The area of a circle is 16π ft². What is the circumference, in feet? Express your answer in terms of \piπ.

Answers

Answer 1

The circumference when the area of a circle is 16π ft² is 8π feet.

How to calculate the area?

The area of a shape simply means the total space that is taken by the shape. It simply expresses the extent of the region on a particular plane as well as a curved surface.

From the information given the area of a circle is 16π ft² be we want to calculate the circumference, in feet. This will be Illustrated this:

Circumference of a circle = 2πr

Area of a circle = πr²

r = radius.

Therefore, based on the information regarding the area given, the radius will have to be calculated first.

Area = 16π

πr² = 16π

r² = 16π / π

r² = 16

r =✓16

r = 4

Radius = 4ft.

Therefore, the circumference will be:

= 2πr

= 2 × π × 4

= 8π

Circumference is 8π feet.

your group fundraiser has a goal of $75 to pay for a new piece of equipment. you are selling pencils () for $0.50 and bracelets () for $1.00.

Answers

To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.

To reach your fundraising goal of $75, you can sell pencils for $0.50 and bracelets for $1.00.

1. Calculate the total amount of money needed to reach the goal:
  Goal amount = $75

2. Determine the number of pencils and bracelets you need to sell to reach the goal:
  Let's assume you sell x number of pencils and y number of bracelets.

  The amount raised from selling pencils = x * $0.50
  The amount raised from selling bracelets = y * $1.00

  The total amount raised from both items should be equal to the goal amount:
  x * $0.50 + y * $1.00 = $75

3. Simplify the equation:
  0.50x + 1.00y = 75

4. Solve for one variable in terms of the other:
  Let's solve for x in terms of y:
  0.50x = 75 - 1.00y
  x = (75 - 1.00y) / 0.50

5. Substitute the value of x into the equation:
  (75 - 1.00y) / 0.50 * 0.50 + y * $1.00 = $75
  75 - 2y + y = 75
  -y = 0
  y = 0

6. Find the value of x:
  x = (75 - 1.00 * 0) / 0.50
  x = 75 / 0.50
  x = 150

To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.

16. p(ski | does not snowboard)
a. 3/17 b.7/17 c.3/7 d. 3/13
- this is the part i need help with

Answers

The correct option is b) In order to determine the probability of skiing given that someone does not snowboard, we need to use conditional probability. We know that the probability of not snowboarding is 1 minus the probability of snowboarding, which is 1 - 7/17 = 10/17.

Now, we can use Bayes' theorem to find the probability of skiing given that someone does not snowboard:

P(ski | not snowboard) = P(not snowboard | ski) * P(ski) / P(not snowboard)

We don't have the probability of not snowboarding given that someone skis, so we have to assume that it's the same as the probability of not skiing given that someone snowboards, which is 3/7. We also know that the probability of skiing is 3/13. So, plugging these values into the formula:

P(ski | not snowboard) = (3/7) * (3/13) / (10/17) = 27/130

A ball was dropped from a height of 60m. Each time it hit the ground, it bounced up 1/2 (half) of the height that it dropped. How far had the ball travelled when it hit the ground for the fifth time?

Answers

Answer:

The ball traveled 116.25 m when it hit the ground for the fifth term

Step-by-step explanation:

This is a geometric progression exercise and what we are asked to look for is the sum of a GP.

The ball was dropped from a height of 60 m. This means that the initial height of the ball is 60 m.

First value, a = 60

Each time it hit the ground, it bounced up 1/2 (half) of the height that it dropped.

This is the common ratio, r = 1/2 = 0.5

The number of terms it hits the ground is the number of terms in the GP.

number of terms, n = 5

The distance traveled by the ball when it hit the ground for the fifth term will be modeled by the equation:

\(S_n = \frac{a(1 - r^n) }{1 - r} \\S_5 = \frac{60(1 - 0.5^5) }{1 - 0.5}\\S_5 = \frac{58.125}{0.5} \\S_5 = 116.25 m\)

*First: We write the equations that we can derivate from the text, those are:

\(63=w+l\)

&

\(l=2x+7\)

\(w=x\)

*Second: We will replace this last two equations in the first one and solve for x:

\(63=2(x)+(2x+7)\Rightarrow63=4x+7\)\(\Rightarrow56=4x\Rightarrow14=x\)

So, we have that the width of the patio is 14 feet long.

