Step-by-step explanation:

d = 16

r = d/2 = 8

Formula:

SA = 2πr² + 2πrh

SA = 2(3.14)(8²) + 2(3.14)(8)(14)

SA = 2(3.14)(64) + 2(3.14)(8)(14)

The Bremen City School System is opening an all girls academy next school year. The girls choose one top (Green or Yellow), one pant (Khaki or Blue, and one pair of shoes (dress or white), What is the probability of choosing white shoes and a green shirt?

Answers

Answer:

0.25 = 25% probability of choosing white shoes and a green shirt

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

In this question:

The probability of choosing a shoe is independent of the shirt. So we find each separate probability, and then multiply them.

Probability of choosing white shoes:

2 shoes option, one of which is white. So

[tex]P(A) = \frac{1}{2}[/tex]

Probability of choosing a green shirt:

2 shirts options, one of which is green. So

[tex]P(B) = \frac{1}{2}[/tex]

What is the probability of choosing white shoes and a green shirt?

[tex]P(A \cap B) = P(A)*P(B) = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}[/tex]

0.25 = 25% probability of choosing white shoes and a green shirt

carline drives 25 minutes to the store. it takes her 3 minutes to walk in the store from the parking lot. If carline spends 5 hours and 36 minutes traveling to the store and back in one month, how many round trip visits to the store does carline take to the store each month

Answers

Answer:

6 round trip visits

Step-by-step explanation:

25 min drive to the store + 3 min to walk in the store + 3 min to walk back to car + 25 min to drive home = 56 total minutes for one round trip.

5 hours and 36 minutes = (5x60)+36 minutes=336 minutes

336 minutes/56 min per trip = 6 round trips

Emilio represents the perimeter of the triangle with the equation
(5w - 13) + (2w + 6) + 2(5w + 15) = P, where P is the perimeter of the triangle.
Which equation is correctly solved for w?

Answers

Answer:

A

Step-by-step explanation:

1) multiply 2 for 5w and 15

5w -13 + 2w + 6 + 10w + 30 = P

2) sum the therms with w and the term without it

17w + 23= P

3) add -23 at the two terms

17w + 23 - 23= P - 23

17w = P - 23

4) divide the two terms by 17

w = (P-23)/17

Which ones are functions and which ones are not

Answers

Answer:

For the graph part, A is not a function and B is a function. For the bottom part, A is a function and B is not a function.

Step-by-step explanation:

Top

A is NOT a function because it had failed the vertical line test, meaning that it has multiple outputs for each input which makes it not successful when taking the vertical line test. B is a function since it passed the vertical line test. Always use the vertical line test to see whether or not the graph met the requirement of having the input have one output.

Bottom

A is a function because the input contains one output. B is NOT a function since 5 contains 2 different outputs.

The outputs can be with multiple inputs, whereas the inputs cannot be with multiple outputs since they wouldn't meet the requirement during the vertical line test.

What is x and y??

Answers

9514 1404 393

Answer:

x = 90y = 64

Step-by-step explanation:

If we take the arcs to mean that those angles are congruent, then the sum of exterior angles is ...

  x° +2y° +75° +67° = 360°

  y = 109 -x/2 . . . . . . subtract non-x terms and divide by 2

Because x° forms a linear pair with a right angle, we know ...

  x° = 180° -90° = 90°

Then ...

  y = 109 -90/2 = 64

The values of x and y are 90 and 64, respectively.

The graph of function g is graph Z because the graph of function g is the result of a horizontal compression applied to the graph of function f

How to determine the function g(x)?

Function f(x) is given as:

[tex]f(x) = (\frac 12)^x[/tex]

Function g(x) is given as:

g(x) = f(kx)

The above represents a horizontal compression of function f(x) to form function g(x)

The graph that represents a horizontal compression is graph Z
