To write 149600000000 in standard form, we need to move the decimal point to the left or right so that there is only one non-zero digit to the left of the decimal point. 149600000000 in standard form would be written as 1.496 x 10^11.
To arrive at this form, we move the decimal point 11 places to the left (since there are 11 zeros in 149600000000) and add the power of 10 notation, indicating that we moved the decimal point 11 places to the left. The number 1.496 is the coefficient and 11 is the exponent. This way, we get 1.496 x 10^11 which is the standard form of 149600000000.
Standard form, also known as scientific notation, is a way of expressing a number in a compact and efficient manner. It is typically used for very large or very small numbers. To write a number in standard form, the decimal point is moved so that there is only one non-zero digit to the left of the decimal point. The number of places the decimal point is moved is indicated by a power of 10

What is the rule for a 45 45 90 special right triangle choices are given by the order of leg leg hypotenuse leg?.
For each 45-45-90 triangle, the period of the hypotenuse equals the length of the leg expanded via the square root of 2. That is the 45-45-90 Triangle Theorem.
A triangle is a polygon with three edges and 3 vertices. The terminology for categorizing triangles is greater than thousand years vintage, having been described at the very first web page of Euclid's elements.
In Euclidean geometry, any 3 elements, at the same time as non-collinear, determine a very precise triangle and simultaneously, a unique plane (i.e. a -dimensional Euclidean area). In special words, there's exceptional one plane that includes that triangle, and each triangle is contained in some plane. If the complete geometry is best the Euclidean plane, there is the fine one aircraft and all triangles are contained in it; however, in better-dimensional Euclidean areas, this isn't actual. this text is prepared triangles in Euclidean geometry, and specifically, the Euclidean plane, besides in which otherwise said.

DIG DEEPER There is a total of 4,752 passengers on 3 subway
trains. Each subway train has 8 cars. The number of
passengers in each car is the same. How many
passengers are in each car?
There are 198 passengers in each car.
What is division?
The division is one of the four basic mathematical operations of arithmetic, along with addition, subtraction, and multiplication. It is the inverse operation of multiplication.
To determine the number of passengers in each car, we need to divide the total number of passengers by the total number of cars.
We know that:
There are 4,752 passengers in total
There are 8 cars per train and 3 trains
So, the total number of cars is 8 cars/train x 3 trains = 24 cars
To find the number of passengers per car, we divide the total number of passengers by the total number of cars:
4,752 passengers / 24 cars = 198 passengers per car.
Hence, there are 198 passengers in each car.

What is the lowest whole number side length in inches that would ensure the triangle is an obtuse triangle?.
Answer:
24 inches.
Step-by-step explanation:
In order for a triangle to be obtuse, one of its angles must be greater than 90 degrees. In a right triangle, the angle opposite the hypotenuse is always 90 degrees, so in order for the triangle to be obtuse, the hypotenuse must be the longest side.
To find the lowest whole number side length in inches that would ensure that the triangle is obtuse, we can use the Pythagorean theorem. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides.
a^2 + b^2 < c^2
If we take the base 48cm and convert it to inches, 48cm = 48*0.393701 = 18.897638 inches
So the base is 18.897638 inches.
Now we have to find the lowest whole number side length of c so that:
18.897638^2 + b^2 < c^2
358.565744 + b^2 < c^2
We can see that the lowest whole number of c is 24 inches.
So, the lowest whole number side length in inches that would ensure that the triangle is obtuse is 24 inches.

determine if the two lines 7x-3y=-21 and y= "-3/7x+5" are parallel, perpendicular or neither
Answer:
They are perpendicular!
Step-by-step explanation:
Get 7x-3y=-21 into y=mx+b format.
7x-3y=-21 Bring 7x to the other side
-3y=7x-21 Divide -3 by both sides, it cancels out on the y's side.
y=-7/3x+7 Two negatives equal a positive, that it why 7 is positive.
y=-7/3x+7 is the line, the other is y=-3/7x+5
The slope of this line is -7/3 , the slope of the given line is -3/7.
Lines are perpendicular if the slopes are opposite reciprocals, such as this.
So, while they intercept at different points on the y-axis, they will intersect at some point! This makes them perpendicular.

Describe fully the second transformation.

It is a translation by vector
(?)
The second transformation that is applied to rectangle A B C D is a translation.
Explain about fully the second transformation:A translation is a transformation that moves an object a certain distance in a certain direction without changing its size or orientation. In this case, the translation is represented by a vector, which is a mathematical object that has both magnitude and direction. The vector for this translation would have the form (x, y), where x and y are the horizontal and vertical distances that the object is moved.In the case of rectangle A B C D, since all points on AB are invariant, it means that the translation vector has the same magnitude in the horizontal direction as it does in the vertical direction. This is why the vector for the translation is represented by (?), as the values of x and y are not given. The only thing that is specified in the problem is that the translation vector moves the rectangle in a direction that is different from the reflection line y = k, as there are no other invariant points.To learn more about second transformation refer to;

There was 1200 men and 800 women at the funfair in the morning
What is an equation?An equation consists of numbers and variables linked together by mathematical operations to form an expression.
Let x represent the number of men and y represent the number of women in the morning.
There are 400 more men than women at a funfair in the morning. Hence:
x = y + 400
x - y = 400 (1)
In the afternoon 2/5 of the men and 1/4 of the women left the funfair. hence:
number of men remaining = x - (2/5)x = (3/5)x
number of women remaining = y - (1/4)y = (3/4)y
There were 120 more men than women remaining at the funfair. therefore:

Trigonometry is a branch of mathematics that deals with the relationships between the angles and sides of triangles. One of the main uses of trigonometry is to calculate distances in a triangle when the lengths of two sides and the measure of the angle between them are known.
We can calculate this by using the formula:
Distance = (tower height) / (tan(angle of depression))
Distance = (83 ft) / (tan(49))
Distance = 40.6 ft (rounded to the nearest tenth)
Therefore, Julie is approximately 40.6 ft away from the base of the tower.

What is the difference between greatest 6 digit number and smallest 6 digit number?.
The difference between the greatest 6-digit and smallest 6-digit numbers is 899999.
The aim is to find the smallest and largest 6-digit numbers, and then we need to find how many numbers are between these two values.
Let's start by finding the smallest 6-digit number.
We know that 0 is the smallest digit that can not be used in the highest place value, so we will consider the next smallest digit; that is, 1 and 1 can be used in the highest place value.
Thus, we can create the required 6-digit smallest number with 0 and 1.
Hence, the smallest 6-digit number is 100000.
Now, we will discover the largest 6-digit number.
As we know, the largest digit is 9, which can be used anywhere. So, we will form the largest 6-digit number with the digit 9.
Thus, the largest 6-digit number is 999999.
Next, we need to find the difference between these two values.
So, we can determine the difference between the smallest 6-digit number and the largest 6-digit number by subtracting the smallest from the largest.
Thus, we get,
⇒999999−100000
⇒899999
Hence, 899999 is the difference between the smallest 6-digit and the largest 6-digit numbers.

y = 2.5 x + 10
So, we have to find the length of line segment from x = 0 to x = 16.
so when x = 0 ,
y = 0+10
y = 10
and when x=1
y = 2.5*1+10
y=12.5
and similarly
when x = 2
y = 2.5* 2 + 10
y = 15
So, like this the sequence will be goin on y = 10 , 12.5 , 15 , 17.5 and etc .
Hence, The length of the segment is 10,12.5 , 15,.. when x is from x = 0 to x = 16.
