Hey!
What I did was I graphed them or you could set them equal to each other and use logs!
I graphed them and found the intersections. There were 2, but one was negative so I checked for a positive intersection and found one.
The first blank is 7 and the other is 140!
Hope this helps!
Answer:
in explanation
Step-by-step explanation:
angle rules say that those angles respond to each other meaning
they will equal each other
so 6x-4=4x+14
now solve for x
x=9
the top angle will be
6(9)-4=50
bottom angle will be 50
4(9)+14=50
Answer:
0.2% of the people had mid allergic reaction.
Step-by-step explanation:
Given that:
Number of people tested for a new shampoo = 9000
Number of people who had allergic reaction = 18
Percent of people = 
Percent of people = 
Percent of people = 0.002 * 100
Percent of people = 0.2%
Hence,
0.2% of the people had mid allergic reaction.
Percent formula : is/of = %/100
is = 12
of = 60
% = x
now we sub
12/60 = x/100
cross multiply
(60)(x) = (12)(100)
60x = 1200
x = 1200/60
x = 20
check..
0.20(60) = 12
12 = 12 (correct)
so 20% of 60 is 12
since nalah is 10 years old and she got the doll when she was 6 we can do 10 - 6 = 4 so 4 years she has had the doll.
