Step-by-step explanation:
At the dance, soft drinks were 4 for $2.20 this use relationship to fill in the table.
A.) fill in the table:
# of drinks: 1 2 3 4
Princes ($) | | | | |
B.) why is the constant of proportionality?
C.) if you were to buy 22 soft drinks, how much would it cost?
Answer is A
Triangle UVW ~ Triangle UWT ~ Triangle WVT
Local(L) = 1 x (15.99)
Online(O) = (1 x 13.99) + 6
So use that equation until you find the same number.
L1=15.99
O1=19.99
L2=31.98
O2=33.98
L3=47.97
O3=47.97
And your answer will be three from local and three from online.
<span>Chris' average speed is 3.5mph:
Lets take Chris' brother speed = B
then Chris speed = (B+ 1) mph-------given in the question
and:
The average speed for covering 18 miles= chris' average speed + his brother's
average speed = (B+ 1) + B
since Speed = Distance covered / time taken
then average speed for 18 miles can also be found by: 18 miles/3 hours = 6 miles per hour
then we have; (B+ 1) + B = 6mph
(B +1) = (6-B)
B+B = 6-1=5
2B=5
B=5/2=2.5 mph (this is Chris' brother average speed)
Hence Chris' average speed is = B+1= 2.5+1= 3.5mph</span>
A person drives 500 miles in 5 hours.
