The volume of solution in a test tube is measured to be 0. 0067 liter. Which digits in the measurement are significant figures?.
Answers
Answer:
6 & 7
Explanation:
Given data:
Volume of solution measured = 0.0067 L
To determine:
The number of significant figures
Significant figures are the number of digits that accurately describe a measured value.
As per the rules:
All non-zero digits are significant
Leading zero's i.e. the zero's after a decimal which comes before a non-zero digit are not significant
Hence in the given value 0.0067, there are 2 significant figures (6 &7)

On the upper surface of Jupiter’s atmosphere, the attractive force of
gravity is 2.5 times that on Earth. What would a bathroom scale show
if a 50-kg person were weighed on Jupiter?
Answers
A bathroom scale on Jupiter would show a weight of 125 kg for a 50-kg person.
On the upper surface of Jupiter's atmosphere, where the attractive force of gravity is 2.5 times that on Earth, a bathroom scale would show a different weight for a 50-kg person compared to Earth. To calculate the weight on Jupiter, we can use the formula:
Weight on Jupiter = Mass × Acceleration due to Gravity on Jupiter
The acceleration due to gravity on Jupiter is 2.5 times that on Earth, so we can multiply the person's mass by this factor:
Weight on Jupiter = 50 kg × 2.5
Weight on Jupiter = 125 kg
Therefore, a bathroom scale on Jupiter would show a weight of 125 kg for a 50-kg person. It's important to note that this weight measurement is relative to Jupiter's gravity and may not reflect the actual mass of the person.

Dan's motorcycle tank holds 6 1/2 gallons of gas. There are 3 5/8 gallons of gas currently in the tank. How much more
gasoline will it take to fill the tank? (Simplify your answer and write it as a mixed number.)
Answers
Answer:
2 7/8
Explanation:
You have to subtract the two numbers to find how much more gas you need to fill the tank.
First, subtract the 6 and 3, getting 3. You then have to subtract the 1/2 and 5/8, meaning the denominators have to be the same to be able to subtract them. So you make the 1/2 to 4/8 by multiplying 4/4 to the numerator and the denominator. You keep the 5/8 because now both fractions have the same denominator. So then you subtract 4/8 and 5/8 which is -1/8.
But we still have the 3, which you can take the -1/8 from, getting 2 and 7/8 because 8/8 is the same as a whole.
Hope this was helpful and let me know if it could be clearer!
The amount of gasoline will it take to fill the tank is 2 7/8.
What is gasoline?Gasoline is defined as a supplementary fuel that is high in energy and can be used as a form of cash. Many different compounds that include hydrogen and carbon are combined to make gasoline. A typical gasoline mixture typically contains about 150 different hydrocarbons, including butane, pentane, isopentane, and the BTEX compounds.
First, subtract the 6 from the 3 to arrive at 3. The 1/2 and 5/8 must then be subtracted, so the denominators must match for this to be possible. Therefore, you multiply 4/4 by the numerator and denominator to create the 1/2 to 4/8. Since both fractions now have the same denominator, you preserve the 5/8. So you take out 4/8 and 5/8 to get -1/8. However, the 3 remains, from which you can subtract 1/8 to get 2 and 7/8 because 8/8 is a whole that is the same.
Thus, the amount of gasoline will it take to fill the tank is 2 7/8.

Consider the following figure ABDC with diagonal BC. Sides AB and DC are congruent angle A is congruent to angle D and sides AC and DB are congruent
Answers
Quadrilateral ABCD is both a parallelogram and a rhombus.
The figure ABDC with diagonal BC, with the congruent sides AB and DC, angle A is congruent to angle D, and sides AC and DB are congruent is a parallelogram. This is based on the definition of a parallelogram which is a quadrilateral with opposite sides that are parallel and congruent to each other.
Also, opposite angles of a parallelogram are congruent. Therefore, angle A and angle C are congruent. Additionally, angle B and angle D are also congruent because they are opposite angles of a parallelogram.The diagonal of a parallelogram cuts it into two congruent triangles.
Triangle ABD and triangle CBD are congruent triangles, since their sides are congruent, and angles A and D, and angles B and C, are congruent by the given information.
Therefore, their included angles ABD and CBD are also congruent. Because their opposite sides are congruent, quadrilateral ABCD is a rhombus. A rhombus is a parallelogram with all sides congruent. This implies that sides AB, BC, CD, and DA are all equal.
In conclusion, quadrilateral ABCD is both a parallelogram and a rhombus.

Answers
Answer:
1. 66.6%

Explanation:
percent of decrease= (new - old) /old
1. Chad's play time decreased by 66.66%.
2. Karen's number of Eevees decreased by 71.42%.
3. The price of a bag upgrade decreased by 37.5%.
How do we calculate?1.
Chad's original play time was 3 hours per day. His new play time is 1 hour per day. The percent decrease is:
(Original - New) / Original * 100%
= (3 - 1) / 3 * 100%
= 2 / 3 * 100%
= 66.66%
2.
Karen's original number of Eevees was 7. Her new number of Eevees is 2. The percent decrease is:
(Original - New) / Original * 100%
= (7 - 2) / 7 * 100%
= 5 / 7 * 100%
= 71.42%
3.
The original price of a bag upgrade is 200 coins. The sale price is 125 coins. The percent decrease is:
(Original - Sale) / Original * 100%
= (200 - 125) / 200 * 100%

what volume would be occupied by 4.8 g of oxygen gas at 0.50 atm and 133 °c? (o: 15.999)
Answers
The volume occupied by this oxygen gas is equal to 10.0 Liters.
Given the following data:
Mass of oxygen gas = 4.8 gramsPressure = 0.50 atmTemperature = 133°C to Kelvin = \(273 +133=406\;K\)Molar mass of oxygen gas = \(2 \times 15.999\) = 31.998 g/mol.Scientific data:
Ideal gas constant, R = 0.0821 L⋅atm/mol⋅KTo determine the volume occupied by this oxygen gas:
First of all, we would calculate the number of moles of oxygen gas;
\(Number\;of\;moles = \frac{Mass}{molar\;mass}\\\\Number\;of\;moles = \frac{4.8}{31.998 }\)
Number of moles = 0.15 moles.
Now, we can determine the volume by using the ideal gas law equation;
\(V = \frac{nRT}{P}\)
Where;
P is the pressure.V is the volume.n is the number of moles of a gas.R is the ideal gas constant.T is the temperature.Substituting the given parameters into the formula, we have;
\(V =\frac{0.15 \times 0.0821 \times 406}{0.50} \\\\V =\frac{4.99989}{0.50}\)
Volume, V = 9.9998 ≈ 10.0 Liters.
