D. Three less than five times the quantity of a number plus two.
The answer is A. Working the formula backwards you get that r^2=256, so r=16
2 is true since the absolute value of -6 is 6 and the absolute value of -8 is 8. The absolute value of a number will always be the number itself but positive. Also 6 is less than five which make this true.
Answer:
not enough seats
Step-by-step explanation:
12 rows of 14 seats is ...
12 × 14 seats = 168 seats
8 rows of 12 seats is ...
8 × 12 seats = 96 seats
Then the total number of seats is ...
168 seats + 96 seats = 264 seats
This is fewer than 272, so there will not be enough seats for everyone.
<span>Y varies jointly with w and x, inversely with z
this means that
</span>y ∝ wx / z
in equation form
y = kwx / z
where k is the proportionality constant
360 = k ( 8 ) ( 15 ) / 3
k = (360) ( 3) / ( 8 ) ( 15 )
k = 9
so the eqution is
y = 9wx / z
