The cost of 8 pens is $2. 50. How much will 2 dozen cost?.
Answer:
$ 7.5
Explanation:
1. Common way:
if one pen costs $ x
8x=2.5
x=0.3125
2 dozen = 24
24*0.3125=7.5
2. shortcut:
2 dozen = 24 = 3 times of 8
because 8 pens cost $2.5, 2 dozen pens cost 3 times of $2.5, thus, $7.5
Write a function named test_sqrt that prints a table like the following using a while loop, where "diff" is the absolute value of the difference between my_sqrt(a) and math. Sqrt(a).
The function illustrated the use and the application of the while loops
While loops are used to perform iterative operations
The test_sqrt function in Python is as follows:
#This imports the math module
import math
#This defines the test_sqrt function
def test_sqrt():
#This initializes variable a to 1
a = 1
#The following is iterated for the values of variable a from 1 to 25
while a<=25
#This prints the required output
print('a =', a,'| my_sqrt(a) =',my_sqrt(a),'| math.sqrt(a) =', math.sqrt(a),'| diff =', abs(math.sqrt(a)-my_sqrt(a)))
#This increments a by 1
a = a + 1

In order to clear out room for new merchandise, james decided to mark down some of the items for sale in his electronics store. He marked down dvd players by 36%, and he marked down stereo tuners by 22%. If dvd players cost $41. 60 after the markdown and stereo tuners cost $69. 42 after the markdown, which item’s price was reduced by more, and by how many dollars more was it reduced? round all dollar values to the nearest cent. A. The dvd player’s price was reduced by $3. 82 more than the stereo tuner’s price. B. The dvd player’s price was reduced by $27. 82 more than the stereo tuner’s price. C. The stereo tuner’s price was reduced by $0. 29 more than the dvd player’s price. D. The stereo tuner’s price was reduced by $27. 53 more than the dvd player’s price.
The dvd player’s price was reduced by $3. 82 more than the stereo tuner’s price.
Let the cost price of dvd players be D.Let the cost price of stereo tuners be S.Given the following data:
Markdown for dvd player = 36%Markdown for stereo tuner = 22%Markdown cost for dvd player = $41.60Markdown cost for stereo tuner = $69.42To determine which item’s price was reduced by more, and by how many dollars:
First of all, we would calculate the cost price of each item.
For dvd players:
Note: You'll pay 64% since it was markdown by 36%.
[tex]\frac{64}{100} \times D = 41.60\\\\64D=41.60 \times 100\\\\64D=4160\\\\D=\frac{4160}{64}[/tex]
D = $65
Reduction: Dvd player = [tex]65-41. 60=[/tex] $23.40
For stereo tuners:
Note: You'll pay 78% since it was markdown by 22%.
[tex]\frac{78}{100} \times S = 69.42\\\\78S=69.42 \times 100\\\\78S=6942\\\\S=\frac{6942}{78}[/tex]
D = $89
Reduction: Stereo tuner = [tex]89-69. 42=[/tex] $19.58
Now, we can calculate the difference in reduction of the cost price of both items:
[tex]Difference = 23.4 -19.58[/tex]
Difference = $3.82
Therefore, the price of the dvd players was reduced by $3. 82 more than the price of the stereo tuners.

A particle moves along the curve y = 4x2 + 1 in such a way that the x value is increasing at the rate of 2 units per second. At what rate is y changing when x = 1?.
By differentiating both sides of y = 4x² + 1 with respect to time t, we have
dy/dt = 8x dx/dt
If the x value changes at a rate of +2 units/second (that is, dx/dt = 2) at the moment x = 1, then the y value changes at a rate of
dy/dt = 8 • 1 • 2 units/s = 16 units/s

A mixture of iron, salt, and sand can be separated using a magnet, water, a filter, and a hot plate. This separation _____.
Answer:
i think mixture
Explanation:
sorry if it wrong(tried my best)
Answer:
This is an example of a mixture that can be separated with simple separation techniques based on the physical properties of the mixtures. Magnetism, and filtration and evaporation
Iron is a magnetic material, but salt and sand are not, therefore, the iron can be separated from the mixture with the use of a magnet.
Salt and sand are mixable. Salt is soluble in water, but sand is not. Therefore by adding the sand and salt to water, the salt will dissolve,in the water(solvent) to form a salt solution. But the sand can be separated out of the solution by filtration with the filter paper inserted into a funnel which allows the salt solution to pass through while restricting the sand.
The sand would be removed by the filter paper, while the solution passes through.
The salt solution and some sand residues are placed in an evaporating dish and heated at low temperatures. The water from the solution evaporates, leaving the salt behind.
