Answer: B
Step-by-step explanation: A Postulate is statement that is assumed true with no proof.
A hypothesis is an explanation provided for a phenomena. The correct option is B.
What is a Hypothesis?A hypothesis is an explanation provided for a phenomena. The scientific method demands that a hypothesis be testable in order for it to be considered a scientific hypothesis. Scientists often establish scientific hypotheses on past data that cannot be adequately explained by existing scientific ideas.
The one that cannot be used to explain why a hypothesis is true is a postulate. This is because a postulate is a statement that is considered to be true but has no supporting evidence.
Hence, the correct option is B.

use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet.
Use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet: TRUE
What are headlights?A headlamp is a lamp connected to the front of a vehicle to illuminate the road ahead. Headlamps are also commonly referred to as headlights, but in the most precise usage, the flashlight is the term for the device itself, and the headlight is the term for the beam of light produced and sold by the device. If you are driving with your high-beam lights on, you must dim them at least 500 feet from any oncoming vehicle to avoid blinding the oncoming driver. If you are within 200-300 feet of the vehicle you are following, you must use low-beam lights. When visibility is less than 500 feet and there is insufficient light/adverse weather, headlights must be turned on for 1/2 hour after sunset to 1/2 hour before sunrise.Therefore, the statement "use headlights between sunset and sunrise and at any time when visibility is less than 500 feet to 1000 feet" is TRUE.

Answer: 2: v = -26 | 3: k = 7 | 4: x = 3/14 |
Step-by-step explanation:
---------------------------------------------------------------------------------------------------
2: 4 + v/8 = 3/4
First we have to leave the variable "v" alone and we do the opposite on the other side.
So we do 4 + v/8 = 3/4 ----> v/8 = 3/4 - 4
---> v/8 = -3 1/4
next we do 8 * v/8 = -3 1/4 * 8
We get v = -26
---------------------------------------------------------------------------------------------------
3: 2/3 + 3/4k = 71/12
Subtract 2/3 from both sides
= 3/4k = 63/12
Reduce 63/12 to 21/4
= 3/4k = 21/4
Multiply each side by 4/3, the reciprocall of 3/4
then we get k = 21/3
Which means k = 7
---------------------------------------------------------------------------------------------------
4: 1/2 + 7/10x = 13/20
Subtact 1/2 from both sides
= 7/10x = 3/20
Multiply each side by 10/7, the reciprocal of 7/10
x = 3 * 10/20 * 7
= x = 30/140
= x = 3/14
Deb wants to organize a group of friends to go to a karaoke studio Friday night. She must pay $30 to reserve a private karaoke room plus $5 for each person in the group. She also wants to have snacks for the group at a cost of $2 per person. How many people can Deb invite in order to spend a total of $65?
Fill in the blanks to create an equation to represent the situation.
blank x + 2x + blank = 65
Based on the solution below, the number of people Deb can invite in order to spend a total of $65 is 5 people.
How do we use an equation to find a number?Given:
blank x + 2x + blank = 65 ............................... (1)
Where:
x = Number of people Deb can invite
First blank with x variable = 5; since Deb must pay an additional $5 for each person in the group
Second blank without x variable = 30; since Deb $30 to reserve a private karaoke room
Substituting the relevant values into equation (1) and solving for x, we have:
5x + 2x + 30 = 65
7x = 65 - 30
7x = 35
x = 35 / 7
x = 5

How can you rearrange two digits in the number 2,957,648 so that the value of the digit 4 is 10 times greater?
Answer:
2,957,468
Step-by-step explanation:
Each digit to the left is worth 10 times more than the same digit one place to the right.
If 2,957,648 becomes 2,957,468, the 4 moves from the tens place to the hundreds place, and now its value is 400 instead of 40, so it's 10 times greater.

Makayla mows two lawns the first lawn in 10 feet lawn and 7 feet wide the area of the second lawn is 7 times as big but has the same width as the first what it the length of the second lawn
The second lawn that Makayla mows has a length of 70 feet.
If the first lawn Makayla mows is 10 feet long and 7 feet wide, use the formula for the area of rectangle to know the area of the first lawn.
A = l x w
Area of first lawn = 10 feet x 7 feet
Area of first lawn = 70 ft^2
If the area of the second lawn is 7 times as big as the first, then the area of the second lawn is:
Area of second lawn = 7 x Area of first lawn
Area of second lawn = 7 x 70 ft^2
Area of second lawn = 490 ft^2
If the second lawn has the same width as the first, which is 7 feet, using the formula for the area of a rectangle, solve for the length of the second lawn.
A = l x w
Area of second lawn = l x w
490 ft^2 = l x (7 feet)
l = 70 feet

For a show during the halftime break up a football game a stage will be set up on the field the center of the stage is on the 35 yard line if the distance from the center to the outer edges is 11 yards which equation can be used to find the location of the outer edges of the stage
The absolute value equation that can be used to find the location of the outer edges of the stage is:
|x - 35| = 11.
What is the absolute value function?The absolute function is defined by:
|x| = x, x ≥ 0.|x| = -x, x < 0.It measures the distance of a point x to the origin, hence, for example, |2| = |-2| = 2.
For this problem, the outer edges are 11 yards away from the 35 yards line, hence the equation is:
|x - 35| = 11.
The solutions are given as follows:
x - 35 = -11 -> x = 24 yard line(first edge).x - 35 = 11 -> x = 46 yard line(second edge).More can be learned about the absolute value function at https://brainly.com/question/24734454

The correct option is the first one, (1.176*10¹) is 14.7 times larger than (8*10⁻¹)
How many times larger is the first number than the second number?Here we want to see how many times larger is (1.176*10¹) larger than (8*10⁻¹), we can see that both numbers are in scientific notation.
To check that, we just need to take the quotient between the two numbers, we will get:
(1.176*10¹)/(8*10⁻¹) = (1.176/8)*(10¹/10⁻¹)
(1.176/8)*(10¹/10⁻¹) = (1.176/8)*(10¹⁻⁽⁻¹⁾) = (1.176/8)*10² = 0.147*10²
Now, returning to standard notation, we can rewrite:
0.147*10² = 14.7

In the given word is “SASSAFRAS”. There are total 9 letters in which some letters appears several times, that is
S = 4 times.
A = 3 times.
F = 1 times.
R = 1 times.
We can the number of permutation to arrange this letter with the help of :
nPr = n! / (n - r)!
nPr = Permutation
n = Total number of objects
r = Number of objects selected
'!' = Factorial
Factorial :
Factorial (noted as “!”) is the product of all positive integers less than or equal to the number preceding the factorial sign. For example, 3! = 1 x 2 x 3 = 6.
So, nPr = 9!/(4!) (3!) (1!) (1!)
= (9×8×7×6×5×4×3×2×1)/(4×3×2×1)×(3×2×1)×(1)×(1)
= 3,62,880/ 24×6×1×1
= 3,62,880/144
