Can you take a better picture
Complementary means that the two angles sum to 90 degrees.
So based on the problem, let:
1st angle=5x+6
2nd angle=x
Now create an equation.
x+5x+6=90
6x=84
x=14
5x+6=76
answer: 14 degrees and 76 degrees
1 steak costs $9.99
2 steaks cost 2*9.99 = $19.98
This is before tax is applied
Apply the 6% tax to get
6% of 19.98 = (6/100)*19.98 = 0.06*19.98 = 1.1988
which rounds to 1.20 (rounded to the nearest penny)
The sales tax is therefore $1.20
Add this to the previous total (19.98) and we get a grand total of 19.98+1.20 = 21.18 which is the final cost (with tax included)
note: we can multiply 19.98 by the value 1.06 to get 19.98*1.06 = 21.1788 and that rounds to 21.18; so it's a different route to the second answer
Answer:
a = 370,000
b = 2,115,000
c = 4,230,000
city c is 11.4 times the population of city a
Step-by-step explanation:
10 to the 5 degree is 100,000. multiply that by 3.7 to get the population of City a.
City C is 2,115,000 * 2.
divide the population of City C by the population of City a.
4,230,000 ÷ 370,000= 11.43