*Third: We determine the length:

\(l=2(14)+7\Rightarrow l=35\)

Answers

The given linear programming problem aims to maximize the objective function \(Z = 3x1 + 2x2\), subject to four constraints: x1 ≤ 4, x2 ≤ 6, 3x1 + 2x2 ≤ 18, and x1 ≥ 0, x2 ≥ 0.

The objective of linear programming is to optimize (maximize or minimize) a linear objective function while satisfying a set of linear constraints. In this case, the objective is to maximize \(Z = 3x1 + 2x2\).

The constraints in the problem define the feasible region, which is the set of all points that satisfy the constraints. The constraints state that x1 must be less than or equal to 4, x2 must be less than or equal to 6, and the linear combination \(3x1 + 2x2\) must be less than or equal to 18. Additionally, both x1 and x2 must be greater than or equal to zero.

To solve this linear programming problem, graphical methods or optimization algorithms such as the simplex method can be employed. The feasible region is determined by graphing the constraints and finding the overlapping region. The optimal solution is the point within the feasible region that maximizes the objective function.

The explanation of the solution, including the optimal values of x1 and x2, the maximum value of Z, and the graphical representation of the problem, can be provided based on the chosen method of solving the linear programming problem.

(not including benefits or

Answers

The 14.9% increase in Sylvia's lead lathe tech's hourly wage of $18.50 results in a $2.75 per hour increase. Assuming the lead lathe tech works 2,080 hours per year, the additional cost to Sylvia's annual wages budget would be approximately $5,720, excluding benefits or taxes.

First, we need to find the percentage increase in the lead lathe tech's hourly wage. The increase requested is $2.75, which is 14.9% of the current wage rate ($18.50). To calculate the percentage increase, we divide the increase by the current wage rate and multiply by 100: ($2.75 / $18.50) * 100 ≈ 14.9%.

To determine the additional cost to Sylvia's annual wages budget, we need to know the total number of hours worked by the lead lathe tech in a year. Let's assume the lead lathe tech works 40 hours per week and there are 52 weeks in a year, resulting in a total of 2,080 hours.

To calculate the annual cost of the wage increase, we multiply the hourly increase ($2.75) by the total number of hours worked (2,080): $2.75 * 2,080 ≈ $5,720.

Therefore, the 14.9% increase in the lead lathe tech's hourly wage will cost Sylvia an additional $5,720 in her annual wages budget, excluding benefits or taxes.

An object moves in simple harmonic motion with period 8 minutes and amplitude 15m . At time t=0 minutes, its displacement d from rest is 0 m, and initially it moves in a negative direction. Give the equation modeling the displacement d as a function of time t .

Answers

Answer: \(d=-15sin\frac{\pi }{4}t\)

Step-by-step explanation:

The object is at equilibrium (\(d=0\)) when \(t=0\), so you use the equation \(d=asin(x)t\). The amplitude \(a\) is 15, and it represents the maximum displacement from 0.

To find \(x\), use the formula for the period: \(\frac{2\pi }{x}\). The period is 8 minutes, so you set up the formula  \(\frac{2\pi }{x}=8\) and solve for \(x\).

\(x=\frac{\pi }{4}\)

Because the object initially moves in a negative direction, the equation should have a negative in front.

Therefore, the answer is \(d=-15sin\frac{\pi }{4}t\)

Answers

"The speeds in race a are likely to be near 145 mph and the speeds in race b are likely to be near to 153 mph" correctly describes the consistency of the speeds of the cars in the two races.

Based on the given information, the box plot for race A has a larger range of speeds (from 120 to 170 mph) compared to the range of speeds in race B (from 125 to 165 mph). The box plot for race A also has a larger interquartile range (from 143 to 165 mph) compared to the interquartile range in race B (from 140 to 150 mph). However, the median speed in race A (153 mph) is lower than the median speed in race B (145 mph).

Therefore, it is not accurate to say that the speeds in race A are likely to be near 170 mph and the speeds in race B are likely to be near 165 mph. Likewise, it is not accurate to say that the speeds in race A are likely to be near 120 mph and the speeds in race B are likely to be near 125 mph.

The correct answer is that the speeds in race A are likely to be near 145 mph and the speeds in race B are likely to be near 153 mph. This is because the medians of the two box plots are relatively close to each other, and the box plot for race B has a smaller range and interquartile range, indicating greater consistency in the speeds of the cars in that race compared to race A.
