<span>Let x = represent the number of weeks of deposits
A = 120 + 5x the account balance after x weeks
The account balance is directly proportional to the number of weeks of deposits if:
A/x = constant
(120 + 5x)/x = 120/x + 5 is not a constant
For example:
After 1 week there will be: 120 + 1*5 = $125 on the account
After 2 week there will be: 120 + 2*5 = $130 on the account
After 3 week there will be: 120 + 3*5 = $135 on the account
But 125/1 <> 130/2 <> 135/3
The account balance is not proportional to the number of weeks of deposits.</span>

Answer:
6 in = 80 miles
Step-by-step explanation:
Given that:
Distance between Capeton and Jonesville = 80 miles.
Map scale : 0.75 in = 10 miles ; this means 0.75 inches on the map represents 10 miles on land.
Hence, If ;
0.75 inches = 10 miles
x inches = 80 miles
Cross multiply :
10 * x = 80 * 0.75
10x = 60
10x / 10 = 60 / 10
x = 6 inches
Hence,
6 in = 80 miles
Answer:
278.9 units^3 to the nearest tenth.
Step-by-step explanation:
This is a cylinder on the bottom . resting on the cylinder is a prism.
Volume of the cylinder = π r^2 h where r = 1/2 * 7 = 3.5 and h = 6.
V = π * 3.5^2 * 6 = 230.907 units^3.
Volume of the prism = l*w*h
= 4*4*3 = 48 units^3.
Volume of the composite figure = 230.907 + 48
= 278.9.
