To get the radius of a circle in terms of circumference, divide the formula for the circumference by 2π, thus r=C/(2π). The correct option is C: r=C/2(3.14), considering 3.14 is the approximate value of π.
Explanation:The formula for the circumference of a circle is given by C=2πr. We are asked to rearrange this formula to make the radius (r) the subject of the formula. To achieve this, we divide both sides of the equation by 2π.
So, dividing both sides of the equation by 2π gives r=C/(2π).
Looking at your options, Option C: r=C/2(3.14), is correct if we consider 3.14 to be the value of π. Therefore, the radius of a circle in terms of the circumference is given by r=C/(2π).

The ladybugs are planting a garden. They have 25-cm-by-10 cm rectangle for flowers. Each flower needs exactly 1 square centimeter for space. How many flowers can they plant?
Answer: They can plant 250 flowers.
Step-by-step explanation:
Given : The dimension of the rectangular garden = 25-cm-by-10 cm
[i.e. length by width]
Area of rectangle = length x width
⇒ Area of rectangular garden = 25 x 10 = 250 square centimeter .
Area required by each flower = 1 square centimeter
Then, the number of flowers they can plant = [tex]\dfrac{\text{Area of garden}}{\text{Area of needed by each flower}}[/tex]
[tex]=\dfrac{250}{1}=250[/tex]
Hence, they can plant 250 flowers.

How to determine the function is even odd or neither
f(x)=5-3x
if the function is mirrored about the y axis, it is even
use -x in place of x and compare the equations
lets use 2 for x
so given formula would be 5-3(2) = 5-6 = -1
replace x with -x you would have 5-3(-2) =5-(-6) = 5+6 =11
since -1 does not = 11 the function is neither
even =f(x), odd = -f(x), neither f(x) doesn't equal -f(x)
example of odd:
f(x) = x^5 +x, replace x with -x
f(-x) = (-x)^5 +-x
=-x^5-x
=-(x^5+x)
=-f(x)
ODD
Example of even:
f(x) = 1-x^4
f(-x) = 1-(-x)^4
=1-x^4
=f(x)
EVEN
Example of Neither:
f(x) = 2x-x^2
f(-x) = 2(-x)-(-x)^2
=-(2x+x^2)
does not equal f(x)
NEITHER

A model is made of a car. The car is 10 feet long and the model is 7 inches long. What is the ratio of the length of the car to the length of the model? A. 10 : 7 B. 7 : 120 C. 120 : 7 D. 7 : 10
Final answer:
To find the ratio of the car's length to the model's length, first convert the car's length to inches (120 inches), then compare it to the model's length (7 inches), which gives a ratio of 120 : 7.
Explanation:
The question asks for the ratio of the length of the car to the length of the model. First, it's essential to convert both measurements to the same unit for an accurate comparison. The car is 10 feet long, and since 1 foot equals 12 inches, the car's length in inches is 10 feet × 12 inches/foot = 120 inches. The model is 7 inches long. Therefore, the ratio of the length of the car to the length of the model is 120 inches to 7 inches, which simplifies to 120 : 7.

The linear function c = 2 y + 29 models the average cost of a haircut in a certain city, where c, is the average price of a haircut y years after 1995. find the slope for the model. then describe what this means in terms of the rate of change in the average cost of a haircut over time
The rate of change implies that the city's haircut prices are consistently going up over time.
The given linear function is c=2y+29, where c represents the average cost of a haircut y years after 1995.
The slope of the linear function, 2, reflects the rate of change in the average cost of a haircut over time.
This means that for each year after 1995, the average cost of a haircut increases by $2. In other words, the slope indicates that the cost of haircuts is rising at a constant rate of $2 per year. This steady increase implies that the city's haircut prices are consistently going up over time.
The positive slope signifies that the average cost is consistently moving upward as the year progresses. Customers can expect to pay, on average, $2 more for a haircut each year compared to the previous year.

The slope of the linear function c = 2y + 29 is 2, indicating that the average cost of a haircut increases by 2 units for every 1 increase in the number of years after 1995.
Explanation:The slope of a linear function represents the rate of change. In the given linear function c = 2y + 29, the slope is the coefficient of y, which is 2. This means that for every 1 increase in y (number of years after 1995), the average cost of a haircut will increase by 2 units.

Employees in 2012 paid 4.2% of their gross wages towards social security (FICA tax), while employers paid another 6.2%. How much will someone earning $45,000 a year pay towards social security out of their gross wages?
Answer:
The answer is $1890.
Step-by-step explanation:
Employees in 2012 paid 4.2% of their gross wages towards social security (FICA tax)
While employers paid another 6.2%.
So, someone earning $45000, will pay [tex]0.042\times45000=1890[/tex] dollars in FICA.
The question says only individual. The earnings are exclusive to employees, so they will only pay from earnings. The employer will not pay from employee's earnings.
The answer is $1890.
The number of earnings towards social security should be $1,890.
Given that,
The employers in 2012 paid 4.2%.The employer should paid 6.2%.And, the earning should be $45,000.Based on the above information, the calculation is as follows:
[tex]= 4.2\% \times \$45,000[/tex]
= $1,890
Therefore we can conclude that the number of earnings towards social security should be $1,890.

(b) the water level drops at a rate of 0.1 cm per hour. at what rate is the radius of the water decreasing when the depth is 4 cm? round your answer to four decimal places.
The rate at which the radius of the water is decreasing when the depth is 4 cm is 0.6949 cm/hr.
Explanation:To find the rate at which the radius of the water is decreasing, we can use the chain rule from calculus. Let's denote the depth of the water as 'h' and the radius as 'r'. We are given that the water level drops at a rate of 0.1 cm per hour, so dh/dt = -0.1 cm/hr. We want to find dr/dt when h = 4 cm. Using the formula for the volume of a cone, V = (1/3)πr^2h, we can find the relationship between r and h: r = √((3V)/(πh)). Taking the derivative of this equation with respect to time, we have: dr/dt = (√((3V)/(πh)))' = -(3/2)(√((3V)/(πh^3)))(dh/dt). Plugging in the given values and solving for dr/dt when h = 4 cm, we get:
dr/dt = -(3/2)(√((3(350))/(π(4)^3)))(-0.1) = 0.6949 cm/hr

if you deposit $4000 into an account paying 9% annual interest compounded monthly, how long until there is $10000 in the account?
To determine how long it will take for $4000 to grow to $10000 with an interest rate of 9% compounded monthly, we can use the formula for compound interest and solve for t. The time t is approximately 7.17 years.
Explanation:To find out how long it will take for $4000 to grow to $10000 at an interest rate of 9% compounded monthly, we can use the formula for compound interest:
A = P(1 + r/n)^(nt)
Where:
A = total amount after time t
P = principal amount (initial deposit)
r = annual interest rate (as a decimal)
n = number of times interest is compounded per year
t = number of years
By plugging in the given values, we can solve for t:
$10000 = $4000(1 + 0.09/12)^(12t)
Dividing both sides by $4000, we get:
2.5 = (1 + 0.0075)^(12t)
Taking the natural logarithm of both sides, we have:
ln(2.5) = ln(1.0075)^(12t)
Using logarithmic properties, we can isolate t:
12t = ln(2.5) / ln(1.0075)
t = ln(2.5) / (12 * ln(1.0075))
Calculating the value of t, we find that it will take approximately 7.17 years for the account to reach $10000.
