Gas prices have increased steadily from $2.35 per gallon to $3.95 per gallon in 8 months. What is the rate of change in gasoline prices per month?
Answers
Answer:
The rate of change in gasoline is 0.2$ per month.
Step-by-step explanation:
Given that Gas prices have increased steadily from $2.35 per gallon to $3.95 per gallon in 8 months.
Increase 'steadily' means the rate of change is the same throughout the 8 months.
let x represents the time in months, and y represents the gas price
so
at x₁ = 0, y₁ = 2.35
at x₂ = 8, y₂ = 3.95
Let us find the slope or rate of change using the formula
Rate of change = slope = m = [y₂ - y₁] / [x₂ - x₁]
= [3.95 - 2.35] / [8 - 0]
= 1.6 / 8
= 0.2 $ per month
Therefore, the rate of change in gasoline is 0.2$ per month.
The cost of renting a canoe is $8 for the first hour plus another $3 for each
additional hour. Which of the following represents this situation, where Cis
the total cost of renting a canoe for h hours?
Answers
The option that represents the situation correctly is C. C = 3h + 8 is incorrect because it doesn't take into account the fixed cost of $8 for the first hour.
What is algebra?
Algebra is a branch of mathematics that deals with mathematical operations and symbols used to represent numbers and quantities in equations and formulas. It involves the study of variables, expressions, equations, and functions.
The cost of renting a canoe is a fixed $8 for the first hour plus $3 for each additional hour. This can be expressed as:
C = 8 + 3(h - 1)
Where h - 1 represents the number of additional hours beyond the first hour. Simplifying this equation, we get:
C = 3h - 3 + 8
C = 3h + 5
Therefore, the option that represents the situation correctly is C.
C. C = 3h + 8 is incorrect because it doesn't take into account the fixed cost of $8 for the first hour.
A. C = 3(h-1) + 8 is also incorrect because it doesn't add the fixed cost of $8 for the first hour.
D. C = 8h + 3 is incorrect because it incorrectly assumes that the $3 additional charge is applied to the first hour as well.

Answers
Answer: d 10900
Step-by-step explanation:
The value of machinery after 4 years is $6,100, So option 'C' is the correct answer to the following question.
Value function based problem:What information do we have?
f(t) = 12,500 - 1,600t
Time taken = 4 year
Function
f(t) = 12,500 - 1,600t
f(4) = 12,500 - 1,600(4)
f(t) = 12,500 - 6,400
Value function = $6,100

Everything is add up to 180
M < 5 = 3(m<3)
If m< 3 = x
M<5+m<3= 180
3x+x= 180
3x+x = 4x
So we divide 4
X =180/4 = 45
A water tank measures 20 cm by 50 cm by 30 cm
if each of these measurements is given to the nearest centimeter, calculate the largest
possible volume of the tank.
Answers
The largest possible volume of the tank, considering the given measurements to the nearest centimeter, is approximately 31575.125 cubic centimeters.
We have,
To calculate the largest possible volume of the tank, we need to consider the measurements given to the nearest centimeter.
When measurements are given to the nearest unit, it means they can vary by up to half of the unit in either direction.
For the dimensions of the tank:
Length: 20 cm (can vary from 19.5 cm to 20.5 cm)
Width: 50 cm (can vary from 49.5 cm to 50.5 cm)
Height: 30 cm (can vary from 29.5 cm to 30.5 cm)
To find the largest possible volume, we need to use the maximum values for each dimension.
Using the upper limit for each measurement, the largest possible volume can be calculated as follows:
Volume = Length × Width × Height
= (20.5 cm) × (50.5 cm) × (30.5 cm)
= 31575.125 cubic centimeters
Therefore,
The largest possible volume of the tank, considering the given measurements to the nearest centimeter, is approximately 31575.125 cubic centimeters.
