The diameter of a quarter is about 2.4 cm what is the circumference of a quarter
Answers
The circumference of a quarter is approximately 7.536 cm.
What is Circle?
A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.
The circumference of a circle is given by the formula:
C = πd
where C is the circumference, d is the diameter, and π (pi) is a mathematical constant approximately equal to 3.14.
Substituting the given diameter of a quarter, which is 2.4 cm, into the formula:
C = πd
C = π(2.4 cm)
C = 7.536 cm
Therefore, the circumference of a quarter is approximately 7.536 cm.

How much does it cost to make 3 widgets?
Answers
Answer:
The total cost to make 3 widgets is $64.
Step-by-step explanation:
As cost is give by quadratic function such as
As it costs $29 to produce 2 widgets. So,
As it costs $115 to produce 4 widgets. So,
As it costs $757 to produce 10 widgets. So,
In order to find the values of a, b, c and d, we have to equations [A], [B] and [C]
Subtracting Equation [A] from [B] and [B] from [C]
12a + 2b = 86 ........[D]
84a + 6b = 642 ........[E]
Multiplying Equation [D] by 3 and subtracting from [E]
84a + 6b + 3(12a + 2b) = 642 - 86
48a = 384
a = 8
Putting value of a = 8 in equation [D]
12(8) + 2b = 86
96 + 2b = 86
2b = -10
b = -5
Substituting the value of a = 8 and b = -5 in Equation [A].
29= 4a+2b+d
29 = 4(8) + 2(-5) + d
29 = 32 - 10 + d
d = 29 + 10 - 32
d = 7
The required form of equation can be obtained by substituting a = 8, b = -5 and d = 7 in the cost equation. So,
is the required form of equation.
Therefore, the total cost to make 3 widgets will be:
Putting x = 3 in
Hence, the total cost to make 3 widgets is $64.

To solve this question, we must isolate the h
Subtract 3h from both sides
2h (-3h) + 8 > 3h (-3h) - 6
2h - 3h + 8 > -6
-h + 8 > - 6
Subtract 8 from both sides to isolate the h
-h + 8 (-8) > - 6 (-8)
-h > - 6 - 8
-h > -14
Finally, isolate the h by making it a positive. To do so, divide - 1 from both sides. Note that when you divide a negative number, you must flip the sign.
-h/-1 > - 14/-1
h < 14
h < 14, or (1) is your answer

b.write the equation in slope intercept form.
c.what is the setup fee?
Answers
Final answer:
The setup fee for the cable service can be found by creating an equation using the given point and solving for the y-intercept. This y-intercept, in this context, represents the setup fee.
Explanation:
Firstly, we understand that the cost per month for the premium cable is $39.95. Considering this cost as a rate, we can say that the total monthly cost can be calculated by multiplying the number of months with the rate per month. The setup fee is a fixed cost, and thus it doesn't change with the number of months.
To find this setup fee, we need to find the y-intercept. In this situation, the y-intercept, denoted usually as b in the slope-intercept form equation y = mx + b, is the setup fee.
So let's solve it step-by-step:
- Given the point (6, 264.70) substitutes into the equation as x and y. We can set up the following equation from this point: 264.70 = 39.95*6 + b.
- After multiplying and subtracting, we solve for b. The value of b comes out to be the setup fee.
So, the setup fee is found out by subtracting from the total cost of 6 months, the cost of the cable service for these 6 months.
