we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y=kx
where
k is the constant of proportionality
Verify each table
table a
Let
x ----> distance
y ----> sound level
For each ordered pair calculate the value of k
k=y/x
so
(5,85) -----> k=85/5=17
(10,79) ----> k=79/10=7.9
the values of k are differents
that means
the table nor represent a proportional relationship
table b
let
x ----> volume
y ----> cost
k=y/x
(16,1.49) ----> k=1.49/16=0.093125
(20,1.59) ----> k=1.59/20=0.0795
the values of k are differents
that means
the table nor represent a proportional relationship
Answer:
1/12 of the original
Step-by-step explanation:
If you split 1/4 into 3 equal pieces, then each friend gets 1/12 of the original cake
I think that 10 is 20% of 50
Answer:
the total pay for the month for appliance salesperson = $6680.25
Step-by-step explanation:
salesperson receives a monthly salary of $2,250
commission of 4.5% on all sales compute
total pay for a month and when she sold $98,450 worth of appliances
total pay = $2,250 + 4.5% of $98,450
= $2,250 + $4430.25 = $6680.25
Volume = 28 in squared
surface area = 44 in
