A very flexible helium-filled balloon is released from the ground into the air at 20. ∘c. The initial volume of the balloon is 5. 00 l , and the pressure is 760. Mmhg. The balloon ascends to an altitude of 20 km , where the pressure is 76. 0 mmhg and the temperature is − 50. ∘c. What is the new volume, v2 , of the balloon in liters, assuming it doesn't break or leak?
The new volume, v2, of the balloon in liters, assuming it doesn't break or leak, is 38.0546 L. To perform the calculation we will use the Boyle-Gay-Lussac law gas equation.
What is the Boyle-Gay-Lussac law?It is shown that the volume of the gas is inversely proportional to its pressure, while its volume is directly proportional to its temperature and constant pressure.
P1 x V1/T1 = P2 x V2/T2P1= Initial gas pressure
V1= Initial gas volume
P2= Final gas pressure
V2= Final volume of gas
T1= Initial gas temperature (Kelvin)
T2= Final gas temperature
Substituting the values in the formula, we have:
760 x 5 / 293 = 76 x v2 / 223 v2 = 38.0546 LFind out more about gas equation here:

Black figure painting is ____________________ a. A hard, white, translucent ceramic that is made by firing kaolin and other materials. B. An advanced technique allowing for more detailed figures. C. A process in which the outside rim is designed with geometric patterns consisting of horizontal and vertical lines. D. An ancient greek technique in which the figures appear as black silhouettes on red background. Please select the best answer from the choices provided a b c d
Black figure painting is an ancient Greek technique in which the figures appear as black silhouettes on red background. The correct option is D.
What is silhouettes?The term "silhouettes" describes how an object or a person appears against a lighter background with black edges or shapes.
In the ancient Greek art form known as "black figure painting," the figures are shown as black shadows against a background of red.
This method, which was mostly employed between the seventh and fifth centuries BCE, was ultimately superseded by the red-figure method.
Ancient Greeks employed black figure painting as a significant form of artistic expression to show a variety of themes from daily life, mythology, and religious rituals.
The red clay behind the black slip was revealed by scratching away the black slip, which is how the black shapes were made.

A certain type of legal proceeding has three possible outcomes: in favor of party a, in favor of party b, or not in favor of either party. The outcomes are expected to be 40 percent, 20 percent, and 40 percent, respectively. A random sample of 40 cases is selected from a certain judge to investigate whether the judge’s outcomes are consistent with the expected outcomes. A chi-square goodness-of-fit test is conducted, and the value of the chi-square test statistic is χ2=9. 19 with a corresponding p–value of 0. 1. Assuming the conditions for inference were met, which of the following is the correct interpretation of the p–value?
Answer:
D) If the null hypothesis is true, there is a 1 percent chance of obtaining a chi-square value of at least 9.19.
Explanation:
Most of this AP question is fluff to confuse you, so make sure to emphasize the p-value and the actual question being asked.
For these interpretation problems, for chi-square GOF (goodness of fit) tests, the p-value is interpreted as such:
If the null hypothesis ([tex]H_o[/tex]) is true, there is a [[tex]p[/tex]-value] probability of obtaining a chi-square ([tex]x^2[/tex]) value of [test-statistic [tex]x^2[/tex]] or more extreme.
This answer choice fits the format the best, and is therefore the correct answer.

What can scientists infer about the observation of the fossils now found widely spaced across the globe that actually lived on the same early earth landmass?
Based on their observation of the fossils now found widely spaced across the globe, scientists inferred that the landmass split apart.
What is a fossil?A fossil can be defined as the mineral impression or remains of both living and non-living organisms that are generally considered to be prehistoric in nature.
This simply means that, fossils are obtained by scientists from ancient organisms such as Australopithecus, which is an ape that has the capability to walk on two (2) feet like humans, and it lived in trees.
In this context, scientists inferred that the landmass for organisms that lived on the same early Earth landmass was split apart based on their observation of the fossils, which are now found widely spaced across the globe.

A rectangle’s length is 2 units more than twice its width. Its area is 40 square units. The equation w(2w + 2) = 40 can be used to find w, the width of the rectangle. What is the width of the rectangle? 4 units 5 units 10 units 12 units.
Given the value of the area, the width of the rectangle whose length is 2 units more than twice its width is 4 units
Option A) 4 units is the correct answer.
What is Rectangle?A rectangle is simply a 2-dimensional shape which has opposite sides equal to each other and all four angles are right angles.
Area of a rectangle is expressed as;
A = l × w
Where l is length and w is width
Given the data in the question;
Width of the rectangle = w unitsLength of the rectangle L = 2w + 2 unitsArea of the rectangle A = 40 units²Value of w = ?
We substitute our given values into the expression above.
A = l × w
40 = (2w + 2) × w
w( 2w + 2 ) = 40
2w² + 2w = 40
2w² + 2w - 40 = 0
divide through by 2
w² + w - 20 = 0
Using the quadratic formula;
x = (-b±√(b² - 4ac)) / (2a)
a = 1
b = 1
c = -20
w = (-1±√(1² - ( 4× 1 × -20 ))) / (2×1)
w = (-1±√(1 + 80)) / (2)
w = (-1±√(81)) / 2
w = (-1 ± 9) / 2
Hence
w = (-1 + 9) / 2 or (-1 - 9) / 2
w = 8/2 or -10/2
w = 4 or -5
But the width the rectangle cannot be a negative number.

The graph below is used by company 2 to show the average monthly electric cost based on the electricity provider. A bar graph entitled average monthly electric cost has company on the x-axis and average monthly cost on the y-axis, from 95 to 125 in increments of 5. Company 1 has an average cost of 110, company 2 an average cost of 100, and company 3 an average cost of 120. How could the graph be redrawn so that the difference in monthly electric cost does not appear as great? the scale on the y-axis could be changed to 0–150. The scale on the y-axis could be changed to 100–120. The interval on the y-axis could be changed to count by 1s. The interval on the y-axis could be changed to count by 20s.
To make the monthly electric cost not to appear as great, the length of the bars can be reduced by redrawing the graph by making the following change:

1. The state fair sells food coupons for $2 each and
ride coupons for $3 each. If Marlon wants to buy at
least 15 coupons and spend no more than $40, what
is the largest number of ride coupons he can buy?
4.
Answer:
11
Explanation:
Food coupons is $2 each and ride coupons is $3 each.
If Marlon spends all $40 on ride coupons, he can buy 40/3 ~ 13 coupons which is less than 15 coupons that he wants.
If he gets only 12 ride coupons, he will have 40-3*12=$4 left which will let him buy 4/2=2 food coupons. Those add up to 12+2=14 coupons which is still less than 15 coupons.
So the largest number of ride coupons he can buy is 11.
