The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.

Molodets [167]

Answer:

$68.25

Step-by-step explanation:

1. First, to find the cost of one sweatshirt, we multiply 175 by 13, and then divide by 100.

$175 * 13 = 2275$
$2275/100=22.75$

2. Now, we know that one sweatshirt costs $22.75. To find the cost of three sweatshirts, we multiply 22.75 by 3.

$22.75 * 3$
$68.25$

Therefore, the cost of 3 sweatshirts is $68.25.

Which of the functions have a range of all real numbers? Check all that apply. A. y = sec x B. y = csc x C. y = tan x D. y = cot

Nastasia [14]

Answer:

Option C and D that is y= tan x and y= cot x

Step-by-step explanation:

The range is the values of y means the values that y can take in a function:

So, range of tan x and cot x are all real numbers.

Period of tan x is $\pi$

Period of cot x is $\pi$

Option A and B that is secx and csc x are discarded

Students in a class are asked to stand in ascending order according to their heights for the annual class photograph. Determine

horrorfan [7]

Answer:

The function in Python is as follows:

def heightChecker(heights):

expected = []

count = 0

for i in range(len(heights)):

expected.append(heights[i])

expected.sort()

for i in range(len(heights)):

if expected[i] != heights[i]:

count+=1

return count

Step-by-step explanation:

Required

Function to return the number of out of position students

See comment for complete question

This defines the function. It receives the heights as a parameter, from the main

def heightChecker(heights):

This initializes a list, (expected list)

expected = []

This initializes the count of out of position students

count = 0

This iterates through the original list

for i in range(len(heights)):

The list item is then appended to the expected list

expected.append(heights[i])

This sorts the expected list in ascending order

expected.sort()

This iterates through the original and the expected lists

for i in range(len(heights)):

If list elements at the same index are not the same, count is incremented by 1

if expected[i] != heights[i]:

count+=1

This returns count

return count

Solve each equation.SHOW work plz

Studentka2010 [4]

$3 \frac{1}{2} r = 28 \\ \frac{7}{2} r = 28 \\ \frac{ \frac{7}{2} }{ \frac{7}{2} } r = \frac{28}{ \frac{7}{2} } \\ r = \frac{ \frac{56}{2} }{ \frac{7}{2} } \\ r= \frac{56}{7}$

$1 \frac{1}{2} c =6 \\ \frac{3}{2} c= \frac{12}{2} \\ \frac{ \frac{3}{2} }{ \frac{3}{2} } c= \frac{ \frac{12}{2} }{ \frac{3}{2} } \\ c= \frac{ \frac{12}{2} }{ \frac{3}{2} } = \frac{12}{3} =4 \\ c=4$
