Please help on question 3
Answer: 36
Step-by-step explanation:
Circumference is [tex]C=d\pi[/tex]
Diameter is 2r
Diameter is 14
[tex]\pi[/tex]= 22/7
[tex]C=14(\frac{22}{7} )[/tex]
C=44
half the circumference is 22- so the circle part is 22
plus the 14 for the bottom
22+14=36
Clare paid 50% more for her notebook than Priya paid for hers. Priya paid x for her notebook and Clare paid y dollars for hers. Select an equation that represents the relationship between y and x.
The equation y = 1.5x represents the relationship between y and x.
What is an equation?When two mathematical expressions are equivalent to one another in a system of variables, the system is called an equation.
Given that,
Amount paid by Priya for her notebook = x,
Amount paid by Clare for her notebook = y.
Since, Clare paid 50% more for her notebook than Priya.
The equation for the relationship between y and x can be written as,
y = 1.5 x
The required equation is y = 1.5x.

A truck can be rented from Company A for $90 a day plus $0.30 per mile. Company B charges $40 a day plus $0.40 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
At _____ nothing miles, the rental costs are the same from either company.
Answer
The answer is 500 miles
Step-by-step explanation:
So, 500 x 0.40 is equal to $200. And if we add the $40 a day fee it's now $240.
And the other company charges $0.30 a mile. So that equation is:
500 x 0.30 = $150 plus the $90 fee is $240.

the population of center city is modeled by exponential function f, where x is the number of years after the year of 2015. the graph of f is shown on the grid. which inequality best represents the range of f in this situation?
Answer:
the Answer is B) y >= to 250,000
The requried inequality that represents the range of the function shown is f(x) ≥ 250,000.
What is the range?The range is a key concept in the study of sets and it defines as the set of values that come out to an outcome for a certain mathematical operation.
Here,
As mentioned in the question, the population of the central city is modeled by exponential function f, where x is the number of years after the year of 2015.
As the graph starts from 0 (as the year 2015) and goes to an unknown end implying over the x-axis which is its domain. Corresponding to this, the range starts from 250000 on the y-axis and goes to infinity.
Thus, the requried inequality that represents the range of the function shown is f(x) ≥ 250,000.
