Answer:
≈44.44%
Step-by-step explanation:
≈44.44%
To solve this, we can use a simple proportion.
Assuming 18 = 100%...
Then, using cross multiplication...
Now divide 18 from both sides.
x ≈ 144.44
Now subtract 100 from ≈144.44, leaving us with
≈44.44%
Answer:
$105 (Make sure to read the explanation)
Step-by-step explanation:
120.45 + 95.75 + 105.32 + 140.25 + 89.68 + 101.32 = 652.77
652.77 ÷ 6 = 108.795
I think the mean as her budget is a tiny weny too high so I think $105 is a good enough budget. Feel free to change it.
if an ordered pair is a solution, it should satisfy the equation.
see the first option
, if you put $x=4$ and $y=12$
you'll get $12=12$ which is true.
now the last option, $y=8-x$ put $x=4$ and $y=12$
$12=8-4\implies 12\ne4$ thus it is not a solution.
So option 4 is correct
Answer:
12.
Step-by-step explanation:
According to Pythagorean's Theorem, x^2+25=169. If you subtract 25 from both sides, you might get x^2=144. You then square both sides and get that x=12.
Answer:
$445.2
Step-by-step explanation:
If the sales tax is 6%, she is paying 106% of the original price. 6% of 420 is 25.2.
420+25.2 equals 445.2 $
