Answer:
The correct answer is 30
Step-by-step explanation:
Given: The x-axis represents the time in hours and the y-axis represents the distance in miles.
The line passes through the points and
To find: The rise-over-run value for the relationship in the graph.
Thus, the rise-over-run value for the relationship represented in the graph is 30.
Answer:
Brand A is the better deal!
Step-by-step explanation:
Let's start by comparing.
We know brand B has the following cost: 5 ounces = $3.75
10 ounces $7.50 and 16 ounces = $12
Now check the graph.
6 ounces cost $3
12 ounces cost $6
20 ounces cost $10
I don't think we need to look any further but brand A is the better deal!
It could be any thing as long it is reasonable . I would say 250 because 500-250.

Answer:
(1 ) Inner curved surface area of the well is 109.9 sq. meters.
(2) The cost of plastering the total curved surface area is 4396.
Step-by-step explanation:
The inner diameter = 3.5 m
Depth of the well = 10 m
Now, Diameter = 2 x Radius
⇒R = D/ 2 = 3.5/2 = 1.75
or, the inner radius of the well = 1.75 m
CURVED SURFACE AREA of cylinder = 2πr h
⇒The inner curved surface area = 2πr h = 2 ( 3.14) (1.75)(10)
= 109 sq. meters
Hence, the inner curved surface area of the well is 109.9 sq. meters.
Now, the cost of plastering the curved area is 40 per sq meters
So, the cost of total plastering total area = 109.9 x(Cost per meter sq.)
= 109.9 x (40)
= 4396
Hence, the cost of plastering the total curved surface area is 4396.
