Answer:
y/x
Explanation:
The constant of proportionality defines two directly proportional quantities that decrease or increase proportionally/same rate.
Given constant of proportionality= k
Side of the square= x
Perimeter of the square= y
constant of proportionality=k=y/x
For example if perimeter of square is 8 and side of square is 2, constant of proportionality is 8/2=4
A^2 + b^2 = c^2
a^2 + 15^2 = 17^2
a^2 + 225 = 289
a^2 = 289 - 225
a^2 = 64
sqrt of 64 = 8
a = 8
x = 8

Answer:
C
Step-by-step explanation:
There is a common ratio between consecutive term in the sequence, that is
÷
= 3 ÷
= 30 ÷ 3 = 300 ÷ 30 = 10
This indicates the sequence is geometric with n th term
= a
where a is the first term and r the common ratio
Here a =
and r = 10 , thus
=

=
× 
= 3 ×
× 
= 3 × 
Thus
= 3
→ C
Answer: 
Step-by-step explanation:
Given
Kira order 2 pieces of tuna and 5 pieces of crab
While Marcy ordered 3 pieces of tuna and 6 pieces of crab
Total tuna ordered =2+3=5 pieces
Total crab ordered=5+6=11 pieces
The ratio of Tuna and crab is
