7200
The stock for company B last year was worth $3510
Stock in company A decreased by 24%
This means the new value of stock for company A became;
(100-24)/100 *$7200
76/100*$7200
0.76*7200 =$5472
Stock in company B decreased by 20%
This means the new value of stock for company B became;
(100-20)/100 *$3510
80/100*$3510
0.8*$3510
$2808
Original investors stock value was = $7200+$3510 =$10710
New investors stock value is = $5472+$2808=$8280
Decrease in value of stock = $10710-$8280 =$2430
percentage decrease in stock value = decrease in stock/original value of stock *100%
=2430/10710 *100 =22.689
=22.7%
